Power Grid Corporation of India Limited (POWERGRID) has invited bids for a major grid-scale Battery Energy Storage System (BESS) project, reinforcing India’s efforts to strengthen its electricity network and support the rapid growth of renewable energy. The state-owned transmission utility is seeking qualified partners under a Long Term Agreement (LTA) for the complete design, supply, erection, testing, and commissioning of a 250 MW/1000 MWh Battery Energy Storage System at multiple locations across the country.
The tender has been issued under an Open Tender format and falls under Category-B, which represents a 4-hour duration BESS. The project is expected to play an important role in improving grid stability, balancing renewable power generation, and ensuring a reliable electricity supply as India continues to increase its solar and wind energy capacity.
According to the tender documents, the selected contractor will be responsible for executing the project on an Engineering, Procurement, and Construction (EPC) basis. The scope of work includes the complete design, supply of equipment, erection, testing, and commissioning of the battery storage systems on a site-destination basis across various locations in India. The project aims to establish advanced energy storage infrastructure capable of storing surplus renewable energy and supplying it back to the grid during periods of high electricity demand. The procurement process is being conducted through POWERGRID’s PRANIT e-tendering portal, allowing bidders to submit their proposals electronically.
The tender was published on July 16, 2026, at 11:30 PM. The document sale period will remain open until August 17, 2026, at 11:00 AM. POWERGRID has scheduled a pre-bid meeting for July 28, 2026, at 11:30 AM, providing interested bidders with an opportunity to seek clarifications regarding the project requirements and bidding process.
The deadline for submitting soft copy bids is August 17, 2026, at 11:00 AM, while the bid opening is scheduled for the same day at 11:30 AM. According to the tender notice, there is no tender fee or earnest money deposit (EMD) specified. However, bidders have been advised to carefully review the detailed tender documents available on the PRANIT portal for any additional financial or bank guarantee requirements.
The tender has been issued by Rohit Dalakoti, Chief Manager at POWERGRID, with the authority’s office located at Saudamini, Plot No. 2, Sector 29, Gurugram, Haryana.
The project represents another significant milestone in India’s growing battery storage sector. Unlike conventional short-duration storage systems, the 4-hour BESS configuration provides extended energy storage capability, enabling better management of renewable energy variability and peak electricity demand. By establishing long-term supply and execution agreements, POWERGRID also aims to ensure timely project implementation while reducing risks associated with global battery supply chain uncertainties. The initiative is expected to strengthen the country’s power infrastructure and support India’s long-term clean energy and energy transition goals.
