India’s renewable energy sector continued its rapid growth in the first half of 2025, with solar and wind capacity installations surging. India installed 18 GW of solar capacity in H1 2025, marking a 31% increase year-over-year, with 11.3 GW added in Q2 alone – a 66.9% rise quarter-over-quarter and a 145.4% jump compared to Q2 2024. By June 2025, India’s cumulative installed solar capacity reached 116.4 GW, with large-scale projects accounting for 86% of this capacity.
On the wind energy front, India added 1.6 GW of new capacity in Q2 2025, more than doubling the 769 MW installed in Q2 2024, although this figure was 13% lower than Q1 2025. Gujarat led wind capacity additions for the quarter with 1.14 GW, followed by Karnataka with 364 MW. The country’s total installed wind capacity rose to 51.6 GW by June 2025.
Despite strong installation numbers, both solar and wind sectors faced challenges, including transmission bottlenecks, grid connectivity delays, land acquisition hurdles, and delays in power purchase agreements. The market is also transitioning toward storage, round-the-clock supply, and hybrid projects to improve grid integration and minimise curtailment risks.
As of mid-2025, India’s renewable energy capacity, including large hydro, accounted for approximately 48.3% of the country’s total installed power capacity, with a combined renewable portfolio of about 234 GW. The strong pipeline of nearly 191 GW in large-scale solar projects and ongoing wind initiatives indicate robust growth ahead for India’s clean energy transition.
