Faced with a strong growth in demand for electricity by its member cooperatives and the need for a long-term asset to provide the generation to meet that growing demand, Great River Energy started construction of Spiritwood Station, a 99 megawatt combined heat and power plant located just east of Jamestown, N.D., in October 2007.
The power plant, built at a cost of $424 million, will generate electricity for the regional electricity market, and provide process steam to a malting facility located adjacent to the plant. When fully utilized, Spiritwood Station will be about 66 percent efficient. This compares to about 30-35 percent efficient for most coal-based power plants in the United States. Also, the plant will utilize the best available emissions control technologies, making it one of the cleanest power plants in the country.
The plant in service date is being delayed. During the construction phase, the United States was unexpectedly hit by the recession, and Great River Energy’s five-year forecasted growth dropped from a strong 2.5 percent prior, to a marginal 0.5 to 1.0 percent. Prices also dropped in the regional electricity market, and the loss of a proposed ethanol plant that would have used process steam from the plant, resulted in a challenging short-term outlook for Spiritwood Station.
Thus, Great River Energy made a decision in August 2011 to delay the in-service date of Spiritwood Station past 2012. The delay of the in-service date will minimize the cost impact to members and will help to maintain the competitiveness of our rates. Great River Energy’s members will again need more baseload electricity in the future, and that will help make Spiritwood Station a valuable long-term investment. This will occur as demand and electricity prices increase via a turnaround in the economy, and as additional markets develop for the available process steam from the plant.
Last fall, we finished commissioning activities at Spiritwood Station with successful results. In November, employees immediately started a protect, preserve and maintain mode at plant. That included drying the boiler and piping systems, cleaning equipment, moving all coal, lime and ash offsite, and site cleanup. Current activities include monitoring preservation of equipment, running lube oil systems, running conveyors to preserve the belts, turning motors, and performing other preventive maintenance activities. A 2013 operational plan for Spiritwood Station will be developed later this year.
