Pioneer Generation Station
Fuel: Natural Gas
Location: Williston, ND
Output: 247 megawatts
Pioneer Generation Station northwest of Williston, ND, was built to serve the increasing demand for electricity by member cooperatives in northwest North Dakota.
Unit 1 started commercial operation in 2013, Unit 2 and Unit 3 started commercial operation in 2014. Each of the three units has 45 megawatts (MW) of generation capacity giving the station a total rating of 135 MW.
Unit 1 of Pioneer Generation Station features a clutch that allows the turbine to uncouple from the generator, allowing the generator to provide transmission system voltage support. This feature, if needed, is used to provide fast-acting reactive power which will stabilize the transmission system in the area.
Phase III of the station, which started commercial operation in 2017, features first-of-its-kind engines for Basin Electric: 12 natural gas-based reciprocating engines, each with a generating capacity of 9.3 MW.
