AmpereHour And IndiGrid Commission India’s Largest Standalone BESS

22 May 2026 CW Team

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.

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.

Beyond Backup Power

For decades, diesel gensets occupied a largely functional role in buildings: a mandatory backup system specified to meet statutory requirements and activated only during grid outages. Today, however, this perception is undergoing a profound shift. Across residential, commercial and mission-critical developments, developers, consultants and operators are increasingly viewing gensets as integral to a broader energy resilience strategy. Rising occupant expectations, growing dependence on digital systems and the proliferation of smart technologies mean that uninterrupted power has become essential..

Mumbai-Pune Connecting Link is designed to ensure reliable all-weather, high-speed transport.

Infrastructure connectivity will be one of the keys to achieve Viksit Bharat. And the Mumbai-Pune Connecting Link has been developed as a long-term infrastructure solution for Western India. Dr Anilkumar Gaikwad, Vice Chairman & Managing Director, Maharashtra State Road Development Corporation (MSRDC), a speaker at the RAHSTA Expo 2026, elaborates upon the project and its significance.The Mumbai-Pune Connecting Link has largely been discussed as a travel-time reduction project. From MSRDC’s perspective, what larger infrastructure and mobility problem was this project actually designed to..

Noida International Airport

Noida International Airport (NIA) is not just another capacity addition to India’s aviation map. It is a test case in whether India can build airport infrastructure that is scalable from Day 1, operationally efficient at launch, and resilient enough to grow without the familiar pain points of brownfield expansion.Its significance lies not merely in the first phase but in the way the airport has been planned for its fourth. Scheduled to begin commercial operations on 15 June 2026, NIA’s first phase comprises one runway and one passenger terminal designed to handle 12 million passengers annu..
