UltraTech Cement has crossed the 2 GW mark in installed green energy capacity for captive use, becoming the first cement company in India to achieve the milestone.

The company recently commissioned 116.55 MW of wind capacity as part of its ISTS-connected wind-solar hybrid project in Barmer, Rajasthan, along with 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works in Karnataka.

With these additions, UltraTech’s total installed green energy capacity has reached 2,024 MW, comprising 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity. The portfolio currently meets around 48% of the company’s power requirements.

UltraTech commissioned 430 MW of green energy capacity during FY26 and continues to expand its renewable energy, waste heat recovery and battery storage capabilities. Nearly one-third of its 76 manufacturing units in India have already been meeting more than 50% of their electricity needs through green energy in FY27 so far, with five units crossing the 95% mark.

The company has also been integrating Battery Energy Storage Systems (BESS) to improve renewable energy utilisation and supply reliability. In 2025, UltraTech operationalised India’s first on-site hybrid round-the-clock renewable energy project combining solar, wind and battery storage at Sewagram Cement Works in Gujarat.

As part of its decarbonisation strategy, UltraTech has not invested in new captive thermal power capacity for more than a decade. The company aims to raise the share of green energy in its total power mix to 85% by 2030 and, as a member of RE100, has committed to meeting 100% of its electricity needs from renewable sources by 2050.
