UltraTech green energy capacity reached 2,024 MW, the cement maker said in a BSE filing on October 5, 2026, after commissioning wind and waste heat recovery capacity. The Aditya Birla Group company said it had become India's first cement producer to surpass 2 GW of installed green energy capacity for captive use.

The additions comprise 116.55 MW of wind capacity at its Inter-State Transmission System-connected wind-solar hybrid project in Barmer, Rajasthan, and 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works.

UltraTech's installed green energy portfolio now includes 1,580 MW of renewable energy and 444 MW of WHRS capacity. Together, these meet about 48% of its current power requirements, according to the filing.

Manufacturing units expand green power use

In FY27 so far, nearly a third of UltraTech's 76 manufacturing units in India have maintained green energy utilisation above 50% of their electricity requirements. Five units have exceeded 95%.

Managing Director K C Jhanwar said the transition reflected a strategy pursued over the past decade. He said meeting nearly half the company's power needs through green energy had reduced its exposure to fossil fuel supply constraints and power price volatility.

The company outlined further progress across its energy portfolio:

  • It commissioned 430 MW of green energy capacity in FY26.
  • It is progressively integrating Battery Energy Storage Systems across operations to improve renewable energy utilisation and supply reliability.
  • In 2025, it operationalised what it described as India's first on-site hybrid round-the-clock renewable energy project at Sewagram Cement Works in Gujarat, combining solar, wind and battery storage.

85% green energy target for 2030

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

The company said it had not invested in new captive thermal power capacity for more than ten years, including for greenfield projects and brownfield expansions at its integrated units. It continues to advance renewable energy and WHRS projects to increase green energy's share in its power mix.
