Xcel Energy to spend $12 million to restore 14-MW Shoshone

Xcel Energy said it will spend about $12 million to return its disabled 14-MW Shoshone hydroelectric plant to service by spring 2008 in Colorado.

Xcel shut down the 98-year-old plant June 20 when one of its two penstocks ruptured, flooding the powerhouse and switching yard with water and debris. The event sent eight feet of water and tons of rock and soil into the powerhouse, the utility said.

Xcel blamed the rupture on corrosion found on the exterior of the penstock section that failed.

The company said it would repair and upgrade both penstocks before returning the plant to service. Crews are scheduled to begin the repair and upgrade in September.

Shoshone is one of seven hydro plants owned and operated by Xcel in Colorado. Located east of Glenwood Springs, it generates electricity from water diverted from the Colorado River. Shoshone began operating in 1909, prior to the Federal Power Act, and is not licensed by the Federal Energy Regulatory Commission.
