El Arrayán Wind, the largest wind facility in the country, is located on the coast of Chile, near Ovalle. The facility is a joint venture between Pattern Energy and Antofagasta Minerals S.A.
We have established strong relationships with the community of El Sauce and the Town of Punilla. Many positions at our facility have been filled locally and we have supported road development to make the community more accessible to tourists.
El Arrayán Wind sits on approximately 15,320 acres of coastal land. The facility is close to the Fray Joge Biosphere Reserve, a tourist destination popular for its unique biodiversity and over 400 species of flora. We are inspired by the Reserve’s work and have put much energy into caring for the vulnerable flora species on our own site. We have partnered with the University of Chile to monitor plants in situ and in relocation. Our restoration work is complete and our study is ongoing.
The facility generates enough energy to power 200,000 Chilean homes each year and supports the country’s goal to reach 20% of energy from renewable sources by 2025.
El Arrayán Wind consists of 50 Siemens 2.3 MW turbines generating 115 MW. The facility reached commercial operations in 2014.
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 market prices. El Arrayán Wind connects to the Sistema Interconectado Central’s 220kV transmission system.
