Adani Green Energy Ltd has announced a major investment of around ₹15,000 crore to build large-scale battery storage systems in India, aiming to make renewable energy more reliable and available throughout the day.
The company plans to add over 10 gigawatt-hours (GWh) of battery storage capacity by FY27. This technology stores excess electricity generated from solar and wind power and releases it when demand is high or when generation drops, such as in the evening.
This move is intended to address one of the biggest challenges of renewable energy, its inconsistency. Solar and wind power depend on weather conditions, which means supply can fluctuate. Battery storage helps smooth out these variations and ensures a steady flow of electricity to the grid.
Adani Green said the new storage capacity will be developed in phases and will build on its existing pipeline, including around 1.4 GWh expected to be operational in FY26 and nearly 3 GWh of additional capacity coming online soon.
A significant part of the project will be located in Khavda, Gujarat, where the company is developing one of the world’s largest renewable energy parks. The battery systems there will work alongside large solar and wind installations to improve grid stability and supply reliability.
The company explained that the goal is to deliver “dispatchable clean energy,” meaning renewable power that can be supplied on demand, similar to conventional thermal power plants.
Adani Green currently operates about 19.3 GW of renewable energy capacity and is working toward a long-term target of 50 GW by 2030. The addition of battery storage is seen as a key step in achieving that goal.
