Application filed and approved
The Alberta Utilities Commission (AUC) issued Decision 27145-D01-2022 on Feb. 17, 2022 approving proposed amended Section 502.9 effective Mar. 1, 2022.
An application for approval of proposed amended Section 502.9 was submitted on Feb. 1, 2022 to the AUC. For information regarding the application, or on the status of the proceeding, you may visit the AUC’s eFiling site and go to proceeding #27145.
In the Letter of Notice for Development the AESO states Section 502.9 contains an outdated reference to the Institute of Electrical and Electronics Engineers Standard C37.118 – 2005 Synchrophasors for Power Systems (“IEEE Standard C37.118-2005”).
The amendments to Section 502.9 are intended to ensure the legal owners of generating units, legal owners of aggregated generating facilities and legal owners of transmission facilities implementing synchrophasor measurement units in Alberta are aligned with the technical requirements in the most current version of the IEEE Standard C37.118.
