NTPC Renewable Energy Limited (NTPC REL) has invited bids for the development of a 240 MW/960 MWh Inter-State Transmission System (ISTS)-connected Battery Energy Storage System (BESS) at its Devikot Solar Plant in Rajasthan. The tender, issued under reference number NREL-CS-5824-004(BESS1)-9, seeks an Engineering, Procurement and Construction (EPC) contractor for the large-scale energy storage project.
The scope of work includes the design, engineering, supply, installation, testing and commissioning of the Battery Energy Storage System, along with associated power evacuation and grid integration infrastructure. The selected bidder will also be responsible for long-term operations and maintenance (O&M) of the facility.
According to the tender specifications, the battery storage system is expected to have a design life of up to 25 years and support a minimum of 10,000 charge-discharge cycles during its operational life. The project is aimed at enhancing grid reliability, improving renewable energy integration and supporting the growing deployment of utility-scale clean energy infrastructure across India.
NTPC REL has outlined technical and financial qualification requirements for prospective bidders. Eligible participants must demonstrate prior experience in executing large-scale power, renewable energy or energy storage projects, along with the capability to undertake EPC activities involving design, engineering, procurement, construction, testing and commissioning. Bidders must also satisfy the financial criteria specified in the tender documents.
Battery Energy Storage Systems are increasingly becoming a critical component of India’s energy transition strategy, enabling the efficient management of intermittent renewable energy sources such as solar and wind power. By storing excess electricity and supplying power during peak demand periods, BESS projects help improve grid flexibility, stability and energy security.
The Devikot Battery Storage Project represents another significant step in NTPC REL’s efforts to expand India’s utility-scale energy storage capacity and support the country’s renewable energy ambitions.
