1 Dakota Gasification Company Dakota Gasification Company

2 2 Dakota Gasification Company’s Great Plains Synfuels Plant Concept started in early 1970s Plant built by a consortium of five pipeline companies Construction began in 1981 Synthetic Natural Gas (SNG) production began in 1984

3 3 A new owner….DGC A technological marvel but not a financial success… Original Owners Default The original investors defaulted on August 1, 1985, about one year after first gas was put in the pipeline, due to the very low price of natural gas. DOE Operation Period The DOE operated the plant from 1985 until 1988 Sold to Basin Electric Power Cooperative Basin Electric purchased the plant from the DOE & formed DGC, a wholly owned subsidiary to operate the facility.
