India’s power sector, the country’s largest carbon emitter, must secure a massive $700 billion investment over the next decade to support its transition towards net-zero emissions by 2070, according to Moody’s Ratings. Currently, the sector contributes around 37% of India’s total carbon emissions. The investment required between fiscal 2026-2051 is estimated at 1.5-2% of GDP, which Moody’s considers manageable for the country.

India’s electricity generation remains heavily dependent on coal, making significant decarbonization investments essential for meeting emission reduction targets. Moody’s predicts that India’s strong economic growth over the next ten years will drive an increase in coal-based power generation, complicating the nation’s transition to cleaner energy sources.
To achieve its energy transition goals, India’s power sector will require annual investments ranging between ₹4.5 lakh crore to ₹6.4 lakh crore (US$ 53 billion to US$ 76 billion) until fiscal 2034-35, totaling around US$ 700 billion over ten years. Between 2026-2051, annual investment needs will rise to ₹6 lakh crore to ₹9.5 lakh crore.
These investments will finance electricity generation, transmission, distribution, and energy storage. Renewable energy, including solar and wind power, will dominate capacity additions over the next two to three decades, with smaller contributions from nuclear and hydropower. Grid network expansion and energy storage projects will also be key areas of focus.
Power Demand Growth and Future Capacity Expansion
India’s economy is expected to grow at an average rate of 6.5% per year over the next decade, leading to a compound annual growth rate of 6% in power demand. With per capita electricity consumption at 1,255 kWh in fiscal 2022, just a third of the global average, demand is set to rise further as India’s economy expands and living standards improve.
Moody’s projects that India will add 450 GW of renewable energy capacity during this period, but even this expansion will fall short of meeting rising electricity demand. As a result, coal-based power generation capacity will increase by 35%, from 218 GW to 295 GW by 2035. Meanwhile, installed generation capacity will double by 2034-35, with non-fossil fuel sources contributing 45-50% of total power output, up from 23.5% in 2023-24.
Role of Private and Foreign Investment
The private sector will play a crucial role in India’s clean energy transition. Moody’s expects private companies to remain highly active in renewable energy investments, while government-owned entities will also expand their presence. Foreign investment will be essential in bridging funding gaps, as domestic financial institutions alone cannot meet the long-term capital needs of the sector.
Conventional bank loans and non-banking financial institutions (NBFCs) will provide debt capital for projects under construction. For operational projects, debt capital markets—both domestic and international—will be critical for refinancing. However, India must secure low-cost, long-term foreign capital to address financing shortfalls effectively.
India’s power sector faces a dual challenge—expanding capacity to meet surging electricity demand while reducing reliance on fossil fuels. Despite its ambitious renewable energy targets, coal will continue playing a significant role in the country’s energy mix over the next decade. The transition will require unprecedented investments from both public and private sources, along with substantial foreign capital infusion. With the right policies and financial mechanisms in place, India can achieve its clean energy goals while sustaining its economic growth.
