AES Andes submits the Pampas Hybrid Project for environmental review

February 21, 2023

• The initiative consists of solar and wind power generation, with an installed capacity of up to 392 MW, as well as battery storage that can provide 624 MW of power for five hours.

February 21, 2023 - AES Andes has submitted an initiative that combines different sources of 100% renewable energy for environmental review, in a new step in the transformation of its energy matrix.

We are talking about the Pampas Hybrid Park project, located in Taltal, Antofagasta region, which consists of a wind and solar power plant with a total installed capacity of 392 MW, together with a Battery Energy Storage System (BESS) that can provide 624 MW for up to 5 hours.

The wind farm will have an installed capacity of 140 MW, while the photovoltaic plant will have two zones with a total capacity of 252 MW.

The project will be connected to the National Electric System through the Pampas Parinas high voltage line.

Pampas intends to capitalize on the high wind and photovoltaic potential of an area known for its significant wind component, which is complemented by favorable solar availability.

In addition, the installation of batteries will make it possible to store energy during peak generation periods and transfer this generation to peak consumption periods, such as at night.

The initiative was launched on February 17 with an Environmental Impact Assessment (EIA) and construction is expected to begin in 2024. In addition, it takes into account a peak employment of 904 people during the course of construction.

Javier Dib, CEO of AES Andes, said, "We are very proud to submit a very innovative project that combines three 100% renewable technologies for environmental review. This is a new important step in our Greentegra strategy and confirms our company's commitment to the decarbonization process that the country is going through".

The CEO stated that the Company has started public involvement activities to inform the community in the area of influence about the project and to make the environmental process more viable.
