Transition Schedule

AEMO is required under new clause 1.56 of the WEM Rules to publish a regulatory instrument called the “Transition Schedule” by 30 June 2023. Clause 1.56.2 of the WEM Rules describes in detail AEMO’s obligation in respect of the Transition Schedule, which is in summary to publish an instrument identifying:

• Information that Participants must submit ahead of NWCD as part of transition activity
• Information AEMO must publish ahead of NWCD as part of transition activity
• The dates on or by which the information must be submitted or published.

The Transition Schedule may only be published with the approval of the Coordinator of Energy. AEMO and other Rule Participants must then provide or publish information in accordance with the Transition Schedule.

Following the approval of the Coordinator of Energy, AEMO has published the following Transition Schedule.
