- Tucannon River Wind Farm
Portland General Electric saw an opportunity to expand and diversify its wind energy portfolio by acquiring a phase of Puget Sound Energy’s Lower Snake River Wind Energy Project. The next steps required negotiating several critical contracts and management of all the details that went into successful project implementation.
The Tucannon River Wind Farm in southern Washington state is one of the biggest wind projects owned by Portland General Electric (PGE), covering about 20,000 acres. The new wind farm complements the company’s existing portfolio of wind resources by increasing geographic diversity, and it helps PGE meet Oregon’s renewable energy portfolio requirements.
PGE acquired the project from Puget Sound Energy and immediately began negotiations on key contracts for the balance of plant and turbine supply agreement. PGE selected our team to provide owner’s engineer services, including detailed engineering design reviews, project management support and on-site construction support.
The project included 41 miles of new roads, a substation, more than 20 miles of transmission line, and 116 Siemens SWT-2.3-108 turbines. As part of the project development, our specialists provided reviews of the collector system, substation and transmission line design. We also supported the client with road and civil design reviews.
We conducted factory visits, shadow flicker assessments and visual impact assessments. Then during construction we provided on-site support to monitor progress and conformance to design specifications. The project was completed on time and on budget, bringing the client’s added renewable energy installed capacity into operation.
