India’s ambitious clean energy transition demands a parallel development in energy storage infrastructure, with Standalone Energy Storage Systems (Standalone ESS) emerging as a key enabler. As the country rapidly scales up variable renewable energy (VRE), Standalone ESS offers a dispatchable solution to address the intermittency of renewables, support grid stability, and optimise energy usage.
Unlike VRE-paired ESS, which is typically owned or contracted by renewable energy developers to store and dispatch power to smoothen renewable integration, Standalone ESS functions as an independent asset. Utilities, grid operators or third-party entities can own and deploy it flexibly to provide grid balancing, peak shaving and ancillary services, enabling storage to operate based on grid requirements rather than generator constraints. Additionally, emerging business models such as Energy Storage as a Service (ESaaS) offer storage as a…
