Coal-Fired Power Plants in Utah

Bonanza
Location: UT
Operator: Deseret Power
Configuration: 1 X 458 MW
Operation: 1986
Fuel: bituminous coal
Boiler supplier: Foster Wheeler
T/G supplier: WH
EPC: Burns & McDonnell
Quick facts: Deseret is a generation and transmission cooperative that was formed in 1978 by six rural electric cooperatives. The Bonanza Power Project was designed in the late 1970s and early 1980s to serve anticipated loads from oil shale developments in the region. Two units were planned, but after the oil shale boom did not materialize, the second unit was terminated. Primary financing was provided in 1981 by a $900mn REA loan for the generating unit, the Deserado coal mine, a railroad, and other infrastructure. The longwall, underground coal mine is on public lands in Rio Blanco County, CO. Coal is washed and stored at the mine site, then placed on a 3mi conveyer belt and transported to a railhead for shipment on a 35mi electrified line to the Bonanza site. Most of the unitís output is delivered at 345kV to a switchyard at Mona, Utah, where it interconnects with several 345kV lines of Rocky Mountain Power and the 345kV lines of Intermountain Power Project.

Hunter
Location: UT
Operator: PacifiCorp
Configuration: 2 X 473 MW, 1 X 496 MW
Operation: 1978-1983
Fuel: bituminous coal
Boiler supplier: CE, B&W
T/G supplier: WH, GE
EPC: Stearns-Roger, Jelco, Brown & Root, Morrison Knudsen
Quick facts: This power station is named for E Allan Hunter, a former president of Utah Power & Light Co. The 1,000ac site is near Castle Dale. PacifiCorp operates the plant and is majority owner. Co-owners are Deseret Generation & Transmission Coop, Utah Associated Municipal Power Systems, and Provo City. Hunter burns about 4.5mn tpuy of coal from Deer Creek Mine, which PacifiCorp owns and operate, and this is blended with coal from the Sufco, Westridge and Dug Out mines as needed. Water for plant operations is conveyed to the plant by a pipeline from Cottonwood Creek, which is fed by Joe's Valley Reservoir and through a pipeline directly from Millsite Reservoir.

Boiler supplier: CE
T/G supplier: GE
EPC: Stearns-Roger, Jelco
Quick facts: This power station is named for Huntington Canyon and Huntington City. The plant is located on a 1,000ac site. Annual fuel burn is about 3mn tons of subbituminous coal. This is delivered to the plant by a 2.4mi conveyor from the Deer Creek Mine, which PacifiCorp also owns and operates. In Sep 2005, PacifiCorp ordered a new FGD scrubber from Babcock Power Inc for Unit-2 (the first set online at the site).
