The minimum capacity for each bid is set at 100 MW/200 MWh. Developers selected through this process will be responsible for building, owning, and operating the BESS facilities. These systems must be made available to MSEDCL for charging and discharging on demand, enabling the utility to manage energy supply more effectively during peak and off-peak hours.
To facilitate project development, land for the BESS installations will be provided on a right-of-use basis, with a nominal annual lease rate of INR 1 per plot. MSEDCL will enter into a Battery Energy Storage Purchase Agreement (BESPA) with each successful bidder, formalizing the terms of energy storage availability and use.
Eligibility for participation in the tender is open to independent BESS developers and existing renewable energy developers with valid intra-state Power Purchase Agreements (PPAs). Renewable developers may establish DC-coupled BESS units co-located with their solar projects under the existing PPA. These co-located systems must be charged exclusively through the associated solar installations using DC-to-DC charging technology and must utilize the existing grid evacuation infrastructure.
MSEDCL’s initiative aims to enhance grid reliability, address fluctuations in electricity demand, and support the state’s transition toward a more flexible and resilient power system. By integrating large-scale storage, the utility seeks to balance renewable energy inputs and reduce dependence on conventional power during high-demand periods.
This tender represents a significant step in India’s broader energy transition strategy, particularly in advancing energy storage deployment. The project will contribute to the long-term goal of increasing the share of renewable energy in the electricity mix while ensuring grid stability and energy availability across Maharashtra.
