New Delhi: India added nearly 37.9 GW of solar and 6.3 GW of wind capacity in calendar year 2025, marking the country’s highest-ever annual renewable energy additions, according to a report released by JMK Research on Tuesday. Compared to 2024, solar capacity additions rose by 54.7 percent, while wind installations increased by 85.3 percent. The report noted that “India recorded its highest-ever annual renewable energy additions in CY2025 (January–December).”

As per data released by Ministry of New and Renewable Energy (MNRE) till December 2025, India’s cumulative renewable energy installed capacity reached around 258 GW.
“Solar energy contributes approximately 53 percent of the total RE segment, making it the largest contributor,” the report said. Wind accounts for 21 percent, followed by large hydro at 20 percent, bio power at 4 percent and small hydro at 2 percent.
India added about 28.6 GW of new utility-scale solar capacity in 2025, a rise of about 54.6 percent compared to 2024 installations. JMK Research attributed the surge primarily to “the commissioning of the long pending tenders awarded by various central and state agencies to the RE developers.” It added that “swift project execution due to the ISTS waiver deadline encouraged developers to fast-track installation activities.”
The open access segment emerged as a key growth driver, accounting for “more than 38 percent of the total utility-scale solar installations during this year.”
The report said the expansion of domestic manufacturing also supported solar growth, with “cumulative manufacturing capacity of modules and cells crossing the 200 GW mark by December 2025.”
India added about 7.9 GW of rooftop solar capacity in 2025, a 72 percent increase compared to 2024. Nearly 60 percent of these installations were commissioned in the second half of the year.
“This growth can be attributed to the launch of the PM Surya Ghar: Muft Bijli Yojana,” the report said.
In the off-grid and distributed solar segment, around 1.35 GW was added in 2025, about 8.8 percent lower than the additions in 2024.
Wind capacity additions stood at about 6.3 GW in 2025, almost double the 3.4 GW added in 2024. According to the report, the increase was “mainly due to the dominance of open access capacity additions,” which accounted for more than 60–70 percent of wind installations during the year.

State-wise, Gujarat, Rajasthan, Maharashtra, Karnataka and Tamil Nadu together accounted for approximately 83.7 percent of India’s total solar and wind capacity additions in 2025.
“Gujarat led the installation tally for 2025 with around 11.1 GW installed capacity,” followed by Rajasthan at 10.2 GW and Maharashtra at 9.7 GW, the report said.
