Groton Generation Station

Groton Generation Station, Basin Electric's first peaking station near Groton, SD, has two generating units. Each 95-megawatt unit is powered by a GE LMS100® simple cycle gas turbine.

The station is fueled by natural gas supplied from Dakota Gasification Company via the Northern Border Pipeline, and is connected to the electrical grid connected via a nearby substation operated by Western Area Power Administration.

Unit 1 went into commercial operation on July 1, 2006, and Unit 2 went into commercial operation on July 1, 2008.

The station operates as peaking capacity during high market conditions, and is used to meet Basin Electric's power pool obligations. The additional 192 megawatts available from the station will assist Basin Electric in meeting its summer peak load obligations.

Groton Generation Station Unit 1 was the first commercial application of the GE LMS100® simple cycle gas turbine. It was also named one of POWER Magazine's Top Plants six model gas-fired plants for 2007.
