EDITORIAL Government of India, The Ministry of Commerce & Industry, Directorate General of Anti-Dumping & Allied Duties released their Final Findings on May 22nd, 2014, 156 Page Document recommending imposition of AntiDumping Duty on Imports of Solar Cells/Modules from Malaysia, China, Chinese PR & USA The ministry is recommending the imposition of AD duties of $0.81/W on a number of Chinese producers including JA Solar, Gold Poly, Wuxi Suntech Power, China Sunergy and the Baoding Tianwei Malaysian manufacturers, including Q-Cells Malaysia, will face AD duties of $0.62/W and Taiwanese producers – NeoSolar among them – will have to find $0.59/W. Having attempted to argue, unsuccessfully, thin film products were not interchangeable with multi-crystalline cells and should not be covered by the investigation, U.S. manufacturer First Solar got off comparatively lightly, with duties of $0.11/W recommended. The U.S. Trade Representative has filed two cases against India at the World Trade Organisation (WTO), complaining local content rules discriminate against U.S. solar companies. Those manufacturers were found to have dumped products in India with a dumping margin of 100-110% and a second group of Chinese manufacturers, found to have caused less damage, will be hit with AD tariffs of $0.64/W. Those manufacturers, including the five who proposed a price undertaking alongside famous industry names including Hanwha SolarOne, Chint Solar, LDK Solar and Yingli Energy, were found to have dumped products at 60-70% below a fair price. Chinese manufacturer Canadian Solar will also face an AD tariff of $0.64/W, having been found to have benefited from a 60-70% dumping margin. India also believes that anti-dumping duties imposed on Chinese solar producers by the European Union and the United States have further driven down the price of Chinese solar products, to the detriment of Indian suppliers. The ministry does not appear to have recommended back-dating the AD duties, however, stating penalties will be applied ‘from the date of notification to be issued in this regard by the central government.’ Opponents to the final decision pointed out that of the 39 Indian solar companies contacted by the authorities to comment on any injury dumping had caused them – after the original complaint by Indosolar, Jupiter Solar Power and Websol Energy System – only three responded. Critics of the probe claimed even those three respondents – Moser Baer Solar, Moser Baer Photovoltaic and Tata BP Solar – benefited from imports of the dumped goods in question, and should be ignored. The Indian Ministry of Environment and Forests and the Ministry of New and Renewable Energy both spoke out against the imposition of AD penalties with the latter claiming the country’s domestic content requirements – which stipulate a percentage of solar projects have to include home-grown materials – are sufficient to protect domestic manufacturing. The Indian Ministry of Commerce rejected a call for the state aid provided by the U.S. Export-Import Bank to American exporters to be used in the calculation of a fair price for U.S. solar goods. Investigators agreed to exclude Indian companies Moser Baer and Tata BP Solar from the definition of domestic industry after both admitted importing dumped products but dismissed claims there are 90 Indian solar product manufacturers, rather than the 42 mentioned by the original complainants in the case. The thorny question of whether the petitioners should not be considered domestic industry because of their status as Special Economic Zone (SEZ) and Export Oriented Units (OEU) was also debated. Opponents argued that, as both types of business are constituted as such to focus on exports, they cannot be considered domestic industry. But ministry of commerce officials dismissed the claim, stating such businesses are based in India, manufacture the goods in question in the country and sell them in India, in direct competition with Indian rivals. The Chinese-Canadian company attempted to argue its panels should be excluded from the anti-dumping investigation because of differences between them and Indian-made products. The arguments were ignored by ministry of commerce officials who described the modules in question as ‘innovations’ rather than different products and cited previous instances where EU investigations had included variations of products even if not manufactured in the EU. One of the thorniest arguments which raged during the Indian ministry of commerce’s anti-dumping (AD) investigation into cells and modules manufactured in China, Taiwan, Malaysia and the U.S., concerned whether thin film products should be considered ‘like products’ to crystalline ones and thus also subject to duties. Investigators decided both types of cells were comparable in physical and chemical characteristics, manufacturing process and technology, final functions and uses, product specifications, pricing, distribution and marketing and tariff classification.

EMAMI BIODIESEL: PERFECT FOR YOUR POCKET. PERFECT FOR THE PLANET. The rising costs of traditional fuels like petro-diesel have created an urgent requirement for an affordable, eco-friendly alternative. Emami Biotech Ltd. has fulfilled this need with the ideal replacement – Biodiesel. It extends machine life, reduces maintenance and is easier to handle and store. Emami’s biodiesel is backed by superior technology and production capabilities. Highlights of Emami’s biodiesel • Produced at state-of-the art multi-feed stock facility commissioned by Desmet Ballestra, a Belgian technology company. • The plant is capable of manufacturing biodiesel conforming to EU (EN14214) and BIS standards. • Low sulphur content; out-performs industry standards*. • Betters industry benchmarks in ash & moisture content, total contaminations and carbon residue indicators. • Regular exporter to many European countries. • ISCC Certification - It is the pre-requisite for export of biodiesel to Europe. ISCC is one of the leading certification systems for sustainability & greenhouse emmissions. USES OF BIODIESEL Vehicles: Can be used in every diesel engine powered vehicle. (Millions of miles were logged on biodiesel in EU nations). Farming and Industrial Equipments: Can be used for construction, mining, and farm machinery. Marine Vessels: Can be used in marine engines safely. Marine use is especially attractive due to the elimination of any possibility for contamination of waterways. Stationary Power Generation: With new power generation capacity coming online, biodiesel makes an attractive choice to meet the regulations. Many stationary applications require exhaust emission control system, which will work well with biodiesel. Boiler Fuel: Can be substituted easily for gas or fuel fired boilers. Hybrid Vehicles: With many states now mandating hybrid electric vehicles (including the fuel cell hybrid), biodiesel will make excellent reforming fuel. Agriculture Adjuvants: Biodiesel is used as a carrier for pesticides and fertilisers in agriculture sprays due to it being nontoxic and biodegradable. Solvents: Can be used as industrial solvents and as a replacement of high VOC containing petroleum solvents. With regulations driving the VOC contents lower for solvents used in industries, biodiesel offers an attractive solution. Lubricity Agent/Additive: Our biodiesel can also be used as a lubricity agent/enhancer in many applications. It is especially useful in marine applications where water contamination with petroleum lubricity agents can create problems. With the low-sulphur fuel regulation of the future, biodiesel can be used as a lubricity additive. 1-2% biodiesel added to diesel fuel can increase diesel lubricity by 65%. Textile Coning Oil: It is a suitable replacement of coning oil. Bio Jute Oil: It is used for processing of raw jute fibre. It is completely free from aromatic hydrocarbons. Metal Working Fluids: Used for metal-cutting oil to reduce environmental pollution and also used as coolant. Paint Industry: It can be used as drying oil for the paint industry. Fuel Oil: It can be used in gen set with the blend of diesel oil. It can also be used in boiler and road making equipment.
FEATURES
ADVANTAGES OF BIODIESEL
Environment Friendly
It is an environment-friendly fuel, the best alternative to common petroleum diesel. Biodiesel is 11% Oxygen by weight and contains no Sulphur. It produces approximately 80% lesser CO2 (Carbon Dioxide) and almost 100% lesser SO2 (Sulphur Dioxide) emission.
Credibility
It is a proven fuel with over 30 million successful US road miles and over 20 years of usage in Europe.
No Modification of Engine Required
Biodiesel is the only alternative fuel that runs in any conventional, unmodified diesel engine.
How to Use
It can be used alone or mixed in any ratio with petroleum diesel fuel. The most common blend of mixing is 20% biodiesel with 80% petroleum diesel, commonly known as B20 for transport vehicle. However, for a Static Engine, 100% biodiesel commonly known as B100 can be used.
Same Power Output
Biodiesel offers the same power output as petro-diesel fuel.
Extended Life of Engine
The use of biodiesel can extend the life of diesel engines because lubricates better than petroleum diesel fuel, while fuel consumption, auto ignition, power output, and engine torque remain unaffected. Biodiesel also has a cleansing effect on engine walls.
Safe to Handle & Store
Biodiesel is safe to handle and transport because it is as biodegradable as sugar, 10 times less toxic than table salt, and has a high flashpoint of about 1250C as compared to petroleum diesel fuel, which has a flash point of 550C.
Cost Advantage
Price of biodiesel is the same as that of petroleum diesel, but due to its properties, it increases the life of the engine and reduces the maintenance cost over the period of time.

Middle East and Africa Solar PV Demand to Grow by 50 Percent In 2014, According To NPD Solarbuzz Solar photovoltaic (PV) demand from the Middle East and Africa (MEA) region is set to grow 50 percent year-over-year in 2014. Between 2014 and 2018, annual PV demand will nearly triple as the MEA region becomes a key market for the global industry, according to findings in the latest NPD Solarbuzz Emerging PV Markets Report: Middle East and Africa. By 2018, annual PV demand in the MEA region is expected to reach 4.4 GW, with an upside potential of 10 GW. PV demand from the MEA region in 2013 grew by 670 percent, compared to 2012 when the region added approximately 140 MW. Previously, the region had a substantial share of small off-grid PV systems; however, in 2013, the on-grid segment became the main factor driving growth to more than 1 GW, with 1.6 GW forecast for 2014. In 2018, ground-mount 8
EQ May 2014
systems will account for over 70 percent of the market.Until now, PV growth in the MEA region has been predominantly driven by a small number of economically prosperous countries, in particular South Africa and Israel. Along with Saudi Arabia, these three countries are expected to offer stable demand levels within the MEA region over the next few years. “Solar PV represents an ideal renewable energy type across much of the Middle East and Africa,” noted Susanne von Aichberger, analyst at NPD Solarbuzz. “Even so, market drivers and constraints differ greatly between the two regions.”In most of the Middle East, renewable energy is seen as a means of preserving domestic oil and gas reserves. Middle East PV demand is forecast to reach 2.2 GW in 2018, with an
upside potential of 4 GW. Israel is projected to be the largest PV market in the Middle East in 2014, mainly through solar parks and rooftop systems, based on net-metering. Saudi Arabia’s ambitious renewables program will finally start to materialize this year, making it the largest PV market in the MEA region by 2016. Saudi Arabia is forecast to add 2.4 GW of new PV capacity between 2016 and 2018. Other key solar PV markets in the Middle East include the United Arab Emirates, Jordan, and Kuwait.With a severe shortage of electricity within Africa, in general, and large parts of the population of Sub-Saharan Africa having no access to electricity, solar PV is considered suitable for helping to stimulate social and economic development in the region. PV demand from Africa is forecast to reach 2.2
GW by 2018, with an upside potential of 6 GW. In 2014, African PV demand will continue to be dominated by South Africa, due to the construction of large-scale PV projects resulting from the Renewable Energy Independent Power Producer Procurement Program (REIPPP). “In the past 12 months, new plans for large PV projects have emerged across Africa, including the subSaharan countries of Cameroon, Swaziland, and Uganda,” added von Aichberger. “Announcements of PV projects in the 100 megawatts range have now become common, as a means of expanding power generation capacity quickly.”

China Hits EU With Final Duties On Polysilicon China imposed anti-dumping and anti-subsidy duties on imports of polysilicon from the European Union, the Commerce Ministry said on Wednesday, the latest move in a long-standing dispute over solar materials. Solar panels were at the centre of a trade row last year after the European Union decided to impose anti-dumping duties on panels made in China. Polysilicon is a raw material used in the manufacture of solar panels. The ministry had extended its investigation into European polysilicon by six months late last year, citing “complicated circumstances”, but imposed duties on South Korean and the U.S. polysilicon in January to protect its domestic solar producers.
Beginning on May 1 and lasting two years, anti-dumping duties of 42 percent will apply to German, Italian and Spanish companies, including Schmid Group, Joint Solar Silicon, MEMC Electronic Materials SpA and Siliken Spain, the ministry said in a statement on its website. The companies would also be subject to 1.2 percent anti-subsidy duties, it said. The ministry said it has spared one company, Wacker Chemie AG, from duties because of the firm’s “price commitments”. “If there is a violation of this price commitment or other termination of the price commitment, then anti-dumping duties will be levied according to the final ruling,” the ministry said. Relations between China and
the European Union had soured over the solar industry disputes. They have also been involved in disputes involving other industries, including wine. The European Commission, the EU’s executive body, had accused China of dumping billions of euros worth of solar panels in Europe below production costs. It had planned to impose heavy tariffs on Chinese solar panels but a majority of EU governments - led by Germany and wary of offending China and losing business - opposed the plan and sealed a compromise deal in July. Despite the resolution of that solar panels dispute, China pressed ahead with its investigation into European wine exports, saying it was a separate issue despite European
expectations that the inquiry would also be dropped. China and the EU reached a deal in the wine case days before China’s President Xi Jinping travelled to Europe in March, but trade woes between the two, from the solar industry to telecoms, persist. Reuters reported in April that the EU has cleared the imposition of hefty duties on Chinese imports of glass used in solar panels, saying it gets illegal subsidies and is sold at unfairly low prices that threaten European manufacturers. A majority of the EU’s 28 members backed the proposed duties, ranging from 17.1 percent to 42.1 percent, according to EU sources. (Editing by Robert Birsel)

The company will produce 240 mw solar photo voltaic cells and 100 mw photo voltaic modules at its plant in Sakoli in Bhandara district. This will be the Central government’s first project in Vidarbha and it can avail
subsidies from the National Clean Energy Fund (NCEF). MIDC has provided 480 acre land to BHEL for the project. The BHEL proposal, as a “mega project” was first sanctioned in January 2012 by the highpowered committee comprising chief secretary, ACS (planning) and ACS (Finance) , on condition that it will utilise the capital expenditure in five years, repay 20 per cent of the VAT in 15 years, electricity duty waiver for 15 years and complete stamp duty waiver. Union Minister for Heavy
industries Praful Patel, who is also the MP from Bhandara, wrote to the state government that more perks were necessary to make the project financially viable. However, the high-powered committee refused to grant any more concessions. In the meantime, Deputy Chief Minister Ajit Pawar asked the high powered committee to place the proposal before the Cabinet. In August 2013, BHEL increased its project cost from Rs 2,000 crore to Rs 2,450 crore and
sought more concessions and also promised more employment opportunities. The Cabinet sub committee proposed electricity concessions of Rs 5.61 per unit, a product purchase guarantee and equity share capital of Rs 680 crore to the project. However, the high powered committee on May three refused the concession of equity share but said the government will given only financial assistance from the national clean energy fund. Source:ET

& EQBusiness Financial Ind-Ra: Debt Structure And Amortisation Profile To Determine Debt-Worthiness Of Solar Power Projects Ind-Ra believes that the Viability Gap Funding (VGF) model for the batch I, phase II of the Jawaharlal Nehru National Solar Mission is prima-facie viable but needs the support of financial engineering techniques to enable timely debt service on these projects. The equipment costs, debt structure and the size of the viability gap funding (VGF) will drive the credit quality of these projects. Ind-Ra, in its analysis has concluded that the projects under this batch would need a
minimum VGF grant of 16% of the project costs (under certain set of assumptions) with an annual declared capacity utilization factor (CUF) of 19% to be able to achieve timely debt service. The optimum debt/equity mix is 69:31 to achieve a break-even debt service coverage ratio of 1.0x. VGF grants below 16% of project costs could be stressed to meet timely debt service. Besides the construction timeline, the projects would require an amortization period of around 13 years, taking into
account the seasonal variations involved in solar projects. Seasonal variations in CUF must form a part of the capital structure analysis in order to achieve success in these models. The tariff of INR5.45/kwh would add to stress unless backed by sizable VGF. Ind-Ra determines the minimal breakeven tariff (which would just about enable it to service debt) to be INR6.50/ kwh, in the absence of VGF.

Welspun Renewables Commissions One of Karnataka’s Largest 19 MW (DC) Solar Capacity Welspun Renewables Energy Private Limited (WREPL), India’s leading renewable energy generator commissions one of Karanataka state’s largest 19 MW (DC) solar capacity. Based in Chitradurga district the project was awarded as twin solar projects of 8 MW (DC) and 11 MW (DC). The 8 MW (DC) capacity was commissioned last year - four months in advance, while the balance 11 MW (DC) capacity has now been developed in less than three months and consequently 10 months ahead of schedule. An achievement, as most developers who had won projects in Karnataka Phase 1 solar bids are yet to commission theirs. While, in the 2nd phase of bids, out of 13 developers to whom the state had issued an LOI WREPL’s 11 MW (DC) project is first to be commissioned! Speaking on the occasion Mr. Vineet Mittal, Vice Chairman, Welspun Renewables Energy Pvt. Ltd. said “We are committed 18

to Karnataka’s energy security targets. As with our projects before, we have commissioned our 19 MW (DC) capacity much ahead of scheduled date; thereby fulfilling on our commitment to deliver environment friendly & efficient energy in the shortest possible time into the stare grids. The project is already touching high performance standard (CUF%) of 27%.” Karnataka is an energy deficit state and has been reeling under power cuts constantly. With this project in Chitradurga - for the next 25 years, the project will be annually feeding 30,724 units of clean emission free energy into the state grid. This is equivalent to powering 48,000 homes and mitigating 23,043 tones of CO2 emissions.The tracking system deployed at the site would track the path of the sun from
morning till evening. This system is expected to give a significant boost to power generation percentage in comparison to the fixed tilt system.The solar installation has been developed by Welspun Renewables Energy’s step down subsidiary Welspun Solar Kannada Pvt. Ltd. under the Karnataka Solar policy 2011-16. As per the PPA signed with Mangalore Electric Supply Company (MESCOM), the power plant was scheduled to begin commercial operations
only by March 2014. 11 MW (DC) was to be commissioned before 20-Jan-2015. Welspun Energy has so far built up more than 600 MW solar & wind energy capacity on-ground and of this 328 MW (DC) is already operational. The organization envisions developing power projects pan India, with existing projects located in high radiation zones like Gujarat, Rajasthan, Madhya Pradesh, Maharashtra, Andhra Pradesh, Tamil Nadu and Punjab.

equipment provider opens up possibilities for EPC contracts in new PV markets,” Berg remarked. “But because the Chinese domestic market will grow by 31 percent this year, TBEA is also set to keep its systems business growth focused on China.” Table 1 presents the IHS global ranking of solar system
IHS can spot those countries where PV deployment can take off quickly given the right conditions.” With 34 GW of announced projects in planning and 5 GW under construction, North America boasts the largest PV pipeline. This is due to both the large number of projects involved and the size of the projects
First Solar installed a total of 1.1 gigawatts of solar capacity last year, up from 516 megawatts (MW). In comparison, runnerup TBEA SunOasis installed 1.0 GW, up from 250 MW, as shown in the attached table. But with SunOasis projected to attain1.5 GW of installations this year compared to First Solar’s 1.3 GW, TBEA SunOasis has the potential to sail to the top among global PV integrators. These findings are contained in the report, “IHS PV EPC and Project Market Tracker,” from the Power & Energy service of IHS. “After a strong year of installing 22 percent of the non-residential PV capacity in the U.S. and Canada, First Solar remains focused on North America,” said Josefin Berg, senior analyst for solar demand at IHS. “Largescale projects in the U.S. will make up around 93 percent of the 1.3 GW worth of additions in 2014.” These projects, Berg said, were acquired in early-stage development and are now being constructed and sold primarily under U.S. investment tax-credit policies. To mitigate the risks that arise from dependence on one market, First Solar is building up a global project pipeline through acquisitions and joint ventures, with the company now also claiming

This year, the power equipment manufacturing group will continue growing its PV systems business, with expected additions to reach as high as 1.5 GW. While focusing on utility-scale opportunities in China, TBEA is also involved in power projects in markets such as Pakistan, where it is undertaking the construction of a 100-MW PV plant in 2014 and 2015. “TBEA’s global reach as a power

& EQBusiness Financial Solving India’s Renewable Energy Financing Challenge: Instruments to Provide Lowcost, Long-term Debt The government of India plans to more than double the renewable energy capacity installed in the country from 25 GW in 2012 to 55 GW by 2017. However, renewable energy is still approximately 52-129% more expensive than conventional power (CPI, 2014b). In our previous work (CPI, 2012), we found that the biggest barrier to renewable energy in India is the inferior terms of debt – i.e., high cost, short tenor, and variable rate – which raises the cost of renewable energy in India by 24-32% compared with similar projects in the US.
instrument, we also considered (4) potential to mobilize private capital, (5) potential to attract foreign investments; and (6) feasibility of implementation. The figure below presents our results.
While a number of fi nancing instruments that have been used elsewhere could contribute to solving the main problems in financing renewables in India, none are currently available. In this paper, we explore financing instruments, used in other regions as well as those that were recently introduced in India in other contexts that have the potential to provide and/or facilitate low-cost, long-term debt for renewable energy in India.
* The baseline cost is 12.8%, which is the average annual return of an “A” rated bond. + Actual cost reduction depends on the structure of the guarantee ~ We assume the developer avails an interest rate swap for foreign debt # Based on baseline foreign debt cost
We explored three categories of instruments used to finance renewable energy around the world: (a) instruments that provide access to previously untapped lowcost, long-term funds from domestic capital markets; (b) instruments that provide access to foreign debt; and (c) guarantee instruments that mitigate the risk associated with projects. We then further analyzed five instruments for: (1) their cost reduction potential, (2) their potential to increase tenor of funds, and (3) whether they provide fixed interest rates. For each 24

of 13%
Since each of these instruments represents a different kind of debt, we estimated the reduction in cost of debt for each instrument based on the typical baseline cost applicable for that particular instrument. The potential benefits from each of the instruments are as follows: Government bonds: A direct government borrowing and lending program, compared with a typical domestic loan that is available at 12.3% for 10 years, would reduce the cost of debt by up to 4.5 percentage points and increase tenor by up to 10 years, ultimately decreasing the delivered cost of renewable energy by approximately 25%. However, a direct government borrowing and lending program may crowd out private financing if not designed carefully. Infrastructure debt funds
(mutual funds): An infrastructure debt fund, compared with a typical domestic loan, would reduce the cost of debt by up to 3 percentage points and increase tenor by up to 5 years, which would reduce the delivered
cost of renewable energy by approximately 14.5%. Partial credit guarantees: Partial credit guarantees reduce the cost of debt by enhancing the credit rating of a project. By using a partial credit guarantee, an A-rated bond at 12.8% can be enhanced to AA, reducing the cost of debt by up to 1.9 percentage points, which when combined with a tenor increase of 5 years compared to domestic debt would reduce the delivered cost of renewable energy by approximately 10.5%. Partial risk guarantee: Partial risk guarantees attract foreign funds by mitigating political risks. A partial risk guarantee, for a typical foreign loan at 13% for 10 years, could reduce the cost debt by up to 1.8 percentage points and extend the tenor by up to 10 years, ultimately decreasing the delivered cost of renewable energy by approximately 12.7%. Exchange rate liquidity facility: An exchange rate liquidity facility offers a standby lower-cost credit line to mitigate currency depreciation risk for project developers who access
foreign loans.A liquidity facility, compared to a typical foreign loan at 13% for 10 years, would reduce the cost of debt by up to 1.4 percentage points and increase the tenor by up to 8 years, which would decrease the delivered cost of renewable energy by approximately 11.2%. T h e s e in s t r u m e n t s c a n potentially help mobilize domestic capital and foreign investment, while improving risk management. Ultimately, the selection of the most appropriate instrument(s) for solving India’s renewable energy financing challenge depends on policy priorities and implementation feasibility. The actual benefi t derived from these instruments depends on their design and implementation. The government of India should coordinate with financial institutions and research organizations on the selection, development, and implementation of these financial instruments. Depending on which instrument mixes seem most relevant to India, we recommend further analysis to examine the instruments in greater detail: for the direct government lending program, on the design of the program to identify checks and balances to limit crowding out private investment; for infrastructure debt funds, on how to increase effectiveness and suitability for renewable energy projects; for credit guarantee on project selection and cost of implementation; for risk guarantee, assessment of guarantee programs already implemented elsewhere in the world; and for exchange rate liquidity facilities, on feasible models for Indian conditions.

Green Bonds Could Cut India Clean-Energy Cost 25%: Report Funding renewable projects with Indian government-backed green bonds could lower the cost of clean power by as much as 25 percent, according to a study. The government could sell bonds and lend the proceeds to wind and solar farm developers. India could offer funds a third cheaper than commercial bank loans and for double the tenor as the government has the highest domestic credit rating, according to a report by the Indian School of Business and Climate Policy
Initiative, a San Francisco-based research firm. India, ranked Asiaâ&#x20AC;&#x2122;s third-most attractive country for renewable investments by Ernst & Young LLP this year, plans to double its clean-energy capacity to 55 gigawatts by 2017. Lack of affordable financing is an obstacle to reaching that target as the central bank is raising interest rates to combat inflation and commercial banks are wary about lending to new technologies.
The state-run Indian Renewable Energy Development Agency Ltd. raised about 7.2 billion rupees ($117.8 million) last month selling 10-, 15- and 20-year tax-free bonds to help finance clean-energy projects, according to data compiled by Bloomberg. In addition to green bonds, the government could step in with other financing instruments such as infrastructure debt funds, partial credit guarantees for projects and a low-cost
credit line to mitigate currency depreciation risk, the report said. Indian commercial banks offer 10-year loans with interest rates of about 12 percent to renewable plants. Such unfavorable terms add as much as 32 percent to the cost of renewable energy in India, Climate Policy and the Indian School of Business said in a separate report last month.

or various reasons, all of the present manufacturers of String inverters and Smart Inverter combination are not satisfying the Indian market’s specific requirements. We want to bridge this gap by designing and integrating the Smart Inverter based systems in India. One of specific needs of country was to stop the reverse flow of power from a grid tied system in case it was not being utilised by the load. As a result ACVA Solar Pvt. Ltd., a Baroda based company from Gujarat has tied up with DARFON, a Taiwan based company for their Micro Inverters, String Inverter and Smart Trimmer products. As a direct outcome the first system of 13 kWp using String Invertor plus Smart Trimmer combination has been installed over an Educational Institution since Jan. 2014. In this system 52 panels of 250Wp are connected with a 4 kW x 3 Nos. of Darfon String Inverters. These String Inverters are tied with Smart Trimmers which controls the output of the inverters to match the loads. Any excess energy during low/zero load hours is stopped by these Trimmer from flowing back to the grid. This operation is on real time bases and gives excellent reverse protection at a cost of minor grid power usage (for sensing purpose) in case of low loads (loads being lower than the generation). Full power of the system with inverter efficiency in excess of 97% gets fully utilised in case of full load conditions.

s the solar industry matures, a solution for commercial and utility power plants is needed that both addresses the fierce cost challenges in the PV market and which is global and easily adaptable to regional requirements. The MLX concept answers to these challenges. The MLX inverter concept builds on new ideas of how to optimize PVsystems. It draws on the advantages from both string inverters and central inverters, making it applicable in many commercial and utility size systems. Internally the plant will look like a decentral plant, with all the advantages of a string system. Seen from the outside the plant will resemble a central system, with a single point of access for all control and communication.
Why choose the MLX Concept? The MLX concept centers on a highly
The MLX Inverter •
The top-level efficiency of 98.6% of the MLX inverter already takes the internal consumption of the inverter into consideration (cooling, etc.). Therefore only electricity costs due to small loads, such as the monitoring hardware or the surveillance cameras need to be considered.
•
Designed for long strings (23-25, 60 cells, c-Si standard modules) it reduces losses and cabling costs onthe DC side.

Energy Management Control To Meet Minimum Technical Requirements In Photovoltaic Power Plants Víctor Andrés Díaz, José Ramón Gordillo, Carlos Infante, Manuel Lagares R&D Department
T
he increasing inclusion of renewable energy plants into National Electric Grids has driven regulatory agencies to the establishment of a set of requirements in order to ensure that these plants will help to achieve the whole grid stability. These sets of requirements to be met by the plants are named Minimum Technical Requirements (MTRs), and can be categorised as: •
Voltage Requirements
•
Frequency Requirements
•
Reactive Power Requirements
Depending on the country, MTRs must take into account additional devices are

needed to interconnect a PV plant to the electrical grid together with PV inverters. Among others, the use of energy storage elements as well as elements of reactive power compensation may be needed. Each set of requirements defines the engineering design of different elements of a power plant. These elements have to be developed in accordance with the needs of active and reactive power injection;in addition, they have to define communications architecture between the different elements

in order to ensure suitable response times. Main devices to meet Minimum Technical Requirements (MTRs) are: • PPC: Power Plant Controller The PPC is the main control system responsible ofgenerating control references Figure 2.

been successfully installed in a 37,8 MW CPV facility, following the MTRs set by the Main National Utility ESKOM. This PV plant implements the following controls. •
Voltage Control
•
Reactive Power Reference Control
•
Power Factor Control
•
Ramp Rate Control
•
Active Power Curtailment Control
Voltage, Power Factor and Reactive Reference Control System A constant voltage control is required. PPC must have a closed loop of VRS control, equivalent to the Automatic Voltage Regulator in conventional generators. The VRS controller regulation is based on closed loop actions with parallel reactive droop compensation. The VRS set-point must also be adjustable by the operator. In the example above mentioned in South Africa,constant power factor and fixed reactive power control are required. The PPC gives priority to each control, depending on the plant operator commands. Generally, voltage control is carried out by the PV inverter reactive capability. In other power plants, VAR compensator devices, such STATCOMs or capacitors banks, provide a source or a sink of reactive power if necessary. PV inverters and MTRs devices will receive a continuous external reactive reference. If capacitors banks are included, the PPC reactive control shall be able to manage these references and integrate them in output references and the command for the connection of the capacitors.Capacitors banks will be connected following a defined sequence, so they will give a reactive response depending on their capacity. Ramp Rate and Curtailment Control Active Power Curtailment is the limit
www.EQMagLive.com
Ramp Rate Control is required to guarantee a smooth transition from one power output level to another. The PV facility shall be able to control the rate of power output change during some circumstances, including: •
Rate of increase/decrease of active power due to irradiance
•
Rate of increase of power when an external curtailment of power output is released
•
Rate of decrease in power when an external curtailment limit is engaged
This ramp rate may apply both to the increase and decrease of power output and is independent of meteorological conditions.
ready to feed or store a specific amount of power at each moment. At this point, the state of charge (SOC) management becomes critical. The SOC management control will make the SOC value to be within a target band whenever possible. The way to achieve this objective is by adding a ∆P to the reference power that comes from the PPC ramp and frequency control algorithm.So PPC control strategy for SOC management must avoid the following situations:
Figure 4.PV Plant behavior with PPS
Frequency Response/Regulation:
•
Generally, the PV facility shall provide an immediate real power primary frequency response, proportional to frequency deviations from scheduled frequency, similar to governor response.
If PPS reaches to SOC maximum, the storage system is only available for feed power.
•
If PPS reaches to SOC minimum, the storage system is only available for storage energy.
The PPC has several possible modes of frequency control divided in two categories. The first category refers to a plant without storage systems where PPC can only deal with over frequency. The second category is designed for plants with storage systems where they will face both under frequency as overfrequency.
GPTech’s next control challenge In order to meet MTRs, increasing power when frequency deviation is negative or achieving ramp control may be necessary depending on the country. In this case, the PV Plant needs to add an external Plug and Play Storage System.The following figure shows the PV Plant behavior with Plug and Play Storage considering an irradiance perturbation. Considering the control algorithms studied before, PPS allows the system being
Otherwise, the real power control becomes inefficient and the whole system energy production will not meet the optimum point.This type of control is typically demanded in countries with a weak electrical system, as,for example, Puerto Rico. In weak systems, the PV facility needs to be able to respond to any perturbation as long as possible. For that reason,PREPA, the regulatory agency in Puerto Rico,has one of the most restrictive minimum technical requirements. For those cases, GPTech has developed its PPC and PPS specifically to accomplish with weak systems. These solutions can be integrated with any number of devices from different manufacturers and, also, implements the most common communication protocols, what makes them ready for any energy challenge.

which allows for a multitude of string designs. Having 2 MPP trackers, (from blueplanet 3.5 TL1) which can each process the whole AC power, system layout is even easier. Angled roofs or sub-arrays with different orientations? No problem for these flexible appliances. And weighing just 15 kilograms, the blueplanets are almost fun to mount. Using plug-in connectors on the DC and on the AC side, they are also just as quickly connected as they are mounted. The RS485 and the ethernet interfaces, as well as the USB port ensure elegant communication and convenient monitoring. And just to round off the connection, the inverters also have the same integrated data logger and webserver as their 3-phase siblings. As usual, the blueplanet TL1 deliver their full performance without fans. Available as of Q3/2014.
The 3-phase string inverters blueplanet 5.0 – 9.0 TL3 All of the advantages of the larger 3-phase inverters can now be found in one power class which is just perfect for private roof systems. The blueplanet 5.0 TL3 to the 9.0 TL3 come, without exception, with 2 MPP trackers which can get to grips with all imaginable design configurations of a modular PV generator. As such, each MPP tracker can process the whole AC output. If you also consider the extremely wide input voltage range from 200 V to 800 V, multiple string configurations become possible. So, with these characteristics, the blueplanet TL3 present themselves as the most flexible three-phase inverters in their power class on the market. The DC and AC periphery of the blueplanet TL3 ensures the quickest cabling thanks to plug-in connectors and the menu selection is performed conveniently using the graphic display. So that the appliances can stand up to the harshest conditions out in the open, their compact housing is built to IP 65 protection class. Nevertheless, weighing just 30 kg they can still be carried easily. Should the RS485, ethernet and USB port interfaces still leave something to be desired, optional connections for WiFi
and S0-connected appliances as well as 4 digital inlets and outlets are available. The datalogger and the webserver are already integrated as standard! As a result, these inverters offer complete monitoring and strong communication in any environment. Available as of Q4/2014.
The central inverter blueplanet 1000 TL3 outdoor The blueplanet 1000 TL3 outdoor central inverter is the next high power innovation in KACO new energy’s product portfolio. Thanks to its IP54 protection class it does not need to be housed in a separate enclosed room.

The bidirectional battery inverter bluestorage 120 TL3 With the bluestorage 120 TL3 KACO new energy has developed a radically new product with an exceptionally high power rating: 120 kW for charging batteries or feeding into the local grid on 3 phases. This bidirectional battery inverter is perfectly at home with any kind of AC source as well as with all modern battery systems. In so doing, it performs quickly and reliably reaching a rate of efficiency of about 98%. If the grid should fail, you also have the option of using the inverter’s emergency power function. Thanks to its considerable strength, the bluestorage 120 TL3 can transfer large quantities of electricity from peak supply times for use at a later time when demand is higher if the output of the energy source is liable to fluctuate, such as with a gridtie PV system. In view of such features its construction is exceptionally compact. The unparalleled features of the bluestorage TL3 make it the ideal partner for providing decentralised energy from large residential
Used as a key component of a peak shaving system, it lowers the connected load rating, for example – and saves money from the very first day. The bluestorage 120 TL3 also means more flexibility for grid operators too: even in critical local networks, it enables a higher level of PV penetration and affords operators greater planning security. Consolidation of the load and generation profiles also keeps the cost of grid expansion to a minimum.

consists of a diesel and a PV generator with the corresponding mounting system and PV solar inverter as well as the control unit (FuelSave Controller). Even existing generator sets can be adapted to incorporate the FuelSave package so that maximum performance can be achieved. The key to tapping the benefits of a hybrid system lies in the intelligent management of both systems: The centrepiece of the KACO FuelSave is the FuleSave Controller which takes care of this. This controlling system ensures that
the largest possible amount of photovoltaic is incorporated and that the diesel generator is simultaneously deployed in its optimum operating range, at the same time. The KACO FuelSave thus guarantees the maximum PV contribution and minimum fuel costs whilst protecting people and the environment. The configuration without storage system targets maximum efficiency but an optional storage system offers maximum convenience on top and enables diesel operation to be further reduced. Depending on the application, diesel savings amount to 25% or more and the system itself can be amortised in 3 to 5 years. This results in over 200% return on investment (ROI) within 10 years.

Kerala has initiated and installed 10,000 rooftops as part of their 10000 Rooftop Solar Power Plants Programmesimilar to the 1,000 rooftop program in Germany in early 90s. The state of Tamil Nadu has announced a rooftop installation of 350MW by 2015. The state of Andhra Pradesh has already declared their intention of promoting rooftop solar systems through a net-metering scheme. However, there are a number of challenges to the growth of the rooftop PV installations. First, the roof-top installation needs to be carried out according to available space either on residential complexes or on commercial buildings. In most cases these spaces may not be ideal because of various issues like shadowing, soiling due to dust, smoke, bird droppings etc. Secondly, due to thelarge number of Solar PV off-grid plants located in various places, itwould be aherculeantask for utilities/regulatory bodies to monitor energy generation.

igor India Pvt Ltd is a 100% subsidiary of Zigor Corporación S.A from Spain. Zigor is well known for its solar hybrid inverter and power quality equipments globally. The Zigor recently launched its on-grid inverter into the Indian market and these on-grid single phase inverters are very efficient & suitable for Indian temperature conditions. The single phase inverters are IP65 rated and come with 2-MPPT tracking. The single phase on-grid inverter capacity is available in the range of 2kW to 5kW. Zigor India plans to expand into the rooftop on-grid segment along with our already existing hybrid inverter segment in India. no batteries are used and hence the system is more economical and also avoids losses due to storage of power. These solar installations also help in operation of motors to store water in overhead tanks for drinking and toilet use. If any excess power is generated, this additional power is sent back to the grid and the schools get benefited with the net metering (to be installed in the future).
Since this is a grid connected system, this reduces the load on local grid and hence indirectly helps the community with reduced power cuts & grid stability. These projects also benefit students to learn more about renewable energy power and also educate the local community about the latest technologies.
Recently, Zigor India Pvt Ltd has supplied 14 numbers of single phase on-grid inverters for school projects. This installation site is located in southern town in Tamil Nadu. The local municipality has come up with a scheme to implement 3kWp of solar PV technology for fourteen (14) schools in the same town located at various locations. These systems will produce enough energy during school hours to run the school load directly. Since this is an on-grid system

Qualification Testing Of Monolithically Assembled Modules Using Mwt PV Cells And Contacfoil®, A Large Area, Laser Patterned Foil System Markus Rees* and Jörg Ziegler, Eppstein Technologies GmbH, Burgstrasse
contacfoil® is a flexible, laminated foil system, which can be produced in a roll-to-roll-process and which enables the monolithic assembly of modules using back contact PV-cells. The foil system is comprised of a laser patterned conductor layer and an insulation layer (PVB) with laser produced openings to accommodate the cells contacts. It is combined with embedding layers to form the inside of a PV-module to protect and interconnect the cells. In this paper we report on results obtained with reliability tests, namely temperature cycles under load and damp heat exposure according to IEC61215. These tests have been performed with various material combinations and using different technologies for cell contacting. The results show that contacfoil® is a fully functional alternative to flexible circuit boards or string based interconnection methods for back-contact cells offering advantages in module assembly and costs. The foil system can accommodate various module designs as it can be combined with a range of embedding materials and can be used with low temperature solders, conductive epoxies or hybrids alike. The conductor materials and thicknesses (resistance) can be adapted to the specified power rating of the module.
1 OVERV IEW With con t ac foil® EppsteinTechnologies has developed a flexible, laminated foil system, which can be produced in a roll-to-roll-process and which enables the monolithic assembly of modules using back-contact PVcells [1]. The foil system, schematically shown in Fig. 1, is comprised of a laser patterned conductor layer and an insulation layer (PVB) with
laser produced openings to accommodate the cells contacts. It will be combined with embedding layers 1 and 2 to form the inside of a PV module to protect and interconnect the cells thereby adhering to the modules backsheet and the front glass. Module assembly can either be from the front glass or the backsheet side. In both

cases the contacting material (special solder with a low melting point, conductive epoxy or hybrids) is deposited onto the contact points of the cells or onto the conductor at the cells contact positions. In Fig 2 the laser patterned conductor layer with the contact openings is shown together with a MWT-cell prepared for assembly. The solder

bumps on the cell contacts consist of a special solder with a low melting point (typ. 138°C) and are applied by screen printing and can subsequently be pre-cured by heat treatment if needed. In the final lamination process the solder bumps melt, thereby allowing for the formation of electrical contacts between the cells and the conductor layer. Additionally, the embedding and insulation layers become adhesive forming a mechanically stable compound with the backsheet, the cells and the front glass. For studying the module reliability achievable with contacfoil® and these new in-lamination contacting and encapsulation processes, test modules comprising four back contact cells (2x2 as shown in Fig. 3) have been built by using MWT-cells from Solland, different conductors as well as different new and in the meantime commercially available embedding and backsheet materials. These test modules have been exhibited to the most critical reliability tests according to IEC61215, namely damp heat (DHT) and temperature cycling under load (TCT). In order to gain insight into eventual failure mechanisms, the modules performance (IVcurves) has been measured before, at different times during and after the tests. Furthermore infrared and electro luminescence images of the modules obtained before and after the tests have been compared and the load currents of the modules have been monitored during the whole temperature cycle tests. The latter allowed for an exact determination of failure points and failed modules could be taken out of the test for immediate failure analysis. Finally a 60-cell full size module was built and tested for module performance.
2 TEST MODULES AND TESTS 2.1 Test modules A typical 2x2-test-module is shown in Fig. 3. It contains 4 MWT cells of the type Sunweb156PS395, contacfoil® to be tested, a commercially available backsheet (typically Coveme (PYE) or Icosolar (AAA)) and a front glass (typically SGG Albarino T4). For connecting the module to the external tester circuitry contact ribbons have been soldered to the conductor foil and taken out of the module sidewise as can be seen in Fig. 3. Test modules have been built to study the influence of different material combinations on the behaviour of the modules
www.EQMagLive.com
Figure 3: 4-cell (2x2) test-module with external connections (seen at the bottom)
in environmental tests. The results will be used to specify the design freedom for module manufacturers using contacfoil®. The following main material and technology categories have been tested: - Cont acting technology: Low temperature solder, conductive epoxies and hybrids - Conductor materials: Cu in various thicknesses and Al with Cu-coating for cell connection
- Embedding materials: EVA , XUS 66232.00 and a proprietary experimental material An overview over the various material combinations tested and reported here and the environmental test procedures applied is given in Table I. Table I: Overview over tested 2x2 glassfoil modules Of special importance is the selection of the conductor material as the conductor is a major contributor not only to the material costs of contacfoil® but also to the performance of the module. Accordingly copper conductors of different thicknesses have been tested and also aluminium as the preferred low cost conductor alternative was studied. So far the use of aluminium was prohibited in pv-modules due to the lack of suitable contacting technologies. In the tests
Figure 4: Al-conductor with a copper treatment on one side seen through the PVB-insulation layer. Please note the circular contact openings to accommodate the contact material
reported here, we used a 150nm Cu-coating on a 40µm thick Al conductor foil (Fig. 4). The Cu coating provided a suitable surface for solder or conductive epoxy connections between the cells and the Al conductor. 2.2 Tests The various tests have been performed in the laboratories of EppsteinTechnologies as well as of Schott Solar and ECN, the latter in the context of joint development projects. For measuring IV-curves certified PASAN flashers have been used at Schott Solar and ECN whereas the measurements at Eppstein Technologies have been performed with a proprietary LED-based tester. This LED-tester is designed especially for comparative tests with test modules up to 6 cells (3x2) and it is equipped with LED-light engines providing a homogenous illumination, which results in an electrical module solar spectrum according to Air Mass 1.5. The differences of the results obtained by the IV-curves measured with the LED-tester and certified testers are typically < 1%. The thermal cycle test under load (TCT) and the damp heat test (DHT), both as specified in IEC61215, have been selected as the most critical environmental tests. All tested modules have been exhibited at least to one or two times the specified number of cycles and also to one or two times the specified test duration, respectively. Especially the TCT was considered critical as it applies varying stress onto the contact point

and the various material layers due to the
differences in the coefficients of thermal expansion of the various materials used. Hence it was decided to monitor the load currents flowing through the modules during the whole temperature cycle tests. This allowed for an exact determination of failure points and failed modules could be taken out of the test for immediate failure analysis. In Figure 5 typical current traces obtained during a TCT are shown. For selected modules infrared and electro luminescence images of the modules obtained before and after the tests have also been compared.
In Figs. 7, 8 and 10 the degradations of the modules peak power, Pmpp, as measured for soldered modules with Cu-connectors are depicted. Thereby two different Cu qualities have been used, namely rolled Cu without corrosion protection with a thickness of 15µm and electrolytic Cu with corrosion protection with thicknesses of 18µm and 35µm, respectively. In Figs. 7 and 8 the degradations of the module peak power, Pmpp, as measured for soldered modules with Cuconductors are depicted. Good results have been obtained with both Cu qualities (rolled and electrolytic). Also the electroluminescence images show virtually no differences before and after the tests (Fig. 9). In Fig. 8 we notice a certain “annealing” effect and the power output of the modules increases with test duration. The reason for this annealing effect is not yet understood.

Typically good 2x2modules show fill factors (FF) between approx. 74% and 76.5%, depending on the exact material combinations and cell selections used. These fill factors agree well with theoretical calculations and are approximately 0.5% to 1% lower than the values to be expected from full size 60cells modules. This originates from the fact that ohmic losses originating from the cross connections between the cell rows and the connections to the measuring circuit have higher relative contributions to the total ohmic losses in small modules than in large full size modules, where the losses associated with cell connections dominate. A typical IV-curve for a 2x2- module is shown in Fig. 6. By measuring and analysing the IV-curves before after and during the TC- and DH-test, the degradation of modules has been measured using the different material selections.
Figure 9: Typical electroluminescence images before and after test (taken by Schott Solar)
In Fig. 10 the degradation results are shown for 18µm thick electrolytic Cu as a conductor. The trace shows again an “annealing” effect during the first test period and the peak power increases. Thereafter the peak power degrades as expected, but stays well within the limit as specified by IEC61215. Visual inspection of the conductor after the test has revealed small microruptures, which however, do not seem to influence the modules performance below acceptable limits. The root cause for these ruptures is currently under investigation. Figure 10: Power degradation observed for soldered modules with 18µm electrolytic Cu conductor with corrosion protection (measured by Schott Solar) Similar results have been obtained in TC-tests at ECN with test modules using conductive epoxies instead of low temperature solder (see Table I). Finally Cu-coated Al-conductors have also been tested. The results are shown in

The IV-curve measured at ECN with the 60-cells module is depicted in Fig. 14. Analysis of this curve shows that a fill factor of 76.55% could be achieved and the module delivers a peak power of 238.38W under standard test Figure 14: IV-curve measured at ECN 4 conditions (1000W/ m2 and Air Mass 1.5). These data agree well with theoretical calculations and show Photovoltaic Solar Energy Conference and a power loss from cell to module Exhibition, Hamburg, DE, (2011)

CONCLUSIONS
In conclusion it could be demonstrated that contacfoil® is a fully functional alternative to flexible circuit boards or string based interconnection methods for backcontact cells. The foil system supports fully automated module assembly and can accommodate various module designs as it can be combined with a range of embedding materials and can be used with low temperature solders, conductive epoxies and hybrids alike. The conductor materials and thicknesses (resistance) can be adapted to the specified power rating of the module.

We find from many of our Solar Cable user that they find that Rodent or Squirrels are damaging PVC outersheath resulting in short circuiting. APAR has come out with Rodent Proof Solar Cables after lot of R&D and this write up is on our Rodent Proof Solar Cables.
The Solution- Solar Power An infinite source of energy available naturally. Diligent research over the last few decades has yielded sophisticated technology to harness solar energy. The successful use of this technology depends on two critical components, viz the solar panels for generating photovoltaic power & the cables to transmit it. The solar power plant requires cables to -
Transmit from solar panels to invertors -DC Cables

A
s policy initiatives such a JNNSM by govt. of India has opened up the solar power generation sector and accomplishment of more than 2.3GW of solar installations till date under the policy monitoring by MNRE has invited many global and local investors to look towards solar based generation with never before heard enthusiasm. Solar power has a great potential to achieve solar generated electricity to reach towards grid parity with in this decade, but the industry would grow even at a faster rate if costs could be reduced for both the final products and the capital investment required for scale-up. Solar power developers (SPD’S) in India are able to achieve significant cost reduction in capital required to scale up the large solar power generation plant thanks to reduction in global module prices, Inverter prices and reduction in prices of various balance of system component. But once the month on month generation data start trickling in from various project installations when we make a comparision of actual energy yield v/s projected energy yield even for best radiation locations of India has disappointed many solar developers . This difference cannot be not only attributed to lack of design expertise and selection of technology, selection of EPC contractor & various location challenges in installation and commissioning but also largely due to extreme pressure on SPD’s to bring down the capex to achieve cost of generation of solar based electricity to be able to remain profitable viz-a-viz PPA tariffs as a result of reverse bidding process. 48
EQ May 2014
When we review majority of solar installation the natural choice of SPD’s to be advised by project consultants to use FIXED MOUNT STRUCTURES WITH TILT ANGLE AS LATITUDE OF LOCATION to achieve optimum energy yield for the project location. This rationale is quiet agreeable as FIXED MOUNT structures found to be proven track record for good wind stability and low cost and ease of maintenance and also well established vendor base for panel mounting systems and ease of fabrication of FIXED MOUNT structures by local Industries . FIXED MOUNT structures suffer from one disadvantage of low Capacity utilization factor (CUF) commonly used term for solar power plants than the usual Plant Load factor (PLF) used by the power generation industry in India. Capacity Utilisation Factor(CUF) =Energy measured (kWh) / (365*24*installed capacity of the plant).
atmospheric temperature, irradiation, etc. and on the other side is CUF that completely ignores all these factors and also the derating or degradation of the panels. Some more factors that can also be important when comparing PR vs. CUF: -
PR will take into account the availability of the grid, CUF will not.
-
PR will take into account the minimum level of irradiation needed to generate electrical energy, CUF will not.
-
PR will take into account irradiation levels at a given period of time, CUF will not
PR can be used as a tool to compare different solar PV systems with each other – even if they are located at different locations since all environmental factors will be taken into account. Therefore only the design and the ability of the system to convert solar energy into electrical energy will be compared with each other.
In the Indian solar context, PLF (Plant Load Factor ) is perhaps the most used term when it comes to measuring a solar power plant performance. The interesting thing is, not many people outside India understand the CUF because most of them use a much better yardstick such as Performance Ratio(PR).
Since CUF is more accepted by the Indian SPD’s for defining performance guarantees and capacity guarantee we will restrict our scope of investigation as CUF is fundamentally a tool necessary for predicting the energy yield pattern
Performance Ratio (PR) of a plant for a period of time =Energy measured(kWh)/ (Irradiance(kWh/m2) on the panel x Active area of PV module(m2) x PV module efficiency)
The CUF projected for financial closures appears to be slightly higher estimate than the reality as it is evident that even best irradiation location like Rajasthan in India has overcast a achievable average CUF of 19% for FIXED MOUNT SYSTEMS.
So on one side, PR is a measure for the performance of a PV system taking into account environmental factors such as
If we look at ways how to enhance the CUF of upcoming solar power generation

projects one of the possible ways is to look at SUN TRACKER SYSTEMS viz-a-viz FIXED MOUNT SYSTEMS.
Sun Tracked Systems The sun travels through 360 degrees east to west per day, but from the perspective of any fixed location the visible portion is 180 degrees during an average 1/2 day period (more in spring and summer; less, in fall and winter). Local horizon effects reduce this somewhat, making the effective motion about 150 degrees. A solar panel in a fixed orientation between the dawn and sunset extremes will see a motion of 75 degrees to either side, and thus, according to the table above, will lose 75% of the energy in the morning and evening. Rotating the panels to the east and west can help recapture those losses. A tracker rotating in the east-west direction is known as a Single-axis tracker.
The sun also moves through 46 degrees north and south during a year. The same set of panels set at the midpoint between the two local extremes will thus see the sun move 23 degrees on either side, causing losses of 8.3% A tracker that accounts for both the daily and seasonal motions is known as a Dual-axis tracker. There is considerable argument within the industry whether the small difference in yearly collection between single and dual-axis trackers makes the added complexity of a two-axis tracker worthwhile. A recent review of actual production statistics suggested the difference was about 4% in total, which was far less than the added costs of the dual-axis systems. This compares unfavorably with the 24-32% improvement between a fixed-array and single-axis tracker.
of this technology in which single row of fixed mount panels are made to pivot on a single axis in E-W direction with the help of a motor and a tracker controller as per the picture below Horizontal single axis trackers has a advantage of incremental cost additional over fixed mount systems but still suffer from a disadvantage of incremental CUF addition with respect to capex addition as E-W motion alone cannot reduce the irradiance losses and hence CUF addition over Fixed mount systems is marginal. Horizontal single axis sun tracker can initially provide a comfort of small addition in capex to SPDâ&#x20AC;&#x2122;s . Horizontal single axis trackers since placed in rows one behind another compelling to use BACK TRACKING function in controller software to avoid shadow of one row falling on the another row.For a long-term perspective as the life of solar power plant is projected to be 25 years it is prudent to look at achieving higher CUF for incremental capex addition by employing a suitable sun tracked systems. Fr o m t h e Indian context can we have a right balance between increased capex on account of use of SUN TRACKED SYSTEMS to achieve reasonably higher CUF for solar power generation in comparision to FIXED MOUNT SYSTEMS. Jumbo Technologies International Ltd. Hong Kong & Meridian Green energy Pvt. Ltd. India with their design associates in this quest to achieve a right balance between incremental capex addition and significant increase in CUF has looked in to innovative semi automatic dual axis sun tracker solution
of daily automatic tracking in E-W direction and manual seasonal tilt adjustment. Manual adjustment of seasonal tilt does contribute to reduction in CAPEX expenditure coupled with increased CUF on account of dual axis tracking. The array design can have 10 nos of 250W Mono/Poly crystalline silicon solar panels mounted on a tracker frame . and 1MW solar power generation plant require 400 nos of such arrays which will be spread over 6 Acres land area.
INNOVATIVE SUN TRACKER TECHNOLOGY Semi automatic sun trackers combine the advantage of maximum effectives of sun tracking for increasing the energy yield of solar power generation from array and at the same time reducing the cost of sun tracking due to semi automatic function. The semi automatic sun tracker has a daily movement of the sun ( Azimuth angle) managed by a motor driven worm drive mechanism coupled with a seasonal movement of sun (Pitch angle) to be adjusted manually to make use of economical labour avialability. Tracking Mode : To determine the timely corresponding points of the tracking device and sun through the co-ordinated turn of the pitch angle . The different corresponding points during daytime connect together into a tracking curve coinciding with the movement of the sun . The control algorithm employ time control (GPS) .as a major positioning

Fastening Solar Panels To Trapezoidal Sheet Metal Or The Upper Shell Of Insulated Trapezoidal Sheet Metal Roofs Cedrik Zapfe Dr.-Zapfe GmbH, Engineering Office for Construction Engineering and Solar Planning
Summary:When planning solar plants on new or already existing buildings, a structural verification of the connection to the supporting structure of the building is to be created. As the solar sector is getting ever more professional, the connections to the roof have to be checked systematically and the results are transferred into computational models.The fastening to trapezoidal sheet metal or to the covering shell of sandwich elements although complex is very attractive from an economic point of view. Especially for air-conditioned halls, shop floors, insulated sandwich elements are a great solution to reduce the power consumption of the cooling system. Until recently, general rules of technology did not regu-late such applications. The local loadbearing behaviour in the direct surrounding of the local connection with product specific experimental tests is evaluated. Apart from the structural verification of the local connections, a complete structural analysis of the trapezoidal sheet metal or the sandwich element considering individual concentrated loads instead of the typical distributed load resulting from wind and snow is also evaluated. Although it is often possible to replicate these observations when the load transmission distances are smaller and purlin distances are bigger, there are often cases where an individual analysis is required. In such cases, calculations according to the finite elements method or the the calculation methods for stud work constructions deducted from the finite element method are the solutions of choice.

expert companies. This leads to the approach that such installations are regarded as technical building equipment that is subject to rules and standards other than subjects of classical engineering.In the sense of the building law and the building codes of the federal German states, a photovoltaic plant is to be regarded as part of a building or a building itself. As a result of that, the client on whose behalf a solar plant is installed is obliged to adhere to the binding rules of the building code. Apart from the consideration of the local load impacts, verification of structural safety includes the arithmetical verification that the support resistance of the components used is bigger than the load impacts. The verification of usability of building products and types of construction has to be carried out on the basis of the generally accepted rules of technology, for example these include technical standards for steel construction and aluminium construction. If the constructional product under review implies constructional details whose structural verification is not regulated in their accordant technical standards, the product is called a “non-regulated construction product” that must not be used without an approval by the building authorities.
2 Solar fastening systems for roofs with sandwich elements
2.1 Mounting systems The term “mounting system” includes all load-bearing profiles and connection components that are used between the module and the roof covering respectively the supporting roof structure. The direct connection between the mounting system and the roof is created using fasteners. The main task of the mounting system is transmission forces arising at the fastening areas of the module to specific fastening points on the roof and absorbing it into the roof structure. As the module edges and the corrugations of the sheet coincide in only a few places, a mounting system is absolutely essential in most cases. For economic efficiency, a solar plant planner will try to minimize the material that is needed for the mounting system. Figure 1 at the left shows a single-layer mounting system with the mounting profiles run-ning at right angle to the roofing sheet. The vertical orientation of the modules on two load-bearing profiles is often called “portrait mounting”. If the modules are mounted such that the longer side of the modules is perpendicular to corrugations or parallel to the ridge as shown in the figure on the right, this is called “landscape” mounting. Usually, in landscape orientation, the modules are linearly supported on the long side with two modules lying on one mounting rail. Depending on the mounting instructions
www.EQMagLive.com
by the module manufacturer, also other orientations are possible. In case of unframed modules which are usually glass-glass laminates, a cross rail system (figure 2) is recommended in order to avoid problems resulting from the elasticity of the roofing sheet. A cross rail system is made up of two layers of orthogonally arranged load-bearing profiles that are fastened meticulously/precisely to the roof. A decisive advantage of this system is that the mounting system for the PV panels can be adapted individually to the supporting structure. Since the material required in such system is almost twice com-pared to a single layer system, this type of system is rarely installed.

The mounting of such fasteners is rather painstaking and requires a high effort, more time and superior workmanship. Moreover, the position of the fastening points in one direction is determined by the distance of the purlins. This is usually, a material-intensive and costly cross-rail system is required.
2.3 Fastening clamps for the fastening to the crowns of the roof-shell.
Figure 2: Cross rail system
Figure 3: Inclined mounting system
The term trapezoidal clamps or fastening clamps usually stands for form folded highgrade steel parts that fit snugly on the crowns of the trapezoidal sheet metal or the sandwich
Besides roof-parallel solar plants, elevated solar plants are installed as shown in figure 3. In these cases, the modules are inclined using triangular support structures in order to maxi-mize the solar yield per square meter of module area. A shadow distance between the mod-ule rows is maintained to reducing the over-all power generated. The mounting system itself is usually made up of the following components: •
Module clamps
•
Mounting profiles
•
Connection elements

element. These are clamps are fixedto the inclined surfaces of the trapezoidal sheet metal using self-drilling or self-tapping screws. Figure 5 demonstrates two designs by the Schletter GmbH [2] that have to be adapted specifically to the shape of the trapezoidal sheet metal. The mounting rails
2.2 Fastening solutions to the substructure Solar fasteners as shown in figure 4 are an established fastening system for the transmission of the loads directly into the purlin structure. In the process of mounting, a hole is drilled into the horizontalsurface of the crown and a hanger bolt is screwed

are either fastened to the trapezoidal clamp from below with a pair of nuts and bolts (Fix 2000) or alternatively with a clamped connection from above using the Klick top. (Fix2000 KlickTop). For the protection of the coating of the sheet metal, usually a loaddistributing separation layer is inserted.
2.4 Direct fastening of the modules to the upper covering shell So long as there is no specified mounting point but a specified mounting area, precise fastening to the roof cladding without mounting rails is possible. In figure 6, accordant mounting solutions for portrait and landscape mounting are shown. With portrait mounting, a connection between two neighbouring crowns (top flanges) is required in order to be able to adapt the module pattern to the corrugation pattern. Figure 7 shows specific products that are fastened to the trapezoid either to one lateral side or to two lateral sides.

transmission in a sandwich element is a complex load-bearing mechanism that usually is evaluated by experimental tests. In a test series of sandwich elements by 8 different manufacturers [3], the following failure mechanisms (figure 7) could be observed: 1.

Figure 7: Forms of failure with sandwich elements under punctual load In figure 8, a typical load deformation curve of a tensile test is demonstrated. The first phase shows an almost ideal elastic behaviour that is due to the specific loadbearing be-haviour of the trapezoidal clamp. The second phase is characterized by plastic deformations of the trapezoidal clamp. The third, significantly non-linear phase is usually a failure of structural stability of the metal sheet boardings in connection with bearing stress failure of the screws. Only after distinctive ductile deformations, final failure sets in by foam breakage or adhesion breakage. Within the framework of tests for the suitability test, the test body is usually loaded with 5000 stress cycles on service load level, before the static tensile test is carried out to the point of breakage. According to experiences gained so far, the cyclical prestress does not lead to any delamination of the covering layers of the foam.

With the dimensioning of the connection, the structural verifications of the trapezoidal clamps and the drilling screws can be looked up in the general technical approval Z-14.4646 [2]. The structural verification of the sandwich element under a concentrated load should be regulated perspectively in the general technical approval of the respective sand-wich element. Table 1 demonstrates the dimensioning values for the tensile strength and the shear carrying capacity of the sandwich element FischerTHERM according to [4]. The line â&#x20AC;&#x153;2 screwsâ&#x20AC;&#x153; relates to the fastening system SingleFixV. The verification is carried out on the basis of a linear interaction. Further manufacturers of

sandwich elements are currently undergoing suitability tests in order to obtain an upgrading of the general technical ap-proval for precise fastening with trapezoidal clamps [5].

3.3 Overall load-bearing behaviour The overall verification of the trapezoidal sheet metal or the sandwich element is to be carried out according to the the specific technical standards and sets of rules. Here, the limit state of the load-bearing capacity (breakage) as well as the serviceability limit state (SLS) must be observed, with the latter case being decisive in most cases [6]. With most fastening orientations, the grid dimensions of the trapezoidal clamps are consid-erably smaller than the purlin distance. In these cases, the overall verification of the sand-wich element can be carried out in good approximation assuming a distributed load, as the bending moment curve is affine. A specific calculation of the strains only has to be carried out if there is a significant deviation of the bending moment curve under constant load. This can either be done with a frame calculation program, a timber frame model or by means of the finite element method [6], [7].

Solar Mega Power Plants; Challenges in Execution Abhishek Kanneganti, GM Planning, Nuevosol Energy Pvt. Ltd.
A
mongst all the characteristics that can be used to differentiate a developed nation from a developing or an under-developed nation is the notion of “Power Cut”. Power Cuts are the eventual consequences of nations burdened with power deficits. Overcoming the power deficit is a dire need of the hour, and Solar Ultra Mega Power Plants (100 MWs and above) are the best solution possible. This article explores the basic challenges one faces in installing mega power plants, with a special focus on installation of mounting structures.
Mega Power Plants – The Challenge of Land Selection The biggest challenge for a Mega Plant is availability of land. The horizontal area required for the installation of module mounting structures is directly proportional to the output sought. In a traditionally agricultural establishment such as the one that exists in India, and most developing nations, a trade-off of fertile land to provide space for placement of a Solar Plant is an unacceptable proposition. Proven barren lands ought to be the only areas to accommodate a solar plant. However, a majority of such lands put forth newer challenges that include harsh terrain, steep sloping, and varying soil types. Leveling of such lands hikes costs exorbitantly and makes projects unviable.
Following the Contour –Viability, Timelines and Costs Contour following is a novel approach being put forth as a solution by a select few companies that are willing to place structures efficiently tracing the contour of the land while doing so. Contour following is soon going to be a mandatory requirement for every Solar Mega Plant. Developers and EPCs need, however, to be cognizant of the fact that stringent timelines cannot be extended to contour following. Flat, leveled lands are easy to negotiate through; vehicle and human movement is unhindered and hence rapid mobilizations are a rational expectation. Sloped land presents a 56
EQ May 2014
considerable challenge in terms of safety and accessibility to both assets and human beings, thus necessitating an extension in timelines. Leveled lands can hasten timelines without compromising on safety, sloped lands slow down timelines but do not compromise on land area – a trade-off is imminent and the decision is not going to be a simple one.
structures. There is a huge scarcity of the base raw material, as there are very few suppliers for the huge tonnages that we require. Many times there is price escalation and material shortage impacting the timelines of projects. There are random price escalations and material shortages, which form the biggest concern in the industry right now.
Inadequacy of Skilled Workmen; Quality Vs Timelines
Holistic Planning for Execution and Monetary Control.
Lack of skilled labor is another daunting challenge. Solar Power Projects are known to be labor intensive. A vast majority of the contractors operating now are from a civil structures background. The labor employed, however, happens to be vastly unskilled daily-wage earners. . Timelines can be hastened by employing a large number of people and encouraging simultaneous operations. Hastening output, however, from unskilled labor would have a detrimental effect on the overall quality of the product. Most of the solar plants are commissioned to last a full 25 years post-commission, with minor maintenance. Unskilled labor and its propensity for making critical errors, for no other reason than its sheer lack of training and pertinent knowledge, could cause a plethora of issues that would affect both the contingent costs of maintenance as well as the life of a solar plant. Thus, long-term contingencies could far outweigh the shortterm urgency for commissioning a project. Institutes of learning ought to incorporate specific disciplines pertaining to the Solar energy sector to foster growth of affordable and employable individuals to move the sector forward keeping quality intact.
Typical time for construction of Solar PV plants has come down to two months. This calls for simplifying the manufacturing and execution. Planning can be a part of optimization where some highly unexpected bottlenecks can be avoided to ensure timely execution. This calls for thorough understanding of manufacturing bottlenecks and installation hurdles. Planning cannot be decentralized and has to be holistic and in unison with all stakeholders. Planning can avoid Rapid cost escalation, which is usually an eventuality for Mega Plants. Service providing companies start incurring larger costs, costs pertaining to in-site movements of personnel and material. Transportation costs and labor costs, cost previously considered contingent become dominant. The efficiency of product delivery is inversely proportional to the area to be covered, and the only means to tame bottlenecks is by effective planning. All stakeholders need to partake and agree upon a comprehensive plan on paper prior to project mobilization. Excessive delegation and relegation to the service delivery rung would only lead to stalling of work, mainly due to avoidable miscommunications.
Manufacturing Bottlenecks India has to gear up manifold. Steel industry is clearly, not adequately prepared to the supply of raw material, specialized material required for timely delivery for Mega Power plants. The pace at which solar industry is growing requires 2 lakh tonnes of steel supplied to various manufacturing yards only for the purpose of manufacturing solar
Last but not the least, lack of liquidity and pending payments become massive bottlenecks at the lowest rung, these bottlenecks eventually have a domino effect that culminates in project stalling. The banking sector and other financial institutions need to promote better liquidity and allow developers with the leeway to promote percolation down to the project delivery rung.

RAASI GREEN EARTH ENERGY PRIVATE LIMITED EQ : What is the history of your Group CN : Raasi Group is a multi-interest Business Corporation founded in 1978. It is headquartered in Bangalore to leverage on its global reputation as one of the technology centres of the world. Since its founding, Raasi Group has grown from being a Manufacturing House to a diversified and dynamic business group and the company has grown from strength to strength to be recognized as a leading business corporation across the four verticals Manufacturing, IT Services, Insurance and Financial Services and Renewable Energy (Solar)
EQ : Inspiration behind setting up Raasi Solar Park CN : Globally, Energy Security and Climate Security concerns are growing and many countries have realized the need to find solution to both the burgeoning problems in Renewable Energy Resources. India was one of the earliest to realize the potential of the clean, abundant and freely available solar energy and invested in creating an infrastructure to grow this segment. We are now amongst the top solar countries having already installed over 2.5 GW of solar power plants under the JNNSM and state programmes like Gujarat. However considering that our per capita electrical consumption is just about a fifteenth of what the US consumption is, we have to rapidly increase energy generation to catch up with the developed world. Solar energy has a huge role to play in our quest to build a robust economy and to be counted amongst the powerful nations. Realizing the role of solar energy in shaping India’s future, Raasi Group established RGEE with an intention to take part in the solar revolution that is slowly but steadily taking place in India. RGEE recognized very early that while technical expertise in designing and building solar power plants were available in our country, necessary understanding of the complex and multiple policies, regulatory measures and others needed to acquire project sites and get
58
EQ May 2014
all statutory clearances to execute large solar project were lacking. Keeping this in mind RGEE decided to set up a solar park at a place that receives high solar radiation for most part of the year and identified a site in
Ramanathapuram District, Tamilnadu. RGEE is getting all necessary clearances and setting up the necessary infrastructure including power evacuation. RGEE welcomes investors, ESCOs and RE companies to set up power plants upwards of 1MWp in this well connected site.
EQ : Enlighten our readers with your Vision, Mission, etc… CN : Our vision is to be the largest Solar Park Developer in India and one of the top generators of solar power in India by 2020. Our mission is to develop solar parks with all necessary statutory clearances, infrastructure and support services and offer them at competitive prices so that investors are attracted to set up solar plants which would benefit them and the society. We are driven by our core value to achieve our goals through quality and integrity. We are committed to protecting the environment and to follow ethical business practices. We would be partnering with leaders in the field to bring the best technology and practices so as to deliver maximum value to the customer.
EQ : What are the features/ amenities/advantages you provide investors for setting up Solar Plants in your Park? CN : RGEE has been working on the development of the project since 2010. The
600 acre park, located in Paramakkudi Taluk in Ramanathapuram is well connected by road through NH87 and SH 28. The location has on an average, over 300 clear sunny days. The park is being set up as a multi developer, multi technology project with a minimum project size of 100KW. Major statutory clearances have already been obtained. TANGEDCO’s 230/110 kV Sub-Station is located close to the site and a central evacuation facility is being set up in the park. Boundary wall around the park would be provided to enhance safety of the plant. All support required to get statutory clearances for individual power plants would be extended.
EQ : What kind of Investors/ Companies would be attracted to consider investing in Solar Project in your Park? CN : Raasi Green Earth Energy (RGEE) welcomes investors with project allocations under government schemes like JNNSM and those outside of it, investors who want to take advantage of the government incentives for investment in renewable energy, obligated entities and ESCOs. We currently have investors who want to avail ‘Accelerated Depreciation Benefits’ (ADB) under which the investor can claim depreciation up to 80% in the first year. Also we are housing those who are bound by the Tamil Nadu government’s ‘solar purchase obligation’ and those who are bound by Central government’s ‘Renewable Energy Purchase Obligation’. Companies wanting to reduce their carbon foot print and those
www.EQMagLive.com
corporations who would like to contribute to the transition to sustainable technologies are also welcome to invest. Raasi 100 MW solar park has been developed to house projects under all schemes.
EQ : Kindly share the Solar Resource Assessment Study of your Park. CN : The park is located in Kavanoor in Ramanathapuram district in southern Tamilnadu with the co-ordinates: 9°29’20.20”N, 78°33’11.51”E. It has over 300 clear sunny days and receives an average radiation of 5.48 kWh/m2/ day (Meteonorm). Estimated power generation is 1.6 Million units per MW per year.
EQ : What are the challenges an investor faces while setting up solar plant independently CN : Solar Energy is no longer a foot note in the overall energy planning of the country. Obligated entities, companies wanting to reduce carbon foot print and others seeking investment opportunities all see investment in solar projects attractive However investors are aware of the hurdles involved in establishing a solar power plant with the main one being ‘land acquisition’. Identifying large tracts of non-productive land for setting up power plant with reasonable infrastructure and acquiring it without hassle is really a challenge in today’s world. RGEE, at present, has 600 acres of land earmarked for this park. The other major hurdle faced relates to the ‘evacuation facilities’ for the generated power. Cost of establishing a power plant runs into crores of rupees and when the generated power is not evacuated daily, it would lead to huge loss. RGEE has established evacuation facility at its own cost and this should not be a concern for the developers. All issues that could potentially hinder the execution of the project are all taken care by RGEE and the investors with out any hesitation can invest in the developed solar park and execute the project at the shortest possible time. Operations and maintenance of the plant again could be a major concern for the developers if a dedicated team is not set up. RGEE will provide O&M services on 24 x 7 basis with their own expert team.
EQ : What are the various options/
www.EQMagLive.com
packages/inclusions you offer to investors? CN : We are offering four options as explained below: a. Own Plant, Own EPC & Own Funds – In this option, the investor comes to us with their chosen EPC partner, their own finances and we will be happy to facilitate land, plant design, permits and evacuation of the power solar plant to the developer. The plant could be set up in a very short time. b. Own Plant, Own Funds, & RGEE EPC- In this option, the investor comes to us with his own funds to set up solar power plant meeting his requirements. We provide land, design, permits and evacuation facilities and also assist the solar plant developer with our EPC partner. c. Own Plant, Own EPC & RGEE assisted Funds- Setting up a solar power plant requires high initial investment and to get financing, several conditions are to be met. It would take months of efforts to get funding. To such of those investors who do not want to go through the rigour that is demanded for getting financing, RGEE extends support to investors to get funding at reasonable cost. We have tied up with a couple of reputed non-banking financial institutions who will be happy to assist solar plant developer in raising funds; under their terms & conditions. Also, this offer is limited to only those developers who are ready to be a part of RGEE Solar Park. d. Own Plant, RGEE assisted EPC & Funds- Solar plant developer wants to own plant but without any hassles attached to it. RGEE has tied up with a company who will come in with their EPC services and invest up to 70%. By choosing this option, solar plant developer will not lose ownership, equity nor will solar plant developer lose his discretion regarding design, specification or technology. Developers are free to negotiate solar plant developer terms and conditions with their chosen vendors. Again, this option is available to only those developers who will be setting up their plant in RGEE Solar Park.
EQ : Kindly enlighten our readers on the various policy initiatives by government under which solar plants could be set up in you park CN : Any commercial entity can set up park with us. Till date we have had queries from both independent companies and groups
of small companies that are desirous of forming a collective to purchase power in a big way. Investors with interest in getting long term returns have approached us for setting up plants under various the following schemes: • Tender
Projects under Tamil Nadu
• JNNSM both Phase I and Phase II projects. • REC Projects, (Group Captive/ APPC/Third Party) • Accelerated Depreciation Based Projects.
EQ : Have you installed a pilot project etc… to demonstrate the Performance, Generation etc… CN : A test bed of 100KW is already under execution and another 30MW project will be soon set up for one of our clients. We have received Expression of Interest for projects totalling over 260 MW under various schemes.
EQ : Kindly share your opinion on the Tamil Nadu Solar Policy, Market, Policy & Regulatory aspects hindering the growth of Solar in TN. CN : Tamil Nadu Policy when it was announced in 2012 created excitement that was next only to the excitement the JNNSM announcement generated. With a target of 3 GW to be installed over three years with Solar Purchase obligation of 6%, it appeared that Tamil Nadu would be the next growth engine for solar. However the differing rates fixed by TANGEDCO and TNERC came as a big set back. Petition challenging the solar purchase obligation in the appellate tribunal and TNERC’s handicap with out being fully constituted resulted in the holding up of the ambitious TN Solar roll out. RGEE is providing all back ground material and suggestions to authorities and leading the efforts to the successful implementation of the TN solar programme under existing TANGEDCO tender and the revised 2% RE obligation. RGEE is committed to contribute to the success story of solar not only in Tamilnadu but in the country as a whole.

Renewable Energy Financing in India: Challenges and Solutions Chirag Mehta - Director, Clip Financial
E
nergy is amongst the most important levers of economic growth and absolutely vital to the sustenance of a modern economy.India, however, faces formidable challenges in meeting its energy needs and providing adequate energy of desired quality in various forms to users in a substantial manner and at reasonable cost. With a production of 1,006 TWh, India is the fifth largest producer and consumer of electricity in the world. Inspite of this, according to the World Bank, roughly 40 percent of residences in India are without electricity. The economic impact of power cuts is crippling. Shortage in power supply has resulted in industries across the country being asked to slow down their manufacturing or even shut factories for a certain number of days in a month. The fear of regular electricity cuts is forcing many businesses to install their own power generation or power back-up units. That is not only increasing their capital costs, but also adding to their operational expenses. Electricity generated by these units is up to 100% more expensive than that supplied by the regular grid.This is because the majority of these back-up units generate electricity using diesel, which is more expensive than power generated from coal. It is difficult for the industry to operate on generators for long hours as profit margins dip drastically To give an example of the economic impact of power shortage let’s look at the case of the industrial hub of Tirupur. According to a media reports, Tirupur exports knitwear worth Rs 13,500 crore per year which is expected to fall to the extent of Rs 5000 Cr if the power crisis continues for long. Tirupur faces power outage that lasts for more than 10 hours per day. The government targets capacity addition of 88.5 GW under the 12th Five-Year Plan (2012–17) and around 100 GW under the 13th Five-Year Plan (2017–22). Investments of around

USD223.9 billion are planned for the power sector during the 12th Plan FiveYear Plan to bridge this gap. The total demand for electricity however continues to rise and though some large scale power it requires a significant initial CAPEX, followed by minimum variable ongoing cost. Hence successful commissioning of renewable projects depends heavily on adequate financing of the projects.
projects have been commissioned the demand far outstrips the supply.
Case for Renewable energy India currently meets its power requirements by primarily using conventional resources with renewable sources adding to only 12 % of total power.
What is stopping the rapid growth of Renewable Energy? There are multiple challenges the industry is grappling with. The reason why renewable energy is not an automatic choice and has to depend on government subsidies is the high cost of power as compared to conventional sources.Secondly, the challenge in a Renewable energy power project is that
The cost of producing a unit of electricity has been coming down rapidly. In the case of Solar the cost of PV modules, which is the most significant cost has shrunk dramatically over the years.But the problems related to financing solar projects persists.
Challenge of finding adequate financing A variety of investors finance renewable energy projects in India. These include institutions, banks, and Equity investors.
1. Banks have slowed financing Access to debt has become difficult now and is likely to become even more difficult in the longer term for several reasons: •
Banks have sector limits to limit their exposure to any one market, sector, or technology. As renewable deployment increases, more banks are nearing their sector exposure limits.
•
Further, most banks in India include renewable energy in their power, utility, or energy sector limits. These sectors have heavy borrowing demand, to the point that many banks may have been near their limits even before lending to renewable energy could begin. • While many banks have sector limits, others will not lend to the renewable energy sector at all due to the novelty of the sector, immature technology, and uncertain regulation. • Banks cite non-familiarity with the renewable energy sector as well as the

perceived riskiness as the major reason for not lending to renew¬able energy projects. Even among banks that lend to these projects, the amount is restricted due the reasons discussed below. .
2. Development Finance Institute have limited funding ability The Development finance institute (DFI) in the renewables space is Indian Renewable Development Agency (IREDA). IREDA, the investment arm of the Ministry of New and Renewable Energy (MNRE) is a government agency that offers loans to renewable energy projects at favorable rates compared to commercial lending. However, the scale of IREDA is small compared to the challenge of financing Indian renewable energy ambitions. Other DFIs like SIDBI etc. have specialized schemes but they address much smaller section of the ecosystem.
3. State Level Issues One of the bigger challenges this industry is facing is working with the State electricity boards (SEBs). Banks are concerned about the financial health of the SEBs as they typically act as counterparties to most PPAs signed by renewable energy developers. In fact there are several states where it has become harder to get loans due to the risk associated with the poor finances of the SEBs. Also the limited availability of evacuation infrastructure and grid interconnections is a big state level obstacle to harnessing renewable energy potential. Many economically attractive renewable projects are suffering because of lack of adequate grid evacuation capacity and approach roads.
4. Cost of CERs have fallen substantially Sale of Carbon credits generated from renewable energy projects was an additional revenue stream for these projects. However the selling rate of CR has fallen substantially in the market owing to a supply demand mismatch. This is another factor that has
www.EQMagLive.com
further impacted the revenue generation capability of these projects making debt financing difficult. Than how to raise capital for these projects?
1. Balance Sheet funding Financial institutes are more comfortable providing balance sheet funding. In this case the risk of the project is spread over the entire balance sheet (i.e. other allied businesses) of the developer. This gives banks the recourse to the parent company of the project developer. Developers can extract a signifi¬cant premium for balance sheet debt at the parent company level over project debt, because of the lower risk to the parent. Project level funding get approved mostly if it is backed by a reputed promoter who is ready to give a guarantee. Moreover this is more suited for small MW size projects where the end goal for the promoter is investment and not generation of power. Hence, marginal projects from smaller, unconnected developers find it more difficult to raise capital.
2. PE/VC Despite a lull in private equity investment in infrastructure, interest in renewable energy remains high. At least half-a-dozen international financial investors and a score of PE funds, are scouting for asset-level deals. Apart from financial investors, international firms are also looking at strategic investments in India, while domestic companies are considering options like mergers to achieve critical scale. However, international strategic investors are unlikely to acquire 100% stake in Indian portfolios as they are wary of the risks of land acquisition, permits and construction in India. Hence the trend is for investors and developers to acquire majority or controlling stake in projects especially with sound PPAs. The renewable power space saw 32 private equity (PE) and merger and acquisition (M&A) deals worth $1,288 million in 2013 against 14 deals worth $298 million in 2014 so far.
3. External Commercial Borrowings (ECBs) Sourcing debt from foreign lenders especially from the EXIM banks of the countries from where the equipment (for
the renewable project) is being procured has become quite popular. This is a very effective way of financing as the rate of interest for a foreign currency loan is significantly lower than Interest rates prevalent in India on term loans. However with currency fluctuation and high cost of hedging ECB market has dried up to a large extent.
4. DFIs like IREDA and SIDBI SIDBI has schemes like JICA-SIDBI Financing Scheme, KfW-SIDBI Financing Scheme and the Sustainable finance Scheme (SFS)through which they provide loans to:
1. MSMEs planning to invest in : •
Energy saving investments in plant and machinery / production processes in order to reduce carbon footprint and enhance Profitability.
•
Cleaner Production and emission reduction measures, waste management and Common Effluent Treatment Plant (CETP) facilities.
2.
Energy Service Companies (ESCOs) providing solutions for renewable energy
3.
Original Equipment Manufacturers (OEMs) which manufacture energy efficient / cleaner production / green machinery / equipment for MSMEs
5.
Panel Financing
Select EPC providers have back end panel financing arrangement with EXIM banks or financial institutes. They help arrange panel financing which is amongst the most significant cost in a solar project at attractive sub 10 % levels. However the catch obviously is that they expect the developer to award them the EPC contract. To summarize, financing renewable projects is difficult but not impossible. What’s required is the right strategy and the knowledge to approach the relevant financial institute. Additionally many government incentives and subsidies are available that cushion the cost of setting up a renewable project. India currently offers incentives like feed in tariffs; generation based incentives; renewable purchase obligations (RPOs); central, state, and regional capital subsidies; accelerated depreciation; and tax incentives. A judicious approach would definitely see the developer being successful in the medium to long term.

Guernsey – Financial Services For Cleantech Projects
G
uernsey is an island situated between the United Kingdom and France which is seeking to harness some of the strongest tides and winds in Europe to provide tidal power and offshore wind production. However, the island is also a leading international finance centre and as such, it can provide a wide variety of financial services solutions to cleantech projects not just in Guernsey but around the world, including those in India.
heritage in providing financial services to clients around the world. This experience has helped a finance industry with significant depth and breadth through four key pillars: •
31 licensed banks, ranging from leading international banking groups to boutique private banks, holding US$138 billion of deposits.
•
150 licensed providers of wealth management services for high net worth individuals and families.
•
50 investment fund managers, administrators and custodians servicing more than 800 Guernsey domiciled funds and assets valued at nearly half a trillion US Dollars.
•
20 international insurance managers providing a range of risk management solutions, including captive insurance – the Island is the largest captive insurance domicile in Europe and fourth in the world.
The island Guernsey is a British Crown Dependency, which means that it is independently governed and this offers political and economic stability. The Island is situated within Europe geographically but it is not part of the European Union (EU) where there is a special relationship. Its location means that it is in close proximity to both the London and other main European markets and in a time zone where business can be conducted with India and the Americas during the same working day. Guernsey also offers the comfort of being English speaking and using the British pound Sterling.
The international finance centre Guernsey has more than 50 years’
62
EQ May 2014
It is this infrastructure and expertise which means that Guernsey is ideally placed to provide financial services for each stage of the cleantech lifecycle.
Investment funds Guernsey is one of the major global investment fund domiciles andas such, is an ideal option for investing in existing cleantech projects or for a new cleantech venture seeking finance.
The island has a thriving investment fund and private equity industry and Guernsey domiciled and administered funds hold investments in a wide range of cleantech assets including wind, solar, wave and forestry as well as in technology which seeks to reduce the impact on the environment in the form of emissions and waste. Guernsey’s regulator has significant experience of understanding investment fund structures and with the island being outside the EU, it is able to provide a flexible and proportionate regulatory regime. In addition, Guernsey is tax neutral for investment funds which means that tax is only paid by investors in their home country. Many major investors are familiar with the island and some of the cleantechindustry’s biggest investment houses have Guernsey domiciled clean energy funds. An example of a Guernsey fund with a focus on clean technologies is the Indian focused Mytrah Energy Limited (see box). Guernsey has an advantage as a domicile for cleantech as it can demonstrate substance already present in existing structures. A number of major fund managers have offices and staff present in the island and there is a large pool of qualified non-executive directors, many with broad industry experience and specific energy and cleantech experience. The desired fund structure for any cleantech project will often be dictated by the requirements of investors, but consideration
www.EQMagLive.com
should also be given to whether the structure will remain optimal as the project proceeds and, indeed, the most appropriate exit strategy should be established at the outset of the venture.
Project finance Guernsey can provide a variety of potential sources of project finance. More than 30 international banks operate in Guernsey plus there is a wide community of wealth managers who undertake to meet their clients’ demands for suitable investment opportunities that have an environmentally friendly remit. Securitisation vehicles are a popular way to finance cleantech projects and Guernsey vehicles have long been used to provide much needed finance within structures for startup capital as well as for on-going capital requirements. Guernsey securitisation vehicles are legally robust, tax efficient and can be established and operated in an efficient way. Also, the ability to float companies on international exchanges may prove beneficial to a cleantech fund since a stock market launch may provide early investors with an exit route from the project as well as provide access to further capital investment. Guernsey companies can list on the London Stock Exchange (LSE), Euronext, Hong Kong, Toronto, Australia as well as the local Channel Islands Securities Exchange (CISE), amongst others. A number of Guernsey cleantech vehicles have been utilised to access various stock exchanges and most notably the LSE where data shows that there are more Guernsey entities listed on its three markets than there are vehicles from any other non-UK jurisdiction.
Therefore, it is important that any cleantech team understands the risks that will arise during a project’s lifecycle. However, the traditional insurance market largely operates by rating risks according to past experience but cleantech projects are, by their very nature, new and speculative ventures, often run by pioneering entrepreneurs. This means that the traditional market underwriters will rate conservatively and potentially charge a greater premium than the actual risk might warrant. Premiums charged by the traditional markets are also subject to market forces, and the loss of a similar, perhaps competing, project often leads to increases in premium. This increases the appeal of captive insurance, where Guernsey has specific expertise, and is ranked first in Europe and fourth in the world. A captive insurance entity is a vehicle owned by the cleantech project, which would write and retain some, or all, of the risks arising from the project. It provides an innovative solution for new risks that are not readily insurable or are prohibitively expensive to insure on the open market. The use of a captive insurance company can help to reduce the overall insurance spend and bring greater certainty to the insurance budgeting process.
Intellectual property (IP) protection
Recent listings by Guernsey funds on the LSE include the Bluefield Solar Income Fund and The Renewables Infrastructure Group (TRIG), with the latter fund raising over US$500 million on its floatation, which Bloombergreported at the time as the largest clean energy IPO in London.
The key IP rights relevant to cleantech typically include patents and confidential know-how for the protection of inventions, design rights for products, copyright and database rights for the protection of software and information systems and also trade marks for the protection of brands. Guernsey law recognises and gives protection to the full range of IP rights through a suite of legislation primarily based on UK and EU laws and models designed to be compliant with the World Trade Organisation’s Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS).
Insurance and managing project risk As with any start up project, insurance will be a key requirement for a successful cleantechproject. Without access to reliable and cost efficient insurance cover, it can be hard to secure the third party funding to develop an idea through to a finished product.
Guernsey also has common laws of confidentiality and passing off and there are proposals for the introduction of utility models (or petty patents), which are easier to obtain than patents. Furthermore, Guernsey has the flexibility to quickly adapt its IP laws to meet changing market requirements
www.EQMagLive.com
through a shortened legislative procedure for IP laws. Guernsey also has the advantage of not being bound by EU requirements, enabling it to pick and choose the most advantageous combination of legal protection for IP rights. Against this backdrop of a solid and innovative IP regime, the key advantage that Guernsey has to offer is as a jurisdiction in which to hold or license both Guernsey and non-Guernsey IP rights. As well as using a standard Guernsey company as an IP holding company, Guernsey offers the option of using its innovative cell company structures where different bundles of IP rights can be held in different cells of the same company.
Why Guernsey? In conclusion, we can see that Guernsey offers an environment which allows for the provision of financial services solutions to meet the needs of cleantech projects during the different stages of their lifecycles. The Island is able to differentiate itself from the competition by the fact that it has such a broad offering but also one with significant substance. In addition, Guernsey’s robust yet pragmatic regulation provides security but also allows innovation and its tax neutral status offers fiscal advantages alongside a regime which respects client confidentiality but also meets international standards of transparency and exchange of information. Furthermore, the quality of service obtained is a real differentiator in Guernsey’s favour as compared to its competitor jurisdictions.

G
ovt. of India almost abruptly discontinued accelerated depreciation for wind energy sector w.e.f. 1 April 2012. The reactions started coming in from all across where in almost all industry experts were found contesting to be louder to showcase the demise of the wind sector post AD withdrawal, which actually is not the fact. Although the installation numbers an year after this event fell down from 3196 MW to 1700 MW, this drop of about 46% made everyone to think in straight line and blame withdrawal of AD as obvious reason which in not the fact.
always been linked to general industrial growth & GDP in country as well as interest rates. *Source: Public web sites, Average approximate numbers taken A close observation of above graph clearly indicates that when GDP peaked at 8.5-9% in 2011-12 the wind installation also peaked at 3196 MW and during that year the average PLR was relatively very low (below 12%) in comparison to other preceding or forthcoming years.
Incidentally, in USA production Tax credit (PTC) is key driver for the wind project & AD benefit in India was introduced almost in same line (in different format) to promote renewable energy. When in USA with expiry of PTC the installation almost dried by 90%, in India the impact was not so intense when AD was withdrawn.
Some factors which affected the general fall in number are as follows: 1. Withdrawal of Generation based incentive: Along with AD the benefit of GBI was also discontinued. This was simply direct cash benefit to investor linked to the generation.
2. Policy issues: Incidentally, post March 2012 some states which has potential for wind installation, some or the other issues in the policy & regulation which created hindrance for development, e.g. Gujarat policy was expired during that time, New wind tariff of MP was to be declared, PPAs were not getting signed in Maharashtra, Captive use of power was not being permitted in Rajasthan, Andhra Pradesh Policy was delayed.
3. General Slowdown: History suggests, with our without depreciation the wind development has 64

Reduction in GDP & increment in landing rates have adversely affected installation in last 1-2 years.
Hype about REC market failure Collapse of the REC market was the buzz word in last 2 years. There is no doubt about it that REC market was not as successful as it was anticipated but actually it was not meant for such ‘desired’ success. Putting a Solar project at Rs. 7 Cr. / MW, selling power to third parties at Rs. 5 / unit plus getting REC revenue of Rs. 9.6 / unit and finally enjoying AD benefit on the project is something which is absolutely impractical. Above numbers if achieved can give IIR as high as 50% which can never be long term story. Actually, 31% of Solar REC & 41% of Non Solar REC issued in FY 12-13 are sold. But % clearance looks very low as there is inventory lying for previous years.
Commercially, it was not poor proposition for investors. However the real worry of investors is uncertain future which is a genuine threat. It’s high time for Govt. & regulators to rationalize the REC floor prices and make them realistic which would help in higher clearance of volume. Investors revenue (due to increase in volume) even after drastic price cut would not be affected on the contrary it should bring in stability in the market and eventually confidence of investors as well as lenders. It would be very illogical to conclude that REC story is over. Infact there is other side of this story which indicates a bounce back & even broader coverage in coming years which will be supported by increment in utility tariff (& eventually higher realization) and conclusive development in the enforcement of REC by various Regulators Growth in Captive Market: In last 5 years share of captive/Group captive wind energy installation as % of total installation is almost doubled. By tying up wind power for captive purpose the power cost of the factory / Production is frozen for 20 years. For instance, In Tamil Nadu MP & Gujarat the in 2007-08 the industrial tariff were in the range of Rs.3.3-3.5/unit. Today it is Rs. 5.5-6/unit, this tariff coupled with ‘little’ clearance of RECs makes viable sense for investor to add capacity.
Conclusion: There is no reason that India will not able to touch the 15000 MW targets of current 5 years plan. Delay in reinstating AD in wind sector can affect only to limited extent and REC market will continue to bear fruit for investor.

Panasonic Corporation
P
anasonic Corporation today announced that it has achieved a conversion efficiency of 25.6% (cell area: 143.7 cm²) in its HIT® solar cells, a major increase over the previous world record for crystalline silicon-based solar cells. The previous record for the conversion efficiency of crystalline silicon-based solar cells of a practical size (100 cm² and over) was 24.7%, as announced by Panasonic in February 2013 (cell area: 101.8 cm²). The new record is 0.9 points higher and the first to break through the 25% barrier for practical size cells. This new record is also an improvement of 0.6 points over the previous record for small area crystalline silicon-based solar cells (cell area: 4 cm²) of 25.0%. The achievement of this new record was made possible by further development of Panasonic’s proprietary heterojunction technology to realize the high conversion efficiency and superior high temperature properties of the company’s HIT solar cells as well as adopting a back-contact solar cell structure, with the electrodes on the back of the solar cell, which allows the more efficient utilization of sunlight.
to realize a high temperature coefficient of -0.25% per degree Celsius which is able to maintain a high conversion efficiency even with high open circuit voltage (Voc) and at high temperatures.
2. Reduction in optical loss In order to increase the current in a solar cell, it is necessary to lead the sunlight which arrive at the cell’s surface to the monocrystalline silicon substrate, which is the layer which generates the power with less loss. Placing the electrodes on the reverse as back contacts allows the light to reach the substrate more efficiently. This has led to a marked improvement in short circuit current density (Jsc) to 41.8mA/cm² over Panasonic’s previous figure of 39.5mA/ cm² (in the case of a cell with a conversion efficiency of 24.7%).
3. Minimizing resistance loss
current is accumulated in the surface grid electrodes and output externally. Previously, the grid electrodes on the light-receiving side were optimized by balancing the thickness of the grid electrodes (thinning the grid electrodes to reduce the amount of light blocked) and the reduction of electrical resistance loss, but by placing the electrodes on the reverse side, it has become possible to reduce the resistive loss when the current is fed to the grid electrodes. In addition, a high fill factor (FF) of 0.827, has been achieved, even at a practical cell size by improving resistance loss in the amorphous silicon layer. Going forward, Panasonic will continue to pursue technology development of its HIT solar cells, aimed at realizing higher efficiency, lower costs and the more efficient use of resources, and will work towards mass production.
In solar cells, the generated electrical
Outline of the core technologies behind the record conversion efficiency 1. Reduction in recombination loss A key feature of HIT technology is its ability to reduce the recombination loss of charge carriers, particles of electricity generated by light, through laminating layers of high-quality amorphous silicon on the surface of the monocrystalline silicon substrate, where power is generated.

Smart Metering- Powering Energy Conservation Through M2M Technologies M2M Technologies
E
nergy conservation and ecofriendliness has taken centre stage in the world around, even as the energy resources are depleting day by day. Add to that the environmental concerns of global warming and increasing green house gases, the problem seems ever increasing in nature. Nations and corporations across the globe have energy conservation high on their social and economic agendas. They are trying out various ways and means to conserve energy and produce clean energy. While clean energy seems to be a natural option, it will take many years before they become mainstream and find unequivocal adoption. But the fact is that there is too much ambiguity and far too much cost involved to economically sustain alternative energy sources as the prime source of energy. However, even with alternative energy coming into play, the key to energy security and a cleaner environment is conservation of energy. But most importantly, it is about the most efficient and optimal usage of energy which surpasses every other concern that we may have. The main reason behind is that the alternative energy today is considered to be a costlier alternative to conventional energy sources albeit with significant long term economic and environmental benefits. And if the power generated by alternative sources is not consumed in an accounted manner, the cost of funding such projects will grow manifold making alternative sources of power a distance reality. With the recent release of Smart Grid Roadmap of India, by Ministry of Power, Govt. of India, the Energy market in India is poised to grow at an exponential rate over the next couple of years with a good mix of M2M connectivity technologies that are available from Telit. Besides that, the government has also decided to dole out tariff subsidies for consumers reducing the burden on utilities and making alternative power affordable for consumption. However, in spite 66

of these efforts one of the key concerns that the government has in mind is the issue of optimal energy usage without any wastage or unaudited usage of energy.
level of power distribution transformers and feeder lines to measure the energy fed and billed back by the utilities that in turn helps monitor & minimize the T&D losses.
One of the key aspects that will make the governmentâ&#x20AC;&#x2122;s plan to provide power grid based areas and off grid areas with nonconventional sources of energy is proper accounting/ auditing of the power being consumed. Amongst the primary reasons are pilferage and wastage of energy due to theft and technical power losses. Even if the government provides power to offgrid areas with non-conventional sources of energy, the key concern of the government would be to ensure that power usage is fairly balanced between power generation costs and revenues. If it is unable to check this aspect most of the projects envisaged by the government may start to seem untenable.
One of the key technologies that is helping drive this conservation initiatives across the globe is adoption of smart metering concepts that are being powered by M2M (Machine-to-Machine) technologies.Telit is also participating in the upcoming Smart Grid & Smart Metering initiatives by the Govt. of India. Leveraging our core M2M expertise and wide product portfolio of 2G, 3G, LTE, CDMA & Short Range modules, Telit is able to offer an end-to-end solution for the entire connectivity needs of the utilities.
Same holds true for the conventional sources of energy. Today, only about 60% of the power generated by the country reaches the consumer. Nearly 40% of the power generated is lost due to inefficient transmission technologies and theft. If the scenario remains unchanged with alternative sources of energy kicking in, the scenario would not be any more different. Apart from these aspects, there is also a lack of understanding and awareness amongst consumers in terms of efficient usage of the power that reaches their homes further adding to the woes of energy conservation. Though Transmission & Distribution (T&D) losses are not unique to India, it has global precedence as well, the key aspect besides creating awareness amongst consumers on efficient usage of power is that technological interventions need to be put in place to alleviate these issues to a great extent. Telit has been actively participating in the govt. driven R-APDRP program wherein we have successfully deployed thousands of M2M modules in field by the way of AMR modems through our OEM/ODM partners.

M2M technologies are not only helping utilities become economically more viable but are also making consumers aware of conservation techniques that could help bring down their energy costs. While consumers also benefit from the adoption of such technologies, the utilities benefit the most by getting access to data and information that was otherwise not possible. Adoption of smart metering technologies powered by M2M technologies not only provides them with almost real time data and information but also provides significant visibility into their energy auditing process, helping them account for almost every ounce of energy consumed. This not only helps them monitor the usage patterns but also provides them with insights into terms of power usage and helps them narrow down to problem areas (irrespective of whether they are technical issues or pilferage issues). Normally standalone metering (which is largely the standard right now) is highly person dependant which can result in a great

deal of human errors that make accurate measurement of power consumption almost impossible. Besides that there are many related issues that come into play when we have archaic metering systems. Energy audits which are performed based on bill collection are highly inaccurate as billing is done on an estimated monthly average consumption basis. Due to this utilities are unable to monitor and control discrete loads leading to lack of consistent supply thereby resulting in frequent outages. Manual reading of meters increases billing cycles apart from introducing inaccuracies in the data that does not help in making critical analysis such as demand analysis, energy audit and pinpointing losses. But introduction of innovative concepts like smart metering or wireless AMRs (Automated Meter Reading) technologies will help alleviate such issues. This is because wireless AMRs and smart metering concepts will help utilities move towards a more centralized operational control model wherein data communication starts to play a more pivotal role in the overall operation
of utilities’ electric distribution systems. Everyday more and more utilities across the world are turning to wireless technologies to improve operations and decision making in the delivery of various customer services including electric, gas, water, etc. As this reliance on wireless connectivity grows and technology improves, wireless networks start taking an increasingly significant role as the backbone over which utilities are connected to their assets, employees and customers. The impact of M2M technologies is not just restricted to benefiting utilities but it also has the potential to impact the behavior of consumers towards energy conservation. With the help of M2M technologies they can get an accurate view on how each energy consuming device in their household is contributing to their energy bills. For demonstration purposes, let us say, if a consumer gets visibility into which device consumes the greatest amount of energy under what conditions, he/ she would be more careful in operating that particular device resulting in reduced energy bills in
the long run. This can be made possible by using different kinds of sensors which are connected to M2M devices/ applications that provide them with wireless updates about their energy consumption patterns helping them make more informed decisions on their usage patterns. Besides this, it will also provide them with visibility into when and how are they consuming more power than the sanctioned loads thereby helping them optimally use the energy. This will not only lead to lower energy bills for consumers but will also help them conserve energy. While there are numerous other benefits that M2M enabled smart metering concepts can bring to the table, what is very clear is that they play a critical role in the world’s effort towards energy conservation and reducing the carbon footprint due to inefficient usage of power and electricity.

ven after 11 years of the effect of The Electricity Act 2003, Open Access is still a distant dream for many stakeholders of the sector. Reasons may be transmission bottlenecks or political will, the end result is the same. Though bulk consumers trade around 40% of the power traded through leading power exchanges to procure power by-passing the local utilities, serious issues in Open Access still remain. Indian GDP is stalled by 0.4% because of power cuts to the industries as per FICCI and the loss of markets because of higher prices, which is the key resultant of higher power procurement cost, is still not found in books of India Inc. A 100% Open Access implementation throughout India by empowering the infrastructure, consumer and local utility is very much important in the scenario to minimize this loss. More than the governmentâ&#x20AC;&#x2122;s will, it is the lack of Infrastructure and the lack of information for the bulk consumers in performing the cost benefit analysis in the respective states of their businesses, which
68
EQ May 2014
is the reason for very few consumers availing Open Access even in the states which are permitting the Open Access to the fullest. This year after elections, there will be a positive scenario in the Indian markets providing lots of opportunities for the industries to grow globally by imparting the competitiveness in prices by minimizing the cost of power procurement. This report focuses on providing information on costs and benefits which can incur to the consumers by opting Open Access and will actually pave a way to empower the bulk consumers in the state to get the idea on how Open Access in Electricity is going to be a boon for their businesses.
INTRA-STATE OPEN ACCESS Rajasthan is one of the most favorable state for intra state Open access. Being a hub for electricity intensive industries like Textiles, Granite and Chemicals, the need for reliable and economic power is very
prominent. Rajasthan is among the leading investment destinations in India. Hundreds of Industries are expected to come up in IT and Manufacturing fields in Mahindra World City, Jaipur and the areas facing National Capital Region. In this state, the difference in cost between the traditional power procurement and open access is considerable at 11KV and significant at 33, 66KV. A bulk consumer of 11KV can save up to Rs.2.52 Lakhs per month on the other hand bulk consumers at 33KV and 66 and 132KV can save Rs.26.28 Lakhs and Rs.34.92 Lakhs per month respectively. Apart from economic power procurement, the reliability factor is very much important because scheduled and unscheduled power cuts in areas of Udaipur, Jaipur and Kota are prominent and the cost comparison between DG sets as well as opportunity cost for the businesses in highly regarded with Open Access. Andhra Pradesh is the state with the
www.EQMagLive.com
most cost beneficial scope of intra state open access for industrial consumers. In this report, the comparison for industrial colonies and industrial tariff has been done with open access landed cost. For each Discom of the state, the comparison gives positive results for an industry drawing at 11kV. The highest difference for the cost of power through Discom and Open access is given by NPDCL that is of about Rs1.98 per unit. On a monthly basis, this saving amounts to Rs.71.28 lakhs. Also, if one opts for open access for industrial colonies, per unit cost benefit comes out to be Rs.1.10 for consumers procuring power from CPDCL at 11kV voltage. This amount grosses up to Rs.39.6 Lakhs on monthly basis. The net saving for this category of consumers (5MW) procuring power from open access over other Discoms of the states is much higher. Hyderabad and Vishakhapatnam – the most favorable cities for upcoming ITIR projects proposed by the Government of India, can attract even more of such projects by providing a better inter-regional transmission infrastructure as it is a major bottleneck now. The count of 623 consumers in the state is a clear indication of feasibility of OA in the state.
PRICE DYNAMICS IN SHORT TERM OPEN ACCESS The average MCP across the North, North-East, East regions, the State of Chhattisgarh (W3 bid-area) and the state of Punjab (N3 bid area) was Rs.3.06, Rs.3.08, Rs.3.05, Rs.2.09 and Rs.3.06 respectively
www.EQMagLive.com
for FY 2013-14. Prices in the Southern region (S1 and S2 bid areas) were higher as compared to prices in other regions. In S1 bid-areas (Karnataka and Andhra Pradesh) the average price was at Rs.3.65 per unit, marking a negligible increase in price over the last month. While in the S2 bid-area (Tami Nadu and Kerala), price could not even be discovered for most of the months mainly due to persistent constraints in power flow.
a comprehensive way including the price dynamics involved in all forms of Open Access and the constraints involved in the way of 100% implementation of Open Access.
The Area Clearing Prices (ACP) is different from the Market Clearing Price as the rise/fall of price in an area occurs due to the effect of transmission congestion which causes market splitting. Congestion in the corridor is made easy to understand by comparison of the actual allotment of corridor for long term contracts with the capacity available for short term markets. If the flow is more than the capacity, the ACP comes into picture so that excess demand is trimmed. And if the flow is not more than the capacity, MCP is calculated for the whole area. This is because if the flow is more than the capacity at the market price for the whole area, market splitting takes place. The average ACP (DAM+TAM) for NEW regions for the FY 2013-14 remained at Rs.2.92 per unit, , whereas in S1 bid-areas (Karnataka and Andhra Pradesh) the average price was at Rs.5.05 per unit, marking a negligible increase in price over the last month.
