In a major leap toward sustainable urban energy infrastructure, AmpereHour Energy, in partnership with Indigrid and BSES Rajdhani Power Limited (BRPL), has successfully commissioned India’s first regulatory-approved grid-scale Battery Energy Storage System (BESS) at the Kirlokri substation in South Delhi. Developed under the consortium Kirlokari BESS Pvt Ltd, the project is the first of its kind in India to receive regulatory clearance, marking a significant milestone in the nation’s energy transition efforts.
The advanced 20 MW/40 MWh BESS was commissioned in just 11 months, ahead of schedule, and became fully operational in April 2025. Designed to provide four hours of clean backup power daily—two during the afternoon peak and two at night—the system is expected to benefit approximately 100,000 residents in areas like Defence Colony and Lajpat Nagar. It aims to displace fossil fuel-based power during peak hours with renewable sources like solar and wind, thereby reducing reliance on diesel generators and improving energy access for critical infrastructure including Moolchand and Safdarjung hospitals.
The project integrates AmpereHour’s proprietary AI-driven ELINA Energy Management Software to optimize battery performance and manage grid-specific challenges such as voltage dips and peak load spikes. It also promises to cut power purchase costs through energy arbitrage and defer capital expenditure by managing peak loads effectively.
“Energy storage is now a cornerstone of modern power systems,” said Ayush Misra, Co-Founder and CEO of AmpereHour Energy. “We’re 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.”
Umang Maheshwari, Managing Director BESS, GEAPP, echoed the sentiment, stating: “This project marks a decisive step toward grid modernization and higher levels of renewable integration in the energy mix. We anticipate improved voltage quality, enhanced grid security and enabling us to lower our power purchase cost. I would like to applaud the AmpereHour Energy team for completing the project within the stipulated time at such a demographically challenging site with utmost levels of safety.”
The initiative was supported by concessional financing from the Global Energy Alliance for People and Planet (GEAPP) and generated employment for over 70 local workers and technicians during installation, contributing to local economic development.
AmpereHour Energy, founded by IIT Bombay alumni and power sector veterans, has commissioned ~100 MWh globally and is executing nearly 1000 MWh across India, the Middle East, Africa, and Europe. Their modular, scalable, and software-led BESS solutions have positioned them as leaders in India’s clean energy ecosystem.
