India's BESS Tender Watch: Week of August 9–15, 2026

Battery energy storage kept its place at the center of India's power procurement calendar this week. Gujarat dominated the headlines with both a fresh gigawatt-scale tender and a completed auction, while West Bengal wrapped up a delayed storage bid and New Delhi reaffirmed its funding commitment to the sector. Here's everything that moved on the BESS tender front this week, who issued it, how big it is, where it sits, and who came out on top where results are in.

New Tenders Issued This Week

GUVNL floats 1,000 MW / 4,000 MWh standalone BESS (Phase-X) — Gujarat

Issuer: Gujarat Urja Vikas Nigam Limited (GUVNL) Size: 1,000 MW / 4,000 MWh (4-hour duration), standalone battery storage Location: Gujarat Details: Floated on August 13, 2026, this is GUVNL's tenth phase of BESS procurement and one of the largest single BESS tenders issued in India this year. Bids are due online by September 14, 2026. It follows directly on the heels of GUVNL's Phase-IX auction, which just concluded (see winners below), underscoring how aggressively Gujarat is scaling up grid-connected storage to firm up its growing renewable capacity.

JdVVNL's 150 MW / 600 MWh pilot decentralised BESS — Rajasthan

Issuer: Jodhpur Vidyut Vitran Nigam Limited (JdVVNL), Rajasthan Size: 150 MW / 600 MWh, structured as 150 individual units of 1 MW/4 MWh each, split into 12 packages Location: Multiple decentralised sites across Rajasthan's JdVVNL distribution area Details: Part of Rajasthan's push toward grid decentralisation, this tender uses a Build-Own-Operate (BOO) model for small-scale, pilot-based standalone BESS units rather than one large centralised plant. The bid deadline fell within this week, on August 12, 2026.

Policy Backdrop: ₹5,400 Crore VGF Push

Alongside the tender activity, the central government used the week to reaffirm the financial scaffolding behind all this bidding. The Ministry of Power's Viability Gap Funding (VGF) scheme is channeling ₹5,400 crore through the Power System Development Fund to support 30 GWh of BESS capacity nationwide, plus transmission-charge waivers and other grid-integration incentives. This is the funding pool most state utility tenders (including GUVNL's Phase-IX and Phase-X rounds) are drawing on to make storage tariffs viable — it's worth flagging because it's the throughline connecting nearly every state-level auction currently in the market.

Tender Results: Who Won What This Week

GUVNL Phase-IX: 450 MW / 900 MWh BESS — Gujarat

Issuer: Gujarat Urja Vikas Nigam Limited (GUVNL) Original tender size: 450 MW / 900 MWh (2-hour duration), VGF-supported under Phase-IX of the Power System Development Fund Location: Gujarat, across ten designated substations Result (announced August 12, 2026):

• NLC India Renewables won 275 MW/550 MWh at a discovered tariff of ₹2,31,989 per MW per month

• Sun Drops Energia Ltd. (a subsidiary of KPI Green Energy) won the remaining 175 MW/350 MWh at ₹2,31,990 per MW per month

The two tariffs are separated by just ₹1/MW/month — about as tight a margin as a competitive auction produces — signaling how compressed pricing has become in Gujarat's BESS market. This was originally floated in June 2026 and took roughly two months to reach financial close. Formal Letters of Award and definitive agreements are the next step before site mobilization begins.

WBSEDCL: 500 MW / 2,000 MWh BESS auction — West Bengal

Issuer: West Bengal State Electricity Distribution Company Limited (WBSEDCL) Original tender size: 500 MW / 2,000 MWh, tariff-based competitive bidding (TBCB), floated in February 2026 after an earlier 250 MW/1,000 MWh version of the tender was annulled Location: West Bengal, embedded within WBSEDCL's distribution network Result (announced August 10, 2026): NTPC Green Energy Limited secured 200 MW/800 MWh of the total capacity at a tariff of ₹4.35 lakh per MW per month. Under the build-own-operate structure, NTPC Green will make the storage available to WBSEDCL for on-demand single-cycle charging and discharging to cover morning and evening peak demand. The remaining capacity from the 500 MW tender has not yet been fully allocated as of this writing.

The Week in One Line

Gujarat is setting the pace — closing one gigawatt-scale storage auction and opening an even bigger one in the same week — while West Bengal and the central government's VGF program show that BESS procurement is now a routine, multi-state exercise rather than a one-off experiment.
