There are three categories of electricity transmission services:
- Prescribed transmission services relate to services provided by Transend as monopoly services to many customers under the revenue cap. They are subject to significant regulation under the National Electricity Rules. Prescribed transmission services include shared network services to load customers and connection services provided to Tasmania’s distribution company, Aurora Energy.
- Negotiated transmission services are monopoly services provided by Transend to one or a small number of customers. As such, they are subject to lighter-handed regulation under the Rules. Negotiated transmission services include connection services in Transend’s substations related to a new wind farm or a new load customer.
- Non-regulated transmission services are provided by Transend on a contestable basis and are not subject to regulation under the Rules as there is already effective competition. Non-regulated transmission services include operations and maintenance services provided on privately-owned transmission lines, as well as connection services between our substations and our customers’ remote sites.
Prices for prescribed transmission services are determined using a methodology approved by the Australian Energy Regulator (AER). For more information please read our pricing methodology that applies during the regulatory control period from 1 July 2009 to 30 June 2014.
