India’s installed power capacity crosses 513 GW by end-2025

India’s installed electricity generation capacity crossed 513 GW by the end of 2025, with renewable sources, including large hydro, accounting for nearly half the total, according to the latest Central Electricity Authority (CEA) report.

The country’s total capacity stood at 513,729.69 MW, or about 513.7 GW, as of December 31, 2025. Thermal power, predominantly coal, remains the backbone of the generation fleet, contributing 246.94 GW. Renewable energy sources, when including large hydroelectric projects, together formed a substantial and growing portion at 258.01 GW.

Ownership and fuel mix

Private sector developers hold the largest share of the country’s power capacity at 282.05 GW. Central government utilities, such as NTPC, account for 119.72 GW, while state-owned companies account for 111.96 GW.

Within the thermal segment, coal-based plants dominate with 219.61 GW. Gas- and lignite-based capacity stood at 20.12 GW and 6.62 GW, respectively, with diesel a marginal contributor.

Renewable energy capacity under the Ministry of New and Renewable Energy (MNRE) framework, which excludes large hydro, reached 207.09 GW. Solar power is the largest renewable component at 135.81 GW, followed by wind at 54.51 GW.

Regional disparities

The Western Region, comprising major industrial states like Gujarat and Maharashtra, holds the highest capacity at 175.24 GW. It features a near-equal split between thermal at 84.40 GW and renewables at 87.60 GW, with the private sector dominating ownership.

The Southern Region, a renewable energy leader, has a total capacity of 143.45 GW. Renewable sources command 80.42 GW, heavily driven by wind and solar installations in Tamil Nadu and Karnataka.

The Northern Region’s capacity stands at 150.78 GW, with renewables contributing 79.47 GW. States like Rajasthan and Uttar Pradesh are significant contributors.

In contrast, the Eastern Region, rich in coal reserves, remains heavily reliant on thermal power, which constitutes 31.16 GW of its 38.73 GW total. The North-Eastern Region at 5.36 GW and the island territories at 0.16 GW have minimal capacity shares.

Recent additions and adjustments

During December 2025 alone, India added a net 3,986.60 MW of capacity. Renewable energy projects constituted the bulk of this, with 3,486.60 MW added. Conventional capacity saw a net addition of 500 MW.

The financial year 2025–26 saw the commissioning of several major projects. These included state-run NHPC’s 200 MW Parbati-II hydro unit and Nuclear Power Corporation of India Ltd’s 700 MW Rajasthan atomic power unit in April 2025.

NTPC commissioned multiple 660 MW coal-based units at plants such as North Karanpura and Barh. Significant pumped storage capacity also came online, including units at THDC’s 250 MW Tehri project and Greenko’s Pinnapuram project.

The CEA data also noted the temporary removal of 1,995 MW of coal-based capacity, 4,400.84 MW of gas-based capacity, and 100 MW of nuclear capacity from the installed figures, effective May 31, 2025. These long-outage units will be reinstated once generation resumes.
