- Dec 3, 2021 Proposed Amendment | Stakeholder Comments
In the Letter of Notice for Development the AESO states Section 502.9 contains an outdated reference to the Institute of Electrical and Electronics Engineers Standard C37.118 – 2005 Synchrophasors for Power Systems (“IEEE Standard C37.118-2005”).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.
