India Reaches 50% Renewable Energy Milestone, Solar Energy Takes Center Stage
India is making significant strides in its clean energy transition, with the Government of India's Department of Atomic Energy announcing an additional 13,600 MW of nuclear power capacity currently under implementation. This is part of India's broader ambition to expand non-fossil fuel power capacity to 500 GW by 2030, and potentially even 600 GW to meet surging electricity demand sustainably.
India's clean energy transition, however, faces several challenges. Distribution companies (discoms) in India carry heavy debt, which affects their financial health and ability to purchase electricity reliably from clean energy producers. This undermines their capacity to support renewable energy integration and disincentivizes investments in green power.
Physical limitations in the transmission and distribution infrastructure also delay the integration of renewable capacity. Issues include grid congestion, land procurement problems for transmission lines, and a lack of adequate storage solutions to manage the variability of renewables. These factors slow down the evacuation of solar and wind power to demand centers.
Despite these challenges, India is taking steps to address these issues. Addressing discom debt through financial restructuring, improved tariff setting, and operational reforms can improve their viability, encouraging more stable renewable energy purchases. Development finance interventions, such as the $2.4 billion India received for renewables, help bridge financing gaps.
Expanding and modernizing the grid, enhancing cross-state coordination, and investing in energy storage technologies are essential to overcome grid delays and integrate large shares of solar and wind power. Reducing bureaucratic delays related to land acquisition and environmental clearances will help lower project costs and speed up installation timelines.
India is not only focusing on solar and wind energy but is also investing in hydro, biomass, green hydrogen, and nuclear to diversify its clean energy mix and improve grid stability and supply reliability. Private investment in nuclear power generation has now been enabled within the current legal framework to support the establishment of Bharat Small Reactors (BSRs).
Flagship programs such as PM Surya Ghar: Muft Bijli Yogana, rooftop solar subsidies, and the PM-KUSUM scheme have accelerated solar adoption in India. Green hydrogen pilot projects using electrolysis powered by solar and wind have begun in India.
The RAPS-7 reactor (700 MW) was successfully connected to the grid on March 17, 2025, increasing the total number of operational nuclear reactors in India to 25, with a combined capacity of 8,880 MW. As of June 2025, nuclear energy provides a steady source of low-emission electricity with 8.8 GW of capacity.
India's total installed power generation capacity reached 476 GW in June 2025, with 83 percent of India's power sector investment in 2024 going to clean energy. Domestic solar module production capacity jumped from 2.3 GW to 88 GW, and cell production rose from 1.2 GW to 25 GW. In FY 2024-25 alone, 23.83 GW of solar was added in India.
Once these projects are completed, India's total nuclear capacity is expected to reach 22,480 MW by 2031-32. India allows 100 percent FDI in power generation and transmission, except in nuclear energy. Non-fossil fuel sources contributed nearly 49 percent of India's power generation in June 2025.
Hydropower in India stands at 48 GW, up from 35.8 GW in 2014. Biomass and biogas power contribute 11.6 GW in India. India became the world's largest recipient of development finance for clean power in 2024. Over the past five years, India recorded the third-largest growth in power generation capacity globally.
However, challenges remain. As of March 2025, electricity distribution companies (discoms) owed more than USD 9 billion in unpaid bills, and their total losses had reached USD 75 billion by 2023. Poor transmission infrastructure is holding back progress, with about 60 GW of renewable power capacity ready but unable to be used fully due to grid limitations.
In conclusion, India's clean energy transition requires a multi-pronged approach targeting discom financial health, grid modernization, and project economics to realize its ambitious renewable capacity goals and ensure a sustainable, reliable power future.
India's strategy for clean energy expansion involves several avenues beyond solar and wind, including investments in hydro, biomass, green hydrogen, and nuclear power to diversify its renewable-energy mix and enhance grid stability. (renewable-energy, India, clean energy, investment)
Despite receiving development finance of $2.4 billion for renewables, financing gaps still exist, which development finance interventions aim to bridge. (development finance, renewables, finance)
The Government of India's policy focus extends beyond nuclear power and includes addressing discom debt through financial restructuring and operational reforms to improve their capacity to buy electricity reliably from clean energy producers.

India's renewable-energy industry will need to navigate ongoing challenges, such as discoms accumulating more than $9 billion in unpaid bills and 60 GW of renewable power capacity being ready but unable to be used fully due to grid limitations, to achieve its ambitious clean energy capacity goals.
