A 750 MWh call from a coal PSU — storage procurement is spreading beyond the power utilities to India's large industrial buyers.

What it means

At 750 MWh this is a utility-scale system, though the headline does not state the battery’s power rating — so the discharge duration, and whether it is shaped for evening-peak cover or longer shifting, is not yet public. Our explainer on two-hour versus four-hour systems sets out how that one number changes the whole design.

What stands out is the buyer. Coal India is a miner, not a DISCOM, and a storage tender of this size from a central industrial PSU points to captive and mine-site load being firmed with batteries rather than only grid-side procurement — the same logic behind the standalone BESS projects we build, and consistent with the direction of Telangana’s storage policy.

As of this briefing the tender is open at the bidding stage — deadlines and the eventual award will be updated here as they are published.
