Editor’s Note: Portions of this paper, “Quantifying the Cost of Unit Outages Across the USACE Hydropower Facilities,” were featured in the January 2017 issue of Hydro Review magazine. The full paper is available for download below.
The study discussed in this article focuses on quantifying the consequences of an asset’s failure. The goal of this effort is to produce estimated daily costs of outages partitioned annually by month to better understand both average and seasonal consequences for 54 of the U.S. Army Corps of Engineers’ (USACE) hydropower facilities. In recognition that each plant and region has different access and quality of data available, the scope of the effort also includes a need to develop methodology that is both consistent and reliably available across the nation.
In 2011, USACE developed the Hydropower Modernization Initiative (HMI) to establish priorities for appropriated funding across the regions covered by Western Area Power Administration, Southwestern Power Administration and Southeastern Power Administration. Projects in the Bonneville Power Administration region are funded directly through rates, rather than appropriations, for power-specific investments. This study considers plants included in the HMI program, but is generally applicable to all USACE plants.
