Hybrid
A gas-and-energy PSU procuring generation with co-located storage — the battery firms solar output and shifts a portion of it into the evening peak.
Mercom India ↗What it means
This is a generation-plus-storage hybrid, not standalone BESS: 600 MW of solar with 550 MWh of batteries to firm output and push part of the day’s generation past sunset. Notably it comes from GAIL — a gas-and-energy PSU diversifying into renewables — which shows storage procurement broadening beyond the transmission and generation utilities. It is a larger cousin of Maharashtra’s 59 MW floating-solar-plus-storage tender and follows the pattern behind our solar-plus-storage solutions.
As of this briefing the tender is open at the bidding stage — bidders should confirm current deadlines and terms on GAIL’s procurement portal. For how central storage tenders are structured, see our SECI standalone storage tenders explainer.
