UltraTech Cement Limited announced on 5 October 2026 that its cumulative installed green energy capacity has reached 2,024 MW. It describes itself as the first cement company in India to commission more than 2 GW. For a sector that depends on large amounts of heat and electricity, the company says the capacity now covers close to half of its power needs.
The numbers behind the milestone
One gigawatt equals 1,000 megawatts, so 2,024 MW is just over two gigawatts of generating capacity built for the company’s own use. According to the company, this comprises 1,580 MW from renewable sources and 444 MW from waste heat recovery systems (WHRS). WHRS units generate electricity from heat that cement plants would otherwise release.
The latest additions were 116.55 MW of wind capacity at a grid-connected wind-solar hybrid project in Barmer, Rajasthan, and 10 MW of WHRS capacity at Sarlanagar Cement Works in Karnataka.
The share of power that is green has risen. At 31 March 2026, captive green capacity stood at 1,806 MW and met 41% of power requirements. The current capacity meets about 48%. In everyday terms, almost one unit of electricity in every two used across the company’s plants now comes from renewable or waste-heat sources.
The picture differs from plant to plant. In FY27, nearly a third of UltraTech’s 76 manufacturing units in India have kept green energy above 50% of their electricity use, and five units have gone beyond 95%. One of them is the Kukurdih Cement Works in Chhattisgarh. UltraTech says it has met all of its electricity needs there through renewable power and waste heat recovery in every month since April 2026.
What comes next
The company has set longer-term goals. Under its RE100 commitment, UltraTech aims to raise green power to 85% of its electricity mix by 2030 and 100% by 2050. That means closing a gap of 37 percentage points in the next four years.
Two other steps support the plan. The company is deploying battery energy storage systems to support greater use of renewable power. It has also not invested in new captive thermal power capacity for greenfield projects or brownfield expansions at its integrated units for more than a decade.
What this means for India
Cement is a core input for housing and infrastructure, and UltraTech says it operates 76 manufacturing units across India. Its 2,024 MW is a company-reported figure, but it shows how one large producer is cutting its reliance on thermal electricity. Wind capacity in Rajasthan and waste heat recovery in Karnataka show that both new renewable projects and efficiency measures at existing plants can contribute. Other Indian manufacturers can compare their own green-power shares against the 48% reported here.
The figures come from company announcements and have not been independently audited. The company’s waste heat recovery capacity is counted within its “green” total. The 2030 and 2050 targets are goals, not commitments with a guaranteed outcome.
