NHPC Invites Bids for 800 MW Battery Storage Project in India's Jalaun Solar Park

India's state-owned NHPC Limited has invited bids for an 800 MW battery energy storage system (BESS) linked to the 1.2 GW Jalaun Solar Park in Uttar Pradesh. The tender, issued on behalf of Bundelkhand Saur Urja Limited (BSUL), aims to integrate battery storage with solar generation to provide more reliable and dispatchable electricity.

The tender offers two configuration options:

Option 1: 300 MW of solar power dispatch during solar hours, supported by an 800 MW/4,800 MWh BESS for non-solar hours.

Option 2: 600 MW of solar power dispatch during solar hours, combined with an 800 MW/3,200 MWh BESS.

Developers can bid for either or both configurations, with final capacity allocation depending on power purchasers' requirements. The project will use a tariff-based competitive bidding process, with bids evaluated on the combined solar and storage tariff.

The battery systems will be developed across four sites near three substations surrounding the Jalaun Solar Park. No specific battery technology has been mandated, allowing developers flexibility in selecting their storage solutions.

Successful bidders must complete construction within 18 months of the Power Purchase Agreement (PPA) taking effect and secure all necessary project and transmission approvals.

NHPC issued the tender on November 4, 2026, with the bid submission deadline set for December 15, 2026.

The project represents another step in India's efforts to combine large-scale solar generation with battery storage, improving the flexibility and reliability of renewable power supply beyond daylight hours.
