We have now published our draft decision on Marinus Link's Stage 1, Part B (Construction costs) electricity transmission determination for the 2025–30 regulatory control period.

Consumer engagement is a valuable input to our determination. Stakeholders can assist in our process by providing their views on aspects of the initial draft decision.

On Tuesday, 27 May 2025 at 10:30am, we will host a predetermination conference to allow stakeholders the opportunity to ask questions about our initial draft decision. You can register your interest on Eventbrite here.
