Engines complete journey at Pioneer Generation Station (Video)

Pioneer engines

Six Wärtsilä 20V34SG reciprocating engines arrive at Basin Electric’s Pioneer Generation Station Oct. 29.

It’s been quite a journey for six engines that rolled into Williston, ND, Oct. 29.

The Wärtsilä 20V34SG reciprocating engines, made in Finland, were among 12 total that arrived in Duluth, MN, by cargo ship Oct. 12. They were then loaded onto a train and sent to Basin Electric’s Pioneer Generation Station, northwest of Williston.

The engines arrived earlier than anticipated, and another six are expected to arrive soon. Mark Winn, Basin Electric construction coordinator II, talks about the delivery in the video.

  1. Jack R. Preston, President, Wyrulec says:

    I would like to know why the engines when the station is already operating. What is the horsepower and weight of a Wartzila engine.

  2. In talking to the Engineers on site that did the conversion for HP and pounds – each V-20 cylinder engine produces 12,500 Horse Power and weighs 308,000 pounds. It drives a generator that produces 9.4 megawatts.

  3. Josh Rossow says:

    Jack, The engines are for the Phase III expansion of the Pioneer Generation Station. PGS’s current capacity is 135MW. The twelve Wartsila engines will add an additional 110MW of capacity. See http://www.basinelectric.com/Projects/Pioneer-Generation-Station/ .
