AES Andes Focuses on Renewables and Discontinues Green Hydrogen Development

January 23, 2026

AES Andes has announced that, following a detailed review of its project portfolio, it has decided to desist from the execution of the INNA project, an initiative designed to produce green hydrogen and green ammonia.

While the INNA project is fully compatible with other activities in the region, AES Andes has chosen to focus its efforts on the development and construction of its renewable energy and energy storage portfolio, in line with the guidelines of its parent company in the United States. The company emphasized that this decision does not call into question the value or potential of Chile’s green hydrogen industry.

Since the launch of its Greentegra strategy, AES has added a total of 2,181 MW of renewable generation and battery storage to its portfolio across Chile. This has allowed the company to transform its energy mix, which is now 70% renewable.

Currently, the company’s focus is on the commissioning of the Andes Solar III and Bolero BESS plants to achieve commercial operation in the first half of this year. Simultaneously, construction continues on four new renewable projects: Arenales, Cristales, Pampas, and Atacama BESS.

Together, these projects will add 2,363 MW to the portfolio. This means that by 2027, AES Andes will have completed renewable growth exceeding 4,500 MW, investing over US$4 billion in the country since the launch of Greentegra — reaffirming its position as a regional leader in the energy transition.

Through these actions, AES Andes continues to contribute actively to Chile’s energy transition while providing security, competitiveness, and sustainability to the national electric system.

Consistent with its vision from the start, AES in Chile will continue to evaluate new technologies and innovative solutions that align with market conditions, long-term value creation, and the company’s strategic objectives. This work will continue in close collaboration with all stakeholders and sector authorities.

About AES Andes
AES Andes generates and sells energy in Chile, Colombia, and Argentina. The company operates 5,375 MW in South America and maintains an extensive portfolio of renewable energy projects under development. It is one of the region’s leading power generation firms, with a diversified portfolio including hydroelectric, wind, solar, energy storage, natural gas, and coal-fired plants.

Since the 2018 launch of its transformational Greentegra strategy, AES Andes has made substantial progress in reducing the emissions intensity of its portfolio. Investments exceeding US$2.3 billion have enabled the incorporation of 2,290 MW of wind, solar, and battery capacity.

In Chile, AES and its subsidiaries own and operate 3,603 MW, consisting of 1,108 MW thermal, 771 MW hydroelectric, 435 MW wind, 838 MW solar PV and 451 MW battery energy storage systems (BESS). The company also operates seawater desalination plants and transmission lines. Currently, it has 2,363 MW of renewable capacity under construction, alongside a project pipeline of 4,131 MW that have either obtained Environmental Qualification Resolutions (RCA) or are currently undergoing environmental licensing.

Additionally, the company owns InterAndes, a 409-kilometer, 345 kV transmission line connecting the Andes substation in Chile to the Cobos substation in Argentina. Authorized in 2022 for bidirectional energy exchange based on economic opportunity, this line represents a significant milestone in regional energy integration and enhances the security and sufficiency of both national grids.
