Indian Cement Makers Expand Solar and Waste Heat Recovery to Cut Power Costs and Emissions

Shree Cement and JK Lakshmi Cement are scaling up renewable energy and waste heat recovery to reduce electricity costs and carbon emissions. JK Lakshmi already meets 47% of its power needs from green sources and plans to exceed 70% by FY30, including a 29 MW solar project with battery storage at Sirohi. Shree Cement raised its green power share to 62.1% in FY2025-26 and avoided about 1.05 million tonnes of CO2, while investing Rs 387.73 crore in energy conservation that delivered Rs 97.41 crore in annual savings. The broader Indian cement industry still relies on renewables for just 4-5% of its electricity mix, though it sees potential to reach 80-85% by 2070. Challenges remain: land availability, intermittent power, high capital costs for waste heat recovery (Rs 10-12 crore per MW vs Rs 4-6 crore for conventional), and weak transmission infrastructure near remote plants. The sector is also pushing for policy certainty, affordable green finance, and better grid access to accelerate the shift.

Good to see Indian cement companies treating green power as a cost play, not just a compliance box. JK Lakshmi at 47% green electricity and targeting 70% by FY30 is a concrete number. The 29 MW solar plus storage at Sirohi is worth watching, storage economics on industrial sites are still tricky.

Storage helps, but the real bottleneck is grid access. Many cement plants are in remote areas with weak transmission. The article says 80-85% renewable share possible by 2070, that's a long timeline. What matters is whether DISCOMs can absorb variable power and if land for solar scales near plants.

The Rs 10-12 crore per MW for waste heat recovery vs Rs 4-6 for conventional is a big gap. Without tax breaks or green finance, many plants will stick with grid power. Also note the CMA's 10% thermal substitution rate, that's still low. Policy needs to make alternative fuels cheaper than coal.

Shree Cement's numbers are the real story. Rs 387 crore invested, Rs 97 crore annual savings. That's a solid payback period. The 1.05 million tonnes CO2 avoided is meaningful. More companies should publish this kind of cost-benefit detail instead of vague net-zero pledges.
