Base Point/GREDP Analysis 8/4 - 8/5/2010
Settlement Intervals Analyzed = 38,675•During 24 Hour LFC test: 90 Settlement intervals minus 5 with bad data = 85 intervals by 455 Resources
•95.23% Percent of Intervals that Resources passed GREDP and
did not receive BPD charge (36,832)
• 1.02% Percent of Intervals that Resources failed GREDP and received
BPD charge (394)
•3.75% Percent of Intervals that did not match (either fail
GREDP/no BPD or pass
GREDP/with BPD (1,449)
• 1.63% Percent of “no match” intervals that are WGR Resources (631)
• 2.12% Percent of “no match” intervals that are non-WGR Resources* (818)
*These “no match” intervals caused by various exclusions on either side
Base Point/GREDP Analysis 8/4 - 8/5/2010
“No match” WGR intervals caused by mismatch HSL data
Total number of all WGR SCED intervals analyzed = 24,030
62.98% Percentage of intervals SCED HSL less than COP HSL
27.37% Percentage of intervals SCED HSL greater than COP HSL
9.65% Percentage of intervals SCED HSL equal to COP HSL
Options for Reducing Instances of WGR Base Point Deviation Charges:
•Increase QIRR which is currently set at 2
•Increase KIRR which currently set at 10% dead band
•Use SCED HSL in Base Point charge calculation (requires system change)
