India's coal-based power plants are struggling to ramp down during midday solar surges, leading to renewable energy curtailment. Ember's analysis shows that around 10 GWh of battery storage is needed to absorb surplus energy and prevent curtailment. The lack of flexibility in the grid, with coal providing most of the reserves, is causing renewable curtailment to accommodate coal plants operating at their minimum technical loads. Without sufficient storage and flexibility, curtailment of clean electricity will continue to rise as solar capacity grows in India. The article discusses the increasing curtailment of solar and wind energy in India due to the lack of storage solutions, highlighting the need for battery storage projects to absorb surplus generation and provide downward reserves. It recommends allowing grid charging during solar surplus hours to reduce curtailment, lower system stress, and improve flexibility, emphasizing the importance of correcting the current framework to unlock the next phase of India's renewable energy growth. The Khavda project in Gujarat is cited as a successful and quick deployment model for battery storage projects.
