The Utah Board of Water Resources gave formal notice it intends to file an application for a license to build and operate the Lake Powell Pipeline project, which could total as much as 345.4 MW.
The Board of Water Resources filed notice March 4 stating its intention to submit a license application to the Federal Energy Regulatory Commission. The board already holds a preliminary permit to study a 443-MW Lake Powell Pipeline project (No. 12966). (HNN 1/18/08)
The water board said it expects to file a draft license application in March 2010 and a license application in August 2010. If a license is issued in 2012, construction could begin in 2015, followed by water delivery in 2020.
In its most recent filing, the board said the hydro system would feature seven powerhouses and a pumped-storage facility. The board previously mentioned several configurations for the $500 million water supply project, including one scheme that could include as many as six hydropower plants totaling as much as 345.5 MW.
The pipeline would transport Colorado River water about 140 miles from an intake near 1,312-MW Glen Canyon Dam on Lake Powell in northern Arizona to Sand Hollow Reservoir in southwestern Utah. The hydro plants would be located in Kane, Washington, and Iron counties in Utah, and in Coconino and Mojave counties in Arizona.
