AmpereHour Commissions First Grid-Scale BESS For Indigrid In Delhi

AmpereHour Energy, a full-stack energy storage solutions provider, in partnership with Indigrid through their consortium Kirlokari BESS, has commissioned a battery energy storage system (BESS). This project was developed in collaboration with BSES Rajdhani Power Limited (BRPL) in Delhi. This deployment represents one of the first regulatory-approved BESS projects in India, signaling an advancement in urban grid modernization and reliable clean energy delivery.

BESS Project

The 20 MW / 40 MWh Battery Energy Storage System was delivered 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.

The project can play a key role in peak load shaving, capex deferral, energy arbitrage savings, and ancillary services provision, reducing power purchase costs and bolstering grid resilience and has the potential to offset about 65 Tons of CO2 every day through it’s 80 MWh of daily discharge.

“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 said, “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 the utmost levels of safety.”

About The Company

AmpereHour Energy, founded in 2017 by IIT Bombay alumni and power sector veterans Ayush Misra, Rahul Shelke, Harshal Thakur, and Neehar Jathar, has built a strong track record in delivering modular, scalable, and software-led BESS solutions. The company’s projects span over 50 sites globally, with ~100 MWh commissioned to date and nearly 1000 MWh under execution across India, the Middle East, Africa, and Europe, including large-scale deployments of 180 MW/360 MWh and 250 MWh/ 500 MWh in India.

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.

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. During installation, the project engaged over 70 local workers and technicians, contributing to local job creation and technical skill development in the region. With increasing renewable penetration and EV adoption, battery energy storage is vital to India’s grid transformation. AmpereHour’s partnership model and turnkey approach with BRPL offer a replicable blueprint for urban BESS deployments nationwide.
