NTPC Green Energy has issued a large-scale EPC tender for an 800 MW/3200 MWh Battery Energy Storage System at Khavda Park, reinforcing India’s growing focus on grid-scale energy storage and renewable integration.
NTPC Green Energy Limited (NGEL) has issued an EPC tender for the development of an 800 MW/3200 MWh Battery Energy Storage System (BESS) at the NTPC REL Khavda Park as India continues to scale up its energy storage infrastructure.
The project will be financed through the company’s own resources and borrowings, with bids invited until 5 June 2026.
The turnkey EPC package includes design, engineering, supply, transportation, installation, testing, commissioning, and grid integration of the BESS infrastructure.
According to the tender conditions, bidders must guarantee a minimum dispatchable capacity of 92% at the Point of Interconnection (POI) throughout the 15-year operational period. The system is expected to begin operations with 100% rated dispatchable capacity at the Commercial Operation Date (CoD) and maintain 95% during the first operational year.
Any augmentation required to maintain the guaranteed performance levels will remain within the bidder’s scope. The tender also specifies that the BESS system, including batteries, should have a design life of 25 years with batteries rated for at least 10,000 operating cycles under daily single-cycle operations.
The scope additionally covers integration with balance-of-system infrastructure, including associated solar plants and grid connectivity.
NTPC Green has also mandated comprehensive operation and maintenance (O&M) services, including warranties and service-level agreements, for a period of 15 years. The project must maintain a minimum monthly Round Trip Efficiency (RTE) of 80%, including auxiliary consumption, along with annual availability of 98%.
The latest tender follows NTPC’s earlier award of a 50 MW/100 MWh BESS EPC project to SolarWorld Energy Solutions Limited for deployment at the Feroze Gandhi Unchahar Thermal Power Station in Uttar Pradesh. The project, valued at approximately Rs 108 crore, is being developed at the Unchahar site.
The tender reflects the growing role of battery energy storage systems in supporting India’s renewable energy integration, grid stability, and long-term energy transition goals.
