In early August 2026, India saw two major steps in scaling up battery storage for renewable power. On 5 August, Serentica Renewables, backed by Vedanta, commissioned the first 200 MWh phase of a planned 1 GWh battery energy storage system in Bikaner, Rajasthan. The facility is designed to store excess solar and wind generation for round‑the‑clock supply to industrial users and is part of a 7 GWh storage pipeline slated for the next two years.

Two days later, on 7 August, the Maharashtra Electricity Regulatory Commission approved a 220 MW solar procurement combined with a 110 MW/440 MWh battery storage system for Mumbai’s Brihanmumbai Electric Supply and Transport (BEST). The deal, sourced from SECI under a 25‑year power sale agreement, fulfills BEST’s renewable purchase and energy‑storage obligations while stabilising electricity costs.

Together, these projects illustrate a rapid expansion of large‑scale battery storage and solar‑plus‑storage contracts across India, driven by corporate investment, regulatory support, and a push for firm‑dispatchable renewable electricity.
