Energy storage is now a cornerstone of modern power systems, according to Ayush Misra, Co-Founder and CEO of AmpereHour Energy.
Ayush Misra expressed this view on the successful commissioning of India’s first regulatory-approved grid-scale battery energy storage system (BESS) that AmpereHour Energy commissioned for IndiGrid at the Kilokari substation of BSES Rajdhani Power Ltd (BRPL), in Delhi.
“We are proud to partner with Indigrid and BRPL on this landmark project, demonstrating the scalability and reliability of our technology in urban utility networks. As India accelerates its transition to clean energy, solutions like these are essential in ensuring a resilient, flexible, and future-ready grid,” Misra added in a release issued by AmpereHour Energy.
Four hours of daily power backup
The 20 MW/40 MWh BESS was delivered AmpereHour Energy on a turnkey basis under a long-term Battery Energy storage capacity agreement (BESPA) with BRPL. Installed and commissioned in just 11 months, ahead of schedule, the system became operational in April 2025. The project primarily benefits 100,000 residents of South Delhi, including high-demand areas such as Defence Colony and Lajpat Nagar.
The BESS provides four hours of uninterrupted backup power daily—two hours during afternoon peaks and two at night—helping replace fossil fuel based power generation during peak hours with renewable energy from solar or wind. The system also reduces reliance on diesel gensets and enhances power availability for critical infrastructure including Moolchand and Safdarjung hospitals and key educational institutions.
ELINA software
The system is powered by AmpereHour’s proprietary ELINA Energy Management Software, which enables real-time, AI-driven battery optimization. ELINA manages India-specific grid challenges such as voltage dips and peak spikes, while allowing for intelligent energy shifting based on real-time demand and supply signals. During installation, the project engaged over 70 local workers and technicians, contributing to local job creation and technical skill development in the region.
Financing partner
The project was also supported through concessional financing from the Global Energy Alliance for People and Planet (GEAPP), highlighting the role of public-private collaboration in advancing India’s clean energy goals.
Replicable blueprint
AmpereHour’s partnership model and turnkey approach with BRPL offers a replicable blueprint for urban BESS deployments nationwide, the release said, adding that company’s projects span over 50 sites globally, with around 100 MWh commissioned to date and nearly 1,000 MWh under execution across India, Middle East, Africa and Europe, including large-scale deployments of 180 MW/360 MWh and 250 MW/ 500 MWh in India.
