India achieved its highest-ever annual renewable energy capacity additions in calendar year 2025 (January–December), adding nearly 37.9 GW of solar and 6.3 GW of wind capacity, according to official data. Compared to CY2024, solar installations rose by 54.7 per cent, while wind capacity additions surged by 85.3 per cent, marking a sharp acceleration in the country’s clean energy deployment.
Data released by the Ministry of New and Renewable Energy (MNRE) shows that India’s total installed renewable energy capacity reached approximately 258 GW as of December 2025. Solar energy emerged as the dominant contributor, accounting for around 53 per cent of the total renewable energy mix. Wind power followed with 21 per cent, while large hydro contributed 20 per cent, bio power 4 per cent, and small hydro 2 per cent.
Utility-scale solar remained the primary growth driver in 2025, with India adding about 28.6 GW of new capacity—an increase of 54.6 per cent over the previous year. The sharp rise was largely attributed to the commissioning of long-pending projects awarded by central and state agencies. Developers also accelerated project execution ahead of the Inter-State Transmission System (ISTS) waiver deadline, which encouraged faster installations. The open access segment played a significant role, accounting for over 38 per cent of total utility-scale solar additions during the year.
The expansion of domestic solar manufacturing further supported capacity growth, with cumulative module and cell manufacturing capacity crossing 200 GW by December 2025.
Rooftop solar installations also witnessed strong momentum, with around 7.9 GW added in 2025, representing a 72 per cent increase over CY2024. Nearly 60 per cent of these additions were recorded in the second half of the year, driven primarily by the rollout of the PM Surya Ghar: Muft Bijli Yojana.
In contrast, the off-grid and distributed solar segment saw a marginal slowdown, with approximately 1.35 GW added in 2025—about 8.8 per cent lower than installations recorded in the previous year.
The wind energy sector recorded a strong recovery, with around 6.3 GW of new capacity added in 2025, nearly double the 3.4 GW installed in 2024. Growth in the segment was largely led by open access projects, which accounted for 60–70 per cent of total wind capacity additions during the year.
On a state-wise basis, Gujarat, Rajasthan, Maharashtra, Karnataka, and Tamil Nadu together accounted for approximately 83.7 per cent of India’s total solar and wind installations in 2025. Gujarat led the additions with around 11.1 GW, followed by Rajasthan (10.2 GW) and Maharashtra (9.7 GW), highlighting the continued dominance of these states in India’s renewable energy expansion.
