UltraTech Cement Ltd, an Aditya Birla Group company and the world’s largest cement company excluding China, has crossed the 2 GW milestone in installed green energy capacity for captive use, after commissioning 116.55 MW of wind capacity at its Inter-State Transmission System (ISTS)-connected wind-solar hybrid project in Barmer, Rajasthan.
The company has also commissioned 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works, its integrated manufacturing unit in Karnataka.
Green energy meets 48% of power needs
With these commissioning milestones, UltraTech’s cumulative installed green energy capacity has increased to 2,024 MW, comprising 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity.
The combined green energy portfolio now meets around 48% of UltraTech’s current power requirements, making it the first cement company in India to commission more than 2 GW of green energy capacity for captive use.
The company said the milestone reflects the cumulative impact of its multipronged energy transition strategy.
In FY27 so far, nearly one-third of UltraTech’s 76 manufacturing units in India have maintained green energy utilisation at more than 50% of their electricity requirement. Five of these units have exceeded 95% green energy utilisation.
UltraTech targets 85% green energy by 2030
“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,” UltraTech Cement Limited, Managing Director, K C Jhanwar, said.
“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,” Jhanwar added.
UltraTech commissioned 430 MW of green energy capacity in FY26 and is continuing to expand its portfolio of renewable energy and WHRS projects.
The company is also progressively integrating Battery Energy Storage Systems (BESS) across its operations to improve renewable energy utilisation and supply reliability.
Hybrid renewable energy and storage
In 2025, UltraTech operationalised what it described as India’s first on-site hybrid round-the-clock renewable energy project, combining solar, wind and battery storage at its integrated manufacturing unit, Sewagram Cement Works in Gujarat.
As part of its decarbonisation strategy, UltraTech has also not invested in new captive thermal power capacity for more than a decade, either for greenfield projects or brownfield expansions at its integrated units.
The company said its green energy portfolio strengthens energy security across its manufacturing footprint by reducing dependence on conventional grid power and fossil fuel-based electricity, while lowering exposure to coal and electricity price volatility.
RE100 commitment
UltraTech aims 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 requirement through renewable sources by 2050.
The company said its green energy transition demonstrates how energy-intensive industries can integrate renewable energy into operations while maintaining operational reliability and supporting long-term growth.
