Utah water district seeks contractors for 12-MW Jordanelle

Central Utah Water Conservancy District seeks applications for pre-qualification of construction contractors for its 12-MW Jordanelle Dam hydroelectric project, north of Heber City, Utah. Responses are due June 9.

The project involves construction of a hydropower plant at the Bureau of Reclamation’s Jordanelle Dam, including construction of a secant pile wall and sheet pile-type dewatering cutoff, along with rock and common excavation near the dam outlet works.

An 84-inch-diameter steel penstock is to connect to the dam’s outlet works and then bifurcate into two 66-inch-diameter branches conveying water to the turbines through butterfly-type inlet valves. The reinforced concrete power plant will house two horizontal Francis turbines, each rated at about 300 cubic feet per second. The turbines will drive synchronous generators with output ratings of about 6 MW each and speeds of 360 rpm. A control room will be built adjacent to the turbine floor to house the plant control panel and switchgear.

VA Tech Hydro holds equipment contract

Central Utah awarded a $5 million contract in December to VA Tech Hydro Canada Inc. for turbines, generators, hydraulic power and control units, plant control system, turbine inlet valves, anchorage materials, and special services during installation, testing, and startup.

An information packet is available at no charge from Central Utah Water Conservancy District, 355 W. University Parkway, Orem, Utah 84058; (1) 801-226-7125; Fax: (801) 226-7111; and from the district’s Internet site, www.cuwcd.com. Pre-qualification proposals are due by noon June 9.

The district’s tentative schedule calls for pre-qualified contractors to be notified June 22. Final plans and specifications are to be available July 6. A mandatory pre-bid meeting is set for 10 a.m. July 13. Pre-qualified contractors will be invited to submit bids by 2 p.m. Aug. 8. The contract is to be awarded Aug. 16. Construction is set for September 2006 to May 2008.

The Department of Interior approved a lease of power privilege for the project in 2005, enabling the district to proceed with development. Central Utah, which estimates construction costs will total $9 million, plans to sell all power generated to Heber Light &Power, a municipal utility.
