AES seeks approval for 4 GWh collocated battery in Chile

The project located in the Tarapacá region comes with a price tag of $990 million dollars and integrates a massive solar farm with a 809.22 MW five-hour battery energy storage system.

Energy company AES has submitted its Oriente Solar Photovoltaic Park project for environmental assessment in Chile’s Tarapacá region.

The project consisting of a photovoltaic park with a peak power capacity of 581.46 MW. It also includes a battery storage system of up to 809.22 MW, with a storage capacity a maximum of five hours. The energy generated will be injected into Chile’s National Electric System via two parallel transmission lines, each approximately 3 kilometers long, which will be constructed as part of the project.

Specifically, the electrical energy generated in the photovoltaic park and stored in the BESS system will be transported at medium voltage through underground pipelines installed parallel and perpendicular to the park’s internal roads to the SE Solar Oriente, from where it will be evacuated through the project’s high voltage line to the 2×220 kV Lagunas – Puquios sectioning.

The project involves an investment of $990 million.

AES Andes recently obtained environmental approval for the Pampas wind-solar plus storage project in the Antofagasta region, which proposes a wind farm with an installed capacity of 140 MW and a 252 MW photovoltaic park, and a battery-based energy storage system with a capacity of 624 MW with a duration of up to five hours.

The energy company is also proposing the Altos del Sol project also in the Antofagasta region, which is currently under evaluation and includes a 763.6 MW photovoltaic park with a 1,063.4 MW battery storage facility.

This same year, AES obtained environmental approval for the Cristales project, with 340 MW of photovoltaic energy and storage of 542 MW for five hours, also in Antofagasta.
