UltraTech Cement has commissioned 116.55 MW of wind capacity at its Inter-State Transmission System (ISTS)-connected wind-solar hybrid project in Barmer, Rajasthan, taking its cumulative installed green energy capacity to 2,024 MW.
The company has also commissioned 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works, its integrated manufacturing unit in Karnataka. The additions make UltraTech the first cement company in India to commission more than 2 GW of green energy capacity for captive use.
UltraTech’s current green energy portfolio comprises 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity. Together, these sources meet around 48% of the company’s current power requirements.
The company said the milestone is part of its multi-pronged energy transition strategy. During FY27 so far, nearly one-third of its 76 manufacturing units in India have maintained green energy utilisation above 50% of their electricity requirements, while five units have recorded utilisation levels above 95%.
UltraTech commissioned 430 MW of green energy capacity during FY26 and is continuing to expand its renewable energy and WHRS portfolio. The company is also progressively integrating Battery Energy Storage Systems (BESS) across its operations to increase renewable energy utilisation and improve power supply reliability.
In 2025, UltraTech operationalised an on-site hybrid round-the-clock renewable energy project at its Sewagram Cement Works in Gujarat. The project combines solar, wind and battery storage to support a more reliable renewable power supply for the manufacturing unit.
K C Jhanwar, Managing Director, UltraTech Cement, said crossing the 2 GW green energy milestone was the result of a strategy pursued consistently over the past decade. He said the company’s increasing use of renewable energy, waste heat recovery and battery storage was aimed at building a stable energy base while reducing exposure to fossil fuel supply constraints and fluctuations in power prices.
As part of its decarbonisation strategy, UltraTech has not invested in new captive thermal power capacity for more than 10 years, including for greenfield projects and brownfield expansions at its integrated units.
The company is targeting an 85% share of green energy in its total power mix by 2030. Separately, as a member of the RE100 initiative, UltraTech has committed to meeting 100% of its electricity requirements through renewable sources by 2050.
The latest commissioning strengthens UltraTech’s captive green power portfolio as the cement manufacturer continues to increase the role of renewable energy, waste heat recovery and energy storage across its manufacturing operations.
