The Commercial & Industrial (C&I) renewable energy market in India has been one of the most rapidly evolving areas of the country’s energy sector. According to JMK Research & Analytics, the cumulative renewable capacity for direct C&I procurement as of end-FY 2024 was 18.7 GW, a whopping 90.4% increase from the previous year. The solar open access market alone reached 21.5 GW by March 2025.
According to Mercom India Research, the C&I renewable energy market has seen a near doubling in the past two years, thanks to declining tariffs, the adoption of state-level policies, and the increasing need for corporate sustainability.

The C&I renewable energy sector in India is at a critical juncture. With the cumulative installed capacity for direct C&I procurement already exceeding 18.7 GW and a year-over-year growth rate of close to 90% (JMK Research), the firms mentioned above are helping to redefine the way India Inc. buys its electricity.
As India advances towards its goal of achieving 500 GW of non-fossil capacity by 2030, the C&I buyer will continue to play an integral role in meeting this demand.
