UltraTech Cement has become the first Indian company to cross 2 GW of captive green power capacity after commissioning a 116.55-MW wind energy project in Barmer, Rajasthan, marking a significant milestone in the cement maker’s energy transition strategy. The Aditya Birla Group flagship said its cumulative installed green energy capacity has now reached 2,024 MW, comprising 1,580 MW of renewable energy capacity and 444 MW of Waste Heat Recovery System (WHRS) capacity. Together, these sources meet around 48 per cent of UltraTech’s current power requirements, reducing its dependence on conventional energy and strengthening its focus on lower-carbon manufacturing. Alongside the Rajasthan wind project, the company commissioned 10 MW of WHRS capacity at Sarlanagar Cement Works, its integrated manufacturing unit in Karnataka. The latest additions build on a broader programme to expand renewable power and recover energy from industrial processes across its manufacturing network. UltraTech commissioned 430 MW of green energy capacity during FY26 and continues to develop renewable energy and WHRS projects to increase the contribution of green power in its overall electricity mix. The company is also progressively deploying Battery Energy Storage Systems across its operations to improve renewable energy utilisation and enhance power supply reliability. In 2025, UltraTech operationalised what it described as India’s first on-site hybrid round-the-clock renewable energy project at Sewagram Cement Works in Gujarat. The project combines solar power, wind energy and battery storage, enabling the company to use renewable electricity more consistently across its operations. The latest milestone comes as UltraTech increases green energy utilisation at its manufacturing facilities. During FY27 so far, nearly one-third of the company’s 76 manufacturing units in India have maintained green energy utilisation above 50 per cent of their electricity requirements. Five units have recorded green energy utilisation of more than 95 per cent, underlining the progress made at individual plants. UltraTech’s decarbonisation strategy also extends to its approach to captive thermal power. The company said it has not invested in new captive thermal power capacity for more than a decade, whether for greenfield projects or brownfield expansions at its integrated units. This approach reflects its longer-term effort to increase the share of renewable and recovered energy while limiting additions to carbon-intensive power infrastructure. The company’s growing green power portfolio is particularly significant given the energy-intensive nature of cement manufacturing, where electricity and fuel consumption are major contributors to operating emissions. By expanding captive renewable capacity and WHRS installations, UltraTech aims to improve energy efficiency, reduce reliance on conventional power and support its sustainability objectives. UltraTech Cement, a USD 10 billion building solutions company, is the largest cement company globally by sales volume outside China. It has total grey cement capacity of 210.1 MTPA and white cement and putty capacity of 3.5 MTPA. The company’s 2,024-MW green energy portfolio underscores its ambition to integrate renewable power more deeply into its large-scale manufacturing operations while advancing its long-term decarbonisation goals. The milestone also strengthens UltraTech’s position among industrial companies pursuing large-scale captive renewable energy adoption in India for long-term operations.
