India Proposes Storage Mandate for Renewables

India's energy authorities are developing new regulations that would require renewable energy projects to incorporate battery storage. This initiative seeks to improve the management of fluctuating power generation from solar and wind sources.

The proposed mandate, set to commence from July 1, 2027, would apply to all new solar and wind energy projects commissioned after this date. The Central Electricity Authority (CEA) is leading the development of these guidelines.

Under the proposed framework, developers would need to install co-located energy storage systems. These systems are expected to have a capacity equivalent to at least 10% of the renewable project's installed generation capacity.

Furthermore, the energy storage facilities would be required to provide a minimum discharge duration of two hours. This specification aims to ensure a consistent power supply during periods of low renewable generation or high demand.

The objective behind this regulatory move is to mitigate energy curtailment, a situation where generated electricity cannot be absorbed by the grid. By integrating storage, the grid can better balance supply and demand, enhancing overall reliability.

This policy direction reflects a broader strategy to support the expansion of renewable energy while maintaining grid stability. Such measures are crucial for countries aiming to increase their clean energy contributions.

The implementation of these requirements could influence investment decisions and project designs within India's renewable energy sector, promoting further technological integration in the energy landscape.
