AmpereHour Energy and IndiGrid have commissioned a 180 megawatt (MW)/360 megawatt hour (MWh) battery energy storage system (BESS) at the Gujarat Energy Transmission Corporation (GETCO) substation in Gujarat, constituting India’s first large-scale standalone utility-scale battery energy storage project. Gujarat Urja Vikas Nigam Limited will act as the off-taker, and the facility is reported to be the country’s largest standalone BESS installation and among the largest battery storage capacities in Asia. The commissioning comes as Gujarat strengthens its renewable energy ecosystem, with nearly 870 MW of battery storage projects launched across the state.

The installation is intended to strengthen grid stability and to support round-the-clock renewable energy integration by storing excess renewable power during off-peak hours and discharging it during periods of high demand. AmpereHour scaled learnings from an earlier 40 MWh Delhi project to develop the 360 MWh system and carried out advanced simulation studies to optimise the electrical chain from the 220 kilovolt (kV) grid connection to the DC systems. These measures were said to enable higher Round Trip Efficiency (RTE) and increased usable energy.

The facility deploys AmpereHour’s ELINA energy management system to integrate large data streams and uses the AH Suite software platform to support execution across multiple contractors. The company indicated that a scientific engineering approach and a first time right implementation principle facilitated smooth commissioning. Management characterised the project as a lighthouse moment for the Indian energy sector and attributed scale and commercial optimisation to the flexible integration architecture.

IndiGrid, as project developer, characterised the BESS facility as setting a new benchmark for utility-scale energy storage infrastructure in India and as supporting the country’s target of achieving 500 gigawatt (GW) of non-fossil fuel capacity by 2030. The developer highlighted the role of the storage system in advancing India’s energy transition and noted ongoing plans to expand grid-scale storage. The commissioning is expected to inform further deployments and operational practices across the sector.
