A round-up of the India storage headlines our desk tracked to 25 August 2026 — a dense stretch in which a national auction put a price on four-hour peak power, a transmission utility opened another battery tender, and a firmed project actually came online. Each substantive story below has its own datasheet briefing. For the running list of live opportunities see our tender tracker.
Auction results and price discovery
- SECI discovers INR 5.99/kWh tariff for 4-hour peak renewable power — pv magazine India · read our brief
- ACME Solar wins 300 MW in SECI’s 1.5 GW/6 GWh tender for 4-hour assured peak power — pv magazine India
The auction SECI closed at the start of the week now has a number against it: ₹5.99/kWh for four hours of assured peak renewable power, with ACME Solar taking 300 MW of the 1.5 GW on offer. Treat it as an energy tariff for delivered peak supply — it is not comparable with the capacity charges, quoted in ₹ per MW per month, that standalone battery tenders discover. Six gigawatt-hours behind 1,500 MW is a four-hour block, the long-duration end of the split we unpack in 2-hour vs 4-hour BESS explained.
New tenders and calls
- POWERGRID Invites Bids for 530 MWh Battery Storage Project in Haryana — Mercom India · read our brief
- Maharashtra Invites Bids for 2.25 GW Solar Projects Under MSKVY — Mercom India
- Uttar Pradesh Tenders 2.5 MW Rooftop Solar Projects with Battery Backup — Mercom India
- Uttar Pradesh Tenders 11 MW Rooftop Solar Projects — Mercom India
POWERGRID’s 530 MWh in Haryana is the one to file: a transmission company buying batteries as network infrastructure, after its 3 GWh West Bengal call and its 500 MW / 1,000 MWh standalone tender. Maharashtra’s 2.25 GW is solar without a stated battery, and the two Uttar Pradesh rooftop calls are small — but the 2.5 MW one specifies battery backup, which is how distributed storage typically enters a state programme: quietly, in the specification, before it appears in the headline. State frameworks are mapped in our India BESS policy overview.
Projects commissioned
- Tata Power Renewables Arm Commissions 190 MW FDRE Project in Rajasthan — Mercom India
- Tata Power Renewables commissions 190.5 MW FDRE project in Rajasthan — pv magazine India
Same project, two outlets, and worth more attention than a tender of the same size: firm and dispatchable renewable energy projects are the ones that carry storage, and this one is generating, not contracted. Commissioned FDRE capacity is the evidence that the FDRE tender framework is converting into built assets in Rajasthan.
Manufacturing and supply chain
- Fujiyama to Add 1 GWh Lithium Battery Production Capacity in Madhya Pradesh — Mercom India · read our brief
- India, Finland should deepen cooperation on critical battery materials, green hydrogen: Dr Antti Herlevi — pv magazine India
Fujiyama’s gigawatt-hour is an announcement rather than an opening, so weight it accordingly — but each domestic line matters commercially because of the domestic content requirements now written into Indian storage tenders. The India–Finland item is diplomatic rather than industrial, though critical materials are the upstream constraint behind every one of these plants.
