PGE completes 267 MW Tucannon River Wind Farm

Portland General Electric Co. said its Tucannon River Wind Farm is in service and available to generate power for PGE customers. Tucannon River is PGE’s second fully owned and operated large-scale wind project, with 116 turbines and a total installed capacity of 267 MW.

Given the variability of wind power, the plant is expected to produce an average of 101 MW — enough to power the homes of about 84,000 average PGE residential customers.

Tucannon River Wind Farm is located on 20,000 acres near Dayton, Wash. The new wind farm complements PGE’s existing portfolio of wind resources located in Eastern and North-central Oregon: Biglow Canyon Wind Farm, which is fully owned and operated by PGE, and power purchase agreements for the output of the Klondike II and Vansycle Ridge wind farms.

By securing wind power from different geographic locations, PGE is able to better integrate wind into the system because the facilities are less likely to cycle up and down simultaneously.

In addition to providing carbon-free and emissions-free generation of electric power, Tucannon River is providing economic support to the region.

Tucannon River was built for PGE by general contractor and independent renewable power developer Renewable Energy Systems Americas Construction Inc. using wind turbines manufactured by Siemens, each with a nameplate generating capacity of 2.3 MW.

Power generated at Tucannon River will be brought to PGE customers via a new interconnection at Central Ferry Substation constructed by the Bonneville Power Administration. The plant was completed on time and on budget under fixed-price contracts, with final construction costs expected to be about $500 million, excluding AFDC.

Completion of Tucannon River Wind Farm is a significant milestone in the implementation of the action plan that came out of PGE’s 2009 Integrated Resource Plan. The plan was acknowledged by the Oregon Public Utility Commission in November 2010. The requests for proposals used to select the project were conducted pursuant to competitive bidding guidelines established by the OPUC, using objective scoring criteria intended to identify projects that provide the best balance of cost and risk while meeting PGE customers’ needs for reliable, affordable electric power.

Portland General Electric, headquartered in Portland, Ore., serves more than 843,000 residential, commercial and industrial customers in Oregon.
