Midwest Gold Subsidiary Commences BESS Operations in Bengaluru

The clean energy firm hits a milestone as its battery storage facility begins production, targeting grid-scale and commercial energy markets.

BENGALURU – Midwest Energy Devices Private Limited, a clean energy technology subsidiary of Midwest Gold Limited, has officially commenced operations at its new lithium battery assembly facility in Bengaluru. The milestone marks a significant expansion for the company as it enters the Battery Energy Storage System (BESS) market with an initial annual capacity of 1 GWh.

The semi-automated manufacturing plant, which began trial runs earlier this year, is now integrated into the company’s broader clean-energy value chain. This facility is designed to support a roadmap for scaling production up to 3 GWh annually, addressing the growing demand for energy storage in India’s renewable energy and industrial sectors.

Scaling Battery Energy Storage Systems

The Bengaluru facility serves as the primary hub for the company's BESS platform development. According to official disclosures, the plant is currently producing two flagship energy storage solutions:

• Outdoor BESS Units: A 418 kWh system designed specifically for commercial, industrial, and distributed energy applications.

• Containerized BESS Systems: A 5 MWh platform engineered for large-scale grid deployments, renewable energy integration, and grid support applications.

These systems are built to meet rigorous global certification standards, including UL 1973, UL 9540, and UL 9540A, ensuring that the technology aligns with international safety and reliability benchmarks. Each unit produced at the facility is backed by a 12-year warranty on both the system and the individual cells.

Strategic Infrastructure and Quality Control

The manufacturing platform is built around process-driven rigor and traceability. Every incoming battery cell undergoes verification through customized cycler infrastructure before entering the assembly process. Once assembled, every finished storage unit is subjected to a comprehensive series of end-of-line and end-of-cycle tests to validate performance and safety.

The facility’s flexible design allows for the handling of various cell types and pack configurations. This versatility enables Midwest Energy to provide solutions ranging from branded BESS products to contract manufacturing and customized battery pack requirements for diverse markets.

Why It Matters

As India accelerates its transition toward renewable energy, the need for robust energy storage has become a critical supply chain priority. By localizing the production of grid-scale and commercial battery systems, Midwest Gold Limited is positioning itself to support the national "Make in India" initiative. The company’s move into BESS manufacturing helps integrate its energy storage capabilities with its existing rare earth materials and mineral exploration ventures, creating a more cohesive footprint in the clean-tech ecosystem.

Official Sources

The commencement of commercial production was disclosed in accordance with Regulation 30 of the SEBI Listing Regulations. Official updates regarding manufacturing capacities, certifications, and operational roadmaps have been filed with the BSE Limited.

"According to officials," the Bengaluru facility is designed not just for simple assembly, but to deliver fully integrated systems wherein safety, performance, and manufacturability are addressed collectively to meet the stringent demands of the grid-scale energy market.
