Adani Green Energy has expanded its operational battery energy storage system capacity to 6.63 GWh, giving it more than half of India’s current operational BESS capacity and taking the company close to 70% of its FY27 target.
New Delhi, Oct 1 — Adani Green Energy Ltd (AGEL) has expanded its operational Battery Energy Storage System capacity to 6.63 GWh, marking a major expansion of its energy storage portfolio.
The company said the capacity can store enough clean energy to power around two million homes for a day. The 6.63 GWh storage capacity is also sufficient to support peak electricity demand in cities such as Nagpur, Patna or Visakhapatnam for several hours.
With the latest expansion, AGEL now accounts for more than 50% of India’s operational BESS capacity, which the company estimates at around 12.6 GWh.
The company said it achieved the 6.63 GWh milestone within 14 months of starting on-site BESS construction at Khavda. As of June 2026, AGEL had 3.55 GWh of operational battery storage capacity.
AGEL is targeting more than 10 GWh of BESS capacity during FY2026-27 and aims to build 50 GWh of storage capacity over the next five years.
The battery systems use lithium-ion technology integrated with energy management systems and automated telemetry to manage charging and discharging, optimise system performance and provide grid services.
Battery storage can help improve grid stability, manage peak electricity demand, reduce renewable energy curtailment and make clean power available when required.
The latest operational capacity is integrated with AGEL’s renewable energy development at Khavda, where the company is developing a 30 GW renewable energy plant spread across 538 square kilometres of barren land.
Sagar Adani, Executive Director at Adani Green Energy, said reaching 6.63 GWh of operational battery storage within 14 months is an important milestone for the company and India’s clean-energy transition. He said the company plans to continue expanding both battery and pumped-storage solutions as electricity demand rises.
