Located on 20,000 acres near Dayton, Washington, the 267-megawatt wind project is one of two large wind projects owned and operated by PGE. The project produces clean renewable energy that helps PGE meet Oregon's Renewable Portfolio Standard, which requires the investor-owned utility to supply 15 percent of the electricity to its customers from qualified renewable resources by 2015 and 25 percent by 2025. The wind farm includes 116 turbines atop 80-meter tubular steel towers to provide about 101 MW, enough to power the homes of about 84,000 residential customers.
Triple Bottom Line
Economic: Locally sourced project materials reduced transportation costs and helped boost the regional economy. Benefits to the community include jobs, income for local businesses, and increased county tax revenue and easement payments to landowners.
Social: The farm provides safe and reliable electric service to approximately 84,000 residential customers. Benefits to the community include jobs, income for local businesses, and increased county tax revenue and easement payments to landowners.
Environmental: The project team aimed to reduce net embodied energy and designed the turbine foundations to reduce the amount of concrete. A significant portion of the construction materials used in the project was sourced locally, and all material excavated during construction was retained and used onsite. The farm is expected to reduce carbon dioxide emissions by 92% during its lifetime compared to a conventional power plant with the same capacity.
The Tucannon River Wind Farm project is the first energy project to receive an ISI Envision award in North America. It provides clean, renewable power at a reasonable price while helping to decrease dependence on fossil fuel energy sources and increase natural energy dependence.
