AESO publishes a point forecast with no confidence interval, so no band is shown.
AESO republishes its load forecast through the day. Each publication is kept as it was retrieved, so a past hour is plotted with the forecast that existed before the hour began and future hours with the newest retrieval.
The time attached to each forecast is when Ask the Grid retrieved it, within fifteen minutes of AESO updating it. It is not a publication time AESO states, so the scorecard compares the forecast available a day ahead rather than a precise lead time.
The settled line is Alberta internal load from AESO's current supply and demand report, read every five minutes. AESO's hourly settlement figure for an hour arrives after the hour ends.
