Utility Seeking Power
Wärtsilä supplying gen-sets, equipment for Oregon-based power plant
Twelve Wärtsilä 50SG will be used to power the Port Westward Unit 2 plant, which is being built for Portland General Electric Co.
Wärtsilä received an order to supply the generating sets and related auxiliary equipment for a new power plant being built near Clatskanie, Oregon, U.S.A.
The Port Westward Unit 2 plant is being built for Portland General Electric Co., an investor owned utility. It will be powered by 12 Wärtsilä 50SG natural gas-fuelled engines with an electrical output of 220 MW. The plan should be fully operational by 2015.
The Wärtsilä 50SG gas engine will allow Portland General Electric to have the operational flexibility to quickly respond to variable input levels of wind and hydro power to the system.
The Wärtsilä 50SG is a four-stroke, spark-ignited gas engine operating on the Otto cycle. It incorporates the lean-burn principle and has been designed using the Wärtsilä 34SG engine. An important feature of this engine is its high power plant net electrical efficiency rating at high ambient temperatures, which reach more than 50% in combined-cycle mode, the company said.
