en.Wedoany.com Reported - India's renewable energy generation (including large hydropower) increased by 18.68% year-on-year in May 2026, primarily driven by a significant surge in solar power output. According to the latest government data, renewable energy generation reached 47,317.5 million units in the month, up from 39,869.3 million units in the same period in 2025, accounting for 26.65% of the total electricity generation of 177.56 billion units. Excluding large hydropower, renewable energy generation stood at 34,565.16 million units, a stronger year-on-year growth of 29.92%.
Solar power was the largest contributor to India's renewable energy mix in May, with generation surging 50.88% year-on-year to 21,583.99 million units from 14,305.32 million units in May 2025. It accounted for 45.6% of total renewable energy generation (including large hydropower) and contributed 12.16% to the country's total electricity generation that month. As of May 31, 2026, India's installed solar capacity reached 157.05 GW, underscoring the sector's growing importance in the country's power structure.
Large hydropower was the second-largest source of renewable energy, though its generation declined 3.86% year-on-year to 12,752.34 million units from 13,264.60 million units last year. It still accounted for 26.95% of India's renewable energy generation and 7.18% of total electricity generation. As of the end of May, installed large hydropower capacity stood at 51.96 GW.
Wind power generation increased 7.41% year-on-year to 11,458.18 million units from 10,667.42 million units in May 2025, contributing 24.2% of renewable energy generation and 6.45% of India's total electricity generation. As of the end of May, India's installed wind power capacity reached 56.81 GW.
Small hydropower generation continued to lag, declining 20.49% year-on-year to 620.92 million units from 780.91 million units, accounting for only 1.31% of renewable energy generation and 0.35% of total electricity generation that month. Biomass and bagasse power generation saw modest growth, with biomass generation rising 6.58% to 383.27 million units and bagasse generation increasing 7.10% to 256.39 million units. Together, they generated 639.66 million units, contributing 1.35% of renewable energy generation and 0.51% of India's total electricity generation.
The latest data highlights solar power's growing dominance in India's renewable energy landscape. In May, solar and wind power together generated 33.04 BU (billion units), accounting for nearly 70% of India's renewable energy generation that month. The robust growth in renewable energy generation also reflects the rapid expansion of clean energy capacity, with the solar sector increasingly becoming a cornerstone of India's energy transition.
