Wedoany.com Report on Feb 2nd, Power Grid Corporation of India Limited recently initiated a tender for a battery energy storage project in Telangana, aimed at enhancing grid stability and supporting renewable energy development. The project involves constructing a standalone large-scale battery energy storage system at the Maheswaram substation in southern India, as part of a plan to utilize idle land for a total storage capacity of 1,500 MWh.

The specific package in this tender is named "Telangana-BESS Package 01," which includes constructing a 187.5 MW battery system with an energy storage capacity of 750 MWh. The system is designed for a 4-hour discharge duration, capable of providing continuous power at full capacity for 4 hours.

This battery energy storage project will help improve the stability of the regional power grid. By storing excess electricity during peak generation periods from solar and wind power, the system can release power during peak demand hours, alleviating grid pressure, enhancing power supply reliability, and promoting the utilization of variable renewable energy.

The project is implemented through a tariff-based global competitive bidding process to ensure transparency and value for money. The work falls under the engineering category in the power energy sector and is open to eligible bidders nationwide.

According to the tender schedule, the notice was issued on January 14, 2026, and the sale of tender documents closed on January 19, 2026. Bidders must submit their electronic bids by 11:00 AM on January 21, 2026, with the bid opening planned for 11:30 AM on the same day.
