2005 Data Summary – Median Hydro • CA • Data set complete – ready for review • New HTC K value/p factor calculations for improved modeling • K values derived from 2002, 2003, 2005, and 2010 generation/load data • Reviewed HTC plants, cut some out based on poor K, R2 and added some • Added – King River (Average K = 2.32, Average R2 = 0.29) • Removed – Devil Canyon (Average K = 0.95 ,Average R2 = 0.19) • NW • Data set complete – ready for review • Big 4 plants • K values derived from 1999, 2001-2003, 2005-2010, adjusted for wind reserves • New HTC plants • Mossyrock, Oxbow, Pelton, Ross • East • Data set complete – ready for review • New HTC plants • Hoover, Blue Mesa • Alberta • Data set complete – ready for review • New HTC plants • Bow River, Brazeau, Bighorn
CA K value adjustments • Averaging several water years smoothes K value – lower standard deviation • 2022 – 2002, 2003, 2005, 2010 • 2020 – 2002, 2003, 2005
CA K value adjustments • Improved standard deviations in nearly all cases
NW K value adjustments • Averaging several water years smoothes K value – lower standard deviation • 2022 – 1999, 2001-2003, 2005-2010 • 2020 – 1999, 2002, 2003, 2006
NW K value adjustments • Improved standard deviations in all cases
