Portland General Electric Company (PGE) announced last Friday that its Port Westward Unit 2 plant went into service Dec. 30 of last year. The 220-megawatt (MW) natural gas-fired plant, located near Clatskanie, Ore., is highly efficient and designed for maximum flexibility in order to meet real-time fluctuations and integrate renewable resources.
The plant utilizes 12 reciprocating engines supplied by Wärtsilä North America. The 25,000-horsepower 50SG engines are the first of their size to run entirely on natural gas. The facility sits adjacent to PGE’s existing natural gas-fired Port Westward and Beaver plants in Columbia County, Ore.
Port Westward Unit 2 can ramp up to full load in less than 10 minutes, allowing it to compensate for wind and solar variability. The facility represents an important component of PGE’s diversified portfolio, and complements the new 267-MW Tucannon River Wind Farm that also came online in December of last year.
Black & Veatch and Oregon-based Harder Mechanical Contractors, Inc. managed the design and construction of the project.
