Solar Companies Expand Storage Capabilities with Battery Energy Systems.

As India continues to add renewable energy capacity at a record pace, solar energy companies are increasingly investing in Battery Energy Storage Systems (BESS) manufacturing to address the growing need for reliable power storage and grid stability.

Leading solar module manufacturer Waaree Energies has set a target of achieving 20 gigawatt-hours (GWh) of BESS capacity by FY28. The planned capacity will cover the manufacturing of battery cells, battery packs and utility-scale BESS containers.

Through its subsidiary, Waaree Energy Storage Solutions, the company has proposed a capital expenditure of ₹10,000 crore for its battery storage business, including the establishment of an ₹8,000-crore battery gigafactory in Andhra Pradesh. Waaree expects to operationalise 3.5 GWh of BESS production capacity by FY27.

Meanwhile, Kolkata-based Vikram Solar has outlined plans to build 15 GWh of BESS capacity by 2030. The company will initially focus on assembling battery packs and containerised energy storage systems using externally sourced cells before gradually expanding into integrated battery cell manufacturing.

Vikram Solar has also announced plans to develop 7.5 GWh of battery cell manufacturing capacity as part of its long-term strategy to strengthen its presence across the energy storage value chain.

The investments reflect the increasing importance of battery storage in India's renewable energy transition, as developers seek solutions to manage intermittency and support round-the-clock clean power supply.
