Discharge signature — long-duration, runs 4h of 8h at rated power
Unlike most PSU calls, this one states both power and energy — and the 4:1 ratio puts it squarely in long-duration territory.
Mercom India ↗What it means
The useful detail here is that the headline gives both numbers. Most Indian storage tenders are reported in megawatt-hours alone, which leaves the single most consequential specification — the power rating — open until the bid documents appear. At 80 MW and 320 MWh the ratio is fixed at four to one, and a four-hour battery is a different machine from a two-hour one: more cells per megawatt, a smaller power conversion system relative to the energy block, and a duty cycle shaped for shifting bulk energy across the evening rather than covering a short peak. Our explainer on two-hour versus four-hour systems sets out how that choice propagates through the whole design.
The buyer matters as much as the ratio. Coal India is a miner, and this is its second storage tender we have tracked after a 750 MWh call in Telangana — evidence that large industrial PSUs are now procuring batteries on their own account rather than waiting for DISCOM programmes. Odisha’s own framework for this kind of procurement is covered in our state storage policy note, and the configuration itself is the standalone BESS architecture we build to.
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.
