UltraTech Cement has crossed 2 GW of captive green energy capacity, with renewables and waste heat recovery meeting 48 per cent of its power needs.

Mumbai

UltraTech Cement Limited has surpassed 2 GW of installed green energy capacity for captive use, becoming the first cement company in India to achieve the milestone. The Aditya Birla Group company commissioned 116.55 MW of wind capacity at its Inter-State Transmission System-connected wind-solar hybrid project in Barmer, Rajasthan, along with 10 MW of Waste Heat Recovery System capacity at Sarlanagar Cement Works in Karnataka.

With these additions, UltraTech’s cumulative installed green energy capacity has reached 2,024 MW. This includes 1,580 MW of renewable energy capacity and 444 MW of waste heat recovery capacity, together meeting around 48 per cent of the company’s current power requirements.

The company said the milestone reflects the progress of its long-term energy transition strategy. In FY27 so far, nearly one-third of UltraTech’s 76 manufacturing units in India have maintained green energy utilisation above 50 per cent of their electricity requirements, while five units have crossed 95 per cent.

K C Jhanwar, Managing Director, UltraTech Cement Limited, said, “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. 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.”

UltraTech commissioned 430 MW of green energy capacity in FY26 and continues to expand its renewable energy and waste heat recovery portfolio.

The company is also progressively integrating Battery Energy Storage Systems across its operations to improve renewable energy utilisation and 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, wind and battery storage.

As part of its decarbonisation strategy, UltraTech said it has not invested in new captive thermal power capacity for either greenfield projects or brownfield expansions at its integrated units for more than a decade.

The company said its expanding green energy portfolio is helping reduce dependence on conventional grid electricity and fossil fuel-based power, while lowering exposure to fluctuations in coal and electricity prices.

UltraTech aims to increase green energy’s share in its total power mix to 85 per cent by 2030. As a member of RE100, it has also committed to meeting 100 per cent of its electricity requirement through renewable sources by 2050.

UltraTech Cement, the cement flagship of the Aditya Birla Group, has a total grey cement capacity of 210.1 MTPA and white cement and putty capacity of 3.5 MTPA. The company is also a signatory to the GCCA Climate Ambition 2050 and has committed to the GCCA Net Zero Concrete roadmap.
