UltraTech Surpasses 2 GW Green Energy Capacity: Key Facts for Exam Learners

UltraTech Cement Limited announced on 5 October 2026 that its cumulative installed green energy capacity for captive use has reached 2,024 MW, crossing 2 gigawatts (GW). The company says it is the first cement company in India to do so. This is a completed commissioning announcement as of 6 October 2026, but the "first" claim comes from the company's own press release and is repeated by GKToday. The supplied evidence has no independent verification of it.

What happened and when

The company's press release is dated Mumbai, 5 October 2026. GKToday's summary carries the same date. For exam notes, treat 5 October 2026 as the announcement date, and note that the evidence does not give separate commissioning dates for the individual projects.

The announcement covered two new additions:

• 116.55 MW of wind capacity at an Inter-State Transmission System (ISTS)-connected wind-solar hybrid project in Barmer, Rajasthan.
• 10 MW of Waste Heat Recovery System (WHRS) capacity at Sarlanagar Cement Works, an integrated manufacturing unit in Karnataka.

With these additions, the company reports a total of 2,024 MW.

The numbers at a glance

The two components add up to the total (1,580 MW + 444 MW = 2,024 MW). Since 1 GW equals 1,000 MW, 2,024 MW is just over 2 GW.

Key terms explained

Captive use

Captive power is electricity a company generates or procures for its own operations rather than for general sale. It is common in energy-intensive industries such as cement, steel and aluminium.

Waste Heat Recovery System (WHRS)

A WHRS captures heat that an industrial process would otherwise release and uses it to generate electricity. The company counts this as green energy alongside wind and solar.

ISTS-connected hybrid project

The Barmer project is described as a wind-solar hybrid connected to the Inter-State Transmission System. The evidence does not give the project's total size or its solar capacity, so this note does not state them.

Battery Energy Storage Systems (BESS)

The company says it is progressively adding battery storage to improve how much renewable power it can use and how reliable its supply is. It also says it operationalised an on-site hybrid round-the-clock renewable project combining solar, wind and battery storage at Sewagram Cement Works, Gujarat, in 2025. It describes this as the first of its kind in India. That is a company claim.

Why it matters

Cement is an energy-intensive sector that is hard to decarbonise. The company argues that green power lowers its dependence on grid and fossil-fuel electricity and reduces its exposure to coal and power price swings. It also says it has made no new captive thermal power investment, in greenfield or brownfield projects, for more than ten years. These are company statements, and the evidence includes no independent assessment of their effect on costs or emissions.

For learners, the story fits topics such as industrial decarbonisation, energy security and corporate climate commitments.

Plant-level use and targets

• In FY27 so far, nearly one-third of the 76 units have kept green energy above 50% of their electricity needs.
• Five of those units have exceeded 95%.
• UltraTech aims for green energy to make up 85% of its total power mix by 2030.
• As a member of RE100, it has committed to meeting 100% of its electricity requirement from renewable sources by 2050. RE100 is a global corporate initiative for 100% renewable electricity use.

The 2030 and 2050 targets are goals, not achievements. The 48% figure is the share of current power requirements, not the share of a fixed year's total consumption, and the evidence does not specify the measurement period.

Exam-oriented points to remember

• UltraTech reports 2,024 MW of captive green energy capacity: 1,580 MW renewable and 444 MW WHRS.
• The new additions are 116.55 MW wind in Barmer, Rajasthan, and 10 MW WHRS at Sarlanagar, Karnataka.
• The company claims to be the first Indian cement company above 2 GW of captive green energy capacity.
• Targets: 85% green energy in the power mix by 2030, and 100% renewable electricity by 2050 under RE100.

This note does not claim that any question on this topic will appear in an exam. Current-affairs questions can be framed in several ways, so check the figures and the "first" claim against your preferred sources.

What the evidence does not tell us

• It does not independently verify the "first in India" claim.
• It does not break down the 1,580 MW by wind, solar or hybrid, or give the company's total power demand in MW.
• It does not give generation output, emissions reductions or project costs.
• GKToday says the company "crossed" 2 GW, while the press release says it commissioned "over 2 GW" of capacity. Both refer to installed capacity, which differs from actual electricity generated.
