Comparison to new GV run by Sherman with loads reduced by 3.4% to back out transmission losses. Note large difference in coal generation.
In general, the trade-off is between coal and combined cycle generation, and appears to be caused by differences in the commitment and dispatch logic. Since the hurdle rates and tie limits effectively separate Alberta from other areas, initial analysis can focus there.
Next step is to compare planned and forced outage results. Something is causing Gridview to reduce coal generation much more frequently than Promod.
