UltraTech Cement has crossed 2 GW of installed green energy capacity for captive use, reaching 2,024 MW following the commissioning of new wind and waste heat recovery capacities. The company has become the first cement manufacturer in India to surpass the 2 GW milestone in captive green energy capacity.
The company has commissioned 116.55 MW of wind capacity at its Inter-State Transmission System (ISTS)-connected wind-solar hybrid project in Barmer, Rajasthan. It has also commissioned 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works, its integrated manufacturing unit in Karnataka.
With these additions, UltraTech’s total installed green energy capacity stands at 2,024 MW, comprising 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity. The capacity currently meets around 48% of the company’s total power requirements.
During FY27 so far, nearly one-third of UltraTech’s 76 manufacturing units in India have achieved green energy utilisation of more than 50% of their electricity requirements. Five manufacturing units have recorded green energy utilisation of more than 95%.
UltraTech commissioned 430 MW of green energy capacity in FY26 and is continuing to integrate Battery Energy Storage Systems (BESS) across its operations to increase renewable energy utilisation and improve power supply reliability.
In 2025, the company operationalised India’s first onsite hybrid round-the-clock renewable energy project at Sewagram Cement Works in Gujarat. The project combines solar, wind and battery storage to provide continuous renewable power.
UltraTech has not added new captive thermal power capacity for greenfield projects or brownfield expansions at its integrated units for more than a decade.
The company aims to increase the share of green energy in its overall power mix to 85% by 2030. As a member of RE100, UltraTech has also committed to meeting 100% of its electricity requirements from renewable sources by 2050.
