India’s Energy Capacity May Surpass Double By 2036, Says Report

 India's power generation capacity is projected to more than double to 1,121 gigawatts by 2035-36, driven primarily by a massive expansion in renewable energy sources. The Central Electricity Authority's National Generation Adequacy Plan, released on March 19, 2026, at the Bharat Electricity Summit, outlines this ambitious growth from the current 520.5 gigawatts.

Non-fossil fuels are expected to constitute nearly 70% of the total, reaching 786 gigawatts, with solar capacity surging to 509 gigawatts and wind to 155 gigawatts. Coal-based capacity will remain significant at 315 gigawatts to ensure grid reliability amid rising demand.

Peak power demand is forecasted to hit 459 gigawatts by 2035-36, up from 250 gigawatts in 2024, reflecting India's economic expansion and electrification push. Total energy requirements could reach 3,365 billion units annually, necessitating robust storage solutions like 174 gigawatts/888 gigawatt-hours from batteries and pumped hydro. This includes 80 gigawatts/321 gigawatt-hours from battery energy storage systems alone.

The plan builds on recent records, with India adding 52.5 gigawatts in the current financial year, 43 gigawatts from renewables, already surpassing 50% non-fossil capacity nationally. Ongoing projects include 155 gigawatts of renewables under construction and 41 gigawatts of coal, alongside nuclear expansions totaling 13.6 gigawatts. The Green Energy Corridor Phase III scheme targets an additional 134 gigawatts of renewables.

This transition supports India's net-zero emissions goal by 2070, balancing clean energy dominance with baseload stability from hydro, nuclear, and coal. Energy storage growth addresses intermittency challenges, ensuring 24/7 supply as peak loads strain existing infrastructure. States like Rajasthan, India's renewable leader, may still add coal capacity for grid stability despite solar-wind booms.

The projections signal complete visibility for capacity additions, prioritizing cost-effective pathways amid global energy shifts and domestic industrialization. With over half of current capacity already non-fossil, India positions itself as a renewable superpower while safeguarding energy security through diversified sources.
