ENGIE Announces Construction of a Storage System of More than 630 MWh at the Coya PV Solar Plant

True to its purpose of acting to accelerate the transition towards a carbon-neutral economy, ENGIE Energía Chile SA (EECL) announced the construction of one of the largest battery-based energy storage system projects in Latin America, which will It will be located within the PV Coya Solar Plant in the María Elena commune, Antofagasta region.

The project will have a storage capacity of 638 MWh, and will have Battery Energy Storage System (BESS) technology using lithium batteries from the company Sungrow Power Supply. These will store renewable energy from the PV Coya Photovoltaic Park, providing greater efficiency to the system and allowing this energy to be supplied for 5 hours, which translates into a delivery of 200 GWh on average per year.

BESS Coya will allow around 100,000 homes to be supplied with green energy. In this way, it will avoid emitting 65,642 tons of CO2 per year, equivalent to removing about 22,000 internal combustion vehicles from circulation.

“ At ENGIE we continue to make progress in our decarbonization plan. The BESS Coya project will allow clean solar energy to be delivered to the grid at night, increasing the flexibility of dispatching the Solar Plants to the National Electric System, making it more efficient and providing greater security of supply ”, explained Rosaline Corinthien, CEO of ENGIE Chile.

“ We are proud to partner with ENGIE to offer our advanced liquid-cooled energy storage system, the PowerTitan, which makes it easy for our customers to store energy in a more efficient and long-lasting way. We appreciate the continued trust of ENGIE, this is already our fourth project together with them in Chile. As one of the first entrants in the Chilean solar and storage market, Sungrow offers competitive products and services backed by a dedicated local team that includes sales, technical support and after-sales services ,” stated Ada Li, Director of Sungrow Latin America.

The start of construction is scheduled for this month and it is expected to have 100% of the batteries energized in the first quarter of 2024. It should be remembered that the energization of the entire PV Coya Solar Plant ended on October 28 and already has with the availability of 181.25 MWac as nominal power.

“ BESS Coya ” is the second initiative that ENGIE has developed in this type of technology. The first is located in Arica and consists of a lithium-ion battery system with a storage capacity of 2MW/h.
