AES to give Chilean power plant 20MW battery storage

AES Energy Storage and AES Gener, the company’s Chilean subsidiary will integrate 20MW of advanced battery-based energy storage with a 544MW thermal power plant in the North of the country.

The project will allow the plant to generate an additional, productivity-enhancing 20MW of power at virtually all times, without sacrificing grid flexibility or reliability, says the company.

This increase of around 4% represents the energy that would otherwise be slide-lined for use in the event of an unexpected transmission failure.

AES Gener is the country’s second largest power generator, and has already constructed a 12MW energy storage system for its Norgener power plant, some 170 kilometers from Antofagasta.

The Los Andes Battery Energy Storage System (BESS) has been delivering a similar reliability service since 2009, and comprises of approximately one million advanced lithium-ion battery cells, divided between ten 2MW battery containers, and five 4MW power controls containers.
