ETS - Daylight Saving Time Notice
On November 2, 2008, the AESO will switch from Mountain Daylight Time (MDT) to Mountain Standard Time (MST) for all its daily operations.
On November 2, the AESO will number the hour ending in the AESO’s Energy Trading System (ETS) as 01, 02, 02 through to 24 (adding an additional HE 02) as outlined in AUC Rule 021 Section 9.4.6.3 Table 7; except for DSM transactions which will number the hour endings 1, 2 through to 25.
It is the responsibility of all participants with dispatchable assets to log into ETS and ensure their submissions for November 2nd reflect the addition of HE 02.
Thank you for your co-operation in this matter.
Attention Importer/Exporters:
All importers/exporters within the Western Electricity Coordinating Council (WECC) must prepare in advance to correctly submit tags for the 25-hour day on November 2, 2008 due to the upcoming time change.
