Power Grid Corporation of India Limited has invited bids for a major battery energy storage project in Telangana, marking another important step in strengthening India’s power grid and supporting renewable energy growth. The tender relates to the development of a large standalone Battery Energy Storage System, or BESS, at the Maheswaram Substation in southern India. The project is part of a broader plan to create 1,500 MWh of storage capacity on vacant land owned by Telangana State Transmission Corporation Limited.
The specific package covered under this notice is known as “Package Telangana-BESS 01.” It involves setting up a 187.5 MW battery system with an energy storage capacity of 750 MWh. The system is designed with a four-hour discharge duration, which means it can deliver power continuously for four hours at full capacity.
This project will play an important role in improving grid stability in the region. By storing excess electricity generated from solar and wind sources during periods of high generation, the battery system can release power during peak demand hours. This helps reduce stress on the grid, improves reliability, and allows greater use of renewable energy, which is often variable in nature.
The project is being implemented through a Tariff Based Global Competitive Bidding process. This approach allows Power Grid to select developers based on the most competitive and efficient tariff offers, ensuring transparency and value for money. The work falls under the “Works” category in the power and energy sector and is open to eligible bidders from across the country.
According to the tender schedule, the notice was published on January 14, 2026. The sale of tender documents closed on January 19, 2026. Bidders are required to submit their bids in soft copy form by January 21, 2026, at 11:00 AM. The bids are scheduled to be opened on the same day at 11:30 AM.
To participate, bidders must pay a non-refundable tender fee of ₹25,000. The tender value has been indicated as zero in the initial notice. This usually means that the final project cost will be decided based on the tariffs discovered during the competitive bidding process, rather than being pre-defined.
The tender summary also mentions an Earnest Money Deposit of zero. However, bidders are advised to carefully review the full tender documents and pre-qualification criteria available on the PRANIT portal. In similar Power Grid projects, bidders are often required to submit a bid security declaration or provide a performance bank guarantee after the award of the contract. The performance bank guarantee typically ranges between 3 percent and 10 percent of the contract value and is meant to ensure the timely completion and reliable operation of the project.
Overall, the Telangana BESS project reflects Power Grid’s growing focus on energy storage as a key enabler of India’s clean energy transition.
