In a recent order, Haryana Electricity Regulatory Commission (HERC) approved Haryana Power Purchase Center’s (HPPC) petition for approval of source as well as approval of the draft Power Supply Agreement (PSA) for procurement of 800 MW ISTS connected Wind Solar Hybrid Power under Tranche IV scheme of Solar Energy Corporation of India Limited (SECI) at a levelized tariff of Rs. 2.34/kWh for 700 MW and Rs. 2.35/kWh for 100 MW plus a trading margin of Rs. 0.07/kWh for a period of 25 years.
On Feb 2022, after receiving an offer of 1200MW wind solar hybrid solar power from SECI under tranche IV scheme, HPPC reviewed the offer and enquired to SECI about potential implication with respect to BCD, GST and ISTS losses. SECI mentioned that the hybrid power developers (HPD) have been selected through a transparent competitive bidding process for the proposed 1200MW capacity. Subsequently, SECI provided the details with respect to ISTS losses, impact of BCD, GST for the project. After analyzing SECI’s proposal and submission, HPPC pursued the same in the 62nd and 63rd meetings of the Steering Committee of Power Planning (SCPP). Pursuant to the decision of SCPP, HPPC gave its consent to procure 1200 MW of Wind Solar Hybrid Power at Rs. 2.34/kwh (levelized) including SECI’s Trade Margin. It was explicitly stated that the said tariff is inclusive of the impact of BCD imposed on solar modules/panels etc. and is eligible for ISTS waivers.
In response, SECI intimated to HPPC that it can only supply 800 MW power out of the total capacity of 1200 MW of that particular scheme since it had already consented to supply the rest of the power to other buyers. They also stated the applicable tariff including the trading margin under the PSA will be Rs. 2.41/kwh for 700 MW and Rs. 2.42/kwh for 100 MW out of total 800MW offered capacity. Subsequently, after receiving consent from SCPP for the revised 800MW capacity, HPPC submitted following prayers to the commission (HERC).
a. Grant source approval for procurement of 800 MW ISTS connected Wind Solar Hybrid Power under Tranche IV Scheme of Solar Energy Corporation of India Limited (SECI)at a levellized tariff of Rs. 2.34/kwh for 700 MW and Rs. 2.35/kwh for 100 MW plus trading margin of Rs. 0.07/kwh for a period of 25 years.
b. Grant approval to draft Power Supply Agreement (PSA).
Commission’s Analysis & Decision :
The Commission observes that HPPC has to meet state’s solar RPO targets fixed by the Commission, under Haryana Electricity Regulatory Commission (Terms and Conditions for determination of Tariff from Renewable Energy Sources, Renewable Purchase Obligation and Renewable Energy Certificate) Regulations, 2021 (HERC RE Regulations,2021).
|FY||RPO (%) (Other Non Solar)||RPO (%) (Large Hydro)||RPO (%) (Total Non Solar)||RPO (%) (Solar)|
Further commission observed that they had also approved 1088.1 MUs and 2901.8 MUs from Non-solar and Solar sources for compliance of RPO for the ARR FY 2021-22. The shortfall in fulfillment of RPO Solar targets by HPPC, for the FY 2021-22, is 1246 MUs. The cumulative shortfall in compliance of Solar and Non-Solar RPO, as on 31.03.2022 comes to be 2505 MUs and 605 MUs, respectively. In view of the above, it is evident that the proposed hybrid power purchase will further contribute in the state’s growing solar and non-solar RPO energy demand.
After analyzing above observations and other submission of HPPC, commission approved the draft Power Supply Agreement (PSA) and the source of power for procurement of 800 MW ISTS connected Wind Solar Hybrid Power under Tranche IV scheme of Solar Energy Corporation of India Limited (SECI) at a levelized tariff of Rs. 2.34/kWh for 700 MW and Rs. 2.35/kWh for 100 MW plus a trading margin of Rs.0.07/kWh for a period of 25 years.
