Power Grid Corporation of India Limited (POWERGRID) has invited bids for the development of a 500 MW / 1000 MWh Battery Energy Storage System (BESS) project across India, marking another major step in the country’s efforts to strengthen its electricity grid and support the growing share of renewable energy. The project will be executed under a Long-Term Agreement (LTA) and falls under Category-A, which is designed for a two-hour battery energy storage system.
According to the official tender notice, the selected developer will be responsible for the complete design, engineering, supply, erection, testing, and commissioning of the battery energy storage systems at multiple locations across the country. The project will be implemented on a site-destination basis, ensuring the deployment of large-scale storage infrastructure that can enhance grid reliability and improve the integration of renewable energy sources.
As India continues to expand its solar and wind power capacity, battery energy storage systems are becoming increasingly important for maintaining grid stability. These systems store excess electricity generated during periods of high renewable energy production and supply it back to the grid during peak demand or when renewable generation declines. Such projects are expected to play a crucial role in improving power reliability and supporting the country’s clean energy transition.
The tender, identified by Specification Reference Number CC/T/W-BESS/DOM/A04/26/09605, has been issued as an open competitive bidding process under the Works category in the Power and Energy sector. POWERGRID is conducting the entire procurement process through its digital e-tendering platform, the PRANIT Portal, under RFX Number 5007000201.
The sale of tender documents began on July 16, 2026, at 11:30 PM. Interested bidders can participate in a pre-bid meeting scheduled for July 28, 2026, at 11:30 AM, where they will have an opportunity to seek clarifications regarding the project scope and bidding requirements.

The notice does not mention a specific Performance Bank Guarantee (PBG), with detailed financial and contractual requirements expected to be provided in the complete tender documents available through the PRANIT Portal.
The tender process is being overseen by Rohit Dalakoti, Chief Manager at POWERGRID. Administrative correspondence related to the project will be handled from the company’s headquarters at Saudamini, Sector 29, Gurugram, Haryana. Since the project will be implemented across multiple states, it is expected to significantly strengthen India’s power infrastructure while supporting the country’s long-term renewable energy and energy storage objectives.
