Greek renewables developer Metlen Energy & Metals has signed an agreement with utility Copec for the sale of the Tamarico II solar-plus-storage project in Chile’s Atacama region.
Announced 10 September, the agreement was signed with Copec S.A. through its subsidiary Copec Flux S.p.A. for the project, which combines 165MW of solar PV generation with 725MWh battery energy storage system (BESS), extendable to 925MWh.
Metlen claimed the sale Tamrico II reaffirms its ability to develop, build and operate its own renewable energy projects, and ultimately monetise their value through its Asset Rotation model.
Metlen also stated that the agreement further strengthens its partnership with the COPEC Group, one of Latin America’s leading energy groups, a partnership that started three years ago. It lays the groundwork for the two companies to expand their collaboration further through new renewable energy and BESS investments in Chile.

Chile’s BESS market has experienced rapid expansion, emerging as one of the key drivers of global battery storage deployments in April. That month marked a significant milestone when the country surpassed 1GW of operational BESS capacity, according to then-Energy Minister Diego Pardow, following the commissioning of Atlas Renewable Energy’s standalone 200MW/800MWh project.
Notably, the market has been so active that Chile reached its 2027 energy storage deployment target a year early and appears set to achieve its 2050 target by 2027.
Earlier this month, IPP Grenergy completed the sale of Gabriela, the fourth phase of Oasis de Atacama, its flagship energy storage project in Chile, to infrastructure investor CVC DIF.
Last month, multinational power firm Engie announced the start of commercial operation of the Libélula and Los Loros BESS projects on the National Electric System in the country.
Additionally, Enel Green Power, part of the Italy-based power group Enel, launched construction on the Finis Terrae BESS, set to be integrated with the existing Finis Terrae solar PV park in the northern Antofagasta region. 
August also saw developer Limes reach ready-to-build (RTB) stage on a 1GWh project, Verano Energy order a 606MWh BESS from Chinese-based OEM Sungrow, and IPP ContourGlobal start building a 131MW solar PV and 90MW/360MWh BESS project.
