RAJASTHAN ELECTRICITY REGULATORY COMMISSION, JAIPUR In the matter of determination of generic tariff for sale of electricity from Wind Power Plants getting commissioned during FY 2015-16 in the State to Distribution Licensee. Coram: 1. Shri Vishvanath Hiremath, Chairman 2. Shri Vinod Pandya, Member 3. Shri Raghuvendra Singh, Member Date of Order: 29.05.2015 Order 1. The Commission has notified the RERC (Terms and Conditions for Determination of Tariff for Renewable Energy Sources - Wind and Solar Energy) Regulations, 2014 on 24.02.2014 (hereinafter called as the RERC RE Tariff Regulations, 2014). As per regulation 7(1) of the RERC RE Tariff Regulations, 2014, Commission may determine generic tariff on Suo-Motu basis at the beginning of each year of the control period for Wind Power Plants for which principles and norms have been specified under these Regulations. 2. Commission, based on the benchmark capital cost for wind power plants for FY 2014-15, and performance parameters contained in the RERC RE Tariff Regulations, 2014 had prepared the draft order to determine the generic tariff for the Wind Power Plants getting commissioned during FY 2015-16 and the same was issued for inviting comments/suggestions from the stakeholders The last date for submission of comments/suggestions by the stakeholders/public was 20.04.2015. WIND 2015-16 Page 1 of 16 3. Public notices were published in the following newspapers on the dates mentioned against each inviting comments/suggestions from the stakeholders on the draft order: Rajasthan Patrika : 21.03.2015 Rashtradoot : 21.03.2015 The Times of India : 22.03.2015 Public notices along with the draft order were also placed on the Commission’s website. 4. The Stakeholders who offered their suggestions/comments are mentioned at Annexure-I. 5. Commission has considered the comments/suggestions received from the stakeholders. The present regulatory exercise is limited to determination of generic tariff based on the parameters contained in RERC RE Tariff Regulations, 2014. The comments/suggestions of the stakeholders received on parameters such as capital cost, O&M Expenses and its escalation, interest on long term loan and working capital, working capital requirement (receivables of debtors), CUF and deration are already incorporated in the RERC RE Tariff Regulations, 2014 and this order has to follow the provisions of Regulations in respect of above mentioned parameters. 6. Commission, through this order, is determining the tariff for Wind Power Plants on Suo-Motu basis based on the parameters specified in the Regulations and duly taking note of the suggestions/comments made by stakeholders on the draft order circulated. 7. The issues raised by the stakeholders in their comments/suggestions have been broadly grouped and summarized as under: (1) Accelerated Depreciation benefit; (2) Surcharge on MAT/Income Tax Rate; (3) Discount Rate; WIND 2015-16 Page 2 of 16 8. (4) Applicability of tariff ; and (5) Competitive bidding in wind sector. The above issues and Commission’s analysis/decision thereon have been dealt in the following paras: (1) Accelerated Depreciation Benefit 9. In the draft order, for determining higher depreciation benefit, the depreciation rate of 15% of the written down value (WDV) as per the Income Tax Act, 1961 has been compared with the depreciation rate specified under the RERC RE Tariff Regulations, 2014 i.e. 5.83% of the capital cost per annum on Straight Line Method (SLM) basis for 12 years and the remaining depreciable value spread over the remaining useful life of the project from the 13th Year onwards. 10. It has been requested by the stakeholders that Government of India vide its Notification No.43/2014/F.No.152/1/2013-TPL S.O. 2399(E) dated 16.09.2014 has reinstated the benefit of Accelerated depreciation of 80% for Wind Power Plants installed on or after 1.04.2014. Accordingly, the generic tariff may be worked out. Commission’s views/decision 11. Commission has considered the GoI Notification No.43/2014/F.No.152/1/2013-TPL S.O. 2399(E) dated 16.09.2014. In consideration of this, Commission decides that for the purpose of assessing levellised benefit of accelerated depreciation, the depreciation rate of 80% as per the said Notification of GoI be considered instead of 15% considered in the draft order. Accordingly, the tariff computations have been revised. WIND 2015-16 Page 3 of 16 (2) Surcharge on MAT/Income Tax Rate 12. Commission in the draft order for the purpose of grossing up the base rate of return on equity provided under regulation 15(3) of the RERC RE Tariff Regulations, 2014, has considered the MAT rate of 20.39% (= 18.50% MAT rate+7% surcharge + 3% cess) for first year and a MAT rate of 19.06% (= 18.5% MAT rate + 3% cess) for remaining nine years of the first ten years. For remaining fifteen years of plant life (also equal to useful life), the normal tax rate of 30.90% (= 30% tax rate + 3% cess) has been applied for grossing up of the base rate of Return on Equity. Similarly, for determination of levellised benefit of higher depreciation also, Commission has considered tax rate of 33.06% (=30% tax rate+7% surcharge+3% cess) for the first year and 30.90% (= 30% tax rate+ 3% cess) for subsequent years. 13. Stakeholders have also requested to consider rate of surcharge of 10% in place of 7% in arriving at the rates of Minimum Alternate Tax (MAT) and Corporate Tax. Another suggestion that surcharge at the rate of 10% and education cess at the rate of 3% may be considered for applying MAT and Income tax for entire project life of Wind Power Project has also been received. Commission’s views/decision 14. As regards considering higher rate of 10% for surcharge as against 7%, Commission observes that as per the Union Budget 2015 declaration, the rate of the surcharge has been increased to 7% from the existing 5% in case net taxable income is more than ` 1Crore but less than ` 10 Crores for the domestic companies for FY 2015-16. Further, the rate of surcharge has been increased to 12% from the existing 10% in case net taxable income is more than ` 10 Crores for domestic companies. The capacity of most of the wind power plants supplying power to the State Discoms is small where total net annual income of such plants relevant for levellised tariff would be less than ` 10 Crores. Therefore, WIND 2015-16 Page 4 of 16 these companies would not be subject to surcharge rate of 12%. Therefore, the suggestion for change is not accepted and it is decided to continue to take the surcharge at the rate of 7% in the computation of generic tariff. 15. The suggestion of considering the rate of surcharge of 10% and education cess at the rate of 3% for applying MAT and Income tax for entire project life were received earlier also and the same has been dealt in detail in the Tariff Order dated 16.07.2014. In the said order Commission has relied upon the Hon’ble APTEL judgement in the matter of M/s Enercon (India) Limited and Indian Wind Power Association (Rajasthan State Council) vs. Rajasthan Electricity Regulatory Commission, Jaipur and Ors. reported in 2011 ELR (APTEL) 0987 wherein APTEL had upheld the methodology of not considering surcharge on MAT for second to tenth year and on corporate tax for eleventh to twentieth year. Therefore, Commission considers it appropriate that no change is required as far as levy of surcharge is concerned. Considering above, Commission in the present order has also determined the levellised tariff based on the methodology hitherto followed. (3) 16. Discounting Rate: Commission in the draft order has computed discount factor considering the normative debt equity ratio and weighted average of the post tax rates for interest and equity components. In the computation, for loan component (i.e.70%) of the capital cost, the post tax interest rate of 13% multiplied by factor (1-Tax rate) has been considered. For equity component (i.e.30%), post tax rate of return of 16% has been considered. In this manner, the discount factor had been computed as 10.89% [=70% * 13% * (1-33.06%) + 30% *16%] and considered in computations of the levellised tariff. 17. A suggestion has been made that in the computation of discounting factor, the MAT rate may be considered for the first ten years and WIND 2015-16 Page 5 of 16 corporate tax rate may be considered for eleventh to twenty fifth year instead of considering corporate tax rate for the entire duration of twenty five years. Another suggestion states that Commission has considered income tax rate of 30.90% for grossing up the RoE in computation of levellised tariff instead of income tax rate of 33.06% considered in the draft order. The income tax rate of 30.90% used in tariff computations may be considered for the purpose of computation of Discount factor also. Commission’s views/decision 18. In the financial terms, levellised tariff is the uniform tariff (per kWh) of a cash stream that has the same present value as the total cost of generation of a generating plant over its life. The discount rate is the single rate used to convert the future costs to present value in a common year. In view of this, in computing the discount rate, Commission had proposed income tax rate applicable for arriving at present value in the draft order. It is mentioned that in the draft order Commission had considered income tax rate of 33.06% for first year in the AD benefit computations, which is also the relevant year for arriving at the present value. In consideration of this, Commission has retained the income tax rate of 33.06% in computations of discounting factor also and no change is required on this account. 19. As regards the suggestion of considering MAT for ten years and Income tax rate from eleventh year in computation of discounting factor, it is clarified that suggested principle is applicable for the purpose of computing yearly cost of generation whereas the discounting factor, as explained earlier, is used to convert these costs to present value in a common year. Therefore, relevance and purpose of income tax rate in both the situations is different. Commission, therefore, does not accept the suggestion. WIND 2015-16 Page 6 of 16 Applicability of tariff: 20. Stakeholders requested for providing clarity as regards the applicability of tariff for two months of the current financial FY 2015-16 until the final tariff is announced. Commission’s views/decision 21. It is clarified that the tariff determined through this order shall be applicable from the beginning of the current financial year i.e. from 01.04.2015. Competitive bidding in wind sector: 22. One suggestion has been made that technology (design, efficiency) and scaling (larger rotor and hub height leading to higher CUFs) improvements have resulted in lowering of the levellised cost of Wind electricity in spite of increase in upfront capital costs. The indexing formula used by many SERCs is unable to capture all such factors relevant to the final price of electricity in view of inherent problems in determining the benchmark capital costs and CUF, the other assumptions for interest rates, RoE expectations, with variation in discount rate (used for levelising the tariff). The discount rate is dependent on interest rates and RoE, which vary from investor to investor as evident from equity and debt investments from outside India, (where RoE expectations are much lower and cost of capital is much cheaper). In view of the above, the wind sector needs to emphasize on cost reductions and better performance. Competitive Bidding, if designed and implemented well, can be effective way to procure the required wind power at the least cost and further incentivise cost reduction. National Electricity Policy (NEP), National Tariff Policy (NTP) and NAPCC also provide for future procurements of renewable power to be based on competitive bidding. Notwithstanding the delay in MNRE/MoP notifying the bidding WIND 2015-16 Page 7 of 16 guidelines for renewable power procurement by Discoms, Commission should take lead in initiating the Wind sector to move towards competitive bidding based procurement(as envisaged under the NEP,NTP and NAPCC). This is all important given the revised national target of 60 GW wind power by 2022 and weak financial health of Discoms. Commission’s views/decision 23. It is stated that RERC RE Tariff Regulations, 2014 contain the enabling provision for adopting tariff if such tariff has been determined through a process of competitive bidding in accordance with the guidelines issued by the Central Government, as envisaged under Section 63 of the Electricity Act, 2003. However, it is noticed that Guidelines for procurement of RE power through competitive bidding are yet to be notified by the Central Government under Section 63 of the Electricity Act, 2003. On notification only, these Guidelines would be legally enforceable. Further, the present regulatory exercise is limited to the determination of tariff under cost plus regime. Considering this, the suggestion/comment relating to adopting competitive bidding deserves to be rejected. Accordingly, the suggestion is rejected. The levellised generic tariff for Wind Power Plants getting commissioned during FY 2015-16. 24. The levellised generic tariff for Wind Power Plants getting commissioned during FY 2015-16 has been discussed below: Useful Life 25. The regulation 2(22) of the RERC RE Tariff Regulations, 2014 provides for a useful life of 25 years for Wind Power Plants and accordingly, for computation of generic tariff, a useful life of 25 years has been considered. WIND 2015-16 Page 8 of 16 Tariff Period 26. The RERC RE Tariff Regulations, 2014 at regulation 5 specify that the tariff determined for the Wind Power Plants getting commissioned during the control period, shall continue to be applicable for entire duration of the tariff period as stipulated in Regulation 6 of the Regulations, which is 25 years for Wind Power Plants. Tariff Structure, Tariff Design and Levellised Tariff 27. As per regulation 8 of the RERC RE Tariff Regulations, 2014, the tariff for Wind Power Plants shall be a single part tariff consisting of following fixed cost components: 28. (a) Operation and Maintenance (O&M) Expenses; (b) Depreciation; (c) Interest on long-term loans; (d) Interest on Working Capital; and (e) Return on Equity. As per regulation 9 of the RERC RE Tariff Regulations, 2014, the generic tariff for Wind Power Plants shall be determined on levellised basis for the tariff period and that for the purpose of levellised tariff determination, the discount factor have been considered as per RERC (Terms and Conditions for Determination of Tariff for Renewable Energy Sources-Wind and Solar Energy) (First Amendment) Regulations, 2015. The calculations for discount factor are available at Annexure-II, accordingly the discount factor considered is10.89%. Capital Cost 29. Commission at regulation 22(2) of the RERC RE Tariff Regulations, 2014 has specified a normative Capital cost of ` 565 Lakh/MW for Wind Power Plants for FY 2014-15. This capital cost is also inclusive of ` 25 Lakh/MW towards the cost of transmission system including pooling WIND 2015-16 Page 9 of 16 station upto the interconnection point, and this ` 25 Lakh/MW also includes ` 2 Lakh/MW for grid connectivity charges payable to Transmission licensee for the FY 2014-15. 30. In the draft order, in order to arrive at the capital cost for FY 2015-16, the capital cost indexation formula specified at regulation 23 of the RERC RE Tariff Regulations, 2014 has been applied on the total capital cost of ` 565 Lakh/MW specified for the base year FY 2014-15. As per regulation 36 of the said Regulations, the connectivity charges of ` 2 Lakh/MW are fixed. Therefore, the capital cost indexation factor is to be applied on capital cost reduced to the extent of connectivity charges of ` 2 Lakh/MW, i.e., on ` 563 Lakh/MW (=` 565 Lakh/MW- ` 2 Lakh/MW. Accordingly, for arriving at the capital cost for FY 2015-16, connectivity charges are to be added back the to this escalated cost. 31. In accordance to the above, the normative capital cost for FY 2015-16 works out to be ` 579.00 Lakh/MW, which is inclusive of the cost of transmission system including pooling station upto the interconnection point and also includes ` 2.00 Lakh/MW for grid connectivity charges payable to Transmission licensee for the FY 2015-16. The detailed calculations of the indexation mechanism and determination of capital cost for FY 2015-16 thereof, are available at Annexure-III. Debt-Equity Ratio 32. The Debt-Equity ratio of 70:30 as envisaged at regulation 15 of the RERC RE Tariff Regulations, 2014 has been taken for working out the debt and equity components of normative capital cost for determination of levellised generic tariff. Capacity Utilisation Factor (CUF) & de-ration in CUF 33. Regulation 24(1) of the RERC RE Tariff Regulations, 2014 provides for CUF of 21% for Jaisalmer, Jodhpur and Barmer districts and 20% for other districts. Further, regulation 24(2) of the said Regulations also WIND 2015-16 Page 10 of 16 stipulates a de-ration of 1.25% from 6th, 10th, 14th & 18th year in the above CUFs. Accordingly, CUFs along with de-ration have been taken. Operation & Maintenance (O&M) Expenses 34. Normative O&M expenses have been taken as ` 7.87 Lakh/MW for Wind Power Plants for FY 2014-15 in accordance with regulation 25(1) of the RERC RE Tariff Regulations, 2014 and same have been escalated at the rate of 5.85% for arriving at O&M expenses for FY 2015-16 as ` 8.33 Lakh/MW. Further, the O&M Expenses have been escalated @ 5.85% over the tariff period for computation of the levellised tariff, for the plants to be commissioned in FY 2015-16 as per the regulation 25(2) of the RERC RE Tariff Regulations, 2014. Depreciation 35. In accordance with regulation 14 of the RERC RE Tariff Regulations, 2014, the rate of the depreciation for the first 12 years has been considered as 5.83% of the capital cost per annum and from 13th year onwards, the remaining depreciable value has been spread over the balance useful life of the wind power plant and transmission system. Interest rate on long term loan 36. In accordance with sub-regulation (1) of regulation 13 of the RERC RE Tariff Regulations, 2014, the loan tenure of 12 years has been considered for the purpose of determination of generic tariff for Wind Power Plants. Sub-regulation (2) of regulation 13 of the said Regulations further provides for the interest rate on long term loans as 300 basis points higher than the average State Bank of India (SBI) base rate prevalent during first six months of the year previous to the relevant year. 37. Accordingly, the average SBI base rate obtained from official website of SBI, prevalent during first six months of the year FY 2014-15 has been WIND 2015-16 Page 11 of 16 considered for computation of applicable interest rate, as shown in the table below: Table-1: Average SBI base rate during first six months of FY 2014-15 Period from Period to 1.04.2014 30.09.2014 Average SBI Base rate for FY 2014-15 38. Base rate 10% 10% No. of days 183 183 In terms of the above, the interest rate of 13.00% (=10.00%+3.00%) has been used for computation of interest on long term loan in generic tariff computations, treating loan as 70% of the capital cost. Interest on working capital requirement 39. For the purpose of working capital requirement, the composition of working capital has been taken as per regulation 16(1) of the RERC RE Tariff Regulations, 2014. 40. In accordance with regulation 16(2) of RERC RE Tariff Regulations 2014, the interest rate on working capital for Wind Power Plants has been taken as 250 basis points higher than the average of SBI Base rate prevalent during first six months of FY 14-15, which works out to be 12.50% (=10.00%+2.50%). Accordingly, a rate of 12.50% has been taken as interest rate on working capital requirements. Return on Equity 41. Regulation 15(2) of the RERC RE Tariff Regulations, 2014 provides for 16% Return on Equity on equity base of 30% determined in accordance with regulation 12 of the said Regulations. As per regulation 15(3) of the RERC RE Tariff regulations 2014, Return on Equity has been computed by grossing up the base rate of 16% with tax rate equivalent to Minimum Alternate Tax (MAT) for first 10 years from COD and normal tax rate for remaining years of the project life. In line with the practice followed during the previous control period, the MAT rate of 20.39% (= 18.5% MAT rate + 7% surcharge + 3% education cess) has been WIND 2015-16 Page 12 of 16 considered for first year and a MAT rate of 19.06% ( = 18.5% MAT rate + 3% education cess) has been considered for remaining 9 years of the first 10 years. For remaining 15 years of plant life (also equal to useful life), the normal tax rate of 30.90% (= 30% tax rate + 3% education cess) has been applied for grossing up of the base rate of Return on Equity. Subsidy or Incentive by the Central Government, including Accelerated Depreciation 42. As per the regulation 21 of the RERC RE Tariff Regulations, 2014, the Commission shall take into consideration any incentive or subsidy or benefit available from Central or State Government, including accelerated or higher depreciation benefit, if availed by the generating company, for the renewable energy power plants while determining the tariff under these Regulations. Further, the Generation Based Incentive/Tariff Subsidy, if allowed by the Central/ State Govt., would be governed by the terms and conditions of such scheme. 43. For the purpose of determining the accelerated depreciation (AD) benefit, as dealt earlier, the depreciation as per the Regulations (5.83% for 12 years and 2.50% for the remaining useful life)( as also allowed under the Companies Act,2013) has been compared with depreciation rate as per Income Tax Act, i.e., 80% of the written down value vide GoI Notification No.43/2014/F.No.152/1/2013-TPL S.O. 239(E) dated 16.09.2014. However, in addition to this, an additional depreciation of 20% has been allowed to the Wind Power Projects during the first year in an amendment in the Finance Act, 2012. In this computation, the capitalization has been considered during the second half of the fiscal year, as provided at regulation 21 of the RERC RE Tariff Regulations, 2014. The energy available in the second half of the year has been taken as 30% of annual generation as the energy availability from wind power plant in the second half of the year is much lower than the first half, i.e., during April to September 70% and WIND 2015-16 Page 13 of 16 30% in the second half of the year. The levellised generic tariff has been worked out considering both the situations, viz., if accelerated depreciation benefit is availed and if not availed. Levellised Tariff 44. The levellised tariff has been determined for the useful life of the Wind Power Plants i.e. for 25 years. Therefore, PPA should be for 25 years. 45. In light of the above position, the levellised generic tariff for Wind Power Plants getting commissioned for FY 2015-16 has been determined as under: Table-2: Generic Tariff for Wind Power Plants getting commissioned during FY 15-16 S. No Particulars . 1 2 1 Wind Power Plants located in Jaisalmer, Jodhpur & Barmer districts 2 Wind Power Plants located in districts other than Jaisalmer, Jodhpur & Barmer districts. 46. Tariff (`/kWh) if AD benefit is not availed 3 5.74 Tariff (`/kWh) if AD benefit is availed 4 5.14 6.02 5.39 For Wind Power Plant claiming the higher tariff worked out as above for projects not availing accelerated depreciation benefit, Commission considers it appropriate to lay down modalities as under: (1) The PPA should include an undertaking of the Wind Power generator that accelerated depreciation benefit would not be availed for the generating plant/unit. (2) The first bill raised by the Wind Power generator shall be accompanied by an undertaking that accelerated depreciation benefit shall not be claimed. Based on this, the applicable tariff would be allowed. WIND 2015-16 Page 14 of 16 (3) The claims of energy charges as per applicable tariff may be entertained based on the said undertaking upto the due date of filing of Income Tax Return of the relevant financial year. This would mean 30th September, 2015 for payment for the financial year 14-15 and for the first six months (upto 30th September) of financial year 15-16 and so on. (4) After filing of Income Tax Return a certificate from a Chartered Accountant (CA) that accelerated depreciation has not been claimed would have to be submitted or in the alternative a copy of Income Tax Return filed with Income Tax Department wherein it is shown that accelerated depreciation has not been claimed along with verification of Tax Consultant may be furnished. (5) As Income Tax Return is required to be filed in the next year, the payment of amount corresponding to non-availment of accelerated depreciation in respect of energy supplied in the month of October onwards of the financial year following the financial year of commissioning of the plant would be made only after the said certificate/copy of Income Tax Return is furnished. (6) For the energy supplied in the months of October onwards, the methodology as given in sub-paras (4) & (5) above be followed. 47. Commission also considers it appropriate that undertaking of the Wind Power generator in PPA stating that benefit of accelerated depreciation would not be claimed should also include an undertaking that in case it is found that benefit of accelerated depreciation has been claimed, as per third proviso to regulation 21 of the RERC RE Tariff Regulations 2014, the distribution licensee shall be entitled to recover the amount wrongly claimed by the Wind Power generator along with penal charges @ 1.50% per month calculated on daily basis. 48. Similarly, annual undertaking would need to be furnished if CDM benefit is not availed. However, if CDM benefit is availed, it would have WIND 2015-16 Page 15 of 16 to be shared between the distribution licensee and generating company as envisaged in regulation 20 of the RE RERC Tariff Regulations 2014. 49. The metering arrangement shall be as per regulation 37 of the RERC RE Tariff Regulations, 2014. 50. Commission in exercise of its power conferred under Section 62 read with Section 64 of the Electricity Act,2003 and the RERC RE Tariff Regulations, 2014 determines the generic tariff of Wind Power Plants as detailed in Annexure-IV and Annexure-V. 51. The above Tariff is applicable for the Wind Power Plants commissioned on or after 1.04.2015 and till 31.03.2016. 52. Copy of this order may be sent to the State Government, Central Electricity Authority (CEA), Rajasthan Renewable Energy Corporation Ltd (RREC), Distribution Licensees and all stakeholders.
