India ranked as the world’s second-largest market for annual solar and wind capacity additions in 2025, behind China, according to BloombergNEF’s India Transition Factbook 2026, published on October 13. The report, commissioned by Bloomberg Philanthropies, identifies India’s rising electricity demand and falling renewable equipment prices as factors supporting further solar expansion. It also highlights a major challenge: sustaining deployment will require substantial investment in generation and the infrastructure needed to integrate additional clean power.
The investment requirement is considerable. BloombergNEF estimates that India’s solar and wind sectors will need between $123 billion and $163 billion in capital through 2030, expressed in real 2025 dollars. The estimate underlines the scale of financing needed to maintain renewable capacity growth as electricity consumption increases. India attracted $72 billion in energy-transition investment in 2025, equivalent to approximately 1.7% of its gross domestic product, placing it fifth globally for such investment, according to the report.
India’s recent installation figures provide context for its international standing. The Ministry of New and Renewable Energy reported that the country added approximately 44.61 GW of solar capacity and 6.06 GW of wind capacity during the 2025-26 financial year. By September 30, 2026, cumulative installed solar capacity had reached 171.05 GW, while wind capacity stood at 59.20 GW. These official figures cover the financial year rather than the calendar year used for BloombergNEF’s 2025 market ranking, so the two datasets should not be treated as identical measures.
The transition is also beginning to influence India’s overall electricity mix. BloombergNEF reports that non-fossil technologies accounted for 80% of the new power-generation capacity added to the grid over the preceding decade. These sources supplied one-third of India’s electricity demand during the first seven months of 2026. Coal nevertheless continued to provide the majority of the country’s electricity, showing that faster renewable deployment has not yet removed the system’s dependence on conventional generation.
Transmission infrastructure will be central to converting installed renewable capacity into dependable electricity supply. India plans to develop transmission infrastructure capable of connecting 336 GW of renewable energy capacity by the first quarter of 2032, according to BloombergNEF. This requirement reflects the geographical challenge of moving electricity from renewable-rich regions to major consumption centres, alongside the need to manage variations in wind and solar generation.
The report also identifies energy security as an important economic driver. India’s growing energy demand and reliance on imported oil create incentives to expand domestic renewable generation and reduce exposure to imported fuels. BloombergNEF’s assessment suggests that clean-energy deployment is increasingly linked to both decarbonisation and the country’s longer-term energy security.
India’s second-place ranking therefore reflects substantial progress in adding renewable capacity, but maintaining that position will depend on more than new installations. The investment pipeline, transmission expansion and integration of variable renewable power will determine how effectively the country converts its deployment momentum into a more resilient electricity system.
