NTPC Green Energy Limited (NGEL), a wholly owned subsidiary of NTPC Limited has invited bids for the development of an 800 MW / 3200 MWh Battery Energy Storage System (BESS) at the NTPC REL Khavda Park in Gujarat, marking another major step in strengthening India’s large-scale renewable energy and storage infrastructure.
Issued under a domestic competitive bidding framework, the tender seeks eligible bidders for the Engineering, Procurement and Construction (EPC) package covering the complete development of the grid-connected BESS facility. The bidding process will follow a single-stage, two-envelope system comprising techno-commercial and price bids, followed by a reverse auction.
According to the tender document, the project will be developed at NTPC REL Khavda, Gujarat, with the full 800 MW/3200 MWh storage capacity integrated with solar infrastructure and the grid network. The scope includes design, engineering, supply, transportation, installation, testing, commissioning and integration of the BESS system on a turnkey basis.
The tender places significant emphasis on long-term operational performance. NTPC Green Energy has specified a 25-year design life for the BESS system, while the batteries offered must support a minimum of 10,000 operational cycles. The selected bidder will also be responsible for comprehensive Operations and Maintenance (O&M) and associated warranties for 15 years.
Performance benchmarks outlined in the tender include minimum 92% dispatchable capacity over 15 years, beginning with full rated capacity at commissioning and maintaining 95% during the first year. In addition, the project must ensure minimum 80% round-trip efficiency and 98% annual availability, reflecting the growing focus on reliability and performance in grid-scale energy storage deployments.
The BESS project is expected to play an important role in supporting renewable integration and grid stability at the Khavda renewable energy complex, one of India’s key clean energy development hubs. Large-scale storage systems such as this are increasingly being deployed to address intermittency challenges associated with solar generation and to enable more flexible power dispatch.
The tender, identified as IFB No. NRE-CS-5845-EPC-BESS, was issued on May 19, 2026, with detailed bidding documents available through NTPC’s tender platforms.
