If I’m in an embedded network, can I choose my electricity retailer?

In most states you can purchase from your retailer of choice. 

If you opt for an external retailer, simply inform them that your tenancy is part of an "Embedded Network" and that you are interested in an "Energy Only" offer.  Depending on the retailer, they might want to install a new meter at your cost. You will also receive two bills; one from the retailer for usage another from the Centre for the regulated network charges. You are still responsible for electricity used until such time your authorised retailer takes over the billing rights.
