New Delhi: NHPC Limited has invited bids from developers to establish battery energy storage systems (BESS) and supply solar-plus-storage power from the 1,200 MW Jalaun Solar Park in Uttar Pradesh. The initiative aims to integrate large-scale battery storage with solar generation and improve the availability of renewable electricity during periods of demand.
The tender has been issued on behalf of Bundelkhand Saur Urja Limited (BSUL), a joint venture of NHPC and the Uttar Pradesh New and Renewable Energy Development Agency (UPNEDA).
According to the tender notice published on November 4, developers will be selected through tariff-based competitive bidding (TBCB), followed by an electronic reverse auction. The projects will be implemented under the Build, Own and Operate model.
NHPC has invited bids for two configurations, each involving an 800 MW battery storage system but differing in the solar capacity and storage duration.
Two Configurations Offered for 800 MW Battery Storage
The tender allows developers to participate in either or both configurations, subject to the eligibility and allocation conditions.

The proposed configurations are:
- Configuration I: Integration of 300 MW of solar capacity with an 800 MW battery energy storage system, offering 4,800 MWh of storage.
- Configuration II: Integration of 600 MW of solar capacity with an 800 MW battery energy storage system, offering 3,200 MWh of storage.
A bidder can secure a maximum of 50% of the total contracted capacity and can be allocated no more than two location blocks.
The selected developers will establish storage facilities alongside the solar infrastructure and schedule electricity supply across peak and non-peak demand periods.
Jalaun Solar Park to Supply 2,419 Million Units Annually
The 1,200 MW Jalaun Solar Park is being developed in Jalaun district across the Orai and Madhogarh tehsils.
Coal India Limited and NLC India Renewables Limited have been selected as solar power developers for the park, which has an annual contracted generation of approximately 2,419 million units (MU).
The BESS tender is intended to utilise this existing solar generation more effectively by combining it with battery storage. The arrangement is expected to improve the flexibility of renewable power supply and help meet the electricity requirements of procurers during different demand periods.
Under the proposed arrangement, the selected BESS developer will procure the solar generation from the park at tariffs ranging from ₹2.61 to ₹2.62 per kWh, as specified in the procurement framework.
Four Project Blocks and Transmission Arrangements
The project has been divided into four blocks located near three 33/400 kV pooling substations.
Electricity generated through the combined solar and storage arrangement will be delivered at the designated 765/400 kV inter-state transmission system (ISTS) substation identified by the Central Transmission Utility of India Limited (CTUIL).
The arrangement is designed to integrate solar generation and battery storage with the existing transmission network, enabling more flexible scheduling and dispatch of electricity.
Bid Submission Deadline and Selection Process
NHPC has invited bids through a single-stage, two-envelope procurement process, involving separate technical and financial submissions.
Important tender details include:
- Tendering authority: NHPC Limited, on behalf of BSUL.
- Tender publication date: November 4, 2026.
- Bid submission deadline: December 15, 2026.
- Technical bid opening: December 16, 2026.
- Selection method: Tariff-based competitive bidding followed by an electronic reverse auction.
- Project model: Build, Own and Operate (BOO).
Bidders are required to submit the prescribed Earnest Money Deposit (EMD) and bid processing fee. Successful applicants will also have to furnish separate Performance Bank Guarantees for each awarded project after receiving the Letter of Award and before signing the Power Purchase Agreement with BSUL.
The tender documents specify the financial and technical eligibility conditions, along with the applicable security requirements.
Strengthening Renewable Energy Storage in Uttar Pradesh
The Jalaun tender represents an effort to address one of the key challenges associated with large-scale solar power generation: its dependence on sunlight and the resulting variation in electricity availability.
By integrating battery storage with the solar park, the project is expected to make renewable electricity more flexible and accessible during periods when solar generation is low or demand is high.
The initiative also supports India’s broader renewable energy expansion by combining solar generation with energy storage infrastructure and strengthening the capacity to deliver scheduled, dispatchable power.
