AES Andes, a subsidiary of the US energy company AES Corporation, has filed an environmental impact assessment (EIA) for the Pampas Hybrid Park project, which will be located in Taltal, in the Antofagasta region of northern Chile, and will consist of a wind and a solar plant with a total capacity of 392 MW. The wind park will have an installed capacity of 140 MW, while the photovoltaic plant will be distributed across two zones and will total 252 MW. The project will be connected to Chile’s National Electric System through the Pampas Parinas high voltage line. Construction of the project is expected to begin in 2024. The project will also comprise Battery Energy Storage System (BESS), that should supply 624 MW for up to 5 hours. The installation of a battery system will allow energy to be stored in the hours of greatest generation and to be transferred during periods of greater consumption.
At the end of 2021, wind represented about 10% of the country’s installed capacity with 3.1 GW and 8% of its power generation with 7.3 TWh, while solar represented 15% of Chile's installed capacity with 4.7 GW and about 13% of its power generation with 11.2 TWh.
