Mar 2024 Transgrid has released its Preferred Route Report for the NSW component of the Victoria to NSW Interconnector West project. The Report responds to feedback on the Draft Route Report released in January, and includes modifications to move the proposed transmission line further north of the Moulamein township and widen the route by up to three kilometres at the eastern end near Dinawan.
