The Central Electricity Regulatory Commission (CERC) has adopted the tariff for 1,200 MW wind-solar hybrid power projects with assured peak power supply (Tranche VI) under the competitive bidding process conducted by the Solar Energy Corp. of India Ltd (SECI).
SECI had filed a petition before CERC under section 63 of Electricity Act for adoption of tariff discovered under the bid. The tender for 1,200 MW of wind-solar hybrid power projects with assured peak power supply was issued by SECI on November 2, 2022, under the tariff-based competitive bidding process in line with the guidelines of the Ministry of New and Renewable Energy. SECI received eight bids totalling 2,390 MW, of which seven bidders qualified for the e-reverse auction held on April 12, 2023. Following the competitive bidding process, SECI awarded Letter of Award (LOA) dated 20.04.2023 to four successful bidders at tariffs ranging from INR 4.64/kWh to INR 4.73/kWh as below:
SECI has signed agreements for 600 MW capacity out of 1200 MW capacity. The power sale agreements (PSAs) were signed with Assam Power Distribution Company Ltd (APDCL) for 100 MW and Chhattisgarh State Power Distribution Company Ltd (CSPDCL) for 500 MW while the remaining 600 MW capacity is yet to be signed.
CERC vide order dated 24.02.2025 approved the tariff for the 1,200 MW projects, stating that the bidding process was conducted in accordance with the competitive bidding guidelines issued by MNRE. CERC considered all parameters and approved the discovered tariff and the trading margin of INR 0.07/kWh, subject to SECI ensuring compliance with payment security mechanisms and other conditions.
The tariff adoption by CERC is a mandatory legal requirement under Electricity Act and Power Purchase Agreements and it provides regulatory certainty to the entire bidding process and ensures the sanctity of the discovered tariff, paving the way for the successful bidders to proceed with project execution and financial closure.
