A short round-up of the India battery-storage headlines our desk tracked on 10 July 2026 — a busier day than the last, with a large signed PPA, a new state tender and a manufacturing milestone joining the calls still open. For the running list of live opportunities see our tender tracker; for how these fit the wider rulebook, our state-wise policy guide.
State tenders
Maharashtra widened its already-busy procurement with a fresh floating-solar-plus-storage call, sitting alongside its still-open 4 GWh battery bid:
- Maharashtra Tenders 59 MW Floating Solar Plus 59 MWh Battery Storage Project — Mercom India
- Maharashtra Invites Bids for 4 GWh Battery Energy Storage Projects — Mercom India
The 59 MW / 59 MWh call is a one-hour system paired with generation — a different profile from the standalone gigawatt-hour bids, but the same peak-management logic. We walk through the state’s larger call in our Maharashtra 4 GWh BESS tender guide.
Central / PSU tenders & PPAs
The headline of the day was Serentica Renewables signing a 600 MW / 2,400 MWh solar-plus-storage PPA with SECI for assured peak renewable power — a four-hour system and a clear signal of where central offtake is heading. NTPC REL’s contractor search for a 300 MW / 1,200 MWh project stayed open in the same window:
- 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
The NTPC REL call fits the standalone-BESS mould that dominates PSU procurement; we unpack its earlier 1,200 MWh calls in our NTPC REL 1,200 MWh tender briefing.
Manufacturing & supply
A supply-side milestone underlined that domestic cell-to-pack capacity is scaling alongside the demand pipeline:
More domestic manufacturing eases the local-content and lead-time pressures that shape how these tenders get bid.
Market outlook: C&I storage
Two outlets continued to carry the forecast that India’s commercial and industrial (C&I) energy-storage deployments will exceed 31 GWh by 2032 — the behind-the-meter demand signal sitting under most of the tender activity above:
- 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
That path lines up with India’s broader 2032 storage targets. 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.
