To ensure that customers receive a high quality and appropriate standard of service from the electricity distribution network, regulators and governments commonly establish minimum performance standards for the supply of electricity. Distribution performance standards:
- ensure reasonable levels of electricity supply reliability;
- define what the community may expect; and
- guide investment in electricity distribution infrastructure to correct those sections operating below standard.
The current distribution network reliability standards effective 1 January 2008 are at clause 8.6.11 of chapter 8 of the TEC.
The approved maps defining the supply reliability areas and supply reliability categories in three regions may be viewed below:

History of the development of the higher Distribution Network Performance Standards
A joint working group of the Office of the Tasmanian Economic Regulator, Aurora Energy Pty Ltd and the Office of Energy Planning and Conservation is proposing new standards for electricity distribution in Tasmania.
In February 2007 the Working Group released its Final Report including recommended reliability standards:
Distribution Network Reliability Standards - Volume 1: Final Report Summary of Proposals and Overview
Distribution Network Reliability Standards - Volume 2: Appendices to the Final Report
The proposed standards differentiate 101 discrete reliability regions within Tasmania, which may be viewed in the following documents:
Distribution Network Reliability Standards - Volume 3, Part 1: Reliability Areas - North West
Distribution Network Reliability Standards - Volume 3, Part 2: Reliability Areas - North East
Distribution Network Reliability Standards - Volume 3, Part 3: Reliability Areas - South
In November 2006 the Working Group released its Draft Report for public comment:
Distribution Network Performance Standards - Volume 1: Draft Report Summary of Proposals and Overview
Distribution Network Performance Standards - Volume 2: Appendices to the Draft Report
The following submissions were received in response to the Draft Report:
