What it means
FDRE (firm and dispatchable renewable energy) tenders bundle solar, wind and storage into a single round-the-clock-style contract — and they are now a primary driver of India’s BESS demand. At 4,800 MWh of required storage, FDRE-IX alone rivals a full year of past deployments, and its co-located design leans on ISTS waivers and central support to stay competitive.
As of this briefing the tender is open for bids and has not been awarded — we will record the winning developers here once SECI concludes the reverse auction.
