UltraTech Cement Limited has commissioned 116.55 MW of wind capacity at its inter-state transmission system (ISTS)-connected wind-solar hybrid project in Barmer, Rajasthan, and 10 MW of waste heat recovery system (WHRS) capacity at Sarlanagar Cement Works in Karnataka. With these additions, UltraTech’s cumulative installed green energy capacity has reached 2,024 MW, making it the first cement company in India to cross 2 GW of green energy capacity for captive use.
The company’s current green energy portfolio consists of 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity. Together, these sources meet about 48% of UltraTech’s current power requirements. The latest milestone is part of the company’s energy transition programme, which includes investments in renewable energy, waste heat recovery and battery energy storage systems (BESS).
“Crossing the 2 GW green energy milestone is the result of a strategy we have pursued consistently over the past decade. Cement is an energy-intensive, hard-to-abate sector, and showing that reliability and growth can go hand in hand with a rapid shift to green energy sets a benchmark for the industry,” said K C Jhanwar, Managing Director, UltraTech Cement Limited.
“With nearly half of our power needs now met through green energy, we are significantly less exposed to fossil fuel supply constraints and power price volatility. As we scale up renewables, waste heat recovery and battery storage across our operations, we are building an energy foundation for stable, long-term growth,” he added.
In FY27 so far, nearly one-third of UltraTech’s 76 manufacturing units in India have maintained green energy utilisation above 50% of their electricity requirements. Five of these units have recorded green energy utilisation of more than 95%. UltraTech commissioned 430 MW of green energy capacity in FY26 and continues to add renewable and WHRS capacity across its manufacturing network. The company is also progressively deploying BESS to increase renewable energy utilisation and improve the reliability of power supply.
In 2025, UltraTech operationalised an on-site hybrid round-the-clock renewable energy project at Sewagram Cement Works in Gujarat. The project combines solar and wind generation with battery storage. The company has not invested in new captive thermal power capacity for more than 10 years, either for greenfield projects or brownfield expansions at its integrated manufacturing units.
UltraTech plans to increase the share of green energy in its total power mix to 85% by 2030. Separately, as a member of RE100, the company has committed to meeting 100% of its electricity requirements through renewable sources by 2050. UltraTech said its green energy portfolio is helping reduce dependence on conventional grid and fossil fuel-based power while limiting exposure to fluctuations in coal and electricity prices. UltraTech Cement is the cement flagship company of the Aditya Birla Group. It has a total grey cement capacity of 210.1 MTPA and white cement and putty capacity of 3.5 MTPA.
