Adyant, Serentica, AMPIN & ACME Bag SECI's Peak Supply FDRE Tender

Solar Energy Corporation of India Limited (SECI) has announced the winners of its tender for Inter-State Transmission System (ISTS)-connected firm and dispatchable renewable energy (FDRE) projects, with leading renewable developers Serentica Renewables, AMPIN Energy Transition, Adyant Emnersol Private Limited and ACME Solar securing capacities under the auction.

Serentica Renewables and ACME Solar emerged as the largest winners, bagging 600 MW of capacity each at a tariff of ₹6.28/kWh. AMPIN Energy Transition secured 199 MW at the same tariff of ₹6.28/kWh, while Adyant Emnersol Private Limited, a subsidiary of Datta Infra, won 100 MW at a slightly lower tariff of ₹6.27/kWh.

The results mark the conclusion of SECI’s competitive bidding process under the SECI-FDRE-VII tender, aimed at supplying firm renewable power during peak demand hours.

The closely clustered winning tariffs highlight the increasing maturity of India’s firm and dispatchable renewable energy market, particularly as developers combine renewable generation with energy storage to supply peak-hour electricity. The awarded capacity totals 899 MW, forming part of SECI’s broader push to scale dispatchable clean power.

Background: 1200 MW FDRE Tender

SECI had issued the tender for 1200 MW of ISTS-connected renewable energy projects with assured peak supply, designed to provide 4,800 MWh of electricity daily during high-demand hours. The initiative aligns with procurement guidelines from the Ministry of Power and the clean energy expansion goals of the Ministry of New and Renewable Energy.

Under the tender framework, SECI will act as an intermediary nodal agency, signing 25-year power purchase agreements (PPAs) with developers and supplying the power to buying entities across India. The minimum tender capacity was 50 MW and a maximum of 600 MW. As per the mandate of the tender, the developers have to supply power during peak hours for four hours. The peak hour is supposed to start from the non-solar hours (evening to morning). 

The projects must integrate Energy Storage Systems (ESS) and deliver 4,000 kWh per MW of contracted capacity during daily peak hours selected by buying entities, typically during non-solar evening and morning periods.

Developers are required to build the projects on a Build-Own-Operate (BOO) basis, including land acquisition, project installation, and transmission infrastructure up to the interconnection point. The tender also mandates that renewable generation and storage assets be co-located to ensure reliable peak power delivery.
