SECI Floats Tender for 1,200 MW/4,800 MWh FDRE Supply

The Solar Energy Corporation of India (SECI) has invited bids for 1,200 MW of assured peak power supply, equivalent to 4,800 MWh, from interstate transmission system (ISTS)-connected renewable energy projects under its FDRE-X tender.

The tender seeks Firm and Dispatchable Renewable Energy (FDRE) through tariff-based competitive bidding, with energy storage systems (ESS) mandatory.

The projects will be developed on a Build-Own-Operate (BOO) basis, with the selected developers entering into 25-year power purchase agreements (PPAs).

The minimum bid capacity is 50 MW, while the maximum capacity that can be offered by a parent company, affiliate, ultimate parent or group company is 600 MW.

The ESS can be owned by the developer or procured from a third party, while its technology can be changed during the PPA period. Only electricity charged into the storage system from renewable energy sources will qualify as renewable energy.

Under the tender, the buying entity will specify four peak hours for power delivery. The peak period may begin during non-solar evening hours and extend into the non-solar morning hours of the following day, subject to the specified conditions.

Developers must supply 4,000 kWh per MW of contracted capacity during the designated peak hours. Up to 5 percent of annual renewable energy may be sourced through green market mechanisms or bilateral arrangements outside the PPA.

A shortfall against the mandated supply will attract a penalty of 1.5 times the PPA tariff, subject to the specified limit of up to 400 MWh per 100 MW of contracted capacity.

SECI will conduct the bidding online, followed by an e-Reverse Auction. The RfS document has been priced at INR 59,000.

The pre-bid meeting is scheduled for October 14, while online bid submission closes on October 29. Offline bid documents must be submitted by November 2, with bids scheduled to be opened on November 3, 2026. The tariff will be discovered through competitive bidding and the e-Reverse Auction
