UltraTech Cement’s captive green-energy capacity was reported at 2,024 MW on 5 October 2026, making it the first cement company in India to cross 2 GW, according to a ScanX / LiveSquawk report labeled AI-generated. That is not the same as a confirmed claim that UltraTech is the first Indian firm of any kind to reach the threshold. The latest company figure in the reviewed official material is 1,897 MW as of Q1FY27; the reported October additions have not been confirmed in the cited company release.
What UltraTech’s reported 2 GW capacity includes
The October report’s 2,024 MW total comprises 1,580 MW of renewable-energy capacity and 444 MW of waste heat recovery systems (WHRS). Renewable capacity includes solar, wind and hybrid power. WHRS captures heat from industrial processes and uses it to generate electricity; it is counted in UltraTech’s green-energy total, but it is a different technology from solar or wind.
The report attributes the increase to 116.55 MW of wind capacity in Rajasthan and 10 MW of WHRS capacity at Sarlanagar in Karnataka. These additions and the resulting total are reported figures, not confirmed in the official Q1FY27 release cited below.
How the reported total compares with company figures
| Figure | What it represents | Source and date |
|---|---|---|
| 2,024 MW | Reported captive green-energy capacity: 1,580 MW renewable plus 444 MW WHRS | ScanX / LiveSquawk, 5 October 2026; report labeled AI-generated |
| 1,897 MW | Official captive green-energy capacity: 1,463 MW renewable plus 434 MW WHRS | UltraTech Cement, Q1FY27 press release dated 28 September 2026 |
| More than 1,800 MW | FY26 green-energy capacity, including more than 1.39 GW renewable power and 414 MW WHRS | UltraTech Cement FY26 sustainability story, originally published 5 June 2026 and updated 10 August 2026 |
The official 1,897 MW figure is a Q1FY27 snapshot, so it does not rule out later additions. It does mean the October total and its component figures should remain attributed to the secondary report unless confirmed by a company or exchange filing.
#1 Best Overall
Does 2 GW mean 48% of UltraTech’s electricity is green?
No. Megawatts measure installed capacity, not the amount of electricity generated or consumed over a period. The October report says the reported capacity supplies around 48% of UltraTech’s current power requirements, but that is a separate claim from the capacity total.
For comparison, UltraTech reported a 35.8% green-power mix for FY26. The FY26 percentage and the October report’s “current” share refer to different dates and may use different denominators, so they are not a like-for-like measure of change.
Rank #2
How far has green-power use reached across its plants?
In its Q1FY27 release, UltraTech said nearly one-third of its 76 Indian manufacturing units had exceeded 50% green-energy utilisation since April 2026, while five units had exceeded 95%. Kukurdih Cement Works in Chhattisgarh, an integrated unit with capacity of 3.3 million tonnes a year, was reported to meet all its electricity requirements through green energy every month since April 2026, using renewable sourcing and WHRS. These are plant-level examples; they do not mean the entire company runs on green electricity.
One example of a different supply approach is the 7.5 MW on-site round-the-clock hybrid project at Sewagram Cement Works in Gujarat. UltraTech says it combines solar, wind and battery storage and was developed with clean-energy solutions company Gentari to supply power at that site without grid reliance. The project illustrates how technologies can be combined to address intermittency; it does not establish system-wide performance or economics.
What are UltraTech’s future green-power targets?
UltraTech’s stated targets are to reach 85% green power in its total power mix by 2030 and to meet 100% of its electricity requirements from renewable sources by 2050. These are future targets, not achieved results. The company also says it has not invested in new captive thermal power capacity for more than ten years.

UltraTech’s FY26 sustainability reporting provides wider context, but these figures should not be treated as effects caused solely by the reported 2 GW milestone. For FY26, the company reported 49.83 million tonnes of recycled and alternative raw materials used in cement production, a 6.6% thermal substitution rate, and gross emissions intensity of 578 kg CO₂ per tonne of cementitious products. The company says FY26 data includes acquired Kesoram Industries and India Cements operations; the emissions figure is gross intensity, not net intensity.
The company’s 13 December 2023 release attributed a statement about sustainability leadership to K C Jhanwar, then managing director: “As the largest cement company in the country, it is our responsibility to lead the way in building a more sustainable and green future for the industry.” That historical remark is not a comment on the October 2026 capacity report.
