Large scale deployment of intermittent renewable power requires storage solutions to address imbalances between supply and demand, and more ancillary services. Battery energy storage systems (BESS) are gaining popularity worldwide but their near-term deployment potential in India is limited by several challenges. Pumped storage projects (PSPs) have emerged as preferred market solution.
