Cochrane Thermal Power – Lithium Ion Battery Energy Storage System, Chile

By Carmen

The Cochrane Thermal Power – Lithium Ion Battery Energy Storage System 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 announced in 2012 and was commissioned in 2016.

Description

The Cochrane Thermal Power – Lithium Ion Battery Energy Storage System was developed by AES Energy Storage and AES Gener. The project is owned by Mitsubishi (40%) and AES Gener (60%), a subsidiary of The AES.

The key applications of the project are electric supply capacity and electric energy time shift.

Contractors involved

AES Energy Storage, AES Gener, GS Yuasa, Lithium Energy Japan and Mitsubishi have delivered the battery energy storage project.

Additional information

The Cochrane thermo project calls for the construction and operation of a coal-fired thermoelectric plant in the bay of Mejillones. Developed by Empresa Eléctrica Cochrane, a 60-40 JV between Inversiones Nueva Ventanas (subsidiary of AES Gener), and Diamond Pacific Investment (subsidiary of Mitsubishi Corp), the plant will feature two generation units, a substation and a 153km transmission line (220kV) that will inject power to the country’s northern SING grid. The energy generated will be sold at a fixed price to mining companies including SQM and Sierra Gorda.
