Adani Green Energy Ltd (AGEL) plans to invest about ₹15,000 crore to add more than 10 gigawatt-hours (GWh) of battery energy storage capacity in the current financial year, as it pivots towards delivering reliable, dispatchable clean power amid India’s accelerating energy transition.

The proposed addition will be over and above the roughly 3 GWh of installed storage capacity the company expects to reach shortly, following the commissioning of 1.4 GWh during FY26, it said during its earnings call.

The batteries are being developed alongside renewable generation at Khavda in Gujarat, where AGEL is building what it describes as the world’s largest renewable energy park.

The storage systems are aimed at supplying power during peak evening demand, when solar output tapers, helping smooth load profiles and enable round-the-clock renewable energy.

“We are in the process of significantly ramping up our battery capacity additions, which we expect to exceed 10 GWh in this fiscal,” Executive Director Sagar Adani said.

“In FY26, we added 1.4 GWh, and in the next few days, we expect to reach around 3 GWh of installed capacity in Khavda,” he added.

AGEL already has a 19.3 GW operational renewable energy portfolio—the largest in India—and is targeting 50 GW by FY30, according to its post-Q4 earnings investor presentation.

The current capacity mix comprises 70% solar, 13% wind, and 17% hybrid projects.

During FY26, the company generated 38 billion units of electricity, up 34% from 28 billion units in the previous financial year.

On battery storage, the planned 10+ GWh capacity will include about 75% backed by 25-year fixed-tariff power purchase agreements (PPAs), according to the presentation.

AGEL’s expansion into battery storage reflects a broader shift in India’s power sector, where the focus is moving from rapid renewable capacity addition to ensuring grid stability and reliable supply.

India’s grid-scale battery storage ecosystem is still at a nascent stage, with projects in various phases of commissioning and integration despite growing policy support and tender activity.

As renewable penetration rises and electricity demand increases, storage is expected to play a key role in balancing supply and managing peak loads.

By scaling up storage alongside generation, AGEL is positioning itself to deliver firm and flexible clean energy, aligning with the next phase of India’s energy transition.

As India’s clean energy transition accelerates, the spotlight is shifting decisively from capacity addition to system reliability. Solar and wind have scaled at an unprecedented pace; the next phase is about making this power dependable, dispatchable, and aligned with demand.

In this evolving equation, battery energy storage is emerging as a critical enabler, with AGEL at the centre of this transformation.

AGEL’s roadmap to integrate battery storage as a core pillar of its growth strategy reflects a deliberate shift—from viewing storage as a supporting asset to treating it as essential energy infrastructure.
