Hydroelectric Plants in Utah

American Fork
Location: UT
Operator: Rocky Mountain Power
Configuration: 1 X 1.05 MW
Operation: 1913
T/G supplier: Pelton Water Wheel, Westinghouse

Quick facts: In Feb 2003, PacifiCorp, resource agencies, and conservation groups signed settlement agreement providing for the decommissioning of the American Fork power plant in Unita National Forest. In its early years, the Upper American Fork Project served the electrical needs of Lehi, American Fork and Pleasant Grove. It was built by Utah County Light and Power Co, eventually absorbed by Utah Power and then by PacifiCorp. The $3.8mn decommissioning project involves removing a 4ft high, 30ft wide concrete dam and scrapping the T/G set. A diversion pipeline collected water 2mi upstream and traversed the north wall of the canyon to the powerhouse. Above-ground portions will be dismantled and removed by helicopter. Title to the original stone powerhouse (shown) will be transferred to the U.S. Forest Service. Preliminary work got underway in Aug 2007. The even older Lower American Fork plant was decommissioned before 1970.

Jordanelle Dam
Location: UT
Operator: Heber Light & Power
Configuration: 2 X 6.3 MW Francis
Operation: 2008
T/G supplier: VA TECH, Ideal
EPC: CH2M, WW Clyde & Co

Quick facts: This project on the Provo River was co-developed with Central Utah Water Conservancy District. It is not licensed by FERC but is authorized through a lease of power privilege from BUREC's Central Utah Project. The powerhouse is at the toe of the Jordanelle Dam and is served by a 72in connection from the outlet conduit. The project is expected to generate 39 GWh/yr. On 13 Dec 2007, the project was certified as a low impact project by the Low Impact Hydropower Institute.
