UltraTech Cement, Peers Plan ₹13,000 Crore Green-Power Push to Boost Margins By 160 Bps

Market snapshot: India's leading cement manufacturers, including UltraTech Cement, Ambuja Cements, and Dalmia Bharat, are launching a massive green power transition. Backed by planned capital expenditures of ₹12,000 crore to ₹13,000 crore over the next two years, these majors aim to raise their cumulative green power capacity to nearly 5.8 GW to 6.0 GW by March 2028. This capital commitment is geared toward lowering power and fuel costs, mitigating risks from volatile fuel prices, and achieving long-term net-zero targets.

Data Snapshot

• India's leading cement players plan to invest ₹12,000 crore to ₹13,000 crore over the next two years to raise green power capacity to 5.8–6.0 GW by March 2028.
• Every 5% increase in green power replacement reduces fuel and power costs by ₹15 to ₹16 per tonne, while a 25% replacement can expand operating margins by 140 to 160 basis points.
• During the first quarter of fiscal 2027, green power met approximately 47% of UltraTech Cement's total energy requirements.

What's Changed

• Industry green power capacity is projected to increase by nearly 50% to reach 5.8–6.0 GW by March 2028, up from around 4.0 GW recorded as of March 2026.
• Operating margins are expected to benefit from a structural expansion of 140 to 160 basis points, driven by unit cost savings of ₹75 to ₹80 per tonne.

Key Takeaways

• Cement manufacturers are accelerating their transition to captive green power to hedge against persistent fuel price volatility and supply-side risks.
• The planned green energy capacity additions offer highly attractive economics, with an estimated annual cost savings of ₹6,200 crore to ₹6,700 crore and a payback period of 1.8 to 2.2 years.
• Every 5% replacement of conventional energy with green power reduces fuel and power costs by ₹15 to ₹16 per tonne, providing an immediate margin cushion.
• UltraTech Cement remains at the forefront of this shift, with green power already making up 47% of its total energy requirements in the first quarter of fiscal 2027.

SAHI Perspective

From an investment and operational standpoint, the cement sector's green-energy push represents a fundamental shift from purely regulatory sustainability to absolute margin preservation. In a highly capital-intensive and cyclical commodity business, power and fuel represent the single largest variable cost. By locking in renewable capacities and leveraging waste heat recovery systems, market leaders are structurally lowering their cost curves. For UltraTech Cement, its established scale and existing 47% green energy mix allow it to command superior unit economics, meaning it can maintain profitability even during periods of weak cement realizations.

Market Implications

The market implications are two-fold: First, we expect a structural widening of the EBITDA margin gap between the top-tier cement companies and smaller players who lack the capital to invest in captive green power. Second, this massive capital expenditure will generate robust demand for renewable energy components, wind and solar project developers, and waste heat recovery equipment manufacturers over the next 24 months.

Trading Signals

Market Bias: Bullish

The planned green-power push by cement majors is a structural catalyst that can boost operating margins by up to 160 basis points through cost savings of ₹75 to ₹80 per tonne. This cost-efficiency drive, paired with UltraTech Cement's strong Q1 FY27 PAT growth of 17% YoY, supports a positive outlook.

Overweight: Cement, Renewable Energy, Capital Goods

Underweight: Thermal Power Utilities

Trigger Factors:

• Decline in coal and petcoke import prices
• Aggressive commissioning of waste heat recovery systems (WHRS) and solar power plants
• Pace of retail cement price recovery in the second half of fiscal 2027

Time Horizon: Medium-term (3-12 months)

Industry Context

The Indian cement industry is the second largest globally, and it remains highly emission-intensive. In cement manufacturing, the calcination process contributes 57% to 60% of total emissions, while fuel combustion and electricity account for around 27% to 30% and 10% to 13%, respectively. Over the past two years, the sector has witnessed rapid consolidation, with the top four players projected to expand their market share from 48% in fiscal 2024 to 61% by fiscal 2030, reinforcing their capacity to undertake major sustainability-led capex.

Key Risks to Watch

• Delay in executing renewable energy and transmission grid integration projects.
• Prolonged price wars or weak demand in key housing and infrastructure markets, which could offset margin gains.
• Changes in state-level policies or open-access charges for renewable energy transmission.

Recent Developments

In July 2026, UltraTech Cement reported its Q1 FY27 financial results, posting a 17.2% year-on-year increase in consolidated net profit to ₹2,604 crore and a 15.8% increase in revenue from operations to ₹24,648 crore. In the same quarter, green power met approximately 47% of the company's total power requirements. Additionally, the company is preparing to launch its wires and cables business in the third quarter of fiscal 2027, with a total planned investment of ₹1,800 crore.

Closing Insight

While short-term cement pricing volatility remains a key monitorable, the industry's multi-billion-crore transition to captive green energy will permanently reshape its cost structures. For long-term investors, players like UltraTech Cement, which possess both the scale to deploy this capital and a proven operational track record, offer resilient margin profiles in a consolidation-driven market.
