AES Gener begins work on largest battery storage facility in Latin America

Energy Storage News:

AES Gener has held a virtual groundbreaking ceremony to mark the start of construction on a 112MW / 560MWh battery energy storage system project in Chile, Latin America.

Multinational electric power generation and distribution company AES Corporation’s local subsidiary said the system, which can store power from nearby solar and wind facilities for up to five hours, is the biggest battery storage system in Latin America to date as well as being Chile’s first solar-plus-storage project.

The batteries will be paired with 253MW of renewable energy generation, including the 180MW Andes Solar II B project in Antofagasta. Andes Solar II B will be built with 10MW of modular, prefabricated solar PV panels and 170MW of bifacial solar PV panels of the type AES Gener has already deployed in the 80MW Andes Solar II A project which has already begun construction.

The solar energy to be integrated into the national electricity system with the batteries will be built on mountain ranges in Antofagasta in the Atacama Desert, enjoying a combination of high solar irradiance at relatively low temperatures. Meanwhile, the output of the 73MW Campo Lindo wind farm being built in the Bío Bío region in the central south of Chile will also be integrated using the storage system. Campo Lindo is the first phase of a total 480MW cluster of wind turbines being built in the region, near the city of Los Ángeles.

Battery systems used will be supplied by Fluence, the energy storage technology provider co-owned by AES Corporation and engineering solutions company Siemens. Fluence said that its Sunstack modular battery storage solutions will be used – part of the company’s sixth generation range of energy storage systems launched earlier this year. AES Gener said the ability to store energy for five hours – and therefore charge the batteries for dispatch after the sun has set – will make the company’s energy supply “more competitive and resilient”.

AES Gener also said that the new solar-wind-storage build-out, along with 709MW of energy projects that it has already begun building in Chile, the company is contributing to the creation of around 6,000 direct jobs in the country. In total, AES Gener is adding 2,300MW+ of renewable capacities and batteries to its portfolio in Chile by 2024 under its existing plans, the company said in a press release.
