India’s leading cement manufacturers are increasingly integrating renewable energy into their core operations, shifting from ESG compliance-driven adoption to a direct profitability and margin protection strategy. Companies such as Shree Cement Limited, Ambuja Cements Limited, and Sagar Cements Limited are expanding investments in solar power, wind energy, and waste heat recovery systems (WHRS) to reduce energy costs and hedge against fuel price volatility.
The trend reflects a structural shift in the cement sector, where energy is one of the largest input costs. Companies are now treating renewable energy not just as a sustainability initiative, but as a key operational lever to improve EBITDA margins.
Among industry leaders, Shree Cement has emerged as a frontrunner in green energy adoption. The company reported that its share of green electricity in total consumption rose to 61% in Q4 FY26, compared to 59% in the same period last year. The company’s renewable portfolio now stands at 666.5 MW, reflecting steady expansion in captive and clean energy assets.
At Ambuja Cements, management has highlighted that increasing renewable energy usage is expected to generate significant cost savings. The company estimates potential savings of ₹150–₹200 per tonne from improved green energy utilization and efficiency gains. Its green power share has already increased to 32% in Q4 FY26, up from 26% previously, with a long-term target of reaching 60% by FY28 through solar, wind, and WHRS expansion.
Sagar Cements is also strengthening its focus on energy efficiency, with renewable energy and WHRS positioned as key drivers of margin improvement. The company recently commissioned 2.8 MW of waste heat recovery capacity and is progressing toward completing its total 4.35 MW WHRS project. Management expects these initiatives, along with solar integration, to materially enhance profitability in the coming quarters.
Across the sector, the shift toward captive renewable energy is reshaping cost structures and improving long-term competitiveness. With rising power demand and fluctuating fossil fuel prices, cement companies are increasingly viewing clean energy investments as a strategic necessity rather than a compliance requirement.
