City of Spokane: Upriver Dam Hydroelectric Project, Rehabilitation after Failure
The Upriver Dam Hydroelectric Project, City of Spokane, Washington, consists of a 40 foot high concrete dam and gated spillway structure, two powerplants, and a power canal conveying diverted water from the dam to the two powerplants. Approximately $10 million worth of damage occurred when a lightning strike caused a fault on the transmission intertie to the project. The fault triggered a full load rejection of all generating units, causing loss of power to the spillway gates. Efforts to restart the units or provide auxiliary power to the gates were unsuccessful. As a result, the river level rose quickly and water overtopped and breached project embankments. Portions of the power canal were eroded and the foundation of one powerhouse was partially washed away. The papers in this volume describe the accident investigation, repairs to the mechanical structures, and repairs and improvements to the electrical and control systems. Three separate abstracts were prepared for the papers in this report. (ERA citation 13:008686)
