El Arrayán is a 115 MW facility located on the coast of Chile, near Ovalle. Consisting of 50 2.3 MW Siemens turbines, El Arrayán commenced commercial operations in June of 2014 and is Chile’s largest wind facility. Pattern is a joint venture owner of El Arrayán with a net ownership interest of 70% in the project. Antofagasta Minerals SA, the off-taker, owns 30% of the project.
Approximately 70% of the project's expected output has been sold under a long-term fixed-for-floating hedge with Minera Los Pelambres, one of the world's largest copper mines. The project sells its remaining electricity generation into the Chilean spot market at the prevailing market price at the time of sale. El Arrayán connects to the Sistema Interconectado Central’s 220kV transmission system.
El Arrayán is located on approximately 15,320 acres of coastal land and is leased from a single landowner. The facility entered into a long-term lease agreement with the landowner in January 2012.
