The proposal is for the construction of a standard 22 kV three phase wood pole distribution line from Northcliffe to the Windy Harbour settlement, a distance of approximately 30 kilometres. For much of its length, the powerline would pass through the D'Entrecasteaux National Park and an area which has been proposed as national park under the Department of Conservation and Land Management's (CALM) Shannon Park and D'Entrecasteaux National Park Management Plan 1987/88 and the Management Plan for the Southern Forest Region (CALM 1987).
