NTPC Green Floats 800 MW/3200 MWh Khavda BESS Tender

NTPC Green Energy Limited 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 in Gujarat. The Khavda BESS tender marks one of India’s largest standalone battery energy storage initiatives aimed at strengthening grid reliability and renewable energy integration.

The company has invited bids under a turnkey Engineering, Procurement, and Construction (EPC) package. Bid submissions for the Khavda BESS tender will remain open until June 5, 2026.

Comprehensive EPC Scope Under Tender

The scope of the Khavda BESS tender includes:

Designing, Engineering, Supply, Packing and forwarding, Transportation, Installation, Testing, Commissioning, and Grid integration of the Battery Energy Storage System.

The selected bidder will also be responsible for integrating the BESS with associated Balance of System (BoS) infrastructure and connected solar plants to ensure seamless operation with the grid.

In addition, the project includes comprehensive operation and maintenance (O&M) responsibilities along with warranty and annual maintenance contract/service level agreement (SLA) support for a period of 15 years.

Strict Performance and Capacity Requirements

Under the Khavda BESS tender, bidders must guarantee a minimum dispatchable capacity of 92% at the Point of Interconnection (POI) throughout the 15-year operational period.

The tender specifies that the system must begin operations with 100% rated dispatchable capacity at the Commercial Operation Date (CoD) and maintain 95% capacity during the first year. At the time of project handover, dispatchable capacity must remain at or above 92%.

Any augmentation required to maintain these performance standards will fall under the bidder’s scope of work.

The minimum monthly Round Trip Efficiency (RTE), including auxiliary consumption measured at the termination point or point of coupling, must remain at 80%. The project also carries an annual availability requirement of 98%.

Long Design Life and Battery Specifications

According to the tender conditions, the design life of the complete BESS system, including batteries, must be 25 years from the commissioning date.

The battery systems offered under the Khavda BESS tender must support a minimum of 10,000 operating cycles while considering daily single-cycle operation and degraded capacity parameters proposed by bidders.

The latest Khavda BESS project further strengthens NTPC Green’s growing presence in India’s battery energy storage segment. Earlier, NTPC awarded a 50 MW/100 MWh BESS EPC contract worth approximately ₹108 crore to SolarWorld Energy for the Feroze Gandhi Unchahar Thermal Power Station in Uttar Pradesh.
