India’s energy storage sector is experiencing unprecedented momentum, with the cumulative stationary energy storage market soaring from 122 GWh to 224 GWh in just one year, according to India Energy Storage Alliance (IESA). The project pipeline has “rapidly expanded”, with 60 GWh under execution, 80 GWh in various tendering stages, and 35 GWh already awarded, says a statement from IESA. The total pipeline of BESS projects now stands at 92 GWh, while pumped storage projects (PSP) have surged from 50 GWh to 132 GWh since last year. With India set to commission nearly 5 GWh of new capacity this year, an almost tenfold jump in installed capacity, the sector is poised for a breakthrough year.

IESA says 69 new BESS tenders, totalling 102 GWh, were issued in the past year, marking a 35 per cent jump over 2024 and nearly doubling the annual tender volume. Landmarks such as Adani’s entry with the world’s largest single-location BESS project, NTPC’s innovative long-duration storage demonstration and the upcoming launch of India’s largest solar+BESS tender in Rajasthan signal a rapidly maturing market. The stage is set for merchant BESS, thermal + BESS and new C&I applications to take off this year.

Against this backdrop, the alliance is set to unveil its white paper on the stationary energy storage market at the Stationary Energy Storage India (SESI) conference on March 20 in New Delhi, on the sidelines of the Bharat Electricity Summit. The event is expected to bring together more than 300 industry leaders, government officials and international partners from over 10 countries.

Eastman solar plant goes live

Eastman Auto & Power Limited has commissioned an 800-MW solar photovoltaic (PV) panel and module manufacturing facility in Sonipat, Haryana.

The company already manufactures products such as grid-tied, off-grid and hybrid inverters, and energy-storage batteries. With the new plant manufacturing solar panels and modules, the company said it intends to offer integrated systems, combining solar generation with storage for residential, commercial and industrial users.

Eastman said the facility would supply domestically manufactured solar modules, including those compliant with the domestic content requirement (DCR) norms in some government solar programmes.

The company operates in three segments — last-mile e-mobility, solar solutions and energy storage systems.

According to Managing Drector Shekhar Singal, the company is focusing on expanding domestic solar manufacturing and promoting integrated solar-plus-storage systems. He added that such systems could support rooftop solar adoption under schemes such as the PM Surya Ghar Muft Bijli Yojana.

The Sonipat facility adds to India’s growing domestic solar manufacturing capacity as the country seeks to expand renewable energy deployment and reduce dependence on imported modules.

Test rig for wind power gear

Flender India, a part of the Flender Group headquartered in Bocholt, Germany, announced the launch of India’s largest and most advanced ‘test rig’ for wind-power gearboxes in Walajabad. Technically, the test rig sets new standards; the centre support transmits a torque of up to 18,000 kNm. The plate field is designed for tensile and compressive forces of up to 500 tonnes, says a press release.
