Enel Green Power, part of the Italy-based power group Enel, has launched construction on another large-scale BESS in Chile. 

Enel Green Power Chile has launched construction on the Finis Terrae battery energy storage system (BESS), it said earlier this week (17 August). It is being integrated with the existing Finis Terrae solar PV park in the northern Antofagasta region. 

The BESS has a power rating of 100MW at the interconnection point and has grid-forming capabilities. This will enable it to provide services to the grid that help maintain stable voltage and frequency on the grid of the National Electric System (NES).

It is the sixth large-scale BESS project from Enel Green Power in Chile that Energy-Storage.news is aware of. The firm says it has a storage capacity of 730MW in the country.

It is also building the BESS Las Salinas (205MW) and Azabache BESS (94MW) projects. Projects that are now in commercial operation meanwhile are the La Cabana BESS (34MW), the Don Humberto BESS (67MW) and the El Manzano BESS (67MW). Enel typically hasn’t revealed the BESS supplier for its projects.

Chile is one of the most active grid-scale markets for storage globally, and by far the regional leader in Latin America. BESS are being deployed to provide stability services to the grid but primarily to support the country’s solar PV fleet which has seen huge curtailment and negative pricing challenges in the last few years. 

Stats came out recently on how much curtailment energy storage has already reduced. BESS durations are typically 4-6-hours in Chile reflecting the solar load shifting applications.

Just this month, developer Limes reached ready-to-build (RTB) stage on a 1GWh project, Verano Energy ordered 660MWh from Sungrow for a project, while ContourGlobal started building a 131MWp solar, 90MW/360MWh BESS project. 

Projects are often commercialised via long-term offtakes with big industrial groups or utilities. 

Such has been the pace of activity, Chile reached its 2027 energy storage deployment target a year early and looks set to reach its 2050 target by 2027.
