The Mejillones AES Angamos BESS is a 20,000kW energy storage project located in Mejillones, Antofagasta, Chile.
The electro-chemical battery energy storage project uses lithium-ion as its storage technology. The project was commissioned in 2012.
The Mejillones AES Angamos BESS was developed by AES Energy Storage. The project is owned by AES Gener (100%), a subsidiary of The AES.
The key applications of the project are electric supply reserve capacity – spinning and frequency regulation.
A123 Systems, AES Energy Storage and AES Gener have delivered the battery energy storage project.
This project will utilize 20 MW of A123 lithium-ion batteries to supply a flexible and scalable emissions-free reserve capacity installation for AES Gener.
The energy storage system is capable of providing up to 20 MW of power nearly instantaneously. This output is designed to be maintained for 15 minutes at full power.
