4 Electrical Monitor November 2014
Waking up to the potential he way the Indian solar power industry has been shaping up over the past few years is inspiring. It appears, rather strongly, that solar energy would be a big propeller of India’s renewable energy ambitions. The Jawaharlal Nehru National Solar Mission (JNNSM), announced in 2010 by the then UPA government, is being actively taken forward in the newly-elected NDA regime.
T
For the third year in a row, grid-connected solar installations are set to be around the 1-GW mark. Solar installations are being driven not only by the JNNSM but also by state government incentives. In fact, states are poised to play a much more prominent role in India’s solar story. The proposal of levying anti-dumping duties on cells and modules imported from US, China, Taiwan and Malaysia was a contentious issue this year, which to a significant extent, dampened the pace of solar additions. The government finally allowed the August 22, 2014 deadline for this proposal to lapse, thereby permitting such imports. Projects, which were stalled for want of clarity on the anti-dumping duty case, have now thankfully revived. JNNSM also stipulated that solar capacity worth 375 mw, out of the total 750 mw under Phase-2, Batch-1, had to come up with domestic equipment. Though some solar developers were circumspect of Indian suppliers being able to deliver equipment, the issue appears to have resolved with the capacity being successfully allotted to developers. While the JNNSM is chugging along and the overall target of 20 GW of gridconnected solar capacity by 2022 appears tenable, there are some issues that need resolution, if solar energy has to become a sustainable activity. Firstly, the attitude of state government utilities towards renewable purchase obligations (RPO) is found to be callous. With RPOs being bifurcated into solar and non-solar, state utilities need to be increasingly conscious of solar power in their energy mix. Secondly, the Indian solar equipment industry needs not just to build capacity but also ensure that it is technically sound and cost effective. Indian equipment so far has had only a trifling role in the total installed capacity today. Indian manufacturers of solar equipment should aim at deriving business on their own competence, without relying on government policies like the domestic content requirement (DCR) norms seen in the recent rounds of JNNSM. Besides, India does have strong export potential. Incidentally, exports of Indian solar equipment have, according to reliable estimates, doubled in FY14. India has definitely woken up to its immense solar potential. The time is now to get up and act in earnest.

CRA has observed improvement in distribution loss levels for discoms in 12 states in the period FY07 to FY13 while a deterioration or limited progress in reducing loss levels has been seen in five states. In the remaining two states, loss levels have remained almost unchanged. Despite this improvement, the distribution losses remain relatively high in a majority of the states— with discoms in 10 states showing losses higher than 20 per cent loss in FY13. Discoms which have seen a deterioration or limited progress in reducing loss levels are in the states of Uttar Pradesh, Jammu & Kashmir, Bihar, Chhattisgarh and Odisha where the loss levels in FY 2013 remained significantly higher as compared with the national average.
I
ICRA estimates average all India AT&C loss levels in the range of 27 per cent for FY13. This is significantly higher than what is targeted and points to a considerable scope for reduction in loss levels. SERCs in 11 of the 19 states under study have approved distribution loss trajectory till FY16. SERCs while approving tariff determination have stuck to pre-approved loss trajectory even though actual loss levels remained much higher and this in turn has led to disapproval of a significant revenue gaps as projected by utilities in tariff petition filings in many states. Even for discoms where such deviation is low, under-recovery in power purchase costs arise because of AT&C loss levels being higher (310 per cent) than the approved loss levels. With respect to capital expenditure approved by SERCs for strengthening of the distribution infrastructure, aggregate capital expenditure is estimated at about Rs.440 billion in FY15 which represents an increase of 8 per cent over the previous year. Besides the distribution strengthening schemes, utilities in eight states have already implemented feeder separation schemes, the ICRA release said.

Rittal India to roll out SS enclosures
Jacob Chandy, Vice President—Sales & Marketing, Rittal India Pvt Ltd ittal India is planning to soon launch stainless steel enclosures. Speaking to Electrical Monitor at the recently-held Automation 2014 in Mumbai, Jacob Chandy, Vice President—Sales & Marketing, Rittal India Pvt Ltd, said that the company would soon be installing new machines to roll out small stainless steel wallmounted enclosures. This apart, a
R
complete plug-and-play enclosure is also on the anvil, especially for data centre applications, Chandy said. Discussing the current market scenario, Jacob Chandy observed that even while there is much optimism regarding revival of investments, no projects have formally taken off as such. Even if projects do get into implementation, it would benefit Rittal India only after a time lag of a year, as an enclosure is usually required during the last leg of project commissioning. “We could probably benefit from revival in projects in around 2016,” the Rittal India official explained. During 2014, Rittal India saw its business riding on the telecom wave. The 4G rollout, by large players like Reliance and Airtel, had a positive bearing on the company’s performance. Dwelling on the market for enclosures, Chandy noted that these products are not bought directly by the end users. Rittal India deals mainly with system integrators, electrical contractors or process automation contractors. However, Rittal India is also witnessing at B2C dimension to its business where products like server
Indigenous technology for Zi-Al conductors agpur-based Jawaharlal Nehru Aluminium Research Development & Design Centre (JNARDDC) is working on a new technology to make power conductors out of aluminium and zircon alloy. The new-generation conductors, which will replace conventional All Aluminium Alloy Conductor (AAAC) or the Aluminium Conductor Steel Reinforced (ACSR), will be able to carry double the current at extremely high temperatures (about 210 degrees). The project is being conducted jointly by JNARDDC and the Hyderabad based Non-Ferrous Materials Technology Development Centre (NFMTDC), which will test the properties of the material by making wires from it in a pilot scale plant before the technology is transferred to commercial cable manufacturers. In fact, the wires made from this alloy could in emergency or peak periods also carry current efficiently at 260-270 degrees. Hence this new material is called Super Thermal Aluminium (STAL) conductors. Though STAL technology is already being used in the western world, it is economically nonfeasible for import, it is report. The JNARDDC research will reduce the cable cost to one tenth of the present cost.

racks, or enclosures for cooling or security monitoring are sold directly to the end user, which are companies mainly in the IT, banking and the financial sectors. Regarding the market microstructure, Chandy made some pertinent observations. He explained that the market for electrical enclosures was dominated, to a great extent of 80 per cent, by players in the unorganized sector. In the formal segment, there are 8-10 large players that include domestic companies that have grown in size over the years, and multinationals like Rittal. He also observed that the Indian customer is getting quality conscious and this bodes well for Rittal. Players in the unorganized segment are bogged down by inefficient economies of scale and rising labour costs. “Even a skilled welder is rare to come by,” he remarked. Marginal companies in the unorganized sector will ultimately be weeded out, the Rittal India official felt. However, when it comes to a company like Rittal, with a production level of 850 panels per day, there is significant economy of scale that favourably translates into lower costs for the consumer. “Besides, Rittal is globally known for its high quality standards,” he asserted. This made a win-win situation for the quality conscious customer and for Rittal, summarized Jacob Chandy.

Werner expects rapid growth in India over 3-4 years erman electrical component manufacturer Werner Electric expects to see rapid growth in its Indian operations over the next 3-4 years, according to Gary Weston, Marketing Director. Weston interacted with Electrical Monitor during the recently-held Automation 2014 event in Mumbai. Werner was established in 1948 in Germany and today operates globally with a particularly strong presence in USA and Europe. It set up its Indian subsidiary in 2011. “It was very slow for the first two years but now we have got very busy,” observed Weston. Discussing its operations in India, the Werner official explained that though Werner is a big name in the electrical component industry, the cost of importing equipment proved expensive for the Indian consumer. “Now, the local customer can get German quality at Indian prices,” said Weston. Explaining the current modus operandi, Weston noted that components are imported from Germany and assembled at its Indian plants located in Maharashtra and Karnataka. This gives relief in import duty that makes products more affordable for the Indian consumer, the official explained, stressing that the entire range of over 40,000 products was now available in India. Explaining the psyche of the Indian consumer, Weston said that earlier Indian customers were price-conscious leading to widespread import of equipment from China. However,
G
cheaper Chinese equipment failed to handle tough Indian conditions, resulting in Indians preferring better quality products. Though German products were much superior and reliable “their prices were difficult to budget,” observed Weston. Now, with Werner beginning assembly of its products in India, the Indian consumer has a highly cost-effective option on hand. Werner caters to a wide range of industries like process automation, oil & gas, mining, pharmaceuticals, automobiles, etc. Summarizing Werner ’s current activities, Weston explained that the company was building brand credibility in India and educating engineers about the company’s wide range of products. Typical decision makers and influencers include consultants, purchase departments of companies, technical consultants, etc. “We are going through the rigorous process of proving our products to decision-makers and stressing on our cost-effectiveness.” The coming years look very exciting, said Weston, “We are opening new offices and inducting new sales and technical staff. In the long run, we have plans to make India the hub for catering to the south-east Asian markets.”

SCFCL technology can help Indian utilities to boost efficiency — Omkaram Nalamasu (Ph.D) Senior Vice President & Chief Technology Officer, Applied Materials, Inc.
Tell us in some detail about the superconducting fault current limiter (SCFCL) developed by Applied Materials and the types of faults that it could protect an electric grid from. Applied Materials used its expertise in high-voltage engineering design, power systems integration and systems engineering to develop its superconducting fault current limiter. Our SCFCL is designed to provide critical 'Impedance on Demand' capability only when the system needs it to reduce the fault levels. When a fault occurs, the superconducting material experiences a phase change caused by the in-rush of large current and becomes resistive, prompting the current to
transition to a properly sized shunt reactor that limits the current to an acceptable value. When the system is running under nominal conditions, the load current flows through the superconducting portion of the device where it has virtually zero impedance. Therefore, under nominal conditions there is little or no voltage drop and no active or reactive power loss associated with the SCFCL. SCFCLs have numerous applications throughout the grid. Applied's SCFCL can be scaled to meet varying needs in generation, transmission and distribution up to 400kV and fault currents greater than 100kA. They can be installed in any location or interconnection point where the mitigation of current benefits the overall performance of the electric system. What could be typical causes of a sudden power surge and what detrimental impact could it have on a power grid? Power surges are caused by a variety of factors including lightning strikes, insulator flashover, de-capping of insulators, conductors snapping, broken earth wires, downed trees or crossed power lines. During a surge, the excessive fault current that flows through the electrical system can result in failure of one section of the system or damage expensive grid equipment by causing a circuit breaker to trip or a blown fuse. Utilities can use SCFCLs to protect their grid by limiting the amount of current flowing through the system, allowing for continual uninterrupted operation.

Technology: SCFCL by Applied Materials, Inc. impedance during normal operation, which allows for a more stable system. What is the comparison in terms of capital costs? Overall, in terms of capital costs, Applied's SCFCL is a costeffective solution that is highly customizable to accommodate different budgets. Please discuss Applied's plans of launching its SCFCLs in India. Specifically, by when can we expect the country's first installation? We are currently in advanced technical discussions with several leading transmission utility companies in India. If everything goes according to schedule, we could see the first SCFCL installation in 1 -2 years. Promotion of new technology in the traditionally conservative power utilities sector can be a difficult proposition. What is your view? Given the responsibility of the utilities to provide reliable energy to a growing populous, it's understandable that any new technology must be carefully assessed. However, we've found as fault current levels increase and become a larger problem for utilities, they are open to considering advanced solutions like our SCFCL. Also appealing is the fact that a recognized technology leader like Applied Materials is the company offering SCFCL technology. Our proven track record in developing and supporting technologies that have enabled the successful growth of several industries helps to relieve concerns over adopting this new solution.
Where have SCFCLs by Applied been installed so far? How has the overall performance been? Applied's SCFCLs are currently installed in two locations in the US. One of the sites is in California, and the other, more recent placement, is at a major utility in New York State. The different climates of these locations have given us the opportunity to show how our solution performs in diverse weather conditions. With regard to how our SCFCLs are working, the unit at the New York installation is performing as intended and has protected the electrical system from six faults so far. Please explain how SCFCLs of Applied are superior to conventional current limiting reactors. Compared to conventional methods, SCFCLs offer a technically advanced, cost-effective solution to managing fault currents. For example, traditional methods often employ explosive fault-limiting fuses to limit fault current, but they require replacing the fuse after it blows, which is expensive. They are also only available for voltages below 35kV. Series reactors are also used but they have constant high reactive losses, are bulky, and contribute to grid voltage drops. SCFCLs overcome these limitations. In addition, rising fault current levels increase the need for larger and more costly high impedance transformers. In contrast to these transformers, SCFCLs operate with little to no
24 Electrical Monitor November 2014
Do you feel that private utilities could be a good starting point for introducing SCFCL's to India? Compared to government-owned utilities, private utility participation in the transmission sector is limited. Therefore, we work with all utility companies that are seeking to solve their high fault current problem. Does Applied's SCFCL technology meet the needs of an entire electricity distribution system including India's planned UHVAC (1,200kV) initiatives? Applied's SCFCL is usable in both distribution and transmission levels—at voltage ranges between 6.6kV and 400kV. We plan on scaling the technology to the UHVAC range as the need arises and the technology matures. Please discuss how you would like to see the Indian power grid adopting SCFCL technology over the next 3-4 years. India has significantly improved its power generation capacity over the past decade to fulfil its goal of providing stable and reliable electricity to the entire country. As part of this objective, the utilities have also focused on upgrading the transmission network. By effectively protecting the system against faults, SCFCL technology may be able to help Indian utilities boost the efficiency and reliability of the country's electric transmission and distribution. We look forward to working closely with the utilities in India to install and operate our SCFCLs to support continued energy expansion and the improved performance of the Indian power ecosystem.

Enhancement of motor rating S. P. KHADE Director (Technical), Mumbai Metropolitan Region Development Authority INTRODUCTION he induction motors available in the market have their ratings indicated on the name plates. This rating is decided arbitrarily and is not the maximum output of an induction motor. This arbitrary rating results in under utilisation of the motor. The NEMA and IEC standard are not helpful for the manufacturer to make use of full potential. This article will help the motor manufactures to enhance their motor rating with NO additional expenditure. It gives the full potential available in any motor. It will lead to increase in profitability and will also optimise the use of precious material like copper.
T
work out a slip corresponding to the maximum output. The ratings of motor now decided arbitrarily can be decided mathematically thereafter.
TORQUE EQUATION The torque equation is Where, T is the torque, S is the slip, Ns is the synchronous speed, E1 is voltage
developed in stator, r2 and x2 are the resistance and reactance of the rotor. The slip at which the maximum torque occurs, is governed by an equation, Where Sm is the slip at which Tm, the maximum torque occurs.
Power,

, , a constant.
To get maximum P, differentiate w.r.t. s and equate to 0.
This will give,
This is the quadratic equation and the roots are,
RATING OF MOTOR The different torques associated with the induction motor are indicated in Fig.1. The load torque must always be less than locked rotor torque and the pull up torque. Breakdown torque is the maximum torque which a machine can develop. Full load torque is now normally assumed around half of the maximum torque. The rating of the motor is decided by this assumed value, which needs a rethinking. P is the point on the curve which corresponds to slips in equation (1). With the full load torque of 50% of the break down torque, the ratio of full load torque to the maximum torque is 2. Table 3.9 in book [1] gives the values of this ratio adopted by both IEC and NEMA. The table indicates that these values are decided arbitrarily. The values change with ratings and number of poles. The same ratios are not adopted by these two standards. The slip corresponding to this arbitrary ratio does not give a value of slip by use of which the motor can give maximum output. It is possible to
26 Electrical Monitor November 2014
MAXIMUM POWER DELIVERED BY MOTOR The ratio of 2 or around 2 of Tm to Tfull might have been decided by considering the torque slip curve as a straight line in stable region. But it should be remembered that this is not a straight line.
Since
To keep the value of slip as positive, consider the positive sign of the second term. s for maximum power is, ………….(1)
Let’s work out the maximum power from the original equation.
Speed at any instant is (1 - s) Ns. Power is a function of the torque and speed
The rating of the motor therefore should be decided by the slip for which the motor will give maximum output as given in the equation (1) above. The experimental results by use of slip derived in equation(1) above confirm that the motor does give the maximum output at this slip. The mechanical output of a motor is proportional for copper loss. It is therefore natural that, for more mechanical output, the copper loss will be more. In an attempt to keep copper loss at low value, we underutilise a motor.

Technical Insight SAMPLE CALCULATION FOR 7.5KW MOTOR The test results have been tabulated in Table 1 and Table II. Table 1 gives the values noted from the name plates like rating given by the manufactures and the rate speed and the torques noted at various speed. Table II gives the values for s obtained by use of Sm. Sm is the ratio of resistance and reactance for rotor as defined earlier. Sm = (1500 -1172) / 1500 = 0.2187
gives, s = 0.1760 = 1236 rpm Torque from the graph for this ‘s’ is 14 kgm Power delivered = (14 x 1236 x7.23) / 5252 (7.23 to convert into ft-lb) = 23.82 HP = 17.77kW Power at Tm or Sm=23.38 HP = 17.44 kW The experimental results have been obtained for the motors with ratings 0.75 KW, 1.1 KW, 1.5 KW, 2.2 KW, 3.7 KW, 5.5 KW and 7.5 KW Sample calculation and graphical representation is given only for a motor of 7.5 KW The power at slips worked out from equation (1) is 17.44 KW which is much higher than 7.5 KW.
CONCLUSIONS With the use of equation (1) derived above, it is possible to arrive at the full capacity of motor mathematically. The experimental results tally with the expression derived. The worked out ratings are found more than the ratings now adopted. The name plate ratings now given are less than what they could be. The manufacturers can safely project a higher rating on the name plate. Thus both manufacturers of the motor and the end user will stand to gain.

ReGen launches highest-capacity indigenous wind turbine suitable for medium and high wind regions. This wind turbine is expected to be ready for commercial launch by end of 2015. ReGen is also in the process of launching the next wind turbine based on Vensys technology for low wind markets like India and it is expected that a larger turbine with a rated capacity up to 3 mw with a rotor diameter between 110-120m will be ready for commercial launch in early 2016. ReGen Powertech has been in the Indian market for the last six years and has about 1,500 mw of installation in India and Sri Lanka eGen Powertech is working on India’s largest wind turbine WD 2.8 with a rated power output of 2.8 mw and rotor diameter of 109m. This is the largest capacity turbine with the biggest rotor diameter to be developed in India, a release by ReGen Powertech said. Entirely designed and developed by ReGen’s own R & D subsidiary in Germany, Wind Direct GmbH, this turbine has many unique design and constructional features. Primarily developed for the medium and high wind regions, this turbine is mainly intended for export to the emerging markets outside of the Indian subcontinent. It is expected that the introduction of this new turbine, a prototype of which is under testing in ReGen’s own test site in Coimbatore district of Tamil Nadu, will mark ReGen’s foray into the global arena. Wind Direct GmbH Germany, established in 2008, is fully equipped with software tools required for the design and development of wind turbine and has the competence to carryout load calculations, finite element analysis and detailed engineering and design of electrical systems including frequency converters. The permanent magnet synchronous
R
32 Electrical Monitor November 2014
generator of this turbine has very unique design and construction features and offers distinct advantage over the generators used in geared turbines as well as gearless turbines. The generator of WD 2.8 offers IP54 protection compared to IP23 protection normally available for generators of other gearless wind turbines. The generator is of segmental design and has two fully independent power systems, each of 1.4-mw capacity. This allows operation of the turbine at half the rated power in case of any maintenance to some of the segments of the generator. The unique design of the windings helps the generator to operate at a higher efficiency and also reduce the generator size and weight. The weight of the tower head mass is only 156 tonnes compared to almost 250 tonnes of other gearless wind turbines of comparable capacity and almost of the same weight as geared wind turbines of similar capacity. The generator has an active air to air cooling system which makes it suitable for operation in high temperature sites. The WD 2.8 MW wind turbine, whose prototype is under testing, is another feather in ReGen’s cap. This next generation product with its unique modular design is highly
behind it. It presently manufactures 1.5 mw synchronous permanent magnet gearless wind turbines with a technology agreement with Vensys Germany. In this short span of six years, ReGen Powertech has introduced wind turbines with three different rotor diameters of 77m, 82m and 87m suitable for low and medium wind regions found in countries like India. ReGen Powertech has two manufacturing facilities one in Tada, Andhra Pradesh with a capacity to produce 500 wind turbines annually and another in Udaipur with annual capacity of 200 wind turbines.

Good times for power sector
T
he power sector appears to be enjoying Acchhe Din under the Modi government during the first half of the ongoing fiscal 2014-15. Ex-bus power availability, broadly generation net of normative in-house auxiliary consumption, increased 8.6 per cent over the period, reversing the slide in the preceding two fiscals that had seen the growth rate go down from 8.8 per cent in 2011-12 to 5.9 per cent in the following year and a low of 5.6 per cent in 2013-14. Reflecting revival in the economy, power requirement, which had stagnated during the preceding fiscal, bounced back with 7.8 per cent increase during H1. The marked increase in power
34 Electrical Monitor November 2014
requirement notwithstanding, the deficit eased to 4 per cent, from 4.8 per cent in H1 of 2013-14 because of stepped up pace in power generation. In another pointer of better times, the period saw a decent 23 per cent increase in conventional power capacity addition. Cumulative power deficit over H1 is the lowest over past six-seven years, and the feat is remarkable as it has been achieved in spite of a decent increase in power requirement, a proxy indicator for economy expansion. The power sector’s feat is also distinctly better than that projected in Load Generation Balance Report: 2014-15

Across a variety of parameters ranging from generation to capacity addition, the power sector appears to have performed very well during the first half of the current fiscal year. As power is the all-important enabler of socio-economic growth, this good show could well be the forerunner of the much awaited Acchhe Din ahead, notes Dr M.S. Kapadia.

released in May last. Whereas power requirement has turned out to be 4.6 per cent higher than projection, power availability has surpassed projection by 5.3 per cent; which culminated in a lower average deficit of 4 per cent, as compared with 4.6 per cent projected in LGBR. The peak power demand-supply deficit was assessed at 4.7 per cent during H1, against 6.3 per cent in the similar period in the preceding fiscal, 9 per cent in the period two years back and double-digits in H1 of the previous four-five fiscals. Intra-period, the acceleration in the rate in power requirement was marked visibly after May; June-July recorded an average

increase of around 11 per cent and August-September 10 per cent, against 2 per cent during April-May. The growth rate in power availability was lifted from a low of 2 per cent in May to 12 per cent average in June-July and around 9 per cent during AugustSeptember. The government, focused on step-up in thermal generation, in view of fall in hydropower potential due to erratic and deficient southwest monsoon. By the way, the new government took reins in late May. The power deficit declined steadily from 4.4 per cent in April to 3.8 per cent in May, 3.7 per cent in June and 3.6 per cent in July, but increased to 4.6 per cent in August with the provisional estimate for deficit placing it at 4.1 per cent in September. Western region which accounts for 29 per cent of the country’s power needs escaped with only 1.1 per cent shortfall; all states falling in the region rendered them equitably well. In H1 of 201314 also, the region had suffered just 1 per cent power shortfall. Northern region with one-third share in the country’s power needs suffered 6.5 per cent cumulative deficit in H1; Uttar Pradesh and Jammu & Kashmir accounted for most of this deficit. Southern region with 26 per cent share had to bear with 4.9 per cent deficit; Andhra Pradesh (post bifurcation), Telengana and Karnataka were among the major deficit states.

comprising relatively small states suffered 9.6 per cent shortfall. There were five states, which escaped power deficit during H1; the major one in this category was Gujarat whose power availability of 47,642 million kwh fell only marginally short of its requirement of 47,665 million kwh during the period. In fact, the state had remained self-sufficient in its power needs in the preceding fiscal also. The major states with a shortfall exceeding the national average included Jammu & Kashmir (20 per cent), Uttar Pradesh (16.4 per cent), recently-formed Telangana (8.4 per cent), Andhra Pradesh (7.1 per cent) and Karnataka (5.5 per cent). Power requirement in the seven top states in terms of power demand increased 7.9 per cent, whereas its availability went up by 9.1 per cent over H1 on a y-o-y basis. Power requirement in Karnataka increased only nominally by 121 million kwh annually during H1, but power availability improved 2,139 million kwh, which resulted in sharp reduction in deficit to 5.5 per cent from 12.1 per cent a year ago. Likewise, deficit in Tamil Nadu also truncated from 6.6 per cent to 2.5 per cent due to subdued growth in power requirements, vis-Ă -vis power availability. Power deficit in Uttar Pradesh however worsened from 14.3 per cent to 16.4 per cent due to lower addition to generation.
POWER GENERATION The total power generation in conventional public utilities increased 10.3 per cent in H1, speeding from 5.7 per cent during H1 of 2013-14 and 4.8 per cent in this period two years back. The performance also surpassed generation

Among the fuel-based classification, power generation in coal-based thermal was up 14.8 per cent with IPP notching up 37.5 per cent rise. Central utilities expanded power generation by 6.2 per cent and state utilities, 11 per cent. PLF in coal-based Central utilities was the highest at 73 per cent against 63 per cent in IPP plants and 60 per cent in state utilities. Power generation in lignite-based plants increased 8.9 per cent. Overall, PLF was 64.9 per cent in coal-based plants and 76.4 per cent in lignite-based power, which, however, contributes only around 4-5 per cent in total thermal power. At 21,435 million kwh, the power generation in gas-based thermal power declined 6 per cent during H1; even as there was wide variation in the performance of individual power stations. Faced with dire gas shortage, the aggregate PLF at these stations worked out to just around 22 per cent. Power generation at diesel-driven stations increased 4 per cent to 905 million kwh. PLF at nuclear power stations improved to 80 per cent from 76 during H1 of 2013-14. Among the ownership categories, power generation at Central government-owned utilities increased 3.9 per cent during H1; that under state utilities 7.3 per cent and the same under private sector 27.2 per cent, bulk of it under IPP that shot up 31 per cent. In fact, private sector public utilities recorded 2.8 per cent decline in generation. Overall, Central utilities accounted for 38 per cent of power generation during H1, state utilities 35 per cent and private sector the balance 27 per cent. Among the regions, generation in northern region increased 7.3 per cent during H1, the same in western region was up 18.2 per cent due to much better feat by thermal stations in the region. Power generation showed 6.3 per cent increase in southern region and eastern regions. Power generation in north-eastern region showed 14 per cent increase.

CAPACITY ADDITION The first half of the ongoing fiscal has seen addition of 8,978 mw under conventional power capacity, exceeding the 7,274 mw addition planned for the period. The feat was made possible because of private sector thermal capacity addition surpassing the target. Also, taking the first half of the ongoing plan period, the picture is reassuring. Thus, with an augmentation of 47,426 mw over the period, the period has seen achievement of 53.5 per cent of the target of 88,537 mw fixed for the five years plan period. Thermal power addition for the period was assessed at 45,600 mw and hydropower at 1,826 mw: nuclear power has drawn blank. On a broader canvas, the country had aggregate generation facility of 254,050 mw at the end of September 2014; comprising 176,778 mw in thermal power, 40,799 mw in large hydro, 4,780 mw in nuclear power and 31,692 in rapidly increasing renewable energy sources (RES) like small hydro of less than 25 mw, biomass, solar energy, urban & industrial waste power, wind energy, etc. Captive generation capacity in Industries having demand of one mw and above, grid interactive added (as on March 31, 2012), another 39,375 mw. As a result of an accelerating RES, its share in total installed capacity has shot up to 12.5 per cent at the end of September, from 5.9 per cent in March 2007. Small hydro constitutes 3804 mw, wind power 21,136 mw, bio-power 4,120 mw and solar power 2,632 mw in RES. The share of coal based thermal power capacity in conventional power has gone up to 69 per cent from 57 per cent in 2006-07, while that of hydro power has gone down 28 per cent to 18 per cent, gas-based from 11 per cent to 10 per cent and nuclear from 3 per cent to one per cent. Diesel based capacity has stagnated at 1,200 mw.
Helped largely by non-conventional sources of energy the private sector accounted for 36 per cent of total grid interactive capacity, state sector 37 per cent and central sector the remaining 27 per cent, as of September 2014. Almost 90 per cent of RES falls in private sector, wherein it accounts for 30 per cent of capacity. Looking at recent trends, private sector would soon become the major ownership segment in power infrastructure facilities. Western region led other regions in terms of power infrastructure. The region accounted for 35 per cent of total installed capacity in the country, as of September 2014, followed by northern region (27 per cent), southern region (24 per cent), eastern region 12 per cent and north eastern region and islands just around one-two per cent. Western region was ahead in thermal power capacity, northern region in hydro power and southern region in RES. Among the states, Maharashtra led with 35,827 mw of overall power generation capacity, followed by Gujarat 28,422 mw and Tamil Nadu 21,193 mw, as of September 2014.
RENEWABLE ENERGY SOURCES According to Ministry of Renewable Energy, a total of over 53.22 billion kwh were produced during 2013-14 from renewable energy sources in the country, which included 31.26 billion kwh from wind, 3.35 billion kwh from solar, and 12.32 billion kwh from biomass and bagasse cogeneration. Small hydropower (with installed capacity less than 25 mw) contributed 6.06 billion kwh to the total power generation. MNRE has set a target of capacity addition of 29,800 mw from various renewable energy sources during the 12th Plan period. The target comprises 15,000 mw from wind, 10,000 mw from solar, 2,100 mw from small hydropower and 2,700 mw from bio-power.

Schneider Electric, a global energy management company, has been historically engaged in manufacturing of products used in electrical infrastructure. The company's Indian arm forayed into the solar business in 2010. Schneider Electric India manufactures solar inverters at its 1.4 GW capacity state-of-the-art manufacturing facility in Bangalore. In addition to meeting the demands of the Indian solar market, the manufacturing facility exports to several countries across the globe. Anurag Garg spoke to Debdeep Chakraborty about the company's offerings in solar and also some of the crucial issues that confront the Indian solar sector at present.
‘
We are a long-term player in the solar industry
— Anurag Garg, Vice President, Solar Business - India, Schneider Electric India Pvt Ltd
Take us through Schneider Electric's offerings in the solar (photovoltaic) business, both globally and in India. As far as solar offerings from Schneider are concerned, whether globally or in India, we operate in two verticals. One is the utility scale and large commercial and the other is roof-top and small commercial. The utility scale and large commercial primarily covers solar farms that are in MWs, and large commercial rooftops of 500 kW and above. In the other vertical, which is the roof-
top and small commercial, we have products that go into a roof-top system such as inverters, charge controllers and communication devices as well as offerings for small commercial which includes individual houses and some solutions for telecom towers. Globally, we offer some solar products for mobile (transport) applications. We have an offer under the mobile category for trucks operating on long distances but it has not yet been deployed in India. However, there is considerable focus on it in some other parts of the globe. In terms of products on offer, Schneider as an electrical company has been historically manufacturing products and solutions required in any electrical infrastructure such as transformers, switchgears, relays and control panels, distribution management systems etc. In solar, we have inverters—large sized for farms and small sized for roof-tops and small commercial. We have been manufacturing these inverters in India since 2012. Our large sized inverters are grid compliant. We were among the early ones who began manufacturing the solar inverters in India, not only for India but the global market. The plant in India is a global plant which makes inverters for countries across the globe, be it US, Japan, Australia or Europe. So, from the perspective of Indian customers, it is a big advantage to have a global product being sold from an Indian manufacturing set up at a price aligned to the Indian market. Tell us more about your solar inverter substation. Yes, we also have a very innovative solution called a solar inverter substation. Again, we were the first one in India to provide this

Interview: Schneider Electric enabled. Our thrust is on how we can use the Indian manufacturing capability and capacity for Indian market and also for export. What is your view on the thrust being provided to the Indian solar industry by the government's National Solar Mission? We have started at a slow pace. If compared to China and Japan, we are not at the same speed, but in my opinion, it is better to go slow initially. What is important is that the government's policy announcements clearly reflect that we cannot stay with the same speed. Having experimented we know that everything is fine and now we can ramp it up. The government is aware that we are not up to the speed. It is however not the end of the road. We have the capacity, capability, land and irradiation. So, it is only a matter of time before we catch up. The announcements made by the government clearly indicate that solar has to happen. The recent announcement by the government says that we have to do 5 to 7 GW per year from 2017. I am sure the government means it. The government is not saying that we have to do 5 to 7 GW from tomorrow as they know it will take time to ramp up the capacity. The government is also inviting foreign manufacturers to come and set up the facilities in India to ensure capacity build up for the growth that we are planning. Do you think that India's target of attaining 20 GW by 2022 is tenable? What are the key challenges en route? I am quite confident that we would be able to achieve the target earlier than that. As far as challenges are concerned, I would point to some of the state policies. For example, Andhra Pradesh came solution to EPC and developers. In this solution, everything comes in a container including transformers, switchgears, UPS, auxiliary transformers and the control panels with all necessary safety precautions. We call it a Plug N Play solution. As you know, solar projects are set up in remote areas having harsh conditions, the Plug N Play solution for large solar farms helps developers and EPC complete solar projects within a short cycle time with many other benefits of reduced site activity and elimination of the need for coordination with various suppliers. Since it is a pre-tested solution, only the cables have to be connected and the evacuation can be done within a fortnight after arrival of the sub-station. We also offer a solution for monitoring the performance of the solar plant. Again, it is a global solution and deployed for Indian customers also, if required. So in a nutshell, it can be said that beyond solar panels, and maybe cables, Schneider has a portfolio of products to support the solar industry. We are not a full EPC but we do have project capability given the background of a project oriented company. As far as roof-top and small commercial goes, we have offers covering various solar needs with MPPT charge controllers of various ratings and inverters suitable for battery based and non-battery system for single and three-phase. Our offer of charge controllers is widely used in telecom towers which have started using solar power to off-set diesel thereby reducing OPEX and also CO2 emissions. On the hybrid side, we have launched a product with some upgraded features since people want to use solar as much as possible against diesel. We already had the product on which we carried out upgradation of some of the features. The good thing is that our products are net metering

out with a 1,000 mw tender but due to division of the state, the process slowed down. The government has understood these kinds of challenges. It has tried various models such as VGF and bundling. We are now again back to bundling under which NTPC and NVVN will be consuming the solar power generated. So, these impediments that are coming from here and there actually constitute the learning process. The government knows how to move forward. Discuss how changes in photovoltaic technology have brought down capital costs of PV plants? Capital costs come down as a result of high efficiency products and pressure on the market. It has been possible to bring down the capital costs with the help of EPC companies supported by suppliers. Companies have worked on their productivity measures as well as the technology of their products. As compared to the

Interview: Schneider Electric time when the Gujarat solar story started, the tariffs in the market today are significantly lower. However, we can't expect the same percentage of reduction going forward but the tariffs are going to reach a level at which solar will achieve grid parity by 2016-17. We are not competing with wind which is cheaper but the objective is to make solar a viable energy source with all the benefits of clean energy. Financing remains one of the major challenges for solar power projects as domestic banks perceive significant risk in solar investments. Given that the growth of the sector is linked to domestic lending, how is the industry planning to overcome this challenge? The sector is already overcoming this challenge. Government funding agency IREDA is financing solar. Government has said that it will support financing. It is understood that financing is one of the hurdles and the issue is being addressed in the policies of the government. Confidence building takes time in any new industry that evolves. Nobody wants to put money in something that is not proven. Going forward, the way the government is addressing this issue and also taking into account the performance of the solar plants that have already been commissioned, the financing community is getting the confidence back. The point is that the power sector, and not solar per se, is facing financing issues. Solar is part of that sector in financial institutional allocation. The way solar has established itself, the way government is trying to build confidence, and the way the government is trying to bring companies to India to manufacture, will go a long way in boosting the confidence of financial institutions. Global companies such as Schneider have already come to India and are manufacturing. JNNSM, apart from targeting solar power capacity, aims to create a manufacturing base for solar power equipment in India. What challenges do you see ahead? There are no challenges. We have not faced any challenge. It was our choice to come here and manufacture. We realize that India is the right place for manufacturing a global product and also help the Indian market. We never faced impediments from the government's side. So, if companies want to reap the benefit of the growth of Indian market, they need to come and invest. There are no impediments. In Batch I of the second phase of JNNSM, out of the 750 mw of capacity allocated, 50 per cent had been reserved under the domestic content requirement category. However, solar power producers claim that there is insufficient domestic capacity. What is your view? We do not track the solar cell and module industry from that perspective. I hope the 375 mw allocated under the DCR category is commissioned, and if it gets commissioned, it goes to prove that sufficient capacity is available.
46 Electrical Monitor November 2014
Many domestic manufacturers are pushing for anti-dumping duty on solar equipment imports from USA, China, Taiwan and Malaysia. Do you think such a measure will help boost domestic solar manufacturing? I don't think so. On this front, government has already assured manufacturers that their capacity will be consumed. While giving that assurance, it has been made clear that manufacturers need to be competitive at the same time. Some of these manufacturers are also exporting out of India. It is in the interest of the industry to support growth as well as protect local manufacturing. In any case, the government is asking global manufacturers to come and invest in India. Those opposed to anti-dumping duty on import of solar cells and modules claim that it will impact the success of NSM. What is your stand on the issue? That chapter is already kind of closed. The reason possibly is that the government wants to assure of capacity consumption and at the same time does not want to slow down the industry. There is intent to protect the industry but at the same time not block the industry which is the growth of solar plants. Do you think solar power will attain grid parity in the foreseeable future? I will go with research done in this regard. Research says that solar will achieve grid parity by 2017. While thermal power will go up, solar is already showing a reducing trend. Solar has already achieved grid parity in some places where commercial tariffs are very high. Generally speaking, a capital-intensive industry like solar needs government support for its sustainability. What is your take, especially in the Indian context? I think an industry has to be self-sustainable in the long term. The government can only provide temporary support to ensure that the industry is growing. With maturity, the industry has to become self sustainable like any other sector. The government is at present supporting the solar industry with the objective of addressing the various issues at hand. The same is not being done for every industry. The government will not be there forever to support. It is the responsibility of all stakeholders to see that the industry becomes self sustainable in the long term. Tell us how you see the years ahead for Schneider Electric's solar business in India. Schneider is a very innovative company. We invest about 4 to 5 per cent of our revenue on R&D globally. We try and align ourselves with the demand and growth that will be there in the future in terms of technology, efficiency etc. We are a very dynamic organization and align ourselves with the changing environment and needs and demands of customers. I would say that we are in solar, we are going to stay in solar and we are a long-term player in solar.

DEIF's Solar Solutions
A
mong the renewable sources, solar power is gaining momentum in India with the push given by government and the abundant solar potential. The increasing demand is driving down the cost of solar energy which is attracting more and more investment in this sector. While the investment and increasing of solar share in the energy sources is fully justified, it is also equally important 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 utilized 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 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 with its experience and expertise in the field of power generation control solutions; has come up with an innovative solution to this challenge. DEIF introduces the Advanced Solar Controller (ASC), a
solution that provides integrated solution for systems with utility, diesel and solar power source. 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 or central control point 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. Savings: To get a glimpse of what you would be your minimal saving after installing DEIF's solution, let us consider a simple real life example. 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 (500 KW at full load) and assuming $1.5 per litre as cost of diesel, for 1000 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 to this, the cost for handling the fuel, managing resources, maintenance of genset, gas emissions, and environmental setbacks add to the overheads. On the other hand, DEIF's solar solution enables you to use solar power even in the absence of utility with high solar penetration. Say with a 60 per cent solar penetration you 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 maximize the project's overall return on investment. DEIF's solar solution will thus prove to be a boon to India's evolving solar sector. For more details, write to india@deif.com

Eberhard Ritzhaupt-Kleissl
Siemens is a leading player in the solar power industry offering a slew of products and services for both solar photovoltaic and solar thermal plants. Siemens is also active in the EPC business for ISCC power plants (Integrated Solar Combined Cycle), where it can provide full EPC/turnkey capability for such plants including the rather complex task of integrating the CSP and CCPP parts. In this exclusive exchange, we have Achaz von Arnim and Eberhard Ritzhaupt-Kleissl, respective experts in the photovoltaic and solar thermal sector, taking us through Siemens' competence in the solar power industry. With respect to the Indian market, Siemens has a clear focus of increasing local content and ensuring that it is always closer to the customer. An interview by Venugopal Pillai. Can we start with a summary of services offered by Siemens in the solar power field? Achaz von Arnim (AVA): Generally Siemens offers all kind of equipment for thermal solar power plants and is the market leader with steam turbines for this application. Siemens also offers the entire automation, process optimization and electrical equipment/solutions among CSP power plants supply chain including ISCC (integrated solar combined cycle), from steam turbine to balance of plant (BOP) and solar field.

Eberhard Ritzhaupt-Kleissl (ERK): In the field of photovoltaic (PV) Siemens offers photovoltaic power plant layout planning with a dedicated tool called PVplanet (PV Planning and Engineering Tool) to provide best possible layouts for certain customer needs. This ensures lowest LCoE, lowest capex, highest yield, highest installed capacity, among other things. It also provides onsite and remote services for PV-plants that include operation and maintenance, corrective maintenance, preventive maintenance, etc.
Electrical solutions that Siemens also offers comprise eBOP "electrical Balance of Plants" like transformers, switchgears, UPS as well as field devices (like current sensors, weather stations, etc) for PV and CSP. Please discuss in general the importance of a control (integration) system in a solar thermal power plant. AVA: Siemens is the only company with a harmonized control system SPPA-T3000, since Siemens supplies the steam turbine with SPPA-T3000 as well. CSP plants are characterized as steam power plants with a fluctuating fuel (varying intensity of the sun due to clouds, rain etc.) Solar fields designed for 50-mw cover approximately 2 sqkm and therefore even small clouds can have an impact on the heat transfer fluid and on the quality of the steam. In order to avoid trips or shutdown of the steam turbine, fast changes needs to be buffered by an optimized control system. A harmonized control system provides seamless integration of e.g. a steam turbine into the BoP of the surrounding solar field.

Interview: Siemens Solar dispatching. Both solution are successfully adapted from fossil power plants and have been implemented at the 50-mw Lebrija CSP project in Spain. Does Siemens provide control systems for only solar thermal plants? ERK: Siemens also provides control systems for photovoltaic power plants. This solution is based on the same system as for the solar thermal plants. For this, we use the world leading power plant automation system SPPAT3000 (Siemens Power Plant Automation T3000). For photovoltaic plants, Siemens has big utility installations up to 50 mw as well as smaller utility-scale installations with about 5 mw in several countries. Since SPPA-T3000 is installed in different kinds of power plants (solar and other forms of renewable energy), customers with multiple assets can use the same framework of automation solution for their entire portfolio.
What are the key markets (countries) for Siemens with respect to its solar control system business? ERK: For PV every country or region with the need for a professional power plant automation system for renewable power sources (solar, wind, etc) can be a key market. AVA: For CSP, the key markets are countries in the tropical sun belt region. Main markets for CSP have been in USA with references like Ivanpah 3x133-mw (largest solar tower with SPPA-T3000 of ST) and Genesis 2x150-mw (first harmonized control system SPPA-T3000). Spain is a typical 50-mw market with references like Andasol III and Lebrija. Other upcoming markets are South Africa, India, Morocco, Egypt, United Arab Emirates, Kingdom of Saudi Arabia, Chile and Mexico, among others. Regarding its solar business, does Siemens have a presence in India? How do you see prospects from India given the ongoing thrust on solar power?
ERK: Siemens has a setup of specialists, software as well as commissioning and project execution capabilities, for renewable (especially solar power and PV solutions) in India. Based on the strong Indian setup, Siemens serves the adjacent regions and markets. Since the Indian market for renewable power is growing rapidly, Siemens considers it essential to serve this market accordingly. The main goal is to increase the local content and be close to the customer. Note: Even if Siemens has decided to discontinue an own CSP business in house, Siemens manages the integration of the CSP part of an ISCC plant from the most suitable vendor. Furthermore, Siemens is active as an EPC for megawatt scale PVHybrid power plants, i.e. combining an (existing) diesel engine e.g. with a PV installation and a battery storage to allow the power producing entity to lower their fuel consumption-their operating expenditureand thus realize tremendous savings.

We believe that India can attain 20 GW of solar capacity by 2022
Tell us about your partners EDF and EREN, and their specific expertise in furthering ACME Group's business. EDF and EREN are strategic and financial investors in ACME Solar Energy Pvt Ltd. Our joint participation has helped us in streamlining the project management process. ACME has been a pioneer in creating disruptive innovations, large-scale project management and large-scale 24x7 O&M which is helping us to create differentiation in the market. What is the current status of the 30-mw solar project in Chhattisgarh that ACME Solar had won earlier this year? ACME Solar won a 30-mw solar PV power project under RfP floated by Chhattisgarh State Power Distribution Company Ltd. The letter of intent (LoI) has been issued to us. PPA will be signed in November 2014 and project activities will be started immediately thereafter. What is the total portfolio of ACME Solar, including installed and under construction? ACME Group has the current portfolio of over 400 mw out of which 40 mw is operational, 125 mw is under execution and the remaining projects at various stages of preconstruction development activities. What is your target for, say, 2020? Our target is to set up 1 GW solar photovoltaic projects by 2017. We observe that ACME Solar also provides EPC services for

other solar power developers. Tell us more about projects (contracts) under execution. Yes, we provide EPC services to other solar project developers. We are independent power producers (IPP) and we offer buyback option also at agreed price to the investor. We build plant as if we own them and have to run for 25 years. This is a great option for the investor to cash out as and when they need liquidity. Please discuss the two major solar power technologies— photovoltaic and solar thermal—in the context of their capital costs, engineering challenges and their relative importance to India's solar power ambitions. Photovoltaic technology has achieved a status of lenders

confidence as well as certainty on the project cost, implementation period and zeroing down the technology risk. On the other hand, solar thermal is way behind in achieving comparable status. The main challenge faced by solar thermal technology is low DNI (direct normal irradiance) in the Indian subcontinent, making the technology commercially and technically unviable at most of the places. Moreover, visibility factor and cloud transients make the business case more difficult in India. These challenges are accompanied with high cost of technology and storage solution. Innovation in technology and indigenization of critical components may revive the growth of solar thermal in the near future. What is your overall view on the achievement of India under the Jawaharlal Nehru National Solar Mission (JNNSM)? What policy framework could further boost solar power capacity in India? It has been great success under JNNSM and various states forward looking approach to use solar as peaking power. We believe that measures like clear policy with feed-in tariff which will expedite the implementation of the solar projects across the country. Creating land banks across the country to be leased out for solar project development will drastically induce the growth of solar power projects in the country and also reduce the time of implementation of the projects.
Rigorous policy framework towards fulfillment of solar purchase obligation backed with stringent penalties for nonachievement of the same. Regarding financial support, solar should be given a different-sector status, so that the repercussion of power sector will not impact the financing of the solar projects. Solar PV should be introduced in the priority lending, thus facilitating cheaper cost of debt funds. Further, creating a clean technology reserve from international institutions like World Bank, Asian Development Fund, Japan Bank for International Cooperation etc. through sovereign guarantee mechanism, will provide cheaper debt funds for the solar projects. What is your view on falling capital costs of solar power equipment? How would it impact Indian solar achieving "grid parity"? Solar power cost is already nearing grid parity if you compare its power generation profile with peaking power plant. We believe the interest rate correction, exchange rate correction and new photovoltaic technology like more efficient solar panels will take solar power cost to the level where even conventional power will find difficult to compete! The government has been advocating "domestic content requirement" under JNNSM. Do you think local suppliers are equipped to supply the required quantum of solar power equipment? Government has created a win-win situation for developer and domestic manufacturer to offer right tariff point to the end consumer. Reserving some portion of total capacity will definitely help local manufacturers in upgrading their technology and competing at global level. How do you see the progress made by the Indian solar power industry so far? Do you feel that the target of installing 20 GW of installed capacity by 2022 GW is attainable? It has been a remarkable journey. We believe that 20 GW of installed capacity is definitely achievable by 2022.We believe huge upside if microeconomics as mentioned above can help to reach the threshold tariff of Rs.5.50 per kwh, and create exponential growth.

Established in 1979, Indore-based Ujaas Energy Ltd (formerly M&B Switchgears Ltd) is India's first company to install a solar power plant under the Renewable Energy Certificate (REC) mechanism in March 2012. The company has started an innovative offering called 'UJAAS Park ', that provides complete plug & play solution to the investor for putting up a solar power plant. Taking us through the company's gamut of solar activities, Vikalp Mundra exudes confidence of a bright future for solar power in India. An interview by Venugopal Pillai.
‘
Stricter enforcement of RPOs can boost solar industry
Ujaas Energy was the first company to set up a solar power plant under the REC mechanism. What is your view on the overall progress that solar RECs have made in India? The REC mechanism is the only way by which small and medium business can invest in solar. Other routes are generally meant for big investors with some previous experience. The new government has recognized the importance and relevance of the same and CERC already started a process to repackage the Solar REC price to a level of Rs.3.50 to Rs.5.80 per certificate. This was much needed. Now, with an Average Power Purchase Cost (APPC) of around Rs.6.50 (which is Rs.3 plus REC Rs.3.50), this is a financial viable solution for low resource regions and truly represents the benefits of REC Mechanism. We hope the final order from CERC should come by end of December and we hope that the REC mechanism is revived very soon. You had set a target of adding 200 mw of solar capacity in FY15. How has been the year so far? This year was lagged behind because of two reasons. First, the antidumping duty on solar modules was achieved only on August 22 this year, and two, the poor enforcement of renewable purchase obligations (RPO). With our Hon'ble Prime Minister, who is an avid supporter of solar, we hope that the RPO enforcement issue will be finally pushed through. The government is also working on some more things like renewable generator obligation (RGO) that will push

solar even more aggressively. What is the currently the cumulative solar power capacity owned by Ujaas Energy? As of now, the Ujaas umbrella has 108 mw ground-mounted solar power plants and about 2,000 KW rooftop installations pan-India. How has Ujaas been faring with respect to setting up solar power plants for other companies? We were the innovators of the solar park concept in India, which is been very successful as our customers are non-energy companies. Ujaas Park provides them with a one-stop solution for their solar projects. They just remain passive investors and need not to invest their time and energy for their solar pursuits. So, it is a very successful model of business for Ujaas as well as for investors.

How do you gauge the performance of the National Solar Mission so far? The new government has revised the target of grid-connected solar capacity to 100 GW by 2020. Hence, India is moving very aggressively on the solar front. And we are confident that this government is serious about it, and the movement on the ground is in that direction only. Till date approximately 2.6 GW is installed in India, in my conservative estimate by end of 2015, almost 5-7 GW more would be added or would be in pipeline. We hear of domestic content requirement (DCR) regulations under JNNSM. What is your overall view? Do you think India is equipped to handle the demand for solar cells/modules without resorting to imports? DCR is a very logical step, and if you read introductory document of JNNSM, it says that this aims for local manufacturing too. This is a very welcome step and it will definitely move India to increase and add new capacity of solar cells and modules. And what can be a better timing for this as our Hon'ble PM has
already launched "Make in India" program. I am confident that by 2016, India will have 1 GW - 1.5 GW domestic manufacturing capacity. Here, one thing that is to be understood is that DCR is reserved up to the extent of capacity available. The aggressive target of 100 GW can be achieved only by keeping all the doors open. India was planning to impose anti-dumping duty on solar cells and modules imported from China. What is your take on the matter? This matter was put to reset on August 22, 2014. I have always held that DCR is a better way to do it. In an overall sense, what policy changes can spur the growth of solar power in India? I think the present government is really acting with good intent, but as a wish list, I would recommend strict enforcement of RPOs; net metering policy for all states to promote rooftop; low cost loans for rooftop; classification of loans to solar industry as as priority sector lending; fast implementation and removal roadblocks for solar projects with utmost priority.
SOLAR BRIEFS Central PSU NHPC will set up its first solar project in Uttar Pradesh, with an estimated cost of Rs.400 crore. NHPC signed a promoters’ agreement with Uttar Pradesh New & Renewable Energy Development Agency for setting up a joint venture company for implementation of solar power projects in Uttar Pradesh on October 17, 2014. The project is scheduled for commissioning by mid-2016. An initial pact for this 50-mw was signed between NHPC and UPNEDA in August 2013. Medha Energy is planning to set up a solar-based power unit at Bhetala, in Jalor district of Rajasthan. The 20-mw photovoltaic project, coming on 80 acres of land, will be set up with an investment of Rs.174 crore. Around 75 per cent of the project cost will be funded through bank loan and the remaining 25 per cent from internal accruals. NTPC is setting up a 750-mw solar photovoltaic project in Madhya Pradesh, for which an MoU was signed recently. The project will be set up at Rewa district with an investment of Rs.5,000 crore. The solar project will be completed in three tranches of 250-mw each. NTPC has set a target of generating 3,500 mw through solar power in the next few years.
Of this 1,000 mw will be in Andhra Pradesh, Telangana and Rajasthan; land identification is currently underway. Solargise plans to set up 3,000 mw of solar power projects, which includes those as developer and as EPC contractor. They will be completed in the next 2-3 years through its Indian subsidiary, Solargise GRAPP Energies. The cost of the solar projects is estimated at Rs.1,200 crore. Solargise has already secured a few projects across Rajasthan and Bihar under the state government’s mission plan. In addition, it is in the process of securing a few more projects in Andhra Pradesh, Karnataka and Tamil Nadu. The company is also developing a 200-mw project in Gujarat. ACME Group, the leading green energy player in India, announced that it has received final approval for credit facility of $100 million loan from Asian Development Bank. The proceeds of the loan shall be received in multiple tranches. The first tranche of $50 million shall be utilized in developing 100 mw projects in Rajasthan and the remaining amount of loan shall be used for its upcoming projects.

As just one of its wide range of activities, DuPont does continuous innovation, research and development to make solar energy more competitive with other sources of electricity. DuPont has developed two solutions—Solamet® metallization pastes and Tedlar® polyvinyl fluoride (PVF) film-based backsheets—that have improved efficiency and longevity of solar modules. We have Rajaram Pai discussing these innovations and how they can contribute positively to India’s solar growth story. An interview by Venugopal Pillai.
‘
Project developers are getting conscious of efficiency — Rajaram Pai, Business Leader—Electronics & Communications, South Asia, DuPont
From a technical perspective, tell us how DuPont™ Tedlar® filmbased backsheets help to improve the performance of solar panels. The backsheet is a critical outer layer of the solar panel that protects the sensitive solar cells and circuitry inside the panel from moisture, UV rays and other environmental stress. It also provides electrical insulation to help ensure the panel’s safety. If a backsheet fails, or degrades faster than it should, the panel’s performance can quickly be compromised, causing potential safety issues and either complete failure or premature power degradation. That is why one of the most important ways to help ensure long term durability of solar panels is by specifying Tedlar® film-based backsheets for solar panels. Tedlar® film is the only backsheet material that has been proven to protect solar panels in the field for more than 30 years, even in extreme environments. Put simply, Tedlar® film-based backsheets help ensure safe and reliable power output for the expected life of solar panels, and in many cases, longer. Is the rate of conversion of light to electricity in a Tedlar®-treated solar cell/module significantly higher than an untreated one? Tedlar® film-based backsheets protect the ability of the solar panel to deliver power safely and reliably over its expected 25year lifetime, or even longer. Backsheets themselves do not determine the conversion efficiency of solar cells or the power output of the solar panel, but they can help effectively maintain it over time. Greater power output from solar panels is enabled by several
56 Electrical Monitor November 2014
factors, including the design of the solar cell, and its conversion efficiency. The conversion efficiency of solar cells is determined primarily by the use of metallization pastes. DuPont™ Solamet® photovoltatic metallizations are designed to help boost the efficiency of the solar cell. In fact, over the past 12 years, successive generations of Solamet® pastes have helped nearly double the efficiency of solar cells, improving solar panel power output. Is it possible for Tedlar to be retrofitted on existing solar PV plants? No, it is not possible to retrofit solar panels with Tedlar® filmbased backsheet, which is why it is critical to specify Tedlar® film-

Interview: DuPont based backsheets in advance of ordering solar panels to help ensure their reliable long term performance. Once solar panels are delivered, it is also recommended to verify that Tedlar® film was in fact used! Apart from Aditya Birla Solar’s 20-mw Rajasthan solar power project, has DuPont supplied to any other project in India? Yes, advanced materials from DuPont such as Tedlar® film and Solamet® metallization pastes have been used in a number of installations in India. We have a number of key collaborations with leading solar companies including Aditya Birla, Tata Solar Power, Lanco Solar, Moser Baer and others. Tell us about the cost of treating solar panels with DuPont™ Tedlar® film. Because Tedlar® is the only backsheet material proven to protect solar panels for 25 years or more in the field, even under extreme weather conditions such as those we find in India, Tedlar® filmbased backsheets tend to have a higher value than unproven materials. For a few cents more per panel in most cases, Tedlar® film-based backsheets help solar panels maintain optimal power output safely and reliably over their lifetime, improving return on investments in solar energy systems. Is DuPont Tedlar® film meant for application in India (tropical climate) or does the product have a global appeal? Tedlar® films have set the standard for backsheet performance worldwide. Even in mild climatic conditions, a solar panel goes through a lot of environmental stress over a period of 25 years or
longer. To minimize the risk of panel failure or premature power degradation, durable and proven materials are critical. DuPont has conducted field studies worldwide, and found that unproven and inferior materials are failing in as little as a few years, even in Europe where the climate is much less challenging than in India. Thus, irrespective of the climatic conditions, it definitely makes sense to use proven materials such as Tedlar® film. While in milder climates a single layer of Tedlar® in the backsheet may be suitable, for especially challenging environments such as in India, we recommend a double layer of Teldar® film in the construction of the backsheet. Given that India is vigorously pursuing solar energy through the National Solar Mission, how do you see business opportunities for DuPont™ Tedlar® and other solutions to improve performance of solar power plants? With rapidly increasing growth in the Indian solar market for installations as well as manufacturing, there is a huge opportunity for the industry. There has been a significant change in the mindset of project developers and others who have become increasingly conscious of the importance of optimizing both the power output and durability of solar panels to improve the return on investments for projects. They are better understanding the critical role that materials such as DuPont® Tedlar® films and Solamet® metallization pastes play, and are willing to invest in quality materials to get reliable returns. As Tedlar® and Solamet® are synonymous with improved power output and long term reliability; there are indications of strong growth in demand for advanced photovoltaic solutions from DuPont in the coming years.

GE Techmela: Innovation at its best n impressive array of innovations from various business groups of GE epitomized the two-day "GE Techmela" held recently at KPTO's Exhibition Centre in Bangalore. The collective effort of 5,300 researchers, scientists and engineers of Bangalorebased GE India Technology Centre (GE ITC) was showcased in what could be described as a colossus of ingenuity. Innovations on display spanned the main businesses of GE—healthcare, aviation, transportation, power & water, oil & gas and energy management. GE ITC, formally known as John F. Welch Technology Centre, was founded in 2000 and has over 4,500 scientists and engineers working on innovative technologies for all GE's business. The GE Power & Water business showcased several technologies for power generation that included mainly gas turbines wind turbine generators. Interacting with Electrical Monitor, GE officials explained that the company's focus has largely been on clean energy. It is worth observing that it was GE that set up India's first hydropower plant; it did so way back in 1902 when it commissioned the 4.5-mw plant at Sivasamudram in Karnataka. While coal-fired power plant technology has not been GE's principal focus area, it has done much work in cleaner gasfired power plants. On display was the J316 engine with a rated output of 834kW and efficiency of 40 per cent.

The versatile engine can be fired using a diversity of fuel including natural gas, flare gas, biogas, propane and even landfill gas. GE engineers also highlighted that GE has developed the 9HA heavy duty gas turbine. With capacity of nearly 400 mw in opencycle mode, it is currently the highestcapacity gas turbine in the world. Speaking of wind energy, GE officials explained that development work was in progress for a wind turbine with 1.7mw rated capacity and a rotor diameter of 103m. This turbine would be most helpful for low-wind regimes in India. GE has so far installed 227 wind turbines in India, mainly in ratings of 1.5 mw and 1.6 mw, officials said. Research relating to wind energy is
Wireless power transmission highly innovative product that GE has been working on intensively is wireless transmission of electricity. GE-ITC has developed the prototype of an assembly that can transmit electricity without conductors albeit over small distances of around 15cm. GE engineers explained that wireless transmission was ideally suited for charging of electric vehicles. The assembly has already been tested on the campus of GE-ITC, officials said. Over the recent past, GE has made significant improvements to the wireless charger. In its latest form, the appliance to be charged (load) can be placed even at longer distances than before, and even at an angle. This feature of flexibility of distance is best suited for electric vehicles. In the latest version of the charger, minor deviations in the position of the vehicle with respect to the charger would not affect the charging process, officials explained.

done at the Pune wind facility that was established in 2010. Amongst the research work currently underway was to "connect" all these wind turbines over the Internet to study their performance—individually and collectively. "Monitoring of existing equipment goes a long way in product development," a GE engineer said. A key area on which GE is doing significant research was 3-D printing— a term given to fabricating monolith items out of suitable raw material like polymer. Currently, small components are fabricated, but in future, GE will be able to "print" even large components and that too from a variety of raw material, including steel. When 3-D printing escalates to a higher scale, it would be possible for GE to fabricate big components even of large equipment, like gas turbines. The GE Global Research Centre is also working on making wind energy management more efficient through a variety of measures. A GE official explained that wind energy tends to be erratic by nature and hence needs to be made more controllable so that imbalances in the grid are kept under check. In some countries, there are regulations in place that penalize or incentivize grid operators based on their contribution towards grid discipline. In the case of wind farms, power generated cannot sometimes be absorbed by the grid as there is low

A clear focus on clean energy nteracting with a group of select media, Mariasundaram Antony, General Manager, India Engineering Operations, GE Power & Water, summarized GE's offerings in the power generation segment. He highlighted that GE was one of the oldest players in steam turbine technology with solutions for fossil-based fuels, nuclear power plants and mainly for gas-fired (combined cycle) power generation plants. GE's overall focus is generating clean energy by keeping carbon emissions low. In the renewable space, the emphasis has been on wind energy where GE provides end-toend solutions like site identification to manufacturing of wind turbines to setting up of wind farms. Mariasundaram explained that for a country like India, dependence on coal-fired power plants is inevitable. However, even coal-based power plants could be made cleaner through different technologies. He explained that supercritical technology where emissions are lower and efficiencies higher is the way forward for India. On GE's contribution to clean coal technology, Mariasundaram noted that GE has developed coal gasification technology where instead of burning coal, it is converted into gas. This gas is then used to generate electricity. Though the capital costs of an integrated gasification combined cycle plant (IGCC) are on the higher side, there is tremendous benefit in terms of lower carbon emissions. "GE has the entire system-the gasification system along with the combined-cycle technology," Mariasundaram said. While India is making some progress on setting up IGCC plants on a pilot basis, there is emerging demand from China. "We do sell our IGCC technology to China," Mariasundaram observed. GE, it may be mentioned, has supplied IGCC technology to the 618-mw Edwardsport Generating Station at Indiana, USA. Discussing GE's activities the renewable energy space, Mariasundaram explained that the thrust was on wind energy. GE has installed nearly 250 wind turbines in India. Significant R&D has been undertaken to develop turbines for low-wind regimes, especially relevant to India. GE is also working on a turbine of 1.7-mw rating that it expects to launch soon. When asked about GE's involvement in offshore wind turbines, Mariasundaram maintained that GE's current focus was on onshore turbines. "Offshore wind farms may experience higher wind velocities and more power generation, but they have their own set of challenges," he observed. GE is also actively involved in the solar (photovoltaic) power segment. Though GE does not actively produce photovoltaic modules—it has sold its technology to licensee FirstSolar of USA—it does provide electrical balance of plant equipment. eBOP involves aspects like inverters, substation automation, transformers, SCADA systems, etc. "eBOP is the key as far as optimization of the total plant is concerned," Mariasundaram noted.
I demand. Conversely, there are situations where there is high demand from the grid but low generation, in turn due to weak winds. GE is pursuing a technology where excess generation could be stored in a battery, which is synchronized with the wind turbine, and release it when there is demand from the grid. The battery technology, called "GE Durathon" is a proprietary energy-intensive technology that uses sodium. Such batteries have been deployed in a wind farm in Texas, bringing good results to the grid operator. GE also places great emphasis on analytics. An official concerned elaborated that analytics entails studying vast amounts of empirical information with a view to gaining ability to predict the future. Analytics is an important aspect of R&D and is applicable to all disciplines, the official said. Using analytics, GE has developed a "wake management" system for wind turbines. Explaining this concept, a GE researcher said that in a wind farm, each wind turbine tends to behave independently, thus
compromising on the overall performance of the farm. In the wake management system, each turbine can communicate to every other with an objective of achieving overall efficiency. A turbine can "sacrifice" some of its efficiency to ensure that the turbines function optimally as a team, the official said. Meanwhile, GE Energy Management showcased several electrification and automation solutions for various industries, through its divisions-industrial solutions, power conversion, digital energy and intelligent platforms. The transportation team traced the evolution of locomotives from the industrial age to the latest Tier-4
emission standard. Highlights at Techmela included the Indo-Java locomotive engineered by the JFWTC team and the suite of software solutions based on GE's Predix platform. The theme of this year's GE Techmela was "Past, Present & Future" of GE's technologies. A heritage zone offered a rare journey through the legacy of innovation build by GE over the past 122 years, beginning with the days of GE's founder Thomas A. Edison. While the GE Techmela was replete with innovative products and solutions, GE's ingenuity in weaving this diversity into an enrapturing event was by itself striking.

The Uttar Pradesh government has cleared the installation of several new power transformers but non-availability of land has become a hindrance. Some projects so affected include a 132/33kV substation with two 40 MVA transformer proposed at Indiranagar, a 220/33kV substation at Kanpur Road and a 132/33kV substation at Hanuman Setu. India has initiated the process to supply 100 mw of power from Tripura to Bangladesh, it is reported. Power will be supplied from ONGC’s Palatana gas-fired power plant in the south Tripura. The plan to supply power from Tripura to Bangladesh will be similar to the system between West Bengal's Baharampur and Bheramara in Bangladesh. India started supplying 250 mw of power to Bangladesh (via West Bengal) last year following an agreement reached between Bangladesh Power Development Board and India's NTPC Vidyut Vyapar Nigam Ltd (NVVN), a subsidiary of NTPC Ltd. Gamesa Corp Tecnologica SA, Spain’s large wind turbine maker, has won orders from five Indian wind farms to supply 172 mw of machines. The 86 turbines, to be made in India, will be delivered to projects in Madhya Pradesh, Gujarat, Karnataka, Rajasthan and Maharashtra states next year, the company said, without disclosing other details. So far this year, Gamesa has signed orders to supply 500 mw of wind turbines. The Uttar Pradesh government has sought a brand new transformer for its 500-mw Anpara unit two days after it failed to reignite. UP Rajya Vidyut Utpadan Nigam Ltd in early October had attempted to restart the machine two months after its transformer developed an irreparable snag. A transformer, which was borrowed from NTPC's Vidhyan Super Thermal Power Station, was put on functional mode. But the machine worked only for nine hours before going off the grid once again. Adani Power announced that it has demerged its transmission business from itself and its subsidiary, Adani Power Maharashtra, to form another wholly-owned subsidiary, Adani Transmission (India), in order to improve operational efficiency and focus on growth opportunities in the power transmission business. Tata Power plans to complete work on the 1,320-mw thermal power station in Vietnam by 2019, earlier than the originally-planned 2022. The company won the contract to develop the coal-fired Long Phu 2 power project in the southern Soc Trang province of Vietnam, on a Build-OwnTransfer (BOT) basis last year. An MoU for the project was signed between Tata Power and the government of Vietnam in November 2013.
