Pace Digitek operationalized BESS manufacturing facility with installed capacity of 2.5 GWh during FY26. It has also delivered 178 BESS containers during FY26, which was a record; there is no other company which has manufactured 178 containers within India.

The company also successfully executed 480 megawatt hours (MWh) of utility-scale BESS capacity during FY26. It is in the process of expanding its manufacturing capacity from 2.5 GWh to 5 GWh. The machinery and equipment have been received, installation is underway, and the 5 GWh facility is expected to be operational from July 2026 onwards.

In addition to this 5 GWh capacity, Pace Digitek has completed the necessary infrastructure and plant construction for expansion to 10 GWh. It has also placed orders for 5 GWh production lines and which are expected to be operational in October 2026.

#3 JSW Energy

Next on our list is the stock of JSW Energy. The company is a major player in the power generation space.

Coming to energy storage - JSW Energy was the first to recognise the critical role it plays in integrating renewable energy and ensuring grid stability.

The locked-in storage capacity of the company now stands at 29.6 GWh, of which 3.2 GWh are in BESS and 26.4 GWh in the remunerative Pumped Hydro space.

Further, the 5 GWh battery assembly facility in Pune was commissioned in Q4 FY26, and the commercial sales of the battery storage have already commenced. This plant will position JSW Energy to meet domestic content requirements for BESS as and when mandated by the Government of India.

The management in a recent earnings conference call indicated that Energy storage, including BESS is fast becoming a mainstream infrastructure investment and JSW Energy is well ahead of the market in building this capability.

Additionally, the company's Blade manufacturing facility at Halol, scheduled for commissioning in the first half of FY27, would provide advantage to the company in terms of lower capital cost for wind projects due to savings in logistics cost and foreign exchange, thereby strengthening its vertical integration.

Financial Snapshot of JSW Energy

Revenue for Q4 FY26 grew 39% YoY to Rs 48.51 bn, a trajectory firmly anchored in the robust expansion of its generation capacity.

Profit After Tax came in at Rs 5.74 bn, up 38% year-on-year.

According to management, the significant capacity additions the company has executed over the past several quarters are now clearly translating into higher generation volumes and stronger cash flows. They expect this momentum to build further through into FY27.

Conclusion

BESS stocks offer investors exposure to one of the fastest-growing segments of the clean energy transition.

As renewable energy capacity expands, efficient energy storage will play a critical role in ensuring grid stability, improving power reliability, and enabling greater integration of solar and wind energy. Government policy support, declining battery costs, and rising investments in grid infrastructure further strengthen the sector's long-term outlook.

However, investors should focus on companies with proven execution capabilities, strong order books, technological expertise, and healthy financials. A diversified approach can help capture the sector's growth potential while managing the risks associated with an evolving industry.
