A round-up of the India storage headlines our desk tracked to 13 August 2026 — and after a quiet weekend, an unusually dense run. Two hard capacity numbers landed within a day of each other, a national round-the-clock auction named its winners, and a battery plant opened rather than merely being announced. Each substantive story below has its own datasheet briefing. For the running list of live opportunities see our tender tracker.
Awards and price discovery
The week’s two most useful numbers both came with megawatt-hours attached:
- GUVNL discovers INR 2.32 lakh/MW/month tariff in 450 MW/900 MWh BESS tender — pv magazine India · read our brief
- NTPC Green Energy wins 200 MW/800 MWh battery storage project in West Bengal — pv magazine India · read our brief
- SECI announces winners of 1 GW round-the-clock renewables tender — ESS News · read our brief
- Juniper Green Energy wins 230 MW in SECI’s 1 GW FDRE RTC tender — pv magazine India
Read the two capacity awards together and you get the range of shapes Indian buyers are procuring right now. GUVNL’s 900 MWh behind 450 MW is a two-hour peaking battery; NTPC Green’s 800 MWh behind 200 MW is a four-hour long-duration block — twice the storage per megawatt of connection, for a different job. That split is the single most consequential design choice in a storage tender, and we unpack it in 2-hour vs 4-hour BESS explained.
The GUVNL price is also worth filing carefully. At ₹2.32 lakh/MW/month it is a capacity charge, the structure used for standalone BESS, and it is not comparable with the ₹5.25/kWh blended energy tariff SECI discovered in its round-the-clock round last week — that one has now moved on to naming winners.
New tenders and calls
- Maharashtra Invites EOIs for 170 MW Floating Solar Project with Battery Storage — Mercom India · read our brief
- Chhattisgarh Invites Bids for 1,000 Off-Grid Solar Systems with Storage — Mercom India
Maharashtra’s is an expression of interest rather than a tender, so the battery is not yet sized in public — the stage at which specifications are still movable. Chhattisgarh’s thousand off-grid systems sit at the opposite end of the scale from the gigawatt-hour headlines: small distributed batteries, procured in volume, doing the job the grid does not reach. Both fit the state frameworks in our India BESS policy overview.
Manufacturing and supply chain
- Octillion Opens Third Battery Plant in India With 3 GWh Annual Capacity — Mercom India · read our brief
- Waaree Transpower secures INR 160 crore order for BESS medium-voltage skids — pv magazine India
- MiniMines Cleantech secures Indian patent for hybrid hydrometallurgy battery recycling technology — pv magazine India
Octillion’s is the one to weight: a plant that has opened, not one that has been announced. The Waaree order is a reminder that a BESS is not only cells — medium-voltage skids, transformers and switchgear are a real share of the installed cost, and domestic supply of that balance-of-plant is tightening alongside the packs. MiniMines’ recycling patent belongs to the other end of the asset life, covered in our second-life batteries and recycling guide.
Grid policy
Requiring renewables to provide primary frequency response is, in practice, a requirement for storage or for headroom deliberately held back from generation — batteries are the cheapest way to hold a fast reserve. It is the same mechanism behind the market we describe in ancillary services and frequency regulation, now appearing in a Bihar drafting document.
Tender terms and deadlines change by notification — always verify the current bid documents on the issuing organisation’s portal before acting.
