Overview
The Kilokari BESS Private Limited (KBPL) project stands as a landmark in India’s energy transition, representing the nation’s first regulatory-approved, commercial grid-scale Battery Energy Storage System. While many storage projects exist in pilot phases or remote renewable hubs, KBPL is unique for its successful integration into one of the world’s most complex and densely populated urban environments: South Delhi.
Project Profile
Project Name: BSES Rajdhani Power Limited
Commissioning Date: 30th March 2025
Project Location: Kilokri Substation, Delhi
Project Size (in MWs): 21
Regulatory and Financial Innovation
KBPL broke new ground by becoming the first project of its type to receive formal approval from the Delhi Electricity Regulatory Commission (DERC). Developed under a Build, Own, Operate, and Transfer (BOOT) model with a 12-year Battery Energy Storage Service Agreement (BESSA), it demonstrates a viable commercial framework for urban discoms. The project’s success was further bolstered by a unique collaborative ecosystem, involving IndiGrid, AmpereHour Energy, and BRPL, supported by concessional funding from the Global Energy Alliance for People and Planet (GEAPP).
Technical Excellence and Grid Integration
Executing a 20 MW / 40 MWh utility-scale project within a legacy substation in a congested metropolitan area presented extreme logistical hurdles. Despite these challenges, the team achieved commissioning in a record 11 months—ahead of schedule. The system utilizes AmpereHour’s proprietary AI-driven ELINA Energy Management Software, which allows for sophisticated energy arbitrage and real-time management of grid-specific issues like voltage dips and peak load spikes.
Social and Environmental Impact
Beyond technical metrics, the project serves a critical social function. By providing four hours of clean backup power daily, it directly enhances energy security for 100,000 residents and vital infrastructure, including Moolchand and Safdarjung hospitals. It effectively displaces fossil-fuel-based peaking power and reduces reliance on diesel generators, proving that BESS is not just a grid tool, but a tool for public health and urban sustainability.
KBPL is a “first-of-its-kind” proof of concept that battery storage can defer massive capital expenditure in urban infrastructure while accelerating the transition to a carbon-neutral grid.
