UltraTech becomes India’s first cement company to surpass 2 GW of captive green energy capacity

UltraTech Cement has crossed the 2 GW mark in installed green energy capacity, becoming the first cement company in India to commission more than 2,000 MW of green energy capacity for captive use.

The Aditya Birla Group company said it has commissioned 116.55 MW of wind capacity as part of 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 in Karnataka.

With these additions, UltraTech’s cumulative installed green energy capacity has reached 2,024 MW, comprising 1,580 MW of renewable energy capacity and 444 MW of WHRS capacity. The portfolio now meets about 48% of the company’s power requirements.

Nearly half of power needs met through green energy

The milestone comes as UltraTech steps up its energy transition strategy across its manufacturing footprint. In FY27 so far, nearly a third of its 76 manufacturing units in India have maintained green energy utilisation at more than 50% of their electricity requirement, with five units exceeding 95%.

“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.

“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.

UltraTech commissioned 430 MW of green energy capacity in FY26 and is continuing to expand its renewable energy and WHRS portfolio. The company is also progressively integrating battery energy storage systems 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 its Sewagram Cement Works in Gujarat. The project combines solar, wind and battery storage to provide a more reliable renewable power supply.

Targets 85% green power by 2030

UltraTech said its green energy investments are aimed at reducing its dependence on conventional grid power and fossil fuel-based electricity while lowering its exposure to volatility in coal and electricity prices. The company has not invested in new captive thermal power capacity for more than a decade, either for greenfield projects or brownfield expansions at its integrated manufacturing units.

UltraTech aims to raise the share of green energy in its total power mix to 85% by 2030. Separately, as a member of the RE100 initiative, it has committed to meeting 100% of its electricity requirements through renewable sources by 2050.

The company said the expansion of its green energy portfolio is also intended to strengthen energy security across its operations while supporting India’s broader transition towards greater energy self-reliance.
