UltraTech Cement has commissioned 116.55 MW of wind capacity at its Inter-State Transmission System-connected wind-solar hybrid project in Barmer, Rajasthan, taking its cumulative installed green energy capacity to 2,024 MW. The company said this makes it the first cement manufacturer in India to commission more than 2 GW of green energy capacity for captive use.

The company has also commissioned 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works, its integrated manufacturing unit in Karnataka. UltraTech’s total green energy capacity comprises 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity.

Green power currently meets about 48 per cent of UltraTech’s power requirements. During FY27, nearly a third of its 76 manufacturing units in India have maintained green energy utilisation above 50 per cent of their electricity needs, while five units have exceeded 95 per cent.

UltraTech commissioned 430 MW of green energy capacity in FY26 and is progressively integrating Battery Energy Storage Systems (BESS) across its operations to improve renewable energy utilisation and supply reliability. In 2025, it operationalised an on-site hybrid round-the-clock renewable energy project at Sewagram Cement Works in Gujarat, combining solar, wind and battery storage.

The company has not invested in new captive thermal power capacity for greenfield projects or brownfield expansions at its integrated units for more than ten years. It aims to increase green energy’s share of its total power mix to 85 per cent by 2030. Separately, as a member of RE100, UltraTech has committed to meeting its entire electricity requirement through renewable sources by 2050, reducing its exposure to fossil fuel supply constraints and power price volatility.
