UDI ranks least-cost steam generating plants

The least-cost producer of electricity in the United States during the five-year period from 1990 to 1994 was Basin Electric Cooperative`s 1,710-MW Laramie River Station near Wheatland, Wyo., according to a five-year production cost analysis for more than 700 U.S. steam-electric power plants published by the Utility Data Institute (UDI). The three-unit, coal-fired Laramie River plant also topped the rankings in the last three five-year studies.

The top five low-cost producers of electricity, ranked on a five-year average cost including fuel are: Laramie River, $9.53/MWh; MR Young, a 673-MW coal-fired plant operated by Minnkota PowerCooperative in Center, N.D., $10.17/MWh; Dave Johnston, an 817-MW coal-fired plant operated by PacifiCorp in Glen Rock, Wyo., $10.79/MWh; Nebraska City, a 616-MW coal-fired plant operated by Omaha Public Power District in Nebraska City, Neb., $11.34/MWh; and JE Corette, a 163-MW coal-fired plant owned by Montana Power Co. in Billings, Mont., $11.47/MWh.
