Non-fossil power generation nears one-third of India’s total electricity output

Electricity generation from non-fossil fuel sources — including wind, solar, hydro, and nuclear — is steadily approaching one-third of India’s total power output, driven by rapid growth in renewables and hydropower.

Between April and September 2025, non-fossil generation stood at 301.3 billion units (BU), accounting for 31.3% of India’s total 962.53 BU output, up from 27.1% in the same period last year, according to data from the Central Electricity Authority (CEA).

While large hydro generation rose 13.2% year-on-year, other renewable sources — primarily wind and solar — surged 23.4%. Nuclear output, however, dipped 3.7%.


Among states, Gujarat led with 36.19 BU of renewable power generation, followed by Rajasthan (35.87 BU), Himachal Pradesh (33.53 BU), Tamil Nadu (32.08 BU), and Karnataka (31.35 BU).

The rise in clean energy output comes as India’s installed non-fossil capacity crosses 250 GW, marking significant progress toward the country’s 2030 target of 500 GW. As of September 2025, total installed capacity stood near 500 GW, with 197 GW from renewables alone — up from just 35 GW in 2014.

In October, India allocated 3.6 GW of renewable capacity and 6 GWh of energy storage, while the sector drew $1.2 billion in fresh investments, according to JMK Research.
