India is meeting its headline clean-energy targets years ahead of schedule, but the hardest parts of its energy transition still lie ahead, according to a new report from BloombergNEF.
The India Transition Factbook 2026, published on October 13 and commissioned by Bloomberg Philanthropies, gives one of the most comprehensive data-driven snapshots of where the world's most populous country stands on decarbonisation. It shows a nation that has become a global heavyweight in renewable energy deployment while still relying on coal for most of its electricity, with fast-rising demand from industry, transport and digital infrastructure.
The report's central message is that India's dual goals of expanding clean energy and cutting dependence on imported fossil fuels are increasingly aligned and economically viable.
Targets met ahead of time
The most striking finding concerns installed capacity. The share of non-fossil technologies on India's power grid, measured in capacity terms, crossed 50% in 2025. That is five years ahead of the target India set in its Nationally Determined Contribution under the Paris Agreement in 2022. BNEF projects that share will exceed 60% in 2028, seven years ahead of India's revised commitment.
Over the past decade, non-fossil technologies have accounted for 80% of all new power generation capacity added in the country. India was the world's second-largest market for annual solar and wind capacity additions in 2025, behind only China, and BNEF expects it to remain the second-largest solar market for the foreseeable future.
Investment has followed. Energy-transition investment in India reached $72 billion in 2025, about 1.7% of GDP, making the country the fifth-largest market for such investment globally. The wind and solar sectors alone will need between $123 billion and $163 billion of capital, in real 2025 dollars, through 2030.
Coal is still king
Capacity, however, is not the same as generation. Because solar and wind plants produce electricity only when the sun shines or the wind blows, their share of actual output is lower than their share of installed capacity. According to the report, non-fossil sources supplied about one-third of India's electricity demand in the first seven months of 2026. Coal still provides the majority, at roughly 68% of the country's electricity.
That gap explains much of the challenge ahead. India's power demand is growing quickly, and clean-energy additions must outpace that growth for coal's share to fall meaningfully. Transmission is a key constraint. India is the fourth-largest market for grid investment, and plans to build enough transmission by the first quarter of 2032 to connect 336 GW of renewable capacity, roughly twice the size of the UK's existing grid capacity. Delivering that build-out on time will be essential to avoid stranded solar and wind capacity.
Emissions and energy security
On emissions, the report offers cautious optimism. India's revised NDC targets a 47% reduction in the emissions intensity of its GDP by 2035, compared with 2005 levels. BNEF says that goal is achievable under its base-case scenario.
The energy-security argument may prove even more persuasive for policymakers. In BNEF's economics-led scenario, which assumes no new supportive policies, India's spending on energy imports falls from 5.3% of GDP in 2025 to 3.1% in 2035, and to 1.5% by mid-century. For a country that imports most of its oil and has recently seen crude prices above $100 a barrel, that is a powerful economic case for accelerating the transition.
