Planned Computer System Maintenance - Measurement

Notice Text

TC Energy would like to notify customers that due to required monthly computer system maintenance, hourly measurement data may be unavailable from:

- October 18, 2024, at 7:00 PM CT until October 19, 2024, at 05:00 AM CT

- October 19, 2024, at 10:30 PM CT until October 20, 2024, at 05:00 AM CT

Impacted measurement will be extrapolated to the end of the October 18th gas day and then the remaining hours will re-calculate once the updated measurement is received.

The 5:00 AM preliminary Gas Day Summary Report (GDSR) will run as per the routine schedule; however, it is possible that all the extrapolated hourly measurement will not be captured until the final version of the GDSR is published at approximately 10:00 AM.

Operators with access to the hourly and daily Volume Energy Composition Report (VEC) will see updates to hourly measurement once the outage is complete and the outstanding hours are updated in the system.

OBA Reports should not be impacted as it is expected the measurement will be updated prior to the conclusion of the physical gas day.

For further information please contact The Call Centre in Calgary at 403-920-7473 or toll free at 877-920-7473
