editorial Power Play It is quite disheartening to witness that even after the 66 years of independence, India still has 75 million households without access to electricity. The per capita consumption of power in rural households is only eight units per month compared to 24 units in urban households. www.eprmagazine.com

Till now, only two states — Gujarat and Chhattisgarh — are capable of providing 24-hour power supply. Only three states have discoms that are profitable without any subsidy are West Bengal, Goa and Maharashtra. Unexceptionally, power is one of the core issues for the ongoing general election. Almost every party promises to provide adequate electricity that also in a cheaper rate. But nobody reads out their roadmap that how they are going to make it. Almost all political parties across the nation pledge to provide 24-hour electricity in their election manifesto. Whereas, not surprisingly, the party which was at the helm for past 10 years, is once again coming with a promise of 24-hour electricity across the country over the next 5 years. Howver, following the model code of conduct for general elections has come into force; many crucial decisions related to power sector are on hold. Orders on new rates have been held up in several states, including Punjab, Odisha, Karnataka, Andhra Pradesh and Assam. Though states like Delhi, Haryana and Maharashtra have already announced lowering of consumer tariffs by increasing subsidy, they could not implement the same due to the 16th Lok Sabha elections. The implementation of model code of conduct has toppled the solar power sector too. Major issues related to amendment of Electricity Act and addressing fuel-shortages are also pending cabinet approval. Whatever the situation may be, the power sector in India will certainly breathe a sigh of relief, once the election is over. Hope you will enjoy reading this issue as always .

Power Update Vikram Solar commisions 100KW solar minigrid system
Gyanesh Chaudhary, Managing Director, Vikram Solar, stated, “Decentralised renewable energy solutions like solar-powered intelligent minigrid systems can be powerful game changers in the remote and rural areas of India. This will not only support the Rural Energy Mission but also do away with the 20 per cent T&D losses which is generally experienced by huge transmission and distribution network.”
OIL’s inaugural issue of $1 bn dual-tranche USD unsecured bonds Vikram Solar has commissioned a 100-KW solar minigrid system in Bahal, Haryana. The minigrid will help power six residential blocks, consisting of 35 households in the village. These households have been connected at load end with auto changeover. The intelligent minigrid system has used state-of-the -art equipment including crystalline solar PV modules manufactured by Vikram Solar and inverters by SMA (Sunny Boy). One set of off-grid inverters charges a set of batteries during the daytime. These batteries create a “DC Bus” inside the control room. Another set of string inverters, which are installed in the PV yard, sense this dummy grid and synchronise. The total power is now made available through the dedicated grid to the consumers. Again, during the night, the consumer load is fed by the off-grid inverters with batteries acting as a backup. Intelligent sensing options both at the power generating source end as well as the at the consumer end manage the load variation and help in keeping the system balanced all the time.
Oil India Ltd. (OIL) announced that it has made an inaugural $1 billion dual-tranche USD unsecured bond issue in the international capital markets. The RegS bonds were issued in two tranches of $500 million each 5-year and 10year tenor. The Bonds are rated Baa2 by Moody’s and BBBby Fitch. The bond issue was oversubscribed by 9.2 times approximately which is one of the largest order book for a USD issuance out of India. This was the debut foreign currency bond issuance by OIL and is the largest ever issuance from an Indian Quasisovereign corporate. OIL intends to use the bond proceeds to refinance its bridge loan availed for the recently concluded acquisition of stake in Rovuma block in Mozambique. In terms of geographic distribution, 67 per cent of the bonds were distributed in Asia, 31 per cent in Europe and 2 per cent in off shore US accounts.

Tata Power carries a substantial portion of bulk power requirement of Mumbai Tata Power carries a substantial portion of the bulk power requirement of Mumbai. The company’s transmission network comprises approximately 1,100 circuit kilometre of 220-KV/110-KV lines and 20 receiving stations spread across Mumbai. Power carried by the Tata Power transmission system is utilised by all the four distribution companies operating in Mumbai. Tata Power has transmission schemes approved by the MERC, including installation of a 220-KV transmission line from Kalwa to Salsette, a 220-KV Trombay Dharavi Salsette transmission line, a 145-KV GIS (gas insulated switchgear) at Bandra Kurla Complex, a 145KV GIS at HDIL, Kurla; a 220-KV GIS at Mahalaxmi, a 75-MVA transformer with a 33-KV GIS at Parel, and replacement of a 22-KV bus section at Dharavi. An islanding system is in place in the network of Mumbai, which isolates it from blackouts caused by faults in national grid. The transmission system is the link between the generating stations and the distribution companies for transmitting power from the generating stations and also is the corridor for bringing in power from outside Mumbai. Speaking on this, S Padmanabhan, ED - Operations, Tata Power, stated, “Tata Power has a robust, reliable transmission and distribution network in Mumbai. Today Tata Power is a major supplier to retail and bulk consumers of electricity including railways, refineries and industrial/commercial complexes.”

FICCI opposes states’ move to curb open access in power sector “Open access to the transmission and distribution network is the cornerstone of the Act, which was meant to unshackle the power sector by fostering competition, transparency, efficiency for the ultimate good of the consumer as well as the sector,” said Dr A. Didar Singh, Secretary General, FICCI.
T
he Federation of Indian Chambers of Commerce and Industry (FICCI) strongly opposed the recent move by the states to curb competition in the power sector by invoking Section 11 of the Electricity Act, 2003 and restricting open access. “Once again, instead of provisioning for sufficient electricity to meet consumer power demands, States have decided not to pursue the spirit and provisions of the Act. What is unfortunate is that even after 11 years, the implementation of the Act continues to remain a challenge,” FICCI said issuing a statement. Those, of course, are not rare incidents and to a certain extent expected in view of the approaching elections, it adds. Dr A. Didar Singh, Secretary General, FICCI, said, “Open access to the transmission and distribution network is the cornerstone of the Act, which

was meant to unshackle the power sector by fostering competition, transparency, efficiency for the ultimate good of the consumer as well as the sector.” According to FICCI, today, over 2,400 consumers and more than 200 captive generators across the various industry and commercial segments including steel, aluminium, textile, glass, automobile, pharmaceuticals, chemicals, commercial complexes, malls, educational institutions, group housing societies are leveraging open access to optimise their costs. Competition in power supply is critical for commercial as well as social growth of the nation. FICCI reiterated certain imperatives for bringing in competition in the real sense: • The States must realise that the open access is an opportunity and not a threat. • Segregation of content and carriage, both structurally as proposed in the
most recent amendments to the Act initiated by the Ministry of Power, and operationally, will go a long way in implementing open access and ushering in the much-needed transparency. • Strengthening of Section 11, as also proposed in the most recent amendments to the Act, is vital in order to prevent its misuse by the States. The term ‘extraordinary circumstances’ mentioned in the Statute must be defined and usual shortage of power should not qualify under this provision. • Implementation of a road map pertaining to the reduction of crosssubsidy surcharge as proposed under the Act must be pursued with alacrity. • On the operational front, there is need to streamline and expedite the process of securing clearances for open access. Instituting a centralized electronic open access registry is one of the possible solutions for reducing time taken.

CII slams Gujarat, Karnataka for disallowing open access in power “Open access is at the centre of the new Electricity Act 2003 and must therefore be supported and pursued by all stakeholders in the electricity business,” said Anil Sardana, Chairman, CII National Committee
T
he Confederation of Indian Industry (CII) raised concern over the Gujarat and Karnataka governments’ decision to disallow sale of electricity through the Open Access system. It said the decision could negatively impact operations of close to 200 industrial consumers. “With this decision coming into effect, industrial electricity consumers (consumption of over 1 MW) in Gujarat will now buy power from within the state at ` 6-7 per unit as opposed to the ` 4-4.5 per unit charged by power exchanges,” CII said in a statement. “On similar
lines, in Karnataka, the choice of power generators to sell power to consumers outside the State has been curbed with the State restricting power sales within the boundaries of the State.” Gujarat has been facing short-term challenges on their transmission system due to grid disturbances and has thus restricted consumers in two of their distribution companies from buying electricity under short-term open access due to technical constraints in transmission segment. The Karnataka Government has invoked Section 11 of the Electricity Act 2003 to enforce this. CII observed, “This decision challenges the principles of open access in the Electricity Act.” Currently, over 2,400 industrial and commercial consumers - steel, aluminium, textile, glass, commercial complexes, malls, etc. have been procuring electricity from the power exchanges leveraging open access. Open access, is seen by many as a very

important provision that was introduced in the Electricity Act 2003. The provision is intended to unshackle the power sector by fostering competition, transparency and efficiency for the ultimate good of the consumer as well as the sector. Anil Sardana, Chairman, CII National Committee on Power and Managing Director, Tata Power commented, “The States need to promote the spirit of competition and choice to customers. Open access is at the centre of the new Electricity Act 2003 and must therefore be supported and pursued by all stakeholders in the electricity business. The consumer’s choice to explore competitive electricity price thereby contributing to economic competitiveness of their products and services is an important aim of the Act. It is hoped that such competitive spirit shall be maintained duly tiding over short term challenges of capacities in transmission system etc.”

Without jobs, India’s demographic dividend will be a disaster: S.C. Bhargava
B “As a country we add so many people and if we don’t create 10 million jobs every year, the demographic dividend will become a demographic disaster,” says S.C. Bhargava, Senior Vice President, Electricals & Automation, L&T
acked by the strong performance in Dubai and Qatar markets, L&T’s electricals and automation business is expected to clock ` 5,000 crore turnover in FY14. However, the slowdown in Indian market continues. In an exclusive interview with Subhajit Roy, Mr. Bhargava talks on the company’s performance, status of Indian manufacturing sector and Chinese-way of boosting manufacturing industry. He also outlines his expectations from the upcoming government.
How did the L&T’s Electricals & Automation business perform during the last fiscal? In 2012-13, we did ` 4,500 crore and in 2013-14 we should achieve a turnover of around ` 5,000 crore clocking 10-11 per cent growth.
How could you achieve this 10-11 per cent growth when the industry is going through a slowdown? Increase market share a little bit in India, look at opportunities outside, and look at adjacent geographies.
Which is that one strategic move that helped you to achieve growth even in difficult time? I think significant increase in the number of people placed outside to look at opportunities there. To be very specific, the opportunities in Dubai and Qatar helped us significantly. Qatar is full of buildings just now as it is preparing for 2022 FIFA World Cup. Dubai is going to organise the World Expo in 2020. So,
18
May 2014
both events have given opportunities to Indian companies.
How much do these two markets contribute to your turnover? These two markets should be giving almost ` 500 crore of sales for L&T’s E&A business in 2013-14.
In current scenario, which segment gives you better business? When infrastructure growth takes place, you see a lot of activities in the MV (medium-voltage) segment. When residential buildings take place there are lots of opportunities for LV (low-voltage) business. In India and Qatar, we see a lot more infrastructure activities whereas in Dubai we see lot more buildings coming up. So, we got to see the balance between LV and MV demands.
You are also the Chairman of Tamco Switchgear which was acquired by L&T. How this acquisition complements your business in India? Till 2008, L&T was a company which was only into LV switchgear; we made equipment 400V and below. We didn’t make any high-voltage equipment. In 2008, we acquired Tamco for $100 million. Tamco was a specialist company which grew in Malaysia and established base in South-East Asia and MiddleEast. They did not have any operations in India. So when we acquired it we had geographical adjacencies and product adjacencies. To that extent, it was a perfect fit for two companies – it enabled us to offer solutions right up to 33kV.
Electrical & Power Review
Today, how much Tamco contributes to L&T’s business? In FY14, we have clocked almost ` 850 crore.
How do you look at the FY15? We are on the stages of finalising our budget and I guess L&T will make guidance sometime in May. But let me put it to you, the 10-12 per cent growth during the last fiscal, we hope we will do better than that next year.
Looking at the current market scenario, will it be possible? We are actually looking at H1 remaining very similar to what has happened during the last fiscal but we expect H2 to become better. The new government has to come and prove itself also.
If the same political parties come in to power, then? Even if the same government comes they will have to come and do something differently. So I expect things to improve. I said it at different forums and I don’t mind telling you also. As a country we add so many people and if we don’t create 10 million jobs every year, the demographic dividend will become a demographic disaster. Finally it’s a question of young people coming into job market to find jobs. The number is 10 million a year! Ten million a year jobs require 6 per cent growth; if you do not get 6 per cent growth you are gone.
Do you expect any kind of reforms in taxation? Any government that comes will have to pass the GST and DTC. These are the two big factors behind slowdown. Lack of GST actually slows down business and makes it troublesome.
What’s your take on the cheap import from China? I strongly believe that while we must have freedom of trade without barriers, we must also recognise that China has a lot of advantages. In a country like India it is interesting to see manufacturing is burdened with taxes. If you look at the whole industry it has three parts — manufacturing, services and agriculture. There is no tax for agriculturerelated activities and service sector has started paying tax recently. So, all the tax burdens come on manufacturing because it is easy to implement. Today, manufacturing industry is so heavily taxed in India that it is uneconomical. China follows the exact opposite - taxes everybody, gives weightage to manufacturing and makes it attractive for them to manufacture. Energy and raw material costs are the lowest in China. So when you have these two basic parameters low, the production costs have to be low. In India, to create 10 million jobs, the government has to find ways to reduce the tax burden on the manufacturing sector.
So what are your suggestions to promote manufacturing industry? They got to look at how to treat things. I am not saying we should have tariffs but we must have a level playing field. Level playing field means the tax burden cannot just be on the manufacturing sector, it has to be on everybody else like the way China is doing.
COVER STORY
Captive power: no more power deficiencies This article takes a look at the need of captive power units, driving factors, key trends as well as the future outlook
A
dequate electricity supply plays a central role in development and realisation of the country’s economic goals. Economic growth gets impeded both by poor electricity supply quality and electricity supply interruptions, particularly in the peak period. To reduce the gap between supply and demand for electricity as well as to make best use of energy resources, the captive power plants (CPPs) are certainly good, reliable options.
What is captive power plant? Captive power plants, normally established by an industry to meet its own requirements, include generation sets. These plants are meant for catering
20

to the needs of a particular industry, or consumer, or group of industries and consumers for their own use, which ideally should not be less than 50 per cent of the total output of the plant. Captive power plants operate independent of wheeling to grid. The main purpose behind establishing CPPs is in-house power generation for industry and not selling the power to grid of electricity boards. CPPs are generally associated with specific industrial complexes, and their output is almost entirely consumed by that concerned industrial plant. Another term that may sometimes be synonymous is ‘cogeneration’ in which
the power plant produces multiple forms of energy (e.g. electric power and steam), and where both raw materials are for a related industrial process. Reading this, one must be eager to know how does a CPP work? Well, probably the most classic example is that of a paper mill. Boilers produce steam. The steam passes through a turbine that spins a generator to produce electricity. Exhaust steam from the turbine is then used as a source of heat to dry fresh paper before it is finally condensed into water and returned to the boiler. The boiler itself burns the bark that itself cannot be used to make paper and would otherwise be a waste material. In addition, the process of making pulp produces chemical waste
Electrical & Power Review
COVER STORY called ‘black liquor’ which can also be burned as a fuel in a boiler.
Need of CPPs Energy-intensive industries across the country rely on captive power generation to meet their electricity requirements. The sustained electricity demand-supply gap, lack of reliable power supply from the grid and high tariffs are key reasons for industrial consumers to consider the power option. And that underlines the importance of CPPs.
Choice of a particular CPP The choice of a type of captive power depends on factors like requirement of baseload or backup power, industrial processes, fuel and water availability. In some cases, this choice depends on capital cost of the concerned project too. While large industries like metals, mining, cement and petrochemicals typically set up baseload CPPs, smaller industrial units depend on a mix of grid power for meeting their baseload requirements and CPPs for the essential backup power needs. Here we should take into consideration the industry shares in captive units as well. Industries, mostly the primary producers like aluminium, chemicals, cement, fertiliser, iron and steel, paper, sugar etc. have tremendously contributed in sector of captive power generation.
Advantages There are some advantages of setting up captive units. They are accrued in the form of assured power supply, reduced wastes, fuel flexibility, and lower tariff. Further CPPs can help lower energy cost in the industries, especially in some specific cases where it forms a significant proportion of total production costs.
Current scenario There are many industries which consume a large chunk of the power generated and distributed by the utilities. As these industries also provide the larger portion of the revenue, they have to compete consistently in the
Electrical & Power Review
global market for their products and services. Non-availability, poor quality and reliability of grid power along with exorbitantly high tariffs have a significant impact on the competitiveness of the industry in market. Being a part of such scenarios and facing the related issues, there came a need of sufficient power supply to these industries. And then this led to the emergence of captive generation. Captive power today accounts for at least 20 per cent of the total installed capacity in the country. The high cost (because of the crosssubsidy element) and the abysmal quality of the power were the primary reasons driving industry towards investing in captive generation facilities. For some of the process industries like chemical, aluminium, cement etc., the need for uninterrupted quality power is a necessity rather than just a mere requirement. Moreover, with advancing technologies, it was realised that the many of the power generation technologies have symbiotic relationship with the manufacturing process itself. For example the heat loss consequential to certain chemical processes could be used for power generation, or the need for steam (in the manufacturing process) besides power could be supported with highly-efficient power generation technologies. We observe that galloping demand for power and mounting constraints in its generation have forced electricity boards of some states in country to impose power cuts. User industries have been forced to go for captive power plants to tide over the situation. Electric power generation is a state controlled subject. However, government has liberalised captive power generation for the user industry for bridging the demand-supply gap. The fact that private industries use captive power answers the question of financial viability. Industries which have a high value added for electricity input will
naturally insulate themselves through standby power. From the national point of view, the issues are somewhat different. Here the objective of the policy maker will be efficient resource allocation. The alternatives differ for short and long runs. In the short and medium run, power cut is given and the alternatives may be to impose a uniform power cut on industries, impose an ‘optimal’ power cut, minimise production loss and unemployment, and allow for captive power generation. Captive power plants don’t necessarily have to be islands that are disconnected from ‘the grid’. In fact, it is often the case that the demand of the industrial process exceeds the capacity of the captive plant, and power must be taken from the grid to make up the difference. Also, there must be some provision to bootstrap the integrated process into operation. Often this means relying on grid power to start up the plant following an outage. And it is possible that there are times when the captive plant will produce more power than can be consumed in the industrial process as per the requirement of various projects, and rather than throttle back the excess is sold to the grid.
Research findings As per India Infrastructure Research, the installed captive power capacity base stood at 69,500 MW as of 201213. This amount is almost one-fourth of the country’s total installed capacity. One important aspect that needs to be taken into consideration is captive power capacity addition is proportional to the industry’s growth momentum. Capacity addition has moderated over the past few years, primarily due to slowdown of industrial growth in the country. This can be attributed to the slow pace of investments, narrowing margins of the corporate sector, weak global economic environment and infrastructural bottlenecks. Further, fuel supply issues have aggravated in recent years leading to developers holding on to their capacity addition plans.

“It is a natural requirement of nation and industry to install captive power plants for attaining global competitiveness,” says Rajiv Agrawal, Secretary, Indian Captive Power Producers Association (ICPPA)
aptive power plants (CPP) are necessary for continuous availability of quality power, and the shortage of fuel and coal is affecting power generation at CPP. In an exclusive email interaction, Rajiv Agrawal discusses issues surrounding captive power plants and their initiatives to promote the plants.
How do captive power plants contribute to Indian energy and power industry? It would be interesting to start with the historical contribution of CPPs to Indian growth story that will continue to stay in future. With onset of economic liberalisation, in 1991 the government amended the Electricity Supply (Act) 1948 to allow the entry of private investors in power generation and distribution. Till that time, approvals for setting up CPP was a cumbersome process with CEA giving techno-economic clearance. After failure to receive investment in IPP and slow industrialisation pace, by 1995 union government realised that the power availability to industry can improve only if they are persuaded to invest in CPP and get access to transmission system. Accordingly, the ministry advised all states to form suitable policies. Captive power plants have been installed by industry, deploying huge investments and are backbone of large industry sectors responsible for
22

national growth and infrastructure build-up, i.e. cement, chemicals, steel and iron, aluminium, zinc, paper, textile, tyre etc. These industries are first link in the national value chain by converting natural raw materials to finished goods or raw material used in downline industries. All continuous process industries and factories working in three shifts can’t survive without CPP or backup power. Captive power plants are the only available, efficient (PLF > 90-100 per cent), economic source (least T&D losses) of un-interrupted quality power for industry. In case of co-generation CPP, the thermal efficiency can reach 50-80 per cent for “fuel-power cycle” as against 35-42 per cent for most efficient sub-critical and super-critical IPP. CPP are ensuring sustained GDP growth and development, generation of wide scale employment and earning incremental revenue for government through taxes and duties. CPP-based industry contributes to about 18 per cent of nation’s GDP (excluding services), employs 16 per cent of direct workforce (excluding agriculture) and to about 5 per cent of nation’s forex earnings. As per 2004-05 data, these industries added about ` 325 billion to national tax pool. All these figures do not include indirect employment and further value addition. Captive plants take the pressure away from national grid. If SEBs/IPPs were to take load of CPPs, the entire grid will
Electrical & Power Review
EPR PERSONALITY need a quality upgrade and existing power deficit in country will increase three folds. If 100 per cent of linkage coal is given by Coal India Ltd. (CIL), CPPs can also pump excess power into the grid. Assuming 10 per cent power to be excess, about 5,000 MW may add to the national power pool from already installed CPP capacity.
During power crisis and shortage, what role do captive power plants play? As explained, policy shift in 1995 towards CPP was a result of power shortage, affecting economic wellbeing of the nation. States realised that assured, uninterrupted, quality power at affordable price are some of the prerequisite for setting up industry. Most states formed policies giving incentives to CPP to accelerate industrialisation in their states despite overall power crisis and states achieved visible positive results. A system of allotting fuel and coal to CPP was put in place by Coal and Petroleum Ministries. Creation of captive power generation capacities also helped power utilities spare the power and grid-capacity for the public at large. During national grid failure in 2012, the industries with CPP were least affected, proving advantage of distributed power generation. You may find it interesting that the actual positive roles of CPP for nation building are already recorded by policy makers in National Electricity Policy 2005.
How did ICPPA help in promoting captive power plants? It is a natural requirement of nation and industry to install CPP for attaining global competitiveness. No one needs to promote CPP. People just need to remove obstruction in fuel supply to CPP, stop discrimination of fuel quantity and price, and give equitable treatment also for power transmission and taxes by states.
Electrical & Power Review
ICPPA takes care of interests of CPP because they are scattered across country and fragmentation lowers their negotiation power. Therefore, as an all India association, ICPPA is regularly taking up both the policies and operational issues with various ministries and agencies.
and LOA for CPP. As a result, 382 CPP applications for 34,000 MW are pending. As per our information, a large number of these CPP are commissioned or at advance stage. In the absence of linkage coal, many of CPP have been shutdown or operating at partial load.
A few examples illustrate consistent efforts of ICPPA and crucial role it plays in an environment with too many contenders for limited natural resources. ICPPA provided crucial inputs during formation of New Coal Distribution Policy (NCDP 2007) to keep CPP at par with other power producers. During NCDP review by coal minister in June 2011, ICPPA’s view of equitable and non-discriminatory treatment to CPP also got resonance from the Planning Commission thus protecting interest of CPP.
In 2012 it was decided that for entire 12th Five-Year Plan, coal will be given only to IPP for about 78,000-MW projects. Reluctantly, CIL agreed to sign FSA for 50 per cent coal quantity due to limited coal availability. However, the government forced CIL to sign 65 per cent of LOA with 15 per cent imported coal though materialisation will be lower. Everyone knew and also witnessed in past 2 years that IPP can’t breakeven at 65 per cent PLF level and there are few takers for costly power, based on imported coal. Thus the rest of the country has been denied the equitable opportunity to get coal.
ICPPA clearly highlighted that from the very beginning. Many aspects of NCDP implementation are lagging due to the efforts made by interested groups to corner this scarce natural resource. For example, NCDP provides coal distribution method for CPP with more the 1 MW, but from the beginning CPP with less than 5 MW never given coal and now even up to 10 MW CPP is denied the right on this natural resource. ICPPA contributed to reversal of price hike after CIL raised coal prices up to 250 per cent while changing over from UHV to GCV bands pricing.
What are the challenges faced by this sector and how do you deal with them? With about 51,000 MW, captive power capacity in the country roughly 18 per cent of total installed capacity. Out of it, about 40,000 MW are coal fired; making CPP sector, and thereby the industry, highly dependent on availability of coal. Precisely, this is the biggest challenge faced by CPP. Since 2009, the Coal Ministry has stopped issuing fresh coal linkage
Based on promises by successive central and state governments from 1995 onwards, CPP are sustaining global competitiveness for Indian industry. However, efforts are being made by a section to reverse this time wheel of CPP. Post “National Electricity Act 2003”, a large number of businessmen and politicians diversify business and grab early opportunity in the power sector. All efforts were made to get assured coal supply for themselves, displacing CPP and industry requirements for coal. Unrealistic gross number of IPP applications received by the Coal Ministry for coal linkages will take care of Indian power demand 20-40 years from now. Another big stumbling block is discrimination in levy of taxes and other power charges on CPP by states. Many provisions of Electricity Act 2003 and policies therein are denied or curtailed for CPP. RPO obligations on CPP, without getting full coal at price equal to IPP, are a penalty that is being contested by industry. If policy makers went logical, this could be converted as incentive,
May 2014

EPR PERSONALITY and industry could have achieved much higher than targeted. Similarly, non-conventional and renewable energy projects can serve as CPP, but somehow the incentives available to supply to grid are denied or skewed if used as CPP. RPO obligations and REC related to co-generation are still being denied despite creating high thermal efficiency that reduces much of green house gases. Similarly, power by waste heat recovery (WHR) is being placed as “do it” or face penalty in place of giving incentives and REC. During renewal of CPP FSA in 2013, CIL imposed 25 per cent cut on FSA quantity because CPP was not ready to buy 25 per cent A and B grade (G1-G4) unsold costly coal. After ICPPA took up the matter with CIL chairman, the condition was withdrawn (except for ECL and SECL). The sad part is that CIL is cutting CPP linkage for diverting the coal to IPP and save short supply penalty. From 2011, CIL is charging 30-35 per cent extra from CPP. This goes against NCDP and policies under Electricity Act 2003 to give level-playing field for all power producers. While national coal shortfall has been 10-15 per cent, CIL forced 50 per cent cut on CPP linkage while IPP get 100 per cent of linkages. At present due to low demand from IPP, a lot of coal is not being lifted. While a large number of operating CPP is waiting to get linkage coal, India never had sufficient coal to meet committed demand of all users. Dissolving of standing Linkage Committee (Short Term) by the Coal Ministry has taken away flexibility to give coal to CPP at such occasions. Railway diverts the CPP rake programs to IPP resulting backlog. Many of these subjective instructions are given by top central or state government functionaries, making it difficult for zonal railway to overrule. Then railway also monitors IPP with lower coal stocks and diverts all coal rakes to them.
24
May 2014
Many of these government IPPs have perennial problems in maintaining stocks but in place of removing root cause, others like CPP and industries are penalised.
Railway blames CIL to have signed toomany FSA (with IPP) beyond loading capacity and to stop CPP and industry rakes if coal production is reduced due to problems related to operations or law-and-order or natural factors.
How do you deal fuel shortage? The fuel shortage is a national issue. While a lot is being discussed and done at the government level, ICPPA keeps interacting with the policy makers. We also try to question rationale of broad decisions so that policies and their implementation can be corrected. Now the question comes — how long can India sustain vicious cycle of costly coal imports (increase trade deficit) on borrowed money (through FDI) and not able to export goods due to reduced global competitiveness (costly production with higher power cost from imported coal)? The Planning Commission projected coal import to reach target generation if India wants to maintain 8-9 per cent growth. What actually transpired is that a lot of states are not ready to buy costly power, based on imported coal. At the same time, increasing trade deficit due to higher coal import is disturbing nation. CIL want to link Indian coal price to import landed price but forgets that to remain globally competitive, Indian energy cost can’t be increased while other nations are boosting export by direct and indirect subsidies. The issue of fuel shortage is a story revolving around cornering of this scarce national resource. Decision making by our up-right bureaucrats and sensitising them from time to time is helping in sustaining operations. For example, ICPPA took up with Railway Board to reverse decision of SEC railway to cancel 20 per cent allotment for CPP from October ‘12 to March ‘13 and prevented more than ` 100-crore loss for CPP. Again in this year, ICPPA is sensitising railways not to lapse CPP rakes due to tussle between zones and CIL subsidiaries.
On the other hand, CIL points to nonavailability of rakes. While CIL was forced to sign IPP FSA in place of equitable distribution of coal to all stake holders due to political intervention. Today more and more industries understand the need to consolidate efforts under the banner of ICPPA so that the abrasions for CPP policies and operation can be ironed out. Through EPR, we appeal all CPP units to inform us their problems and challenges so that the same can suitably be taken up with relevant authorities. Also, many CPP are experimenting with mixing various fuels like petroleum coke, imported coal, husk and wastes etc. with coal to reduce cost and increase efficiency for their sustenance. Wherever possible, they are using cogeneration and waste heat recovery processes. Industries have also started investing in non-conventional and renewable energy sources to diversify some risks.
How do you see the future of captive power plants in India? The CPP are pre-requisite for sustainable and uninterrupted availability of quality power for industry. As mentioned earlier, to serve quality requirement for 10 per cent industrial power consumption, nation can’t upgrade remaining 90 per cent infrastructure. While IPP can give power to trade and public at large, CPP could boost industrialisation and employment generation from 1995. Equitable distribution of coal at same price to all power producers will remain a critical factor. Therefore, the government has to rise to the occasion and support CPP.

“Captive power plants enable industries to focus on their core competency and improve productivity in their operations,� says Rakesh Sarin, Managing Director, Wartsila India
aptive power plants not only enable industries to improve productivity in their operations, but also help in reducing operating costs due to improved quality of power. In an exclusive interview with EPR, Rakesh Sarin shares how captive power plants help industries function smoothly at all times.
What is the importance of captive power in India? Captive power plants fulfil an important role in providing reliable, affordable and quality power to industries. The availability of power through the grid has improved quite dramatically over the past few years, but there are still issues on quality and affordability, especially during peak hours. Captive power plants help industries function smoothly at all times, enhancing productivity.
Industries are facing the brunt of power shortage, how do captive power plants respite the need for power? Captive power plants as the name suggests are set up by industries to meet their own power requirements without depending on the grid. However, not all industries can set up their own captive power plants as the investments can be large, so we can get a group of such industries together to set up group captive power plants wherein we can participate in the equity, and the developer takes responsibility for the supply of quality and reliability of power supply.

What are the advantages of captive power plants? Captive power plants enable industries to focus on their core competency and improve productivity in their operations. They also bring about reduction in operating costs due to improved quality of power.
What are the challenges faced during installation of these plants; and also in its maintenance? There are a few challenges to set up captive power plants; namely, space and fuel. However, Wartsila multi-fuel power plants require very little space, e.g. a 100-MW plant would need about 5-6 acres. Maintenance of captive power plants is carried out by qualified, trained personnel.
How do you deal with the issue of fuel shortage? Wartsila offers multi-fuel solutions for our customers. We have sets which can run on heavy fuel oil, diesel and natural gas. Our tri-fuel sets are capable of switching among fuels seamlessly.
How do you see the future of captive power plants in India? Captive power plants are facing challenging times as the quality, availability and reliability of power in the grid have improved quite a lot in recent times. However, there are industries which would invest in captive power plants as it reduces their dependence on the grid. It gives them more control over their processes which increase productivity.

Steam turbine
powering power sector
With its higher thermodynamic efficiency and a lower power-to-weight ratio, steam turbine is revolutionising the power sector
S
team turbine is a mechanical device that converts thermal energy in pressurised steam and uses it to do mechanical work on a rotating output shaft. The original steam engine, largely powered the industrial revolution was based on reciprocating pistons. This has now been almost totally replaced by the steam turbine because the steam turbine has a higher thermodynamic efficiency and a lower power-toweight ratio.
Steam turbine as industrial application Steam turbine systems are very commonly found in paper mills as there is usually a variety of waste fuels from hog fuel to black liquor recovery. Chemical plants are the next most common industrial user of steam turbines followed by primary metals. There are a variety of other industrial applications including the food industry, particularly sugar mills. There are commercial applications as well. Many universities have coal-powered CHP (Combined Heat and Power) generating power with steam turbines. Some of the facilities are blending biomass to reduce their environmental impact.
Choosing steam turbines While steam turbines are competitively priced compared to other prime movers, the costs of complete boiler or steam turbine systems are relatively high on a per kW of capacity.

This is because of their low power-toheat ratio, the costs of the boiler, fuel handling and overall steam systems, and customisation of most installations. Thus, steam turbines are well-suited to medium- and large-scale industrial and institutional applications where inexpensive fuels are available.
Steam turbines for power sector The steam turbine is ideal for the very large power configurations used in power stations. The steam turbine derives much of its better thermodynamic efficiency because of the use of multiple stages in the expansion of the steam. This results in a closer approach to the ideal reversible process. Electrical power stations use large steam turbines driving electric generators to produce most (about 80 per cent) of the world’s electricity. The advent of
Electrical & Power Review
large steam turbines made centralstation electricity generation practical as reciprocating steam engines of large rating became very bulky and operated at slow speeds. Steam turbines can also be used directly to drive large centrifugal pumps, such as feedwater pumps at a thermal power plant. While talking about the importance of steam turbines in power sector, Navin Dewaji, Vice President - Power Generation Division, Energy Sector, Siemens Ltd., shares how Siemens’ small steam turbines are benefiting industry like its compact design minimises space requirements of installation as well as low maintenance costs due to easy access to mechanical components.
Challenges There are some challenges when it comes to operation and maintenance
of these turbines. “Turbine operation can get affected if it is not handled as prescribed,” says Mr Dewaji. “Poor inlet steam quality can cause scaling which affects normal turbine operation. Also, running turbine at parameters which are outside the allowed limits can cause damage to sensitive components of turbine and may cause damage.”
Changing trends These days the industry is observing some changing trends. These are: • Customers are moving towards higher MW ratings as average size of production firm is increasing • More focus on energy efficiency of steam turbine • Increasing use of small steam turbines for waste heat recovery • More focus on eco-friendly power generation, suiting steam turbine by using biomass or solid waste as fuel.

T
oday energy efficiency is of dominant importance due to the ever-increasing electrical energy demand, increasing awareness around global warming, and the increase in prices of fossil fuels. Electrical motors are the most important type of electrical load in every industry. Moreover, Electrical Motors Driven Systems (EMDS) consume approximately 65 per cent of energy consumed by the industry.
mid-size L.T motors with output power of 0.75 kW to 375 kW. Asynchronous alternating current (AC) induction motors are most frequently used and consume the most energy. These motors are either sold to original equipment manufacturers (OEMs) and integrated into pre-packaged electromechanical products (such as pumps, fans, compressors, etc.), or sold as standalone motors that final customers then integrate into a specific application on site. Such standalone motors are used in large volumes, according to standardised input power and size specifications, with varying channels to market and integration into electromechanical systems.
Electric motors and the systems they drive are the single largest electrical end use, consuming more than twice as much as lighting — the next largest end use. It is estimated that EMDS account for between 43 per cent and 46 per cent of all global electricity consumption, raising about 6,040 tonnes of CO2 emissions.

Major points in revised IS12615: 2011 This is the second revision. The first revision happened in 2004. The 2004 version had only two levels – Eff1 and Eff2 having a scope of 2P and 4P motors up to 160 kw, and 6P motors of up to 132 kw. The testing methodology was also different back then. This standard got harmonised in 2008. After that the testing procedures and efficiency classes, i.e. IE1, IE2 and IE3 were defined. Going further, in 2011, India also harmonised with the global IEC standard as well as came up with its IS12615:2011. The scope of IS12615: 2011 standard was revised/extended from 0.37kw to 375kw, over IS12615: 2004. The

total band of IS12615: 2011 standard has been classified into IE2 and IE3 efficiency classes. Further, parameters like breakaway torque, current and fullload current are included. The standard also specifies that IE2 is the baseline motor efficiency class. Going further, BIS has created a road map stating that by January 2014, the scope shall be IE3.
Barriers in penetration of highefficiency motors in Indian market • Lack of awareness among motor purchasers, regarding the potential for energy and cost savings by using more efficient motors within energyefficient EMDS. • Company organisational structures that manage their equipment procurement budget separately from operations and maintenance budgets. • The fact that motors are often

needs to revised and updated with new standard, i.e. by including IE2 and IE3 motors in the specifications.
The major barrier is that SMEs have to change their mindset toward the life cycle cost of the motor. Every purchase in industry units needs to weigh the savings that can be achieved through energy-efficient motors. There is always a tendency in the Indian market to go for the lowest initial cost instead of analysing the life-cycle cost. However, as this cost is hidden, people tend to take the decision to purchase a motor, based on the initial cost which amounts to only 4 per cent cost which goes for purchasing. Almost 88 per cent of the total lifetime cost of the motor is because of the consumed energy or the running cost.
Preventing influx of inefficient motors as imports
Hence every purchase and technical specification for these EMD systems
Going further, if BIS standard like IS12615 are made mandatory under energy conservation act 2001, we can save our nation from being flooded with imported inefficient motors. In the last two quarters, there have been large imports of motors. In 2011, China, Korea, Brazil and Europe made it mandatory to sell minimum IE2 efficiency motors in their countries. We need to follow this example.

GUEST COLUMN IEC 60034-30, the International Electrotechnical Commission introduced the precisely defined and open-ended international efficiency-classification scheme using IE1, IE2 and IE3 as the classification system. Globally, many developing countries the motor standards are harmonised to the international standards. Hence, with the international standard in place and all countries harmonised to international standards and with the same efficiency classes in all countries, solves the problem of export barrier. BIS has formulated the testing standard IS15999, harmonised to the international testing standard IE 60034-2-1.

As per the study by international energy agency, general purpose industrial electric motors of between 0.75 kW and 375 kW consumed 4,700 TWh (68 per cent of the total for all motors); their share of global electricity demand is 30 per cent. The three economies with the highest electricity consumption for motors are China, the United States and the European Union, which collectively consumed 4,000 TWh (56 per cent of global electricity demand for motors); the addition of four more countries (Japan, Russia, Canada and India) adds another 1,200 TWh (18 per cent), which makes a total of 5,200 TWh (74 per cent). Four major motor applications dominate the electricity demand of motors: compressors (32 per cent), mechanical movement (30 per cent), pumps (19 per cent) and fans (19 per cent). In recent years, market share of more efficient motors has been increasing in many regions and countries. This was particularly the case for the United States, China and other countries, and to a certain extent, for Europe. Four standardised efficiency classes (IE1, IE2, IE3 and IE4) are currently recognised. The United States and Canada are leaders in terms of setting motor energy-

efficiency standards, as they introduced regulations for motors in the late 1990s. As early as 2002, China defined MEPS for electric motors. The European Union passed MEPS legislation for electric motors in 2009 as an implementing measure under the eco-design directive; these will replace the previous industrial voluntary agreement. Australia, Korea, Brazil, Mexico, Taiwan and some other countries with large electricity consumption from motors have already adopted MEPS, as have some smaller economies such as Costa Rica, Israel and New Zealand. However, some large motor-using economies, such as India, Japan and Russia, have not yet adopted MEPS.
Energy saving industrialisation

rapid
Energy-efficient electric motors play a very important role and the motor manufacturing industries across the globe are manufacturing motors inline with the international standards. One of the study conducted by International Energy Agency on energy consumption in electric motor-driven systems (EMDS) states that electric motors and the systems they drive are the single largest electrical end use, consuming more than twice as much as lighting — the next largest end use. It is estimated that EMDS account for between 43 per cent and 46 per cent of all global electricity consumption, giving rise to about 6,040 tonnes of CO2 emissions. By 2030, without comprehensive and effective energyefficiency policy measures, energy consumption from electric motors is expected to rise to 13,360 TWh per year and CO2 emissions to 8,570 tonnes per year. End users now spend $565 billion per year on electricity used in EDMS; by 2030, that could rise to almost $900 billion. The largest proportion of motor electricity consumption is attributable to mid-size motors with output power of 0.75 kW to 375 kW. Many different motor technologies and design types
are available, but asynchronous alternating current (AC) induction motors are most frequently used and consume the most energy. These motors are either sold to original equipment manufacturers (OEMs) and integrated into pre-packaged electromechanical products (such as pumps, fans, compressors etc.) or sold as stand-alone motors that final customers then integrate into a specific application on-site. Such stand-alone motors are produced in large volumes, according to standardized input power and size specifications, with varying channels to market and integration into electromechanical systems. Motors in the mid-size range are most commonly found in industrial applications, but they are also widely used in commercial applications, infrastructure systems and, less often, in the residential sector. In general, their main applications are mechanical movement, compressors, pumps and fans, which in turn have many types of sub-application.

afety is an undervalued term in India. Whether it is safety at home, on roads or at work, its importance is poorly understood. As shocking as the statement sounds, it is testament to the fact that most Indians have a careless attitude toward safety at the workplace. Most of the time the focus is on correction, rather than prevention which leads to excess costs and wastage of resources. The electrical industry is at crossroads. The industry is taking a conscious

effort to upgrade its processes and material usage to compare with worldclass practices and companies. The customers have become increasingly discerning and demanding and are ready to pay more for better quality electrical work. They understand that these extra expenses are paid off in the long run by efficient, uninterrupted electrical performance. In spite of the growth in the productive output of the electrical industry, there are a number of safety hazards
which have led to a loss of lives and properties. Electrical faults seem to be the major reason for industrial disasters in the country as 56 per cent of incidents are reportedly caused by them. Overheating, ageing of the material and use of sub-standard quality of electrical gadgets have been contributing to the increasing electrical fire accidents in industries. The Karnataka Energy Department has admitted that there have been 1,400 deaths in the past 3 years due to electrical accidents alone.
Electrical & Power Review
Safety & Security According to the National Crime Records Bureau statistics, 8 per cent of all deaths in industry are electrical in origin. A power failure can result in expensive shut downs, and there is more. Besides the production, loss there is a greater danger — fire. A small electrical problem can have extremely far-reaching consequences. The efficiency of the electrical grid becomes low, so the energy is spent generating heat. If left unchecked, heat can rise to the point where connections start to melt. Not only that, sparks can fly, setting the environment on fire. Insurance companies are now taking this into consideration and require regular thermal inspections. This provides new opportunities for dedicated specialists. Fire accounts for the 10 per cent of all risks as observed in the India Risk Survey, 2012.The risk of fire has been rated among the top six risks across India. The respondents from outside of India have ranked risk by fire as the No 1 risk. The manufacturing and telecom sectors have also highlighted fire as their No 1 risk. In fact, Mumbai’s fire department indicates that electrical short is one of the most important causes of fire.
What are the main causes of electrical accidents in industry? While there are multiple causes, there are three common root causes for just about any electrical incident: • Working on unsafe equipment and installations • Unsafe environment, i.e. wet environment/presence of flammable vapours • Unsafe work performance. There exists a number of ways to protect workers from the threat of electrical hazards. Some of the methods are for the protection of qualified employees doing work on electrical circuit, and other methods are geared towards non-qualified employees who work at nearby energised equipment.
Solutions to avoid a safety breach Thermal imaging has become an important tool for electrical inspections in many industries. Alerting techniques are used to warn employees of the dangers present. Training is conducted on a regular basis in the electrical industry to increase the safety quotient of all employees. But none of this can be possible without the strict implementation of preventive maintenance throughout the organisation. Alerting techniques might include safety signs, safety symbols, or accident prevention tags. Proper identification can be done using Brother printers which generate laminated labels to meet various marking requirements. A number of accidents are occurring due to silly mistakes and improper knowledge. These can be overcome by appropriate marking on various points like switches, controls, indicating lights etc. These labels are also durable enough to meet situations and services as per the workplace need.

helps avoid costly failures in power generation, transmission and distribution as infrared cameras help find anomalies before trouble strikes and service is affected. In production plants, office facilities, hospitals or hotels, an infrared camera instantly makes hot spots visible on a clear thermal image. One can scan electrical cabinets and components and survey multiple wires and connections to get an instant picture of potential trouble. Thus, the detection of the problem area and repair is before the real problems occur. Common electrical targets are fuses, electrical panels, bolted connections and switchgear. Companies like Tata Power, NPCIL, NTPC, BHEL and ISRO have been investing heavily in safety.

Energy efficiency is estimated to be a $16 billion opportunity in India” Mr Malhotra also adds, “These days energy efficiency assumes greater importance because it is most economical and reliable way of meeting the particular global local climate change. Hence, the utilisation of energyproductive lighting is important and happens to be an important portion of the modern society.” Sundeep Khurana, Vice President Lighting, Havells India Ltd., also thinks lighting is a very dynamic technology. He says, “Energy efficiency in lighting is catching up pretty well in India. LEDS are entailing a total saving of 60-75 per cent over CFLs. “Indian lighting industry put altogether is growing about 45 per cent CHER out of which LED is expected to be $400 million by 2015 which should 40-45 per cent of the total market at that point of time.” Activities to push energy efficiency Philips Lighting has time and again reiterated its commitment toward driving the switch to energy-efficient lighting. “Philips LEDs help in reducing power consumption by up to 70 per cent,” says Mr Agrawal.
GreenLED
Even Havells is catching up the technology with its in-house electronic development. “There are something called electronic drivers or electronic light engines which work like a ballast for a tube light,” explains Mr Khurana “These are purely electronic.” Electronic technology in India is evolving, and Havells has already diversified into manufacturing these electronic drivers in-house. Energy efficiency is also at the forefront of GlacialTech’s policy. According to Mr Malhotra, “GlacialTech is more focusing on producing high energy-efficient products which have low energy loss and high efficiency.” GlacialTech has LED drivers which have efficiency higher than 90-95 per cent. Its high bay, troffer light and flood lights have higher lumens per watt.
Along with its world-class lighting solutions, Philips Lighting India has taken up several initiatives to spread awareness on energy efficiency like monument makeovers and Saara Zamana Campaign. With the monument makeovers initiative, Philips Lighting contributes to monument preservation and spreads the message to switch to new-age energy efficient lighting. The Saara Zamana Campaign, which features Ranbir Kapoor and Shruti Hassan, drives consumers to switch to LEDs. Philips is driving the change to energy efficient lighting solutions by developing locally relevant products which are designed to withstand local operating conditions like voltage fluctuations, frequent power outages, diverse weather conditions etc. Influence of government’s decisions Technology companies don’t really mind to work with the government department. They are always up to spread the awareness of using LED lamps and products. They are also working with Energy Efficiency Services Ltd. (EESL), an initiative by the Government of India, in order to spread the awareness of benefits of LED products.

Industry Analysis Philips also closely works with several organisations like ELCOMA, IGBC, BEE, TERI etc. to educate consumers and promote awareness. According to Mr Agrawal, “The Indian Government is taking initiatives along with the industry and corporate houses to encourage adoption of energy-efficient lighting solutions. Philips was also associated with the Bachat Lamp Yojana in Kerala, rolled out in 2010. Energy-efficient solutions for sustainability in buildings “Building energy efficiency is the first step toward achieving sustainability in buildings and organisations,” emphasises Mr Malhotra. “Improved energy efficiency in buildings, industrial processes and transportation could reduce the world’s energy needs in 2050 by one third and help control global emissions of greenhouse gases. The market for energy efficient technologies alone is valued at more than $1 trillion.” Green buildings have come a long way. Today they are looking at sunlight harvesting, and how daylight can be utilised and gaps can be filled with energy-efficient lighting systems. According to Mr Khurana, “There was a point when people were going for green building to earn carbon credits, which did not work out in the Indian context.” Carbon credit is losing its appeal;

Philips has a suit of energy-saving light products and solutions that reflect the best in energy-saving technology available today. While talking about Philips energy-saving products, Mr Agrawal describes, “Philips Dynalite system gives ultimate control and savings to buildings around the world. Philips Dynalite control solutions ensure lights are only used when needed, at a level that minimises energy consumption. It reduces the lighting levels temporarily in a subtle way to reduce peak energy demand and hence reduces electricity bills significantly.”
“Going forward, I would see companies like Havells optimising on their energyefficiency initiatives through more and more indigenising of production within India so much so that lighting companies would like to look at home grown LED chips in India as the cost has to come down because LED chips manufacturer would look at a long-term perspective here in television industry today, so they would look at the automotive lighting. So the mass is enough for companies to come forward and put an investment in India for manufacturing LED chips.”
Philips also offers GreenLED, which saves 50 per cent more energy compared to conventional CFL solutions. Mr Agrawal explains, “With modern product design, the LED lighting technology and reliable heat management delivers a long-lasting energy-efficient solution for offices and retails spaces. The lighting solution consumes only 15W of energy which is significantly lower than conventional 2X18W CFL down lighters (40W plus) and hence results in reduced operational costs.” Then comes GreenLEDi by Philips — a new offering for indoor lighting. GreenLEDi is an ideal value for money replacement for conventional solutions. According to Mr Agrawal, “GreenLEDi offer 50 per cent energy savings and has long life of 40,000-50,000 hours. These products have been specially customised to suit the lighting requirements of the Indian market.” Long-term perspective in lighting system India is displaying its awareness to promote lighting efficiency and power saving technology. Mr Khurana says, “India would see more investment by lighting companies in terms of indigenising lighting solutions. The future for utilities will definitely resort
For Philips, long-term perspective is to drive the switch to energy-efficient lighting solutions, i.e. LED products. As Mr Agrawal puts the spotlight, “LED lights are one of the most sustainable and long-lasting lighting sources available today. In the long run, benefits and savings of a LED light are much higher than the other light sources. LED lights also facilitate reduction in CO2 emissions, in addition to help save energy and maintenance costs.” Philips has a history to create innovative products and make a meaningful change to the lives of consumers. And that resonates in Mr Agrawal’s words, “By developing environment-friendly LED lighting products, Philips wants to signify how innovative solutions can bring a change in lives of consumers.” Even Mr Malhotra thinks so, “LED is wellknown as an energy saving and ecofriendly light source technology, and it is widely believed that these features will eventually make the LED the dominant technology in the lighting market. He adds, “There is a race among the LED manufacturers to produce more efficient products with higher lumen efficacy. I think in long terms, LED will become one of the most energyefficient technologies among all.”

Monitoring PV plants: reliable, easy
Siemens Energy has developed a solution that can be integrated into new and existing plants and monitoring systems, enabling even globally distributed PV plants to be managed centrally. Dr Eberhard Ritzhaupt-Kleissl explains.

ccording to a report issued by the European Photovoltaic Industry Association (EPIA) in March 2013, the previous year saw the world’s cumulative photovoltaic capacity breakthrough the 100 GW sound barrier. In 2012, almost one-third of this capacity — around 30 GW — was added by newly built PV installations, as stated in the EPIA report “Global Market Outlook for Photovoltaics 2013-2017”. Markets outside Europe were at the very forefront of this growth. This is particularly true of China, the USA and Japan, which together accounted for 8.5 GW of new PV capacity, although strong growth was also seen in India, Australia, Korea, Canada, Israel and Thailand. In terms of installed
Electrical & Power Review
GREEN ZONE capacity, however, Germany remains the leader, accounting for 32 GW or one-third of the world’s existing PV capacity. The total capacity attributable to Europe as a whole at the end of 2012 was 69 GW. In other words, the world has woken up to the advantages of generating electricity directly from sunlight. Experts are anticipating an annual growth rate of around 27 per cent between 2010 and 2020. As the proportion of total electricity generation accounted for by renewable energies increases, what the grid operators demand from the generators is also changing. In future, all power producers will have to play an active role in stabilising the grid, and the controllability of renewable energy generation will have to be improved. Grid operators require better forecasting of the energy that will be generated so that they can dispatch the individual producers to match the load profiles, which fluctuate from day to day. To this end, the volume of energy that will be generated must be as predictable as possible. This applies not just to the grid operators but — depending on
the grid code — especially to the plant operators. Furthermore, PV plants often need to be integrated reliably into existing generation fleets. Many PV monitoring systems currently available on the market do not meet these various criteria to the required extent and depth. Against this background, Siemens has developed a solution that not only satisfies these needs but also enables the efficient control and monitoring of photovoltaic plants. The Siemens PV Monitoring solution is based on the globally successful control system SPPA-T3000, which is implemented in more than 1,700 power plant units and has been adapted for use in renewable energies, including in particular small- and medium-sized PV parks.
Real-time monitoring of PV plants
Siemens solution. The field data from the individual containers is finished with a timestamp and forwarded to the central SPPA-T3000 application server. This second level controls the inverters and the grid parameters, the active and reactive power and the frequency. Any installed tracker systems can also be controlled via this server. At the same time, local key performance indicators (KPIs) and technical reports (performance ratio, generated energy volume, alarm messages, and so on) are calculated from the field data and made available here. At the third level, the Siemens Energy Asset Management (EAM) software SPPA-M3000 evaluates the plant data provided by the application server and, from this, calculates all the economic key figures and provides a yield forecast up to seven days in advance.
All process data of a PV plant, i.e. data from the PV modules or individual strings, the weather station, the switchgear, the fire detection system, the transformer, the ventilation system, and so on, is collected and forwarded to the local automation server. This fieldlevel forms the first level of a four-level pyramid that represents the entire
Such yield forecasts play a particularly important part in ensuring that the grid requirements are met in terms of the volumes of energy fed in. In preparing short-term and mediumterm yield forecasts, the Siemens solution considers current weather data as well as forecasts issued by

GREEN ZONE meteorological services, enabling it to provide each dispatcher with highly reliable specifications for grid feed-in and trading. Data is transferred from all PV plants monitored by Siemens via the Siemens Common Remote Service Platform (cRSP), a gateway that is secured and encrypted to current NERC standards. The data is archived on particularly secure servers in a data centre for at least 30 years, ensuring complete documentation and providing the basis for subsequent detailed fault analysis. The browserbased Siemens PV Portal represents the fourth level — the presentation level — of the PV monitoring solution. All previously calculated KPIs and trends are visualised here. At the touch of a button, the data from all PV plants can be displayed according to certain criteria (such as performance ratio, CO2 reduction and economic key figures). If several systems are connected to the PV Portal, customers can also compare their systems directly with one another using configurable reports. The Siemens PV Portal also enables direct access to all hardware elements of the monitored PV plants in real time via the secure gateway connection of the cRSP to perform remote maintenance on I&C and electrical system components. Just like conventional power plants, solar power plants must undergo continuous monitoring and regular maintenance in order to ensure continuously reliable operation. Faults must be identified as quickly as possible in order to avoid consequential damage and minimise any loss of yield. Furthermore, permanent monitoring is important in order to maximise the electricity yield from a PV plant. Dirt or shadows are the main causes of an electricity yield that falls significantly below the plant’s rated output. For this reason, regular cleaning of the modules is one of the most frequent PV plant maintenance tasks; failure to carry it out can cause yields to fall significantly, depending on the region.
44
May 2014
Optimum energy yield through continuous monitoring and regular maintenance In Germany, PV plants require less frequent cleaning as regular rainfall rinses the dirt from the solar panels. In other countries, however, climatic conditions often make it necessary to implement a rigorous cleaning program. In the United Arab Emirates, for example, sharp temperature fluctuations and the proximity to the ocean mean that maintenance of this kind must be performed every 14 days to remove the salt encrustations that can form rapidly on the modules. In other regions, vegetation must be removed regularly from underneath and around the modules to prevent it from casting a shadow. Thanks to accurate data collection and evaluation, the Siemens solution makes it possible to determine the optimum cleaning schedule for each individual plant or module, based on the most efficient ratio of cleaning cost to energy yield. Siemens offers flexible service packages to customers who do not wish to carry out all monitoring and maintenance activities themselves: from remote monitoring through to operation of the entire plant. Siemens offers a full-service package of this kind to customers who view their PV plants primarily as investments.
Future proof solution for PV plants with profound benefits The integrated Siemens PV monitoring solution offers operators of PV parks and fleets a range of advantages — demonstrated, for example, in projects
already completed in Israel (5 MWp) and South Africa (twice 50 MWp): • High reliability of I&C system and monitored electrical systems • Full compliance with all requirements of the electricity grid operators (grid code) • Option of integration into existing power generation fleets (fossil and renewable) and extendability of installed capacity or energy storage devices through implementation of a solution based on the marketleading control system SPPA-T3000 and EAM software SPPA-M3000 • Dependable predictability of the energy volume generated (up to seven days in advance) through precise data detection and evaluation, reliable operation, and consideration of meteorological information and complex forecast algorithms • Secure, encrypted data transfer and remote access to control and electrical systems via NERCcompliant gateways • Web-based PV portal with access to all information and KPIs, anytime and anywhere • Customer-specific service packages to maximise energy yield.

Ujaas Energy busy brightening REC mechanism
U
“REC mechanism is one of the best drafted, conceived ideas,” says Vikalp Mundra, Joint Managing Director, Ujaas Energy Ltd.
jaas Energy Ltd., established in Indore in 1979, is one of the first companies to install a solar power plant under Renewable Energy Certificate (REC) mechanism. The company has started setting up an innovative offering called as ‘UJAAS Park’ that provides complete plug-and-play solution to the investor for putting up a solar power plant at an affordable cost in time. In an exclusive email interview, Vikalp Mundra shares how REC is going to shape the future of solar power.
Ujaas has pioneered solar REC mechanism. How do you look at the solar REC mechanism in India? REC mechanism is one of the best drafted, conceived ideas. It makes a good business sense which give a much better return which is tax free and linked with power price which will only go northwards in coming years. The most important part is proper implementation of RPO regime, which can only create a liquid market for REC sale. In India any new concept took time, and the same is with REC. Further, power being a state subject, it moves with the political will power of the state.
How do you select a partner to execute an REC project? We commission REC projects in our park for our investors which are broadly of two categories: • Large Tax Payers: As a tax-planning initiative to claim benefit of
46

accelerated depreciation at 100 per cent. • HNI segment: They invest in power as an asset class in their portfolio of investments.
What are the tweaks required to make this concept more attractive? We propose following to make REC concept more attractive: • Periodicity of compliance: mandatory quarterly compliance of the RPO in place of annually. • Secondary trading: As REC is a market-linked mechanism, RECs must be made re-tradable, and this will pave way forward toward derivates and forward market. • REC floor price: Visibility to cover at least debt service period is desirable. • Re-packaging of floor price of solar RECs: With the decreasing solar tariffs since the present REC prices looks high there is a need to redefine the price of Solar RECs duly considering the protection of financial interest of plants installed previously which can be through the concept of vintage-based multiplier.
How much beneficial is your Ujaas Park concept? Ujaas Park gives two most significant unmatched advantages: • It gives economies of scale like big plants even to the owner of 0.5 MW plant. • Park is the only way by which a common man can fulfill his dream of owning a solar power plant.
Electrical & Power Review

JERC has announced strict compliance RPO for obligated entities in Goa and UTs. How do you view this initiative?
All the obligated entities are welcome to participate in REC trading in IEX and PXIL. We are willing to support in all ways as required and asked by OEs.
How big is your solar business now?
I wish to share with your readers that Ujaas being a leader in solar REC space, took onus to make RPO enforcement a reality. We are presenting the case to various regulators. This JERC order is also a result of our efforts. We all will see many such orders in coming time.
In India by March ’14, total installations will be 2,000 MW. Out of this, 350 MW is in REC space. Thus Ujaas is having about 5 per cent share in national market and nearly one-third share in REC space. It makes Ujaas as the largest umbrella in REC space.
What sort of support can you extend to obligated entities in the UTs to meet their RPO targets?
In FY14, you have targeted an ambitious 300 per cent growth from FY13 in terms
of installations. How did you perform? FY 2013-14 was a sluggish year for solar and all infra companies. Our results will be out very soon. I can share with you that Ujaas has performed very well in top line as well as bottom line in solar industry along with our peers in infra as a whole.
Can you brief on your long- and short-term objectives? Ujaas wishes to remain a leader, primarily in solar REC space with its park business. Ujaas is poised to take its mysite business very aggressively and would be looking to install at least 10 MW on rooftops in coming year.

on the grid, off the checkerboard A new insight into best arrangement of wind turbines on large installations 48

s wind farms grow in importance across the globe as sources of clean, renewable energy, one key consideration in their construction is their physical design – spacing and orienting individual turbines to maximize their efficiency and minimise any “wake effects”, where the swooping blades of one reduces
Electrical & Power Review
GREEN ZONE that turbines arrayed in checker board patterns produce the highest power output. Their study provides insight into factors that determine the most favourable positioning. This insight is important for wind project designers in the future to configure turbine farms for increased power output – especially in places with strong prevailing winds. “It’s important to consider these configurations in test cases,” said Richard Stevens, who conducted the research with Charles Meneveau and Dennice Gayme at JHU. “If turbines are built in a non-optimal arrangement, the amount of electricity produced would be less and so would the revenue of the wind farm.”
How wind farms are currently designed Many considerations go into the design of a wind farm. The most ideal turbine arrangement will differ depending on location. The specific topology of the landscape, whether hilly or flat, and the yearlong weather patterns at that site both dictate the specific designs. Political and social considerations may also factor in the choice of sites.

the energy in the wind available for the following turbine. Optimally spacing turbines allows them to capture more wind, produce more power and increase revenue for the farm. Knowing this, designers in the industry typically apply simple computer models to help determine the best arrangements of the turbines. This works well for small wind farms but
Electrical & Power Review
becomes less precise for larger windfarms where the wakes interact with one another and the overall effect is harder to predict. Now a team of researchers at Johns Hopkins University (JHU) has developed a new way to study wake effects that takes into account the airflow both within and around a wind farm and challenges the conventional belief
Common test cases to study windfarm behaviour are wind farms in which turbines are either installed in rows, which will be aligned against the prevailing winds, or in staggered, checkerboard-style blocks where each row of turbines is spaced to peek out between the gaps in the previous row. Staggered farms are generally preferred because they harvest more energy in a smaller footprint, but the new study showed that the checkerboard style can be improved in some cases. Specifically, better power output may be obtained through an “intermediate” staggering, where each row is imperfectly offset – like a checkerboard that has slipped slightly out of whack.

Siemens to market new distribution network management system for smart grids
T
he Siemens Smart Grid Division is introducing a new distribution network management system onto the market that has been specifically developed for building and expanding smart grids. Spectrum Power ADMS (Advanced Distribution Management System) combines SCADA (Supervisory Control and Data Acquisition), outage management, and fault and network analysis functions for the first time on a software platform under a common user interface. This simplifies all work processes and facilitates the entering and updating of data. The system also allows network operators to not only control and monitor their distribution network more reliably, but also carry out maintenance and repair work more efficiently. The new Siemens distribution network management system Spectrum Power ADMS (Advanced Distribution Management System) combines SCADA (Supervisory Control and Data Acquisition), outage management, and fault and network analysis functions for the first time on a software platform under a common user interface. “If new energy policies are to succeed, we need to make our distribution networks more intelligent. They must also be capable of being controlled efficiently as smart grids in order to effectively channel the increasing volume of electricity fed in from renewable energy resources. This is exactly what our new system allows power supply companies and utilities to do,” explained Jan Mrosik, CEO of Siemens Smart Grid Division. By suggesting actions to be taken and through automated processes,
50
May 2014
the system assists operators at the grid control centers in repairing and reconnecting the affected network section as quickly as possible after a fault. Another strength of the system is the intelligent use of smart meter data for fault detection and clearance and for controlling and monitoring distributed energy sources. This makes Spectrum Power ADMS a key component for building and expanding smart grids. Since it was developed for integration in a service-oriented architecture (SOA), the system can make use of services and data of other IT systems, such as cards and network data from geo information systems or load profiles from meter data management systems. In the same way, other IT systems can access services and data in the distribution network management system, like information for customer information systems about downtime in case of a malfunction, or work orders or switching jobs for the workforce management system. Thanks to its SOA design concept, Spectrum Power ADMS can be integrated efficiently in the user’s IT environment, thus allowing business processes to be optimized and work processes to be automated. The system provides the grid operator
with the right tools to comply with the requirements of current international reliability standards such as NERC CIP (North American Electric Reliability Corporation – Critical Infrastructure Protection) or those of the US federal agency NIST (National Institute of Standards and Technology). Interoperability standards such as IEC 61970 (CIM, Common Information Model) and IEC 61968 (system interfaces for distribution networks) have also been taken into account in the development of Spectrum Power ADMS in order to facilitate the IT integration of the system in an existing infrastructure. Energy-efficient, eco-friendly solutions for setting up intelligent power supply networks (Smart Grids) are is part of Siemens’ Environmental Portfolio. In fiscal 2012, revenue from the Portfolio totaled about 33 billion euros, making Siemens one of the world’s largest suppliers of eco-friendly technologies. In the same period, our products and solutions enabled customers to reduce their carbon dioxide (CO2) emissions by more than 330 million tons, an amount equal to the total annual CO2 emissions of Berlin, Delhi, Hong Kong, Istanbul, London, New York, Singapore and Tokyo.

After Borealis’ significant investment into a highly advanced high pressure low density polyethylene plant in Stenungsund, Sweden, inaugurated in
Electrical & Power Review
2010, Borealis is now investing in an XLPE capacity increase at the Stenungsund plant. This investment, which increases overall capacity by 20 kilotonnes, is being applied directly to Borlink extra high voltage (EHV), high voltage direct current (HVDC) and high voltage (HV) polyethylene compounds produced in closed or controlled loop processes. Borouge is currently expanding its polyethylene (PE) and polypropylene (PP) manufacturing capacity in Ruwais, Abu Dhabi, from 2 million to 4.5 million tonnes per year (t/y). This development is one of the largest and most integrated polyolefin expansions in the history of the petrochemical industry and is positioning Borouge among the top producers in the Middle East.
The wire and cable industry will reap the concrete benefits of this growth with relevant grades produced at a 350,000 t/y high pressure, low density polyethylene (LDPE) plant, a significant addition similar to Borealis’ LDPE plant in Sweden. “The present Borouge development enables our customers in the Middle East and Asia in particular to benefit from the great product performance and high productivity levels delivered by our super clean XLPE compounds as well as the reactor-made Visico XLPE base resin. This will also allow our customers to be served regionally by our Ruwaisproduced Borlink XLPE compounds,” says Roland Janssen, Borouge Vice President Marketing Centre Wire and Cable.
