Mahanadi Coalfields Limited (MCL) has issued an Expression of Interest (EOI) inviting proposals for the deployment of a 60 MWh Battery Energy Storage System (BESS) in Odisha, marking a significant step toward integrating renewable energy into its operations and strengthening grid support capabilities.

The EOI is aimed at technology providers, EPC contractors and battery manufacturers with proven experience in utility-scale energy storage. Through this initiative, MCL intends to assess available technologies and implementation approaches for developing battery storage assets aligned with its sustainability roadmap.

Scope of the initiative

The proposed battery system is intended to support renewable-energy integration, provide operational flexibility and enhance power reliability across MCL’s infrastructure. The scope of the EOI covers:

Design, supply and integration of battery energy storage systems
Technology evaluation across commercially viable chemistries
Implementation models suitable for large utility operations
Long-term performance, safety and maintenance considerations

By inviting technical and financial inputs at the EOI stage, MCL aims to identify the most cost-effective and scalable pathway before proceeding with a formal tender.

Strategic importance

Battery storage has become a critical enabler for India’s clean-energy transition — particularly in regions with growing solar and wind capacity. Through the proposed 60 MWh system, MCL is positioning itself to:
