Daylight Savings Time Notice
On this date we’ll number the hour endings (HE) in the AESO’s Energy Trading System (ETS) as 01, 02, 02* through to 24 (adding an additional HE 02*) as outlined in Commission Rule 021 Section 18.104.22.168; except for Daily System Measurement (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 the ETS and ensure their submissions for November 6 reflect the addition of HE 02*.
File upload restatements
If a participant attempts to restate using a file upload outside of T-2 during HE 2 on November 6, 2016, an error message will be received. To restate successfully outside of T-2 during HE 2 the restatement must be entered manually by utilizing the Submission > Energy Submission tab.
All importers and exporters within the Western Electricity Coordinating Council must prepare in advance to correctly submit e-tags for the 25 hour day on November 6, 2016, due to the upcoming time change.
Long lead time assets
If you are submitting a start time for a long lead time asset for a time between 1 a.m. MDT and 2 a.m. MST on November 6, 2016, you will receive a message indicating that you need to select the appropriate time zone. A time zone drop down menu will appear after this message is displayed. You will need to re-enter the start time information, select a time zone and submit the start time record again. The start time record will be successful after you re-submit.
