Adani Green Energy expands operational battery storage capacity to 6.63 GWh

Adani Green Energy Ltd (AGEL), India’s largest renewable energy company, has expanded its operational battery energy storage system (BESS) capacity to 6.63 gigawatt-hours (GWh) at Khavda, Gujarat, from 3.55 GWh in June 2026. The company said it now accounts for more than 50% of India’s operational BESS capacity of about 12.6 GWh.

“This milestone consolidates Khavda’s position as the world’s largest operational battery energy storage installation at a single location, with 6.63 GWh of operational capacity,” stated AGEL.

AGEL said it achieved the 6.63 GWh milestone within 14 months of commencing on-site BESS construction at Khavda, Gujarat, with this latest capacity addition being commissioned in just 10 months from the start of its construction.

The BESS is integrated with AGEL’s renewable energy (RE) development at Khavda, where the company is developing a 30 GW RE plant across 538 square kilometers of barren land. 

According to AGEL, its 6.63 GWh BESS can store enough clean energy to power around two million homes a day, and support peak electricity demand of cities like Nagpur, Patna or Vizag for several hours. This BESS capacity at Khavda is equivalent to battery storage capacity of more than 150,000 mid-sized EVs and can store enough energy daily to meet almost twice the Delhi Metro’s estimated daily electricity requirement.

“Reaching 6.63 GWh of operational battery storage in just 14 months is a significant milestone for AGEL and India’s clean energy transition. At this scale, storage can make renewable power firmer, more reliable and dispatchable when the grid needs it,” said Sagar Adani, Executive Director, Adani Green Energy Ltd.

The BESS uses lithium-ion battery technology, integrated with an energy management systems (EMS) and automated telemetry to manage charging and discharging, optimise system performance and support grid services.

AGEL said it is on track to add over 10 GWh of BESS capacity in FY 2026-27 and is targeting 50 GWh of storage capacity over the next five years. The company is also pursuing pumped storage projects (PSPs) as part of its broader strategy to build large-scale, firm and dispatchable renewable power capacity.

AGEL develops, owns, and operates utility-scale grid-connected solar, wind, hybrid and energy storage solutions. It currently has an operating renewable portfolio of 20.76 GW and 6.63 GWh of battery energy storage, the largest in India, spread across 12 states. The company has set a target of achieving 50 GW by 2030 aligned to India’s decarbonization goals.
