The AUC will ensure that the applications are complete and will review submissions received.
Those who have made submissions who have been determined by the Commission to have rights
that may be directly and adversely affected by a decision on these applications will be considered
to have standing. If no submissions are received, or if submissions are received from persons
without standing the AUC may make a decision on the applications without further notice or
without a public hearing. Alternatively, the Commission will hold a public hearing if it receives
an objection from a person with standing and further details will be provided in a notice of
hearing.
The AUC must consider the AESO’s assessment of need to be correct unless someone satisfies
the Commission that the need application is technically deficient, or that to approve it would be
contrary to the public interest.
