Temporary transmission network isolation
Approximate time required to complete application: 5 minutes.
User this service if you're doing work that requires part of the Western Power electricity transmission network (66kV or higher) to be isolated.
*We require a minimum of 16 weeks to plan a transmission network isolation (de-energising a part of the transmission network). If you are planning works within the Danger Zone and it is possible a network isolation may be required it is important to consider this timeframe.
Initial $250 application fee + estimated isolation fee (quote).
The application can be cancelled at anytime. Cancelled applications will be reconciled on an actual cost recovery basis.
Costs will be reconciled on completion of the works; any additional costs will be invoiced and any underspend will be refunded.
