Financial feasibility of behind-the-meter solar-plus-storage in India

A new report says solar-plus-energy storage will become an attractive investment option for commercial consumers in India as early as 2023 for electricity bill reduction. For high-tariff paying residential consumers, the system will reach grid parity post-2027. The report findings are based on the levelized cost analysis of solar-plus-energy storage systems for consumers in the Indian State of Tamil Nadu.
