Conclusion
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. According to Mercom India, the C&I market is expected to grow at a compound annual rate of 18.8% until 2030, with industrial hubs in Maharashtra, Gujarat, and Karnataka at the forefront of this trend. For firms that have yet to make the transition, the time has never been better.
