Adani Green Becomes First Indian Renewable Energy Company to Cross 20 GW Operational Capacity

Adani Green Energy Limited (AGEL) has crossed 20 gigawatts (GW) of operational renewable energy capacity, becoming the first renewable energy company in India to achieve the milestone primarily through greenfield project development.

The company said its operational portfolio now generates more than 52 billion units of clean electricity annually, accounting for nearly 3% of India’s total electricity consumption. According to AGEL, the annual generation is sufficient to power more than 9 million households and is comparable to the yearly electricity consumption of New York City or nearly the combined demand of Mumbai and New Delhi.

The renewable energy generation is also expected to offset more than 37 million tonnes of carbon emissions each year, equivalent to the carbon sequestration capacity of approximately 1.77 billion trees or removing around 8.1 million passenger vehicles from the roads.

The achievement comes nearly a decade after AGEL commissioned its first renewable energy project at Kamuthi, Tamil Nadu, in 2016. During FY2025-26, the company added 5,051 MW of renewable energy capacity, which it said is the highest annual renewable capacity addition by any company outside China.

Commenting on the milestone, Sagar Adani, Executive Director of AGEL, said:

“Surpassing 20 GW demonstrates what disciplined execution and long-term vision can achieve. Today, AGEL, along with our efficient team and longstanding partners, delivers renewable electricity almost equivalent to annual power requirement of Mumbai and New Delhi combined, reinforcing the country’s energy security while accelerating its clean energy transition.”

The milestone follows Sagar Adani’s address at the inaugural Adani Green Energy Dialogue, held during London Climate Action Week on June 26 at the Science Museum in London, where he highlighted the need to accelerate electrification through renewable energy integrated with large-scale battery storage to enhance energy security, affordability and round-the-clock clean power supply.

AGEL’s current operational portfolio includes approximately 14.2 GW of solar, 2.7 GW of wind, and 3.3 GW of wind-solar hybrid capacity. The company has also commissioned 3.55 GWh of Battery Energy Storage Systems (BESS), which it described as the world’s largest deployment outside China and among the fastest implemented globally.

Sagar Adani added that battery energy storage will play a critical role as renewable energy contributes a larger share of India’s electricity mix. AGEL plans to add 10 GWh of battery storage during FY2026-27 and expand its storage portfolio to 50 GWh over the next five years in support of its target of achieving 50 GW of renewable energy capacity by 2030.

The company’s flagship growth project remains the 30 GW renewable energy park at Khavda in Kutch, Gujarat, regarded as the world’s largest renewable energy project under development. Spread across 538 square kilometres, the project covers an area nearly five times the size of Paris. AGEL has already commissioned 9.5 GW of solar capacity at the site, representing more than 30% of the project’s planned capacity.
