Key Messages

In early September, India's peak daytime electricity demand stood at 241 GW, a record high. The solar market in India plays a crucial role in meeting this ever-increasing demand, especially the rooftop photovoltaic sector which has enormous untapped potential. The Government of India aims to have 40 GW of rooftop photovoltaics (RTPV) installed capacity by March 2026.

However, high penetration of variable renewable energy (RE) sources at the end-user level will pose challenges such as mismatched supply and demand and grid stability/flexibility, leading to grid stability and outages. Using an energy storage system (ESS) alongside RTPV could help overcome these issues in the electricity system.

The distributed solar and behind-the-meter (BTM) energy storage system linked to a utility's distribution network can meet a consumers energy needs, act as a backup during grid failures, reduce electricity bills, and provide grid services to distribution companies (DISCOMs).
