Engie turns on Latin America’s largest storage battery

Engie Chile, the French energy major Engie’s subsidiary in Chile, announced that the building of a 139 MW/638 MWh battery is complete.

It asserted that it is Latin America’s largest deployed energy storage system.

The storage facility is connected to the 181.2 MW Coya PV project, located in Maira Elena, in the Antofagasta region of northern Chile, which has some of the greatest solar radiation levels on the planet.

In December 2022, Engie made the project announcement.

The solar plant’s 58 inverters are equally spaced among the 232 containers that make up the facility.

It is the same as delivering 200 GWh annually on average.

“After the entry into commercial operation of BESS Coya, we now have 640 MWh of storage capacity in the country,” said Juan Villavicencio, managing director renewables for Engie Chile.

“We will add two more projects that are currently under construction: BESS Tamaya (68 MW/418 MWh) and BESS Capricornio (48 MW/264 MWh).

That will translate into around 255 MW of power for 5 hours of energy discharge mainly at night.”

Batteries for the project were supplied by Sungrow, a Chinese firm.

The company’s PowerTitan liquid cooling energy storage technology serves as the foundation for the storage systems.

In April 2023, the Coya solar project went into service.

At the moment, Engie has a second storage facility in Arica, Chile.

The 2 MWh system was put into service in 2019 and is powered by lithium-ion batteries.
