India Plans Battery Storage Pilots at Coal Plants to Balance Growing Solar Grid

India is initiating pilot projects to install battery storage systems at coal power plants to address the challenge of integrating increasing solar power capacity while maintaining reliable electricity supply. Thermal plants must reduce output during peak solar generation but remain ready to meet evening demand, a balance that battery storage can help achieve by capturing excess solar energy and dispatching it later. The Central Electricity Authority (CEA) and coal generator NTPC are leading these efforts, including a tender for 1.7 GW of battery storage across 11 coal plants. Despite the push for battery storage, India is also prioritizing large-scale pumped hydro storage projects, which are seen as more cost-effective and viable long-term solutions, although batteries offer flexibility and site independence. The government aims to expand non-fossil fuel capacity to 500 GW by 2030, while also increasing coal capacity to ensure round-the-clock power. These initiatives reflect India's strategy to balance renewable expansion with energy security and grid stability.
