We need to continually operate, maintain and develop New Zealand's transmission network - the National Grid - to ensure we meet the ongoing electricity needs of New Zealanders.
Central Park–Wilton 'B' transmission line experiences heavy salt corrosion and high winds due to being close to the exposed Wellington southern and western coasts. Deterioration of the conductor (wire) has reached a point where replacement is required to continue to provide a safe transmission service.
This line not only helps provide supply to Wellington CBD and southern suburbs, but also connects to the West Wind Generation station. The line crosses mainly Wellington City Council land, including Polhill Reserve, Zealandia and Makara Peak Mountain Bike Park.
