As India’s heavy industries pivot toward low-carbon operations, the domestic cement sector is making major strides in renewable adoption. A recent report by rating agency ICRA reveals that major cement manufacturers are on track to scale their green power capacity from approximately 4.0 GW (as of March 2026) to 5.8–6.0 GW by March 2028.
This transition is powered by planned investments of Rs 12,000–13,000 crore over the next two years. Beyond meeting long-term net-zero goals, the shift is commercially compelling: the new renewable capacity is projected to generate annual savings of Rs 6,200–6,700 crore, offering a swift payback period of just 1.8 to 2.2 years.
How the Industry and Consumers Benefit
- Substantial Cost Savings and Margin Boost: Cement manufacturing is notoriously energy-intensive. According to ICRA insights, every 5% increase in green power replacement lowers power and fuel costs by Rs 15–16 per tonne. Achieving a 25% replacement level translates into direct savings of Rs 75–80 per tonne, supporting an operating margin expansion of 140 to 160 basis points.
- Mitigating Price Volatility: Transitioning to renewables shields cement producers from traditional fuel price volatility and supply-side risks, ensuring more stable pricing structures over the long term.
- Tackling Emission Hotspots: While the calcination process accounts for 57–60% of total emissions, fuel combustion (27–30%) and electricity consumption (10–13%) are being actively managed through aggressive green power adoption, alternative fuels, and clinker efficiency.
- Unlocking Alternative Fuels: India’s current thermal substitution rate (TSR) sits at roughly 6%, leaving significant room for growth compared to global benchmarks. Major producers are targeting TSR levels of 10–15% over the next 3 to 5 years by adopting biomass, municipal waste, and industrial waste.
- Rise of Green Financing: To fund this massive transition, leading cement firms are increasingly tapping into sustainability-linked bonds, green loans, and specialized financing avenues for renewable projects and waste heat recovery systems.
