India’s installed power generation capacity is expected to more than double to 1,121 GW by 2035-36, according to the National Generation Adequacy Plan (2035-36) released by the Central Electricity Authority, thereby reflecting a major expansion in the country’s energy sector over the next decade.
The projected capacity marks a sharp rise from around 520 GW as of January 2026, underscoring the scale of anticipated additions across both conventional and renewable energy sources.
As per the report, the total installed capacity by 2035-36 will comprise 315 GW of coal, 20 GW of gas, 22 GW of nuclear, and 78 GW of large hydro. Renewable energy is expected to form a significant portion, with solar capacity projected at 509 GW and wind at 155 GW, along with 16 GW of biomass and 6 GW of small hydro.
The projections indicate a shift towards cleaner energy, with non-fossil fuel-based capacity expected to reach about 786 GW, accounting for nearly 70 per cent of the total installed capacity by 2035-36. This is a notable increase from around 52 per cent in January 2026.
In contrast, the share of fossil fuel-based capacity is expected to decline to about 30 per cent from 48 per cent over the same period.
The plan also envisages a significant build-out of energy storage infrastructure, with total storage capacity estimated at 174 GW/888 GWh by 2035-36. This includes Battery Energy Storage Systems (BESS) of 80 GW/321 GWh and Pumped Storage Projects (PSP) of 94 GW/567 GWh.
The projections are part of long-term planning efforts aimed at ensuring resource adequacy and meeting the country’s growing electricity demand while accelerating the transition towards cleaner energy sources.
