Adani Green Energy Limited added five gigawatts (GW), equal to 5,051 megawatts (MW), in the financial year 2025–26, taking its total operational portfolio to 19.3 GW. This annual greenfield capacity addition is the highest by any company globally outside China and reinforces the firm's leadership in India's renewable sector. The company framed the achievement as a pivotal step in accelerating the country's transition to a low-carbon economy and strengthening energy security.

The new capacity comprised three point four GW (3,409 MW) of solar, zero point seven GW (686 MW) of wind and one GW (956 MW) of wind-solar hybrid installations. The additions are expected to offset around 10 million tonnes of carbon emissions annually, and the company's 19.3 GW portfolio will deliver an annual carbon offset of 36 million tonnes. The firm said the result demonstrated that ultra large-scale renewable deployment is executable at pace.

Most of the additional capacity was commissioned at the Khavda site in Gujarat, described by the company as the world's largest single-location renewable energy plant and built across 538 square kilometres, an area five times the size of Paris. Out of the planned 30 GW at Khavda by 2029, the firm has already installed cumulative capacity of nine point four GW (9,413 MW) on the site. The project also brought online an initial 1,376 megawatt hours (MWh) of battery energy storage within eight months of starting work, supporting grid stability and renewable integration.

The Khavda deployment uses bifacial solar modules and solar trackers, employs five point two MW wind turbines and deploys waterless robotic cleaning systems to minimise water use while improving operational efficiency. The company noted continued focus on reducing the levelised cost of energy and on scaling storage solutions as it pursues a target of 50 GW by 2030. The firm also cited third-party recognition, including a top ranking in the Global Top 100 Green Utilities list for 2025 and being named India's leading sustainability performer in the power sector for a second consecutive year.
