A short round-up of the India battery-storage headlines our desk tracked on 16 July 2026 — a supply-side day, with a new gigawatt-scale factory and two localisation partnerships taking the lead while the tender calls stay open. For the running list of live opportunities see our tender tracker; for how domestic manufacturing incentives fit in, our PLI ACC battery manufacturing guide.
Manufacturing & supply chain
The story of the day was on the factory floor, not the tender portal. AmpereHour Energy opened a 5 GWh BESS factory, while Havells tied up with Pixii and Amara Raja partnered Nuvation to localise high-voltage battery-management systems — three moves that push more of the value chain onshore. Pace Digitek’s earlier 1.25 GWh first-year milestone stayed in view:

- Havells partners with Pixii on battery storage push in India — ESS News
- Havells partners with Pixii on battery storage push in India — pv magazine India
- Amara Raja partners with Nuvation Energy to localize high-voltage battery management system technology in India — pv magazine India
- India’s Pace Digitek manufactures more than 1.25 GWh of BESS capacity in first year — ESS News
More domestic cell-to-pack and BMS capacity eases the local-content and lead-time pressures that shape how the standalone-BESS tenders below get bid.
Central / PSU tenders & PPAs
The big central deal — Serentica Renewables’ 600 MW / 2,400 MWh solar-plus-storage PPA with SECI for assured peak renewable power — stayed the anchor of the pipeline, alongside NTPC REL’s still-open contractor search for a 300 MW / 1,200 MWh project:
- Serentica Renewables signs PPA with SECI for 600 MW/2,400 MWh assured peak renewable power project — pv magazine India
- Serentica Renewables signs PPA for 600 MW/2,400 MWh solar-plus-storage project in India — ESS News
- NTPC REL seeks contractor for 300 MW/1,200 MWh storage project in India — ESS News

State tenders
Maharashtra’s twin calls remained the state-level focus — its 4 GWh standalone battery bid plus a smaller floating-solar-plus-storage tender:
- Maharashtra Invites Bids for 4 GWh Battery Energy Storage Projects — Mercom India
- Maharashtra Tenders 59 MW Floating Solar Plus 59 MWh Battery Storage Project — Mercom India
We walk through the larger call in our Maharashtra 4 GWh BESS tender guide.
Market outlook: C&I storage
On the demand side, two threads ran together: an analysis of why India’s commercial and industrial (C&I) buyers have been slow to adopt storage, set against forecasts that C&I deployments will still exceed 31 GWh by 2032:
- Why India’s C&I sector is slow to embrace battery storage — ESS News
- India’s C&I energy storage deployments set to exceed 31 GWh by 2032 — ESS News
- C&I energy storage deployments in India to exceed 31 GWh by 2032 — pv magazine India
For a C&I buyer the takeaway is simpler than the gigawatt-hours suggest: storage increasingly pays back on its own economics — Time-of-Day arbitrage and demand-charge savings — rather than on subsidy, a path that lines up with India’s broader 2032 storage targets.
