Occasionally, ETSA Utilities, South Australia’s distribution network service provider, will make the decision to disconnect the supply of electricity in emergency situations.
This decision is not taken lightly and only occurs in serious situations. The provisions of the Electricity Act 1996 (the Act) empowers ETSA Utilities to disconnect the supply of electricity to any location if it is considered necessary to do so to avert danger to people or property, particularly due to bushfire danger. If practicable, ETSA Utilities consults with the Country Fire Service (CFS) before disconnecting supply. In making a decision to disconnect, ETSA Utilities also considers the Bureau of Meteorology’s weather information to assess the latest conditions and warnings.
For example, in situations where there is the possibility of electricity assets contributing to starting fires (typically on days with extreme temperatures and strong winds), supply to certain power lines may be disconnected to avert the possibility of sparks from clashing power lines causing fires.
ETSA Utilities initiates public notification of emergency disconnection through the media. As recommended by the CFS, a battery powered radio tuned to 891ABC should be used to be kept informed of emergency notifications on days of extreme fire danger.
In accordance with the Electricity Distribution Code (the Code), ETSA Utilities is required to provide a 24 hour emergency line giving information on the nature of the emergency and an estimate of the time when supply will be restored. ETSA Utilities must also use its best endeavours to reinstate supply as soon as possible.
The Code also sets out service standards for supply interruptions which, if exceeded, ETSA Utilities is required to make Guaranteed Service Level (GSL) payments to customers. However, under the provisions of the Act, ETSA Utilities does not incur any financial penalty for disconnections under emergency conditions and as such, emergency disconnections are not included for the purposes of GSL payments.
