(India) Tel.: +91-22-32682214 / 15 GROUP EDITOR* Subhajit Roy Email: editor@eprmagazine.com EDITORIAL Dibyendu RoyChowdhury Shahzad Bagwan ADVERTISING Sanjay Poojary Email: sanjay@i-techmedia.com Call: +91-9975097047 SUBSCRIPTION subscribe@eprmagazine.com Telephone: +91-22-3268 2214/15 *responsible for selection of news under PRB Act

As far as power sector is concerned, inclusion of renewables within the PSL is expected to widen opportunities. Under the renewable energy segment, bank loans of up to ` 15 crore for solar-based power generators, biomass-based power generators, wind mills, micro-hydel plants and for non-conventional energy-based public utilities like street lighting systems and remote village electrification will be considered as an integral part of PSL. For individual households, the loan limit will be ` 10 lakh per borrower.

Welcoming this move, Suzlon Group Chairman Tulsi Tanti said it will help contribute to India’s renewable energy portfolio and achieve energy security. He adds, “The notification by RBI will boost investments from the SME sector in renewable space as the finance will be available at a competitive rate as the bankers have separate allocation and priority for the sector.”

Furthermore, he believes, the move will help SMEs grow and expand their manufacturing capacity in a larger way, as they will become competitive because of low cost of energy for the next 25 years and achieve availability of energy for captive use. “The reinstatement of accelerated depreciation and other policy impetus are a testament of the government’s progressive outlook and clear vision to achieve energy independence of the nation,” he adds.

Shekhar Dutt, Director General, Solar Power Developers Association (SPDA), has termed the new RBI guidelines as an “encouraging step forward for the renewable sector players.”

Whereas Vineet Mittal, President, SPDA, believes that the new norms will boost credit and in turn will benefit the developers hugely, as it will make the fund-lending framework less stringent and more flexible.

While these guidelines, however, will boost the growth of the industry, the industry believes that there is a need for additional inflow of funds to finance large-scale projects in the country, and the industry is looking forward to these developments.

GVK’s 330 MW Alaknanda Hydropower project synchronised

Emerson automates 800-MW supercritical power-gen unit

The first Unit of GVK’s 330 MW Alaknanda Hydro Power Company Ltd.’s project at Shrinagar in Uttarakhand, was successfully synchronised with the Northern Grid on April, and tested to generate the full rated capacity of 82.5 MW. Post that, some operational tests were also successfully conducted.

Emerson Process Management has completed automating a new 800-megawatt; supercritical thermal power-generating unit owned

by APPDCL, a special purpose entity of APGENCO, the Andhra Pradesh state government power generation utility. This is the first stateowned supercritical power station being built in India. Located in Krishnapatnam, the Sri Damodaram Sanjeevaiah Thermal Power Station is a US$ 2 billion investment by APGENCO that will provide new, lowemissions generation capacity to support the region’s rapid economic growth.

A thorough inspection of the machine shall now be carried out before starting commercial production. The remaining three units will be sequentially synchronised by the end of June, and full-fledged operations will commence soon after.

GVK’s 330 MW hydropower project consists of four units of 82.5 MW each, and is situated on the river Alaknanda at Shrinagar in Tehri / PauriGarhwal, Uttarakhand. The unique feature of this project is that it has a 90 m high dam (from the deepest foundation level). Besides gainful employment to locals, the project will provide clean energy through the Northern Grid.

Tata Power offers online application for power supply Tata Power has launched the online application facility for power supply.

The unique feature under this facility is that it enables an individual to apply for power supply at the convenience of his fingertips. Consumers can directly fill in their relevant details and upload their self-attested supporting documents well within 10 minutes. Moreover, consumers can also track the status of their application through the company’s website. The facility is integrated with the company’s customer website.

The new power station uses supercritical boiler/turbine technology that operates at higher temperatures than traditional coal-fired units, boosting the efficiency of electricity generation while reducing carbon and other emissions. Emerson’s automation technology has been selected for more than 300 of these complex units worldwide, 10 of which are located in India.

Emerson was selected as the main automation contractor by Tata Projects Ltd., the engineering, procurement and construction (EPC) contractor for critical sections of the plant. The first unit at Sri Damodaram Sanjeevaiah is ready to begin commercial operations; Emerson is currently automating the second unit at the site, which is expected to be completed this spring.

At the new unit, Emerson’s Ovation distributed control system monitors and controls plant equipment and processes including the boiler, water treatment system and other critical balance-of-plant processes.

Emerson also installed its Rosemount® measurement and analytical technologies to monitor sections of the plant for optimal performance.

Making India manufacturing hub difficult yet achievable “We have to be competitive for growth globally as well as look at ways and means to draw in more investment into the country,” says Vishnu Agarwal, President, IEEMA Indian Electrical and Electronics Manufacturers’ Association (IEEMA) is the apex industry association of electricals and industrial electronics in India. The association is actively involved in addressing the bottleneck issues at all levels. In an exclusive interview with EPR, Vishnu Agarwal talks about the electrical equipment market and how to make it self-sustained.

How are policies and initiatives by the new government affecting the electrical equipment market?

The size of the Indian electrical industry is valued at around $28 billion; a fourth of it is made up of power generation equipment.

Transmission and distribution is contributing the rest. The industry provides direct employment to about 500,000 people and indirectly to about 1 million. We, as a country, are aspiring to increase the output of the electrical equipment industry to $100 billion by 2022 and become a destination of choice for overseas producers of such equipment.

This ambitious target can not happen without the active support from the government through investment-friendly policies and by focussed efforts of industry. We have to be competitive for growth globally as well as look at ways and means to draw in more investment into the country.

The new government looks very serious about the above and various initiatives such as “Make in India” campaign and skill-development initiatives are being pursued extensively. In

order to unlock the power sector growth, which is battling fuel shortages and problems of land acquisition and securing mandatory approvals and suffering from several stalled projects, would be a topmost priority. A lot of actions in all directions are being taken with right earnest at that level.

Imports have captured about 43 per cent of the market for electrical equipment in India. Is it a matter of serious concern? If yes, how should we address this?

The time between 2011 and 2013 has been extremely volatile for the Indian electrical equipment industry which showed a positive growth curve of 9 per cent in the first half ( H1) of 2011-2012. However, this was followed by a decline to 4.14 per cent in the second quarter (Q2) of the year from 13.82 per cent in the first quarter (Q1) of that year. Such inconsistency in the performance of the industry can be attributed to a number of factors. One of the main factors had been inflow of huge imports. Imports have grown by nearly 20 per cent from China, South Korea, Germany and other EU countries.

This significant influx in imports had seriously damaged the indigenous electrical equipment industry. There has been a significant hike in the price of the imported raw materials which were making the finish product as uncompetitive and seriously bleeding the domestic industry.

China’s share in Indian imports of electrical equipment has dramatically increased in the last few years and stands at 44.92 per cent of the total in 2012-13, from 15.26 per cent in 2005-06. Data show that imports from China have grown at a CAGR of 24.67 per cent in the past 7 years. Imports of electrical equipment have assumed very threatening proportions and have now captured a 38.26 per cent market share of electrical equipment in India, whereas there is significant under-utilisation of installed domestic capacity, resulting in loss of employment .

Electrical & Power Review

EPR PERSONALITY In order to stimulate demand for the domestic electrical equipment industry, we think the government should provide a level-playing field for Indian manufacturers to compete with imported equipment in the domestic market. There is an urgent need to improve fund availability to the power sector and provide fuel linkages and faster regulatory clearances for timely completion of power projects.

Model procurement guidelines for utilities with standardised and fair contract terms and conditions should be framed. Due importance should be given to the entire lifecycle cost of a product while evaluating the bids. Opportunities for new domestic manufacturers should be given by reforming the tendering process to increase transparency and speed.

How is IEEMA helping the Indian electrical equipment market in addressing growing challenges?

Indian Electrical and Electronics Manufacturers’ Association (IEEMA), being the APEX industry association of electricals and industrial electronics in India, is actively involved in addressing the bottleneck issues at all levels. It is in constant dialogues with the policy makers for ensuring the level playing fiels for the domestic industry. It has been highlighting the issue of price volatility and availability CRGO steel, which is totally imported and a critical raw material for all types of transformers .

IEEMA ‘s different product groups keep meeting at regular intervals to review the progress on the resolution of pending issues and identifying the new areas where the apex body has to work upon and can contribute .

In order to showcase the technological achievements of Indian electrical industry to oversea customers, IEEMA organises ELECRAMA exhibition every alternate year in Bengaluru. This exhibition is one of the massive shows and gives plateform to the all the Indian and overseas stakeholders to interact and get benefitted.

IEEMA ‘s different product groups keep meeting at regular intervals to review the progress on the resolution of pending issues and identifying the new areas where the apex body has to work upon. We also organise various technical workshops related to different product groups to share the technological improvements and latest engineering and technological advances in the respective fields .

What actions should be taken to enhance competitiveness within the domestic electrical equipment manufacturing sector?

While it is an acknowledged fact that increase import of electrical goods has put the domestic industry at the brink of vulnerability, yet it is an opportunity for domestic industry to do serious introspection as well.

Electrical & Power Review

Strategies for competitiveness for India has become need of the hour. Our country experienced controlled economy till 1990 and then liberised one. Lowering the tariff barriers in domestic market has unleashed growing competition. This situation forced the domestic market to become competitive to earn sufficient foreign exchange to pay off our import requirements. Only way we can stay afloat is by creating competitive edge.

We, therefore, should seriously think as to how can we create competitive edge over the global players in terms of technology, product quality, process innovation, value engineering and so on. Acquiring customers and access the markets, which constitute future profitable growth from anywhere on the globe, call for enhancing competitiveness.

A major precondition for competitiveness enhancement is the availability of skilled labour.

The constant changing conditions of international markets forces the stiff conditions that the nations has to face.

Therefor innovation is key to the competitive advantages for the country.

Technology advances help lower the cost and risk levels, thereby reducing the manufacturing capital requirements. Therefore, the organisations have to be the learning organisations to have the sustainable competitive edge. Increased spending in R&D will help develop cost-effective technologies.

The Indian Electrical Equipment Industry Mission Plan 20122022 has planned to make India the country of choice for the production of electrical equipment and reach an output of $100 billion by balancing exports and imports. According to you, what should be right approach to achieve this mission?

In order to accomplish the set target of $100 billion by 2022, a comprehensive short-term and long-term strategy will have to be evolved and goals have to be set and achieved. The task is difficult but not unachievable.

From policy and law makers side, it will call for a strong forward looking political will, ensuring political stability and coming up with investment-friendly policy decisions and their fast implementation, addressing the issues that are bugging power sector. Higher budgetary spending in capital expenditures in infrastructurerelated projects will be essential to support the growth.

Industry has to focus on project innovation and superior product quality. We, Indians, spend lot of resources in research; however, there is not much focus on development. Superior manufacturing and process technologies need to be harnessed for cost reduction and becoming competitive.

Skill development has to be taken with right earnest. Our products have to be globally accepted for their quality and value for the money. mAy 2015

The global electrical equipment market is expected to increase from a cumulative size of more than $3 trillion (2008-15) to $ 6.8 trillion (2016-30). There has been an overall growth in most segments of the electrical equipment industry — transformers, power cables, switchgear — due to the high demand from central and state power utilities.

Over the past couple of decades, power planning had a great setback and accomplished not more than 50 per cent of the target. With the installation of the new government, the industry is hoping for the better, as tangible progress in getting clearances of various power projects have been observed.

We need to seize the opportunities ahead to leverage our resources to create wealth and prosperity for generations to come.

We need to work with vision that creates lasting prosperity instead of feeding an endless cycle of boom and bust.

According to J K Agarwal, Joint MD, Genus Power Infrastructures Ltd., “The Mission 2012-2022 will establish a clear roadmap for increasing the competitiveness of the domestic electrical equipment sector.

It is also needed to focus on the next generation of reforms in the power sector, specifically the power transmission and distribution sector.”

The government should take a holistic approach as the power sector is critical for the socio-economic development of the nation, as well as the industry needs to upscale the size of its operations and manufacture quality products at the most affordable prices so that the buyers from International market can be attracted.

“In order to achieve this ambitious target, we have to see how far the government is able to implement the industry friendly policy,” says Anil Krishna, Vice President, Borouge (India) Pvt. Ltd. “Starting from making land and infrastructure available for industry to be set up, single window clearances, labour law reforms, taxation policy all needs to be updated to meet global competition. In a democratic country like India, implementation and execution is always a challenge.”

It won’t be surprising to see phenomenal changes on the product side driven by emergence of disruptive innovations like fuel cells and choice of fuels for power generation considering latest trend of oil economy. No wonder the government has prepared a very comprehensive mission plan for the industry and have touched upon all the aspects. It is the monitoring of extent and speed of implementation of recommendations that will ensure the success.

Then there is innovation which plays a big role in achieving exports target of

$23 billion by 2022 as we must get first mover advantage to reap benefits in this competitive industry. The government should also support or rather subsidise innovation in power sector to make the Indian power industry a super success story.

Domestic versus foreign equipment Indian equipment manufacturers not only cater to the domestic demand but also export to several developed and developing nations. According to Vimal Kejriwal, Managing Director and CEO, KEC International, “There is a positive outlook and acceptance towards Indian manufactured equipment by countries across the globe. Around 55-60 per cent of our order book consistently comes from foreign markets.”

With continuous progress being done on the quality front, India churns products that are well placed globally. Generally, the Indian manufacturers follow IEC standards as well as whenever required conform to US and Canada — ANSI, NEMA, IEEE, UL and other standards.

Industry needs to understand that either your customers come back or products come back. Mr Rajendrakumar explains, “The demand of any origin equipment or product is governed by commitment to understand, meet and when possible exceed customers’ requirements at ethically best price for said performance and after-sales service backup.

“The market is further anticipated to witness sound healthy growth rates and empowering demand for the impending years,” believes Anil Kadam, Senior Manager - Solution Architect (Utility Segment), Schneider Electric India. “The government initiatives alongside the need of substitution of transformers introduced in the previous years are relied upon to drive development in the Indian transformers market. Schneider Electric India is a well-established manufacturer having capabilities to develop all type of transformers up to the 800 kV and 1,200 kV levels.”

Transformer industry is completely geared up with latest innovations and technologies for manufacture of transformer of highest ratings, i.e. 1,500 MVA at 765 KV voltage class. The industry is capable of catering the demand or requirement of domestic market besides 50 per cent of the export requirements.

Switchgear market getting turned on Increasing investment in manufacturing segment as well as urban and rural

The switchgear market overall has seen a tapered growth for past 2-3 years due to adverse macroeconomic scenario.

infrastructure development have turned on the switchgear industry for the better.

The switchgear and control gear industry in India is currently valued at ` 135 billion in FY 2013 and has been growing at 15 per cent for the past 3 years. It is estimated that the industry is going to touch about ` 215 billion by FY 2017, growing at a diminished CAGR of 10 per cent.

India is the world’s sixth largest energy consumer, accounting for 3.4 per cent of global energy consumption, and the nation is witnessing increased investments in the manufacturing segment as well as urban and rural infrastructure development all over the country.

According to AV Jagdish, Vice President, Switchgear Division, Havells India Ltd., “The switchgear market overall has seen a tapered growth for past 2-3 years due to adverse macro-economic scenario.

With a stable government with focused plan to improve Indian economy and its new investment plans in infrastructure development, the market looks determined to reinvigorate growth.”

The per capita total energy consumption in India was 917.2 KWh by March 2013.

Due to India’s economic rise, the demand for electrical energy has touched great heights. The per capita total energy consumption is now expected to grow to 1,200 KWh by 2016. “With the rapid increase in urbanisation, new residential and commercial complexes, there is a high demand for electrical switchgears,” says Rajesh Nandwani, Business Unit Head - Switchgear, Anchor Electricals Pvt. Ltd. “The low-voltage switchgear market size in India is about ` 11,000 crore. The domestic switchgear market is about ` 2,200 crore which includes products like MCB, RCCB and DB.” The need to have a safe, reliable and efficient power distribution setup at both micro and macro levels is providing growth opportunities to the lowvoltage (LV) and medium-voltage (MV) switchgear markets in India.

The market is further anticipated to witness sound healthy growth rates and empowering demand for the impending years

Powerful power cables market The new government, the new policies, the “Make In India’ initiative, and a mission to make India the choice for the production of electrical equipment and reach an output of $100 billion by balancing exports and imports, the wires and cables market is in a such position from where success is just a step away.

“Wire and cable business growth is linked to power and infrastructure segment growth,” remarks Mr Krishna.

“With auctioning of coal blocks to power producers, the sector is likely to show double digit growth for next 3-4 years.”

However, large part growth across manufacturing and infrastructure sector has been subdued. Market sentiments have improved largely due to falling commodity prices but are yet to see a turnaround. At the same time, the government has promised investment in railways, ports, smart cities renewable generation and distribution amongst others. This bodes well for cables market, and the industry can expect it to grow annually at 10-12 per cent.

If the government succeeds to facilitate infrastructure creation, promote capabilities, create a favourable and predictable business environment, attract investments, and promote R&D, the power equipment industry will show a major turnaround in growth.

“India can change the global economics of smart grids” “We want to bring our global experience to the Indian market, but we also expect to learn a lot from India in return,” remarks Adam Welsh, Senior Director, Regulatory Affairs, Asia-Pacific, Opower Opower is a publicly held Software-asa-Service (SaaS) company that provides cloud-based software to the utility industry and transforms the way utilities relate to their customers. In an exclusive interview with Subhajit Roy, Adam Welsh shares the importance of smart grids and how Opower programmes help customer engagement.

What makes you venture into the Indian market?

Our programmes are most effective when they are deployed across a lot of households.

We take metered energy consumption data combined with other data sets such as weather, demographic and housing stock, and send practical, timely insights to utility customers in a compelling format, that helps them manage their energy consumption and encourages them to take action to save energy or reduce energy at peak times. We focus on residential energy use, so when we think about India, you don’t get a scale bigger than India. We don’t need smart meters to be successful, although the more data we can access, the greater impact we can have.

Currently we partner with nearly 100 utility companies around the world, with around a third of those deploying smart meters to some or all of their customers. The rest just use monthly metering, and we run successful programmes with them. We feel that prior to the smart meter rollout there is a lot of opportunity in India to engage with utility providers here: to lower operational costs, lower CO2 emissions and lower peak demand.

Once smart meters are actually rolled out, we feel that India has the potential to change the global economics of smart grids.

Are you eyeing to setup a business unit in India?

We are really interested in working with utilities in India. We feel that there is a lot of potential for Indian utilities in our programmes. The basic structure of our programmes is to be cost-effective and positive in terms of benefits for utility companies, but importantly for their customers too.

What are your key objectives for Indian market?

We believe there is a significant opportunity for demand-side management here in India.

We are the world leader in behavioural demand side management at the residential level. Our programmes are also effective in low income areas which we think would be helpful in India. There is also significant benefit in engaging utility customers, our programmes help to drive online engagement, which reduces the cost to serve each customer for ‘everyday’ needs and allows the utility to focus its efforts on value-added services. .

Our company was founded in order to improve energy efficiency, eight years ago in California. In recent years, our experience in energy efficiency has enabled us to develop expertise in customer engagement and today we are the global leader in cloudElectrical & Power Review

based software for the utility industry, transforming the way utilities engage with their customers.

More recently we have been experimenting in behavioural demand response around key peak moments, such as hot summer days or cold winter days. We have now run very successful behavioural demand programmes in the United States, that without financial incentive, have reduced residential consumer demand by as much as 5 per cent per cent – it’s a really exciting programme. Opower’s customer engagement platform enables utilities to reach their customers at moments that matter through proactive and digitised communications that drive energy savings, increase customer engagement and satisfaction, and lower customer operation costs.

Opower’s software has been deployed to more than 95 utility partners around the world and reaches more than 55 million households and businesses. We want to bring our global experience to the Indian market and we also expect to learn a lot from India. We have been lucky that we have worked with innovative utilities which push us to develop in new areas. We developed unusual usage alerts for Mercury Energy in New Zealand where we send messages to alert people if they are tracking towards a higher than usual bill, so that they can take action to get back on track. This kind of proactive helpful communication achieves several things: it improves customer satisfaction as customers and it lowers call volumes by as much as 19 per cent per cent for high bill complaint calls. So it’s less expensive to serve your customers when you get less call and you have happier customers – it’s a win-win.

When can we expect Opower in the India market?

Typically we begin our programmes with a pilot phase, so the first step is to establish a pilot with a utility partner here.

We are talking to a number of potential utility partners here in India and we hope to establish a pilot this year. Opower has an extensive localisation programme, which is one of the reasons why it typically takes at least 12 months to launch a full programme. When I say localise what I mean is that we don’t just localise in terms of the local language, to ensure our programmes have the greatest impact we also localise the energy tips that are incorporated into the programme – so that consumers receive actionable tips that are relevant to them and their situation, taking into consideration their energy consumption, their household etc.

We will be working with local partners to support this process.

Typically, the minimum size of a pilot programme is around 20,000 to 50,000 households. Once we start expanding our programme across larger populations we are also able to segment different groups which enable even more impactful interaction and engagement. Our programmes do not rely on in-house devices or other hardware, so the cost to serve each household is low. It is the cost of sending either the paper mail or email or message alerts. It is very low cost for traditional households.

High-efficiency distribution transformers High-efficiency transformers create economic benefits for the society. Besides reduced greenhouse gas emissions, they improve reliability and give potentially longer service life by bringing down temperature rises through energyefficiency improvements. India has, by now, adopted the international IEC standards as well as introduced star labelling for selected categories of transformers.

According to Leonardo Energy Transformers Report, 2005, the global transmission and distribution network losses will lead to global economic loss of more than $61 billion annually and annual greenhouse gas emissions of more than 700 million tonnes. It is estimated that one-third of network losses occur in transformers, and of these transformer losses, 70 per cent occur in distribution transformers. The report estimates that the total electricity lost on utility networks around the world in 2005 was about 1,279 TWh, and of that, distribution transformers consumed 298.4 TWh. Most power losses occur in the transformer core made up of magnetic

ensuring realisation of national benefits of cost-effective energy.

Copper reduces load loss, because it is a more efficient conductor. By reducing load loss, Copper wound transformers helps increase profit margins of power distribution companies. Besides, the smaller size of copper transformers saves core steel as well as structural elements, including the tank, oil, cooling equipment and other accessories. And copper being stronger than aluminium, the former withstands stresses better than aluminium, thus, extending the transformer’s life and reducing lifecycle maintenance costs.

The relevant Indian standard for distribution transformers (DTs) IS:1180/1989 has been revised in the year 2014 as IS:1180 (Part1)/2014 by Bureau of Indian Standard (BIS) thereby superseding IS:1180 (Part 1 and 2)/1989 both for sealed and non-sealed type. In the revised version, the losses at 50 per cent and 100 per cent loading have been incorporated and the scope of the standard has been extended from 100 KVA to 2,500 KVA three-phase and single phase up to 25 KVA rating, at voltage (11 to 33 KV) have also been included to make it a comprehensive standard on DTs.

The market size for transformers in 2013 was at 2,66,000 MVA in India and has seen an annual growth of 17 per cent year on year. The target for capacity addition during the 12th Five-Year Plan is 88,000 MW. Promotion of energy-efficient transformers through a number of policy instruments, including Minimum Energy Performance Standards (MEPS), are the most powerful tools to shift the entire market to higher levels of efficiency and

This standard further recommends multiple grading with regard to energy efficiency, i.e. three energy-efficiency levels: level 1, level 2 and level 3 of transformers corresponding to 3 star, 4 star and 5 star labelled transformers respectively, as prescribed by BEE (also as per CEA mandatory guidelines). It is, therefore, necessary that DTs will conform to IS1180 (Part 1):2014, which is the Indian Standard under mandatory certification for relevant energy-efficiency levels. More so, the DTs Electrical & Power Review

Also, India has adopted a mandatory labelling scheme launched by Bureau of Energy Efficiency (BEE) for specific types of liquid-filled, naturally air-cooled threephase distribution transformers. It covers power ratings up to 200 kVA. Power utilities were mandated to procure at least a 3-starred distribution transformer.

BEE is in the process of reviewing and enhancing the scope up to 2,500 kVA.

specifications mentioned in the national standards. Power utilities may be initially paying more upfront for purchasing high-efficiency transformers, but lower losses of electricity across their life span lead to a higher return on investment.

ICA India through its programme’s creates awareness among utilities, particularly on EE, reliability and quality of distribution transformers, and testing services from ERDA and CPRI. The association creates platforms for interaction of all the stakeholders to create a major thrust for market transformation towards EE and enlightening users about the benefits of life-cycle costing versus preference for lowest bid adopted at present, particularly when the cost of energy losses, failure risk and maintenance into account, as well as the investment cost and residual value of the transformer at retirement are taken into account.

Automating LV distribution networks using sensor technologies This article analyses the various applications of sensors in LV distribution network automation and the way they are revolutionising the development of smart grids using real time information and data analytics, and contributing to environmental benefits In today’s competitive environment, there is an increased pressure on the distribution network operators to manage the state of the networks in real time to ensure reliable services.

The regulators have enforced stringent guidelines and performance benchmarks (such as CAIDI, CAIFI, CI and CML), and there are heavy penalties for not adhering to these standards. This combined with the growing awareness of the customers of their rights to demand better services under the new electricity regulations have driven the distribution utilities to introduce innovative ways of managing their networks more efficiently and effectively. As a result, sensor-based technologies have assumed significance in managing low voltage networks down to the last mile.

Some of the key application where sensor based technologies are being used by the utilities for improving operations, revenues and energy efficiency are: • Asset management system • Transformer monitoring system

• Fault management and service restoration • Real time network analysis • Power quality monitoring • Peak load management • Automated demand response.

Asset management system One of the main challenges of the distribution utilities is track their network assets throughout the life cycle, in order to manage assets costs with greater efficiency and higher profitability. Utilities are exploring new technologies for precise inventory control, with the ability to manage, track and secure critical assets in real-time, as part of the strategy.

The most commonly used technology is the “wireless” tracking devices.

Tiny wireless RFID (radio frequency identification) tags can be placed on a network asset such as distribution transformer or smart meter. These RFID devices communicate with the intelligent asset management system, which helps the utilities in asset planning, deployment, tracking and optimisation.

The active RFID tags are attached to assets which are to be tracked or monitored. These tags communicate with RF sensors strategically located near the assets and linked via wireless repeaters or a data communication bus to the asset management application, which then displays the real-time location of the tagged assets. The complete history of an asset or its movement is logged by the system through the use of active asset tags.

Guest Column health of the Distribution transformer has to be monitored at all times to ensure continuous and reliable supply of electricity services. Introduction of sensors for on-line monitoring of key operating parameters reduces the risk of transformer failure and cuts maintenance costs.

The parameters which can be monitored on a Distribution transformer are: • Surface temperature • Winding temperature KW

• Transformer oil level • Oil temperature • Gas and moisture in transformer oil.

Monitoring of the above parameters involves on-line collection of data using sensor based measurements and transmitting the data to the remote monitoring application through suitable communication systems e.g. RF or ZigBee communication. The failures of transformers in service are broadly Peak demand Peak demand rescheduled to keep it below a given threshold Reduced peak demand

Time

due to temperature rise, low oil levels, over load, poor quality of connections or improper installation.

Monitoring sensor data of distribution transformer for critical parameters of surface temperature, low oil level and over load could be utilised to take proactive action in fault prevention, thus increasing the reliability of distribution network.

Fault management and service restoration Fault passage current sensors on LV distribution systems can measure the current flow in real time and help in the early detection of overloading, short circuit or earth fault. The current signals can be graphically displayed on a remote Digital Fault Recorder (DFR) and the information could be utilised to validate the location of possible fault occurrence. Early detection of an impending fault can provide operators with a better understanding of the vulnerable sections of the network and

Guest Column the maintenance crew can be dispatched to reinforce those sections before a catastrophic fault may occur.

There is increased pressure from regulators and customers to reduce the number and duration of outages.

Imposition of stiff penalties on utilities for poor network performance is incentivising the use of sensors for better management of power distribution system, early fault detection and preempting power outages. Utilities are therefore considering deployment of current sensors (Rogowski Coils, Hall Effect sensors) for better fault management and achieving regulatory targets of network performance through: • Quicker detection of a fault condition • Accurately determining the location of fault • Isolating of the faulty section of the LV network • Re-energising healthy sections – upstream and downstream - outside the isolated faulty section.

Any abnormal data from the sensors are analysed and used to isolate the faulty sections and switch to alternate network plans to minimise the impact of power disruption and facilitate early restoration of services in case of a fault. The sensor data help in optimal design of the switching plans of LV networks, considering all network constraints, system interlocks, protective devices and safety issues, and facilitate early restoration of services to a large part of the network and customers, without overloading.

Real time network analysis Earlier, for traditional distribution networks without sensor-backed automation, utilities had to rely on customer calls to be aware of network outages. Now Supervisory control and data acquisition (SCADA) at the substation get regular data from remote sensors via remote terminal units (RTUs) in real time, which is analysed to know the state of the networks.

Sensor-based technologies have made predictive analysis possible on the electrical networks which helps in network fault prevention, optimisation and planning. With real time analysis, it is possible to detect sudden sags or swells in feeder voltages and current, any abnormal load variations or physical conditions. Integrated with Transformer monitoring system, outage management system and electrical protection systems, real time analytics can help estimate the current state of the network and identify the characteristics which might need immediate attention to prevent major failures.

The intelligent Distribution Management System (DMS) rely on sensor data for real-time modelling of the distribution network. Signals from the fault sensors, help the DMS perform real time analytics to operate the protective devices in a coordinated manner to isolate the faulty sections and restore the network through alternate switching plans, in a safe and reliable manner.

Power quality monitoring The quality of electrical power is an issue of increasing concern for

RF communication

industry players. The power quality of an electrical distribution network is affected by power line disturbance such as wave shape faults, overloading, capacitor switching transients, impulse transients or harmonic distortions. The rapid proliferation of energy efficient equipment, renewable energy sources and power electronics is increasing the presence of harmonics in the electrical supply. This can often damage circuits and equipment, by overheating and failure, or by the inefficient use of increasingly expensive energy. Ideally, the best electrical supply would be a sinusoidal waveform of a constant magnitude and frequency. However, many loads are not purely resistive and the presence of magnetising current, effect of rectification and inherent impedance of certain loads may result in creation of harmonics or transients, which may degrade the power quality and cause technical losses.

Various measurement instruments of smart grids e.g. smart meters, protection relays and fault recorders may not measure all the power quality parameters. By using appropriate sensors and telemetry systems, it is possible to monitor power quality problems at regular intervals and analyse these data to reduce their effects, thus making the electrical network trouble free and more efficient. These sensors allow distribution network operators and high electrical load consumers to record vital information regarding power quality.

Guest Column identification of specific sources of harmonics. Each sensor unit measures and records harmonic and interharmonic frequencies, present on the main electricity supply at specific locations. The recorded data is then periodically transmitted through a wireless or wired communications network to a centralised database, where the information can be analysed and stored. The low cost of each sensor, combined with the convenience of wireless communication, enables monitoring electrical power quality at multiple locations of the network.

This method significantly reduces costs by eliminating expensive diagnostic instrumentation, such as power quality analysers.

The sensor platform incorporates data management and visualisation software, which allows maintenance and operation personnel to use it for power quality measurements and analysis.

Peak load management Sensors are transforming the operation of LV networks in combination with information and communication technologies (ICT) to build intelligence into the network for peak load management. Modern applications in energy generation, power distribution and energy consumption use sensors to make efficient use of green energy, increase automation in distribution and enable peak load management.

Interconnecting consumer devices with the home area networks, and at the same time, communication with the utility networks through a home gateway facilitate residential energy management.

Residential energy management uses utility-driven price signals which vary depending on the time of the day, called Time of Use (ToU) pricing. In TOU pricing, electricity consumption during peak hours costs more than electricity consumption during off-peak hours. In peak hours, demands of the consumers rise, and utilities are compelled to deploy spinning reserves at a higher cost of Electrical & Power Review

energy and environment. Reducing peak load decreases the expenses for energy generation with corresponding decrease in greenhouse emissions.

Wireless sensors can play a key role in sensing the growth in energy demand and prompting actions to control this demand during peak hours. Intelligent electronic appliances fitted with sensors can communicate with the electric grid in real time to switch off or defer operation to cheaper off-peak hours, thus helping in energy balancing during peak loads. Another faster and reliable way of managing peak loads and balancing demands is through automated demand response.

Automated demand response Automated demand response refers to a smart grid device or application interacting with customers to influence their consumption of electricity or their load demand during select time periods. This signals customers to decide to lower their consumption or shed electricity during peak periods, and shift their demand to off-peak periods to save energy costs. Utilities use automated demand response to achieve a balance between electricity generation and electricity consumption, thus helping in load optimisation and grid stability.

Traditionally demand response interactions were manual, but with the introduction of sensors and advanced control systems, the LV network interacts directly with its customers’ load control systems to manage peak loads and balance consumption.

Automated demand response combines the inherent benefits of automation to bring more reliable, faster and cheaper responses to the load demand signals.

Automated demand response requires both the grid and the demand-side entities to install infrastructure to support the exchange of signals. The grid entity puts in place sensors capable of communicating demand response signals to their customer’s automation

equipment and the customer installs equipment capable of receiving these signals. Further, the demand response signals are relayed to the control systems where demand response strategies have been pre-programmed to execute the appropriate load control.

Depending on the type of customer facility, such control systems could be as simple as a thermostat in a residence or as sophisticated as an industrial process control system. The smart network will receive feedback of the demand response signal on the facility’s consumption via a smart meter or the control system.

With automated demand response, the customer can respond to smart meter or sensor signals indicative of desired levels of demand response as opposed to manual load control. Automated demand response represents a way for distribution network operators to avail of more demand-side resources as a cheaper option for grid balancing.

Conclusion The assessment studies on the impact of sensor technology on LV distribution networks reveal that the technology has a high potential in improving operational efficiencies through proactive fault management, improving power quality, network reliability and controlling technical losses. Other advantage of sensor-based technologies is the contribution to the reduction of greenhouse gas emissions, being able to maintain the health of LV networks in a sustainable and energy-efficient manner.

Sensor based applications being used in smart power grids and combined with demand side management contribute to efficient use of energy resources and optimised network operation, thus helping to reduce the carbon footprint.

Smart lighting to bring smart, bright future Considering the technology enhancement and increasing buying power of Indian consumers, smart lighting solutions will see robust growth

Smart lighting technology is all set to completely transform the lighting industry. The electrical industry is

Adopting to energy efficient LED solutions can reduce the consumption by 40-50 per cent.

Rajesh Naik, General Manager – Luminaires, Crompton Greaves Ltd.

mAy 2015

adopting smart lighting implies the obvious that how much a consumer is now aware and demands a better product. In addition, the government is adopting LEDs in public spaces. The interesting thing to look at is that while the transition from FTLs to CFLs took place over the last 20 years, the LEDs is going to take over the traditional lighting within the next 5 years.

Smart lighting and solving energy crisis Smart lighting plays a vital role in energy saving and natural scene creation even in closed doors. “We can save more than 50 per cent energy if we use LED lighting along with advanced control systems,” says Yoshiyuki Kato, Director Lighting, Anchor Electricals

Pvt. Ltd. “Smart lighting helps in creating an environment which will help in reducing the energy cost and improve the overall comfort through lighting effects. This also gives the opportunity of flexibility in the adoption of comfortable lighting solutions.”

About 20 per cent of lighting are consume in commercial premises and up to 30 per cent in residential applications.

According to Rajesh Naik, General Manager – Luminaires, Crompton Greaves Ltd., “Adopting to energy efficient LED solutions can reduce the consumption by 40-50 per cent.

If we adopt more smartness through dimming and sensing, we can increase the saving up to 60-65 per cent over Electrical & Power Review

existing products. This can ease the demand from existing installations in the tune of 10 per cent.”

Naveen Saxena, Country Head, Opple Lighting India, believes that LED technology brings benefits beyond energy savings.

He explains, “The specific advantages of LED over CFL include a longer life due to lesser heating during lifespan of 20,00050,000 hours of burning in comparison to CFLs that last 5,000 hours of burning on an average. While LEDs witness only a 20 per cent lumen depreciation at end of life, a CFLs undergoes a 50 per cent lumen depreciation.”

LEDs are tune-able and can be controlled digitally. Mr Saxena also believes that LEDs will be indispensable components of upcoming smart homes. Though LEDs cost higher than CFL, the cost of ownership is much lesser and they are healthier too as they do not contain any mercury.

Mr Saxena continues, “The Indian Government has also taken steps to reduce energy consumption at a mass scale and popularises LED amongst households. While the government has already announced LED streetlights in Delhi, Mumbai and other cities, it has subsidised LED bulbs for the household consumers and is targeting to install LED bulbs in 100 districts every year. The entire project of installing LED bulbs for domestic and street-lighting in 100 cities is targeted for completion by March 2016.”

LEDs can be easily the essential step towards energy conservation and sustainability. LEDs can help us save 55 million tonnes of carbon emissions per year by replacing 400 million bulbs with CFLs. Future of traditional lighting Although the time is running out, traditional lighting is still here to stay. Mr Kato explains, “Traditional lighting will sustain in the Indian market for a while, as the awareness and expensive price points of smart lighting exclude it from being favoured by the middle and lower socio-economic spectrums of the Indian society. However, the increasing awareness about the smart lighting and initiatives from the government and corporate will enable it to grow steadily and eventually replacing the traditional light sources.”

The main reason of unavailability of smart lighting to masses is lack of its access and affordability. “Awareness and government support in terms of regulations and tax support can drive adoption of smart lighting solutions at much faster pace,” says Mr Naik. “But with new consumers getting connected to electricity grid or through renewable energy, traditional lighting will continue to be around for next few years.”

However, Mr Saxena seems very optimistic about LEDs. He explains, “LEDs are poised to replace conventional

Industry Analysis lighting luminaries and highintensity discharge lamps in many key applications like street lighting, indoor and outdoor lighting apart from other niche industrial applications. Trends already substantiate this.”

About four out of 10 customers are buying LED lights, which are priced higher than CFLs. It is just a matter of time that the LEDs will take over the market. Manufacturers across India believe that LED lights will hold the CFLs in good stead and flood local markets in the next 4 years.

Contributing to growth The lighting manufacturers in India are queuing to join the bandwagon of LEDs. “We are focusing on offering a complete solution basket with LED lighting for residential and nonresidential segments,” explains Mr Kato.

“We have already introduced our LED products for residential, commercial, hospitality and retail segments.”

Anchor is also endeavouring towards providing LED lighting solutions for industrial and landscape lighting, in the near future. In the next 3 years, it aspires to be one of the top 3 LED lighting solution providers in India.

Then there is Crompton which has clear roadmap to get major share in LED market explosion. “We have complete range of LED products and solutions in each of the application categories,”

We can save more than 50 per cent energy if we use LED lighting along with advanced control systems.

says Mr Naik. “Continuous innovation on product, cost competitiveness and journey from product to solutions will be the key for success in this rapidly evolving market. With working partnerships and collaborations with leading LED eco-system partners, we are able to absorb and ready for future technologies. Reliability is given the highest attention in the product as customers are expecting 3- to 5-year warranties on the system. We have already initiated activities to be part of ‘Make In India’ through in-house production and backward integration.”

Future of smart lighting in India Considering the technology enhancement in India and increasing buying power of Indian consumers, smart lighting solutions segment will see robust growth, as more people are now choosing to adopt eco-friendly products and understanding their contribution towards environment and society.

According to Mr Naik, “Per capita income is increasing in India.

Awareness about green and energy efficiency is increasing. Convenience is driving buyer decisions. Make in India will boost industrial growth. All this will create positive impact on demand for smart lighting. With government drive on energy efficiency along with monitoring, there will big boost in smart lighting. Smart cities already planned will definitely have smart lighting, and the same will influence many more application segments to opt for smart lighting. With all positive impacts, smart lighting (i.e. efficient, convenient and communicable) has good opportunity in India.”

Even Mr Saxena thinks that the smart and efficient lighting is gaining tremendous foothold in India. He explains, “The key factors that are influencing this shift are evolution of the consumer mindset, rise in disposable household income and an increased tendency to spend. The Indian consumers have evolved over

the last few years to be not only more conscious of the environment, but also cognizant of the impact of good lighting and how it can create a great ambience. They are now open to adoption of new technology and making expensive purchases that are value for money, even over a period of time. This has led to a less than 50 per cent growth in LEDs vis-à-vis the less than 12 per cent growth in the lighting industry over the last couple of years.”

Nuclear power plant economies A detailed analysis on the factors affecting reduction and increase in prices There is no universal answer to the simple question: “What is the cost of a nuclear power plant (NPP) construction?” NPP market is not about consumer goods; it is exclusive and tailor made. Therefore, one should discuss the range of prices for nuclear reactors and the factors affecting reduction and increase in prices.

Today for energy consumers, it is very important to have the guaranteed price of kWh on the entire life cycle of NPP. The major question that is on the agenda is how the leading vendors will respond to this request?

Kirill Komarov, Deputy Director General, International Business and Development, Rosatom, says, “Any customer, regardless of the relations that it wishes to establish with us, i.e. hires us as the contractor or invites us as a partner, ultimately asks us the same question: what will be the price of 1 kWh of electric power generated by such plant? For such developing economies, it is essential to understand the pricing of electricity. And in this sense, it is where we and the customer have developed the logics of the cost of 1 kWh for the first time. In most cases our partners are not professional power engineers, nor nuclear power engineers, nor even energy companies. Sometimes those are industrial enterprises, municipalities and other energy

consumers who base their investment and development plans on how they can support such plans with energy supply at a stable predictable price.

“Therefore, today the market demands offers related to the cost price of 1 kWh of electric power, which is essential for the consumer. Actually, the consumer is not much interested in how electrical energy is produced; the most important thing is the price. We can guarantee a certain price for electrical energy generated by NPPs built by Rosatom, since we have constructed the entire process chain, from uranium production to construction of NPPs and sale of electrical energy.”

Mr Komarov also talks about the challenges faced the nuclear energy sector which is about ensuring competitive advantage in comparison with generation on the hydrocarbon raw materials. “Today they often say that nuclear energy is quite expensive, but this depends on calculations,” he explains. “It is true that NPPs are expensive to build, but the process of generation of electrical power is much cheaper in comparison with gas or coal generation. We have studied the volatility in raw materials markets in recent years, and the way the price for natural uranium and gas has been changing. The price range is quite broad in both cases. But the resulting ultimate cost of Electrical & Power Review

Feature electrical energy is different, since for an NPP the share of the fuel component is only 25-30 per cent of the operation cost, and for a gas or coal plant the share of the fuel component is 80-90 per cent.

“In this regard, the cost of production of kWh of electric energy on the nuclear power plant is subject in the smallest way to changes in the commodity market and most predictable for the investor and the end users.”

From the engineering point of view, leaving apart all business and political issues, it is crucial to speak about the overnight cost, i.e. the cost of an NPP as if it could be constructed overnight.

Overnight cost is affected by many factors, for instance, the reactor capacity. It is considered that the more powerful the reactor is, the cheaper each kilowatt of its capacity will be.

However, increased reactor capacity also has a “side effect” — the more powerful the reactor is, the more difficult it is to create a reliable, safe system for its operation and protection.

The French have already faced this. They offer EPR reactors which, at present, are the most powerful ones; however, no power units with such reactors have been constructed yet, and control systems are the problem.

Site conditions are another extremely important factor.

Countries and even separate regions differ in terms of climate, seismic data and other parameters. If the plant is constructed in the region where earthquakes are possible, more concrete and reinforcing bars will be needed to ensure its reliability, which means additional cost. Conditions on the site also affect such part of an NPP as cooling towers. These are huge concrete towers of 150 meters and higher. They are necessary in some cases, but sometimes it is possible to do without them.

The localisation is an important part of the NPP cost.

Involving local workforce and local enterprises usually enables construction cost reduction. This, of course, becomes possible when local businesses gain expertise in nuclear projects because safety is the most important thing for an NPP during the entire period of its operation (60 years and more). Cost is an important factor, but not the most important one. Indeed, who would like to live near an NPP constructed not by professionals but by a group of fishermen who charge half of the cost for their work?

Certain safety requirements for an NPP project also affect the cost. It varies depending on the country. For instance, most EU states do not consider new projects which do not include a core catcher (the U.S. propose such projects). In Russia, all new reactors have been constructed only with the core catcher for a long time, as we consider it extremely important for safety. With more safety requirements, the cost of NPP is to increase. Therefore, at the beginning of negotiations, the general contractor and the client always discuss which safety systems the proposed reactor is to include. Traditionally, the client makes the final decision.

Number of units (reactors) on the NPP site is another factor affecting the cost. There is a concept which we call learning curve. To put it simply, each next unit may cost less than the previous one due to the expertise gained during the construction and because subsequent units may use certain equipment jointly with already constructed ones. In many cases, building two reactors at once may cut the cost considerably, because the construction will use the same infrastructure.

To make a complete and comprehensible list all factors determining the NPP cost, one will have to prepare an engineering report with many pages. But one factor should be mentioned, this is the overall situation in the country’s nuclear industry. An NPP does not exist separately; the entire industry is always formed in relation to it: qualified nuclear power engineers, enterprises, employees of supervisory bodies, educational institutions and so forth. Of course, a country, which has no expertise, will have to spend more money to achieve the goals than the country which already operates many NPPs. But these are good investments, as they are made in the development of national technologies and economy, as well as good of the public in general.

So what is the cost of an NPP construction? The French will remain for a long time global leaders in terms of cost. Their reactors which they build in France and Finland will cost about €8.5 billion, which exceeds the cost of the Large Hadron Collider. Other nuclear technology suppliers still try to keep down the overnight cost ranging between $4-6 billion per reactor.

large size diesel engines ensures that the recirculated exhaust-gas is mixed at the lowest possible temperature with the air of combustion, resulting in effective reduction of nitrogen oxide emissions. This technology already now fulfils the future emission guidelines according to IMO (International Maritime Organisation), Tier (the US exhaust gas standard), EURO etc.

The emission tests were conducted at the

prominent Research Centre for Internal combustion engines and Thermodynamics at Rostock University in Germany.

In India, is there a level-playing field for overseas manufacturer like you?

To many people, heat exchangers’ is no rocket science and is just a fabrication. We do not believe in this and it is this attitude that has made GEA Heat Exchangers what it is today. GEA has many firsts to its credit including inventing the first elliptical finned tube technology, pioneering the compact technology etc. And, based on all our experiences and expertise’s we are providing optimised technology for the specific application and market segment.

These technological advances have tremendously helped us to retain a unique leadership position in the heat exchanger market worldwide. For the quality conscious niche segment, price never is the only criteria and it is the long years of trouble free performance our coolers give that matters. And, it is this market that we target.

For pumps and valves industry, the days of slumps are long gone

Pumps and valves industry pumping for growth In the power sector, pumps and valves industry is finding a new place to shine.

With new policies as well as “Make In India” initiative, the industry is moving towards the right direction. The days of slumps are long gone. The industry believes that the growth is just in the corner.

Potential in pumps and valves market Pumps and valves market has never been in a better position. Although, over the past 2 years, this industry has faced a little slump, the future has an immense potential.

“We can expect that this scenario will change soon,” says Milind B. Alwekar, Managing Director, Chemlin Pumps & Valves Pvt. Ltd. “All major pump manufacturers have either set up their manufacturing units in India or in the process of doing so, with the help of their local partners in business. We can foresee India to be developing as a manufacturing hub for the world market.”

Even Mahathi Parashuram, Head Marketing and Public Affairs, Grundfos India, thinks that there is always a huge potential for pumps in the country. He explains, “A recent study on Indian pumps industry published by TechSci Research says that the market for water pumps in

mAy 2015

India is expected to witness rapid growth at CAGR of around 12 per cent during 2015 to 2020. Agriculture and industrial sector are the major contributors to the growth of the pump industry in the country. Desalination plants are proving to be the next best water resource and with the number of such projects coming up in various locations in the country, demand for water pumps are going to be always on the increase.

“It is heartening to also see that the stakeholders both in the public and private sector are opting for energyefficient pumps which will provide them with quality service, energy conservation and ultimately saving on their operating costs.”

V. Krishnakumar, Vice President (Sales and Marketing), Aquasub Engineering also feels that the ‘Make in India’ initiative will give a boost to all domestic industries, including pump industry. He states, “Pump being an essential part in any process is an important product.

Whether it is used for clear water or dirty water or any other chemicals, you need to have the pump construction and the prime mover along with that.

When thrust is given to agriculture, the demand for agricultural pumps and

irrigation pumps will have huge demand.

Even for agriculture today electricity is one of the major bottlenecks in all states.

Just because electricity is not available, farming activities are not taking place.

Same is the case with the industry.”

Key technological trends Innovation is the key word in any industry, and pump industry isn’t any exception and experiencing a greater demand for intelligent pumping solutions. Mr Parashuram adds, “Some of the growing trends we can see in the pump industry are energy-efficient pumps to magnetic drive-based water pumps, EPC (Engineering, Procurement

Water treatment in industry and domestic purposes are going to be the key sectors which will drive the growth of the pump industry in the near future

Industry Analysis and Construction) based water pumps, pumps controlled through mobile phones, sharing of signals between two pumps and pumps communicating with monitoring systems.”

She adds, “Innovation is the heart of Grundfos. We have recently launched our TPE3 range of pumps which is one of the most intelligent ranges of pumping solutions available in the country. The specialty about this pump range is that it has the capacity to communicate between two pumps to maintain high level of operational efficiency with only minimal manual controlling required.”

In the past two years, the industry sees a major focus on energy-efficient operations. Mr Alwekar explains, “This is due to a better awareness amongst the user industry on saving power as well as striving for improving environmental balance. The pump industry is also gearing up to meet the requirements of the market, introducing new models with added features in more userfriendly, automated and safe operations.

The industry is seen more aggressively resorting to the use of modern design techniques, using flow simulation and structural simulation.”

Adding value to pumps and valves There are many subsectors that are adding value to the growth of pumps and valves market. According to Mr Alwekar, the three major sectors that would play an important role are oil, gas

and petrochemical; steel industry and power sector.

Other sectors too will show a moderate rise. “Water treatment in industry and domestic purposes are going to be the key sectors which will drive the growth of the pump industry in the near future,” says Mr Parashuram. “The low availability of water and the increasing demand for delivery and treatment of water will give a boost to the water-treatment industry and in turn the demand for pumps.

The rising consumption and decreasing supply of uncontaminated water is pushing up the market of desalination plants for treating seawater, in which pumps play a major role.”

He also talks about the energy efficiency and the growing demand of solar pumps.

“Given that the Indian Government is focusing on 100 smart cities, this will also result in the requirement for intelligent pumping solutions.”

Key challenges The pump market in India is mostly unorganised. Then there is the challenge of cheapest import. “Most of the time people only focus on the cost of the pump and not its quality and efficiency,” explains Mr Parashuram.

“This leads to a lot of energy being consumed, huge operating expenses and constant breakdowns. In most cases, environmental and other standards are also not being met or adhered to. It is imperative that industry as well as all consumers start looking at the life-cycle cost of a pump, its energy efficiency and carbon footprint in a serious manner.”

According to Mr Alwekar, “In India the pumps and valves manufacturers are mainly facing challenges from their low-cost local competitors in the mostly unorganised sector. This is leading to promotion of un-healthy business competition. The non-uniform tax structures, frequent changes in input costs, viz. power cost and labour cost, add into limitations on the Indian manufacturers for a long-term contract with their overseas partners on price

issues. Improvement in infrastructural facilities and better connectivity with Tier-II and smaller cities is required.”

The non-availability of raw material at international market price, power shortage, absence of skilled manpower and lack of support by various governments in creating demand are also other challenges.

Difference from imported products The Indian manufacturers are progressing quickly in the aspect of quality and price.

“In the pumps and valves sector, the difference in quality and appearance is slowly diminishing, and the Indian manufacturers are slowly coming up as world-class manufacturers,” says Mr Alwekar. “The continuous improvement in foundry technology has definitely helped in this development process. However, for some special applications in the nuclear power and oil sector, the foreign companies are still better in regard to technology and better metallurgy of the pump components.”

Mr Krishnakumar thinks that India is catching up with the world-class manufacturers. He adds, “When China supplies large volume of pumps to the global market, India’s share is negligible.

This is because we are not able to compete with China on price. But now China’s cost also is increasing, and India offers a better quality product than China. This will help us increase our share in global market.” mAy 2015

Concentrated solar power: heating up or fading up?

Starting with huge expectation, concentrated solar power (CSP)has faltered.

Can the government revive the exciting yet costly technology?

Under the Jawaharlal Nehru National Solar Mission (JNNSM), India aims to install 20,000 MW of solar power capacity by 2022, which includes both solar PV and CSP technologies. While solar PV has been the primary reason for installing over 1.7 GW of solar energy in the country, CSP has fell behind. In the first phase, 66 bids for an aggregate capacity of 2,911 MW were received against a requirement of 470 MW capacity, and only seven projects were awarded. However, about 320 MW of projects were delayed forcing the Ministry of New and Renewable Energy (MNRE) to extend the deadline.

The industry blamed low DNI as one of the reasons for unsuccessful projects, as projects were designed for low DNI levels

42

mAy 2015

(120 loops for 50 MW compared with 90 loops for 50 MW in Spain, without storage).

Solar developments CSP projects requires large capital investment and interest appears to be fading around the world. With price dropping for PV, ten developers constructing projects worth 315 MW have decided to change technologies.

Not only that, very few developers are showing any interest in CSP projects.

However, MNRE is very confident that CSP has a very good future in India. The ministry believes that one successful commissioning of a project will be enough to boost the confidence of investors.

Silver lining India is in definitely need for energy which has increased in the last few years. The coal supply chain is struggling to keep up with demand, and fossil fuel is expensive. It is doubtful that how long the government can subsidies on these.

Energy developers would face a lot of challenges to keep costs artificially low, as costs of imported coal are increasing.

“India has a manufacturing advantage, as it has experience in all the technologies and sub-component systems in CSP,” says Lavleen Singal, Founder, Acira Solar. “Just as China has emerged as the manufacturing base for PV, India could emerge as the production base for CSP technologies.”

Electrical & Power Review

Green Zone The brighter is the availability of DNI data which is improving day by day.

Weather stations by C-WET from the MNRE are shedding light over a previously obscure issue. This means that price and technology adjustments can be made by developers to adapt to the real DNI conditions and respond accordingly.

Several Indian manufacturers also attempt to develop a local supply chain for CSP. Now several companies are concentrating on CSP market, manufacturing tube receivers, frames, curved mirrors and other key components. Interestingly, many other industries use a variety of CSP components. For example, power block components and the manufacturing of steel, power components, control systems and civil construction are integral to the CSP industry. Then there are hydraulic drives, heat transfer fluids (HTF) and CSP adapted turbines.

Pulling investment Like the PV market, the CSP market in India depends on access to lowcost domestic financing to continue growing at a healthy rate. If reports to be believed that around ` 17,000 crore in debt financing is required to complete all the announced projects. Here come the challenges. Domestic financiers are reluctance to fund solar projects, projects employing CSP technology are considered even riskier. The ministry should encourage government-backed loan guarantees and work with the banks to share information on the developing CSP market track record.

The ministry should also facilitate collection of direct normal irradiance (DNI) data and build up confidence in the accuracy of DNI data. It doesn’t end here. The Indian government needs to analyse effective approaches to enforcement of renewable purchase obligations (RPOs) and development of a renewable energy certificates (RECs) market. In order to attract investment in solar projects and allow for a variety of technologies, a thriving REC market is must have.

Electrical & Power Review

Not only uplifting ‘Make in India’ programme or bringing thousands of job opportunity, domestic CSP industry has many valuable thing to add to the power sector. There are many other things that Indian government should concentrate on. The government should maintain a domestic content requirement or consider other support mechanisms. Then there should be R&D collaboration and innovation to encourage domestic production. Not to forget employing support measures as well as encouraging CSP manufacturers to establish facilities in India.

CSP costs have been reducing with increasing deployment, pretty much like PV. Deploying CSP projects (even 500 MW/year) would spur investments in domestic manufacturing leading to significant cost reduction. Domestic manufacturing would lead to R&D efforts with anticipated reduction in costs and improvements in performance.

CSP revival Solar biomass/fossil fuel hybrids, where solar can contribute up to 50 per cent of fuel saving, suddenly attracted a new wave of attention. A few months back, the Center for Study of Science, Technology and Policy (CSTEP) revealed that it would be build a 3 MW CSPbiomass power plant in Barun, Bihar.

Known as SCOPEBIG (Scalable CSP Optimised Power Plant Engineered with Biomass Integrated Gasification), the hybrid project is being set up under the EU-India cooperation on renewable energy. The project would cost about €8 million.

Biomass is abundant in India, especially in Bihar, and it is still untapped.

According to the MNRE estimation, India produces 500 million tonnes of biomass a year. Out of these, only 120150 million tonnes are not used.

The advantage of hybridising CSP with biomass is that such a plant can operate day or night — even in

prolonged periods of cloudiness. There are other advantages too. For example, it requires only small changes when optimising the design.

With the SCOPEBIG project, CSTEP is optimistic about the viability of CSPbiomass plants. At first, the centre would start with smaller scale for replication across India as well as study the social effect on rural areas.

The only concern is overcoming intermittency issues and meeting peak-load shortages. If hybridised CSP can overcome these, it could certainly help India become energy independent.

Future actions There are no CSP projects on the horizon. The question comes — what future lies for this industry? In order to make this industry happening, the government should a couple of key policy priorities to support the development of the CSP industry.

“CSP is a turbine based technology,” says Mr Singal.” What are the optimal capacities for turbine based technologies? About 250 MW? So why are CSP projects limited to 50 MW capacity? CSP projects should be more than 250 MW capacities.”

CSP, with thermal storage, provides firm power which no other renewable technology provides. Meeting peak power requirements and grid stability should be factored when comparing CSP costs with other renewables.

While awarding bidding, the ministry should be more stringent, as CSP is a complex technology. The JNNSM had over 60 bidders for 500 MW capacity projects, whereas Spain had more than 20 bidders for 2.5 GW capacity.

The government needs to work on policy to attract funds and develop confidence in the CSP market. It should also recognise, identify and promote the unique characteristics of the available technologies. mAy 2015

China plans to build solar power station in space by 2050 Since years scientists around the globe are trying to find out solutions for sustainable and environment friendly power generation. It seems that China has mastered the art by planning to construct the first solar power station in space China plans to construct a massive space solar power station 36,000 km above the ground in an attempt to cut down on greenhouse gases and solve energy crisis which the world faces currently.

According to Xinhua news agency, the solar space station is planned to be much bigger than the Apollo project and International Space Station in the space orbit, it will consist of large solar panels extending to 6 sq km which will enable the panels to capture maximum amount of solar energy. An experimental space solar power station is planned to be in place by 2030, while a commercially viable one to be ready by 2050.

The power station would be a super spacecraft on a geosynchronous orbit

equipped with huge solar panels. The electricity generated would be converted to microwaves or lasers and transmitted to a collector on Earth.

In 1941, U.S. science fiction writer Isaac Asimov had published the short story “Reason”, in which a space station transmits energy collected from the sun to various planets using microwave beams. A U.S. scientist Peter Glaser published an article in the journal Science in 1968, claiming a feasible design for the space solar power system.

Wang Xiji, 93, an academician of the Chinese Academy of Sciences (CAS) and a member of the International Academy of Astronautics, says Asimov’s fiction has a scientific basis. Wang is an advocate for the station. “An economically viable

space power station would be really huge, with the total area of the solar panels reaching 5 to 6 sq km,” he told Xinhua. The space solar station will be equivalent to 12 of Beijing’s Tian’anmen Square, the largest public square in the world, or nearly two New York Central Parks. “May be people on Earth could see it in the sky at night, like a star,” says Wang.

Wang said the electricity generated from the ground-based solar plants fluctuates with night, day and weather, while a space-based generator can collect energy 99 per cent of the time.

Space-based solar panels can generate about ten times as much electricity as ground-based panels per unit area, says Duan Baoyan, a member of the Chinese Electrical & Power Review

Green Zone Academy of Engineering (CAE). “If we have space solar power technology, hopefully we could solve the energy crisis on Earth,” he says.

There is a need to replace the traditional fossil fuels with clean and environment friendly sources of energy. However, ground based resources like sun, wind, water and other natural resources are very limited and are not constant in terms of reliability. “The world will panic when the fossil fuels can no longer sustain human development. We must acquire space solar power technology before then,” says Wang.

“Whoever obtains the technology first could occupy the future energy market.

So it’s of great strategic significance,” Wang says. Construction of a space solar power station will be a milestone for human utilisation of space resources. And it will promote technological progress in the fields of energy, electricity, materials

and aerospace. Countries such as the United States and Japan have studied a space solar power station. Currently, Japan is leading in the development of wireless power transmission technology.

Some Chinese research institutes and universities have also conducted studies related to space solar power technology in recent years.

For instance, a commercially viable space power station would weigh more than 10,000 tons. But few rockets can carry a payload of more than 100 tons to low Earth orbit. “We need a cheap heavylift launch vehicle,” says Wang, who has designed China’s first carrier rocket more than 40 years ago. “We also need to make very thin and light solar panels. The weight of the panel must be less than 200 grams per square meter.” He also points out that the space solar power station could become economically viable only when the efficiency of wireless power transmission, using either micro wave

or laser radiation, reaches around 50 per cent. However, he is confident that China can build a space solar power station.

“When space solar energy becomes our main energy, people will no longer worry about smog or the greenhouse effect,” says Wang. He adds, “The development of wireless power transmission technology will be a great advance. After the technology is applied, power cables will not be needed anywhere in the world.

Just imagine what a world it will be.”

Li Ming, vice president of the China Academy of Space Technology said, “China will build a space station in around 2020, which will open an opportunity to develop space solar power technology.”

Apart from avoiding smog and pollution generated from fossil fuels, the space station will help in bridging the gap for energy. Currently, China is the world’s largest energy consumer and also the world’s top carbon emitter.

MNRE and TERI talk about grid-connected rooftop solar power in India TERI and MNRE held a day-long conference at the India Habitat Centre to deliberate upon the challenges and strategies for the successful implementation of the MNRE scheme for grid-connected rooftop solar power in India.

In the keynote address, Tarun Kapoor, Joint Secretary, MNRE, said, “Gridconnected rooftop solar power is the most important single sector as far as renewables are concerned. This 40,000 MW project requires an investment of up to Rs 4 lakh crore. This is a big opportunity for all business.” He also encouraged start-up businesses to come forward and invest as “to create and sustain such a big market where everyone has to put in the effort required”. So far 20 state regulators have issued connections, and 17 states have issues policies in this regard, the joint secretary mentioned.

Electrical & Power Review

Talking about MNRE withdrawing subsidy, he said the ministry will “continue to work on options that get the consumers cheap loans”, while looking at “multilateral and bilateral funding” that attracts money in the country at a cheap rate”.

Dr Leena Srivastava, Acting Director General, TERI, said in her welcome address, “It will be interesting to see how we can make India a global leader in this sector, without impacting climate change. Taking a systemic approach towards implementing this large and ambitious programme, ensuring it is a win-win for all stakeholders, is critically important and underlies every action we do.” Focusing on the fact that ‘sharing the pie’ is crucial, she said that private sector is only going to engage in this initiative if they see “adequate” returns in this”.

Talking about the World Bank’s partnership with MNRE, Mohua

Mukherjee, Senior Energy Specialist, World Bank, said that “it is interested in developing various business models in India.” “The World Bank wants to catalyse private funding through partnership with commercial banks”. The goal, she said, is to make this form of energy source “a consumer commodity that nobody wants to be without.”

The conference was organised by MNRE and TERI with a special focus on gridconnected rooftop solar power, which is a flagship initiative of the government to push this sector. It forms a huge 40 GW component of the rooftop solar power out of India’s ambitious 100 GW solar power target by 2022. In this context, this conference is designed to serve as a platform for deliberation on the challenges to the implementation of grid-connected solar power as well as possible interventions and formulation of success strategies. mAy 2015

Schneider’s new PM8000 meters to simplify power quality Buildings and industrial energy users now have a reason to cheer, as Schneider Electric launches the PowerLogic PM8000 series power meter that gives power quality compliance information and analyses capabilities that were once reserved for more advanced meters. Being aware of the power quality related penalties that Indian industry and building consumers face and knowing the importance of capturing such information for the consumer, Schneider Electric has designed PM8000 range in accordance with power quality standards IEC 61000-4-30 Class S and IEC 62586 – latest update by IEC on PQ standards, to ensure that consumer can meet the contractual obligations for the quality of electrical supply. PM8000 offers power quality analysis capabilities, such as EN 50160 compliance, sag/swell detection, waveform capture, disturbance direction detection and trending and forecasting to

help facility managers detect, mitigate and correct adverse conditions.

“Power quality monitoring is crucial for power-critical facilities like hospitals, data centres, and large manufacturers,” noted Gaurang Desai, Marketing Manager, Schneider Electric. “We designed the PM8000 series to aid with both PQ compliance monitoring and analysis. If a PQ event does occur, the patented disturbance direction detection feature helps identify the location by determining if it occurred upstream or downstream of the meter, so correcting the problem is much faster.”

The highly accurate, reliable meters are compliant with ANSI C12.20 Class 0.2, IEC 62053-22 Class 0.2S (real energy) and IEC 61557-12. This accuracy combined with the meter’s extensive I/O options makes the PM8000 series meters ideal for the

unified metering of all WAGES (water, air, gas, electricity and steam) utilities. Meters are available in both panel-mount and DIN rail-mount form factors and boast highvisibility colour displays.

Engineered on a compact, modular and flexible platform, the PowerLogic PM8000 series meters are first in 96-mm size to have the versatility to perform nearly any metering job, including acting as a Ethernet gateway for downstream Modbus slaves at key points throughout a facility.

Megger unveils new cable test and diagnosis system used for DC tests and sheath tests to the IEC 60229 standard. When paired with a step voltage sensor, it can even be used for precise pinpointing of sheath faults.

Megger launches TDS NT – a unique, all-inone cable testing and diagnosis system. It offers two well-proven wave forms – Very Low Frequency Cosine Rectangular (VLF CR) for withstand testing and Damped AC (DAC) voltage for non-destructive partial discharge diagnosis. These can be used to test cables to international standards such as the IEEE 400.3 and IEC 60502-2. The TDS can also be

mAy 2015

Network operators can now get faster and significantly more reliable information about the quality and the condition of their cables.

This is made possible thanks to the brandnew 50 Hz slope technology. For the first time, it has become possible to immediately locate faults in underground cables during the actual PD measurement.

With the 50 Hz slope technology for the first time worldwide a withstand test with VLF CR and PD diagnosis with DAC is combined in one unit, Megger claims.

The innovation allows an efficient and integrated solution for precise inventory of

the network infrastructure. Most importantly, the PD measurement data, gained with the VLF CR or with the DAC test voltage, can be compared directly with the 50 / 60 Hz network voltage.

TDS NT consists of a multifunctional, compact voltage source and a PD detector. It can be used to test cables according to the international standards (e.g. IEC 60502-2 and IEEE 400.2) with VLF-CR. In addition, a PD diagnosis using the new 50 Hz slope technology can be performed simultaneously with the help of the PD detector. Alternatively, the TDS NT can also be used for PD diagnosis with the proven DAC voltage. In practice, the PD diagnosis has been established as an effective method of measurement. It is especially useful for commissioning testing, as it is the only way to check to reliably check the quality of workmanship of the accessories.

Electrotherm Solar Power House Solar Power House (SPH) is a consolidated smart solution of DC inverter circuit and AC power circuit placed together under the same roof confined in a thermally insulated outdoor container.

The combined solution can easily be transported to a solar park and generate MW capacity of power in no time. Due to the extremely poor availability of resources at the remote villages where the solar park is usually located, the supply of sensitive instruments like power inverter and associated power products and control instruments and their respective power and control cable connections are not only a challenge in today’s world but needs skilled labor and substantial integration time. Due to this, site integration of control and instruments becomes a daunting task in solar field. Moreover, on completion of terminal connections of various instruments, each of them needs to be tested to ensure overall equipment performance. Thus it is highly difficult to get required amount of output at site within an extremely tight project completion schedule.

Electrotherm having its strong R&D background in solar inverter transformer and solar EPC solutions with its state-ofthe-art manufacturing facility in Gujarat for power and various other transformers has taken the initiative to introduce its most reliable and smart substation solution to cater to solar power generation industries which help solar industries to build power stations in record time. The solution is just a plug and play device. These robust and high-tech container solutions are easy to ship and commission at remote site without any dependence on skilled

50

mAy 2015

manpower or equipment suppliers. Each AC and DC container together with associated auxiliary equipment can handle power up to 2.5 MW within a smart dimension of L (11,000 mm) X B (2,800 mm) X H (3,200 mm). The DC container accommodates solar inverters of reputed make along with separate standalone SCADA solution.

The factory-built product is completely integrated and tested in combination with DC circuit and the AC circuit before shipment which is the biggest challenge in any solar project. It also helps reducing the integration cost at site and dependency on so many agencies. There is an add-on advantage attached to it, all the critical components are pre mapped in the container solution to make it fail safe and accordingly Alarm and Trip circuits are designed and signals are wired up to the SCADA panels which then send the hierarchy signal to central SCADA server for preliminary data management and necessary proactive actions. With intelligent door devices and smart communication facility, the SPH helps customer to know about each container power output with a time axis while sitting at a remote distance.

With the age old experience in reliable transformer design and manufacturing, ET selects the right design of low-loss solar inverter transformers integrated with high-class HT switch gear to provide a very efficient and reliable AC circuit to handle the MW power flow up to the grid in a compact and reliable manner while controlling and monitoring the DC connection continuously to record the Inverter DC power flow in to the

cubicle. The supporting circuits for reliable operation of inverters backed up with battery and UPS make the customer free from arranging resources to complete the integration. Therefore, SPH is an independent and preferred solution which helps customer to build and operate several MW capacity solar park within a shorter time frame. The biggest advantage is that all under one roof and no connection to be done at site. According to Electrotherm (India), this is a compact solution as against conventional substation which involves huge cabling work at site and dependence on many agencies. It not only helps the customer to avoid civil work at site but also helps to avoid HT cable laying and termination work, LT cable laying and termination work, DC cable laying and termination work, inverter DC and AC cable connection, transformer installation and cable termination, installation and connection of HT panels etc. etc. For a typical 50 MW power plant, client needs to just order out 20 such containers to ship at site which can then be integrated with PV modules already installed and connected at site to their respective combiner boxes, Electrotherm (India) informs. The singlewindow solution also extends up to site commissioning assistance to help customer commission the power plant without any hurdle. ET solar team also offers complete turnkey solution up to 300 MW single solar park.

Sharplex auto backwash filter When the differential pressure reaches its pre-set values, the back-flushing process starts automatically. During back-flushing a geared motor rotates the flushing arm under each filter element in succession and the backflushing valve opens briefly. Due to a pressure differential between the filtrate side (clean water) and to open back-flushing line, a small volume of the filtrate is flushed back through the filter elements. The impurities or sediments which may collected on side of the filter elements is loosened and flushed out of the filter via the flushing arm. When all elements in the filter have been cleaned, the backflushing cycle is complete. When one filter element is under back-flushing other elements continue the filtration and therefore filtration process do not stop and it is continuous.

Major features

Operation The water to be filtered enters into the filter and flows through the slotted tube elements from inside to outside. Impurities or sediments particles are retained on the smooth inner side of the filter elements. The particular design and shape of filter element guarantee an even flow resulting in a low pressure drop and equal loading of the filter area. As the loading of the filter area increases steadily during the filtration process, the differential pressure between the contaminated and the clean sides of the filter element also increases.

Electrical & Power Review

• Reduce operating and maintenance cost • The slotted tube filter element with filtration rates of 50 to 3,000 um • The filtration flow is not interrupted during the back flushing procedure • Flow rates of up to 10,000 M3/Hr. • Numerous combination of materials and equipment as well as individually adjustable control parameters.

• Reduce costs due to space saving • Ready to operate the unit with simple installation and commissioning • Fully automatic operation. No intervention by staff required. Low operating cost.

Applications • Power station: Treatment of industrial water for cooling generators and filtration of cooling water, as side stream filter • Process industry: By filtration of cooling water, protect the surface of heat exchangers and other

DEIF’s solar solutions: a boon to power sector DEIF Automatic Solar Controller (ASC) enables to share the load between solar PV cell and diesel/gas genset with maximum solar penetration, thus results in maximised savings even during utility failure DEIF ASC

Solar Power – The need of the hour Across the world, the need to make the energy portfolio environment friendly is a pressing need. Among the renewable sources, solar power is gaining momentum in India with the push given by government and the abundant solar potential in India. The increasing demand is driving down the cost of solar energy which is attracting more and more investment in this sector.

to have efficient controls that will enable solar penetration to maximum possible extent including the possibility of exporting the excess power back to the grid.

Challenge with solar In a contemporary system, solar power can only be utilised as long as the utility supply is available. In the absence of utility, solar power can no longer deliver the power and the diesel generators come in to deliver the backup power.

The Solar systems are not geared up to supply power along with the diesel or

While the investment and increasing of solar share in the energy sources is fully justified, it is also equally important

gas genset as the load sharing between the two groups is a challenge. This leads to burning the fuel (diesel/gas) for the genset to take the entire load for the duration for which the utility is absent, in spite of solar power source being available.

DEIF’s answer to the challenge DEIF has come up with an innovative solution to this challenge. DEIF introduces the Automatic Solar Controller (ASC), a solution that provides integrated solution for systems with utility, diesel and solar power source.

Electrical & Power Review

POWER BRAND The system provides an interface between the diesel/gas genset and solar, with or without presence of utility power - a solution that enables you to share the load between solar PV cell and diesel/gas genset with maximum solar penetration, thus resulting in maximised savings even during utility failure.

DEIF solutions being cost-effective balance your economy and conserve the environment as they are highly efficient.

A solar system consists of series of PV cells connected to their respective inverters.

DEIF’s solar controller is connected to the master inverter of the group of inverters and interconnected among utility and genset controllers through CAN bus communication. DEIF’s solar controller serves as an interface between solar source and the diesel genset controllers/ utility power, namely Advanced Genset Controllers (AGC), over the CAN bus to adjust power output to meet the load requirement with solar system taking

the maximum load share. When the utility fails, genset start up to provide the reference and provide minimum load that will let it run efficiently and let the solar meet the rest of the demand.

If the solar power output decreases due to bad sunlight, the deficit will be met by diesel/gas genset through the intelligent interface, thus ensuring reliable supply of power in all conditions.

If the export of power from Solar is not demanded then the Advanced Solar Controller will restrict the solar generation to the desired limit.

How much can you save?

On an average, considering power loss of up to 20 hours per week implies that in a year you can have almost 1,000 hours of lack of utility power. Considering that the diesel consumption normally is of 125 litres per hour and assuming 1.5 $/ litre as cost of diesel, for 1,000 hours of no utility power, $ 187.5 per hour is the cost for running a diesel genset for one

hour. For 1,000 hours you would spend $ 1,87,500 and for running two gensets, the total spending will be $ 3,75,000 on fuel cost alone. In addition, the cost for handling the fuel, managing resources, maintenance of genset, gas emissions, and environmental setbacks add to the overheads.

DEIF’s solar solution enables to use solar power even in the absence of utility with high solar penetration. For example, with a 60 per cent solar penetration one can run just one genset and save on fuel cost of the other in the period of utility failure which implies a saving of $ 1,87,500. Using solar for the additional period of the year can make that period also further green and help maximise the project’s overall return on investment.

DEIF’s solar solution can be a boon to India’s evolving solar sector.

With the new technologies, we are bringing in. We will now create an ambitious grid programme that will meet the country’s demand.”

Devendra Chaudhury, Special Secretary, the Ministry of Power, said, “The entire power sector is gearing up to meet the government’s vision of power for all. We need to create an access platform which will help us provide electricity to the entire population.”

Speaking on this grand occasion, RN Nayak, Chairman and Managing Director, Power Grid Corporation, said, “The government’s

ambitious plan to provide 24/7 power to all in the country by 2019 will require the deployment of latest technologies in the field of transmission, distribution, intelligent devices, information and communication technology. Against this background, GRIDTECH 2015 is the foremost platform where all leading stakeholders reiterate their commitment to bring about a transformative change in the sector thereby ensuring quality as well as affordability of power for all citizens.”

India’s transmission and distribution network is one of the largest and complicated in the world. GRIDTECH 2015, in turn, has become the stage which saw, like always, leading minds and enterprises coming together in their endeavour to make India’s network system the most efficient one which will help shape the government’s dream of power to all. mAy 2015
