Electric Power project

Spiritwood Station – 99MW Combined Heat and Power Plant Construction

Spiritwood, ND | Great River Energy

Maple Grove, Minnesota-based Great River Energy began work on Spiritwood Station in October 2007. The 99MW coal-fired power plant is part of an industrial park and sits adjacent to a Cargill malting facility. Plans call for Cargill Malt to use 200,000 pounds of steam per hour from the plant in its production processes, making Spiritwood Station the first Combined Heat and Power plant in the state of North Dakota.

When fully operational the plant will generate up to 70 megawatts of baseload electricity and up to 29 megawatts of peaking power.

Scope of Work: Power Plant Construction

MasTec broke ground as the project's civil contractor, handling dirt work, concrete foundations, underground electrical and piping. In the spring of 2009, MasTec became the BOP construction contractor responsible for both civil and mechanical work, adding structural steel, boiler erection and air quality control system installation to the scope of work. At the height of construction, over 400 MasTec employees were on the job.
