We carry out ongoing network maintenance and upgrade works and whenever possible, we will do this without interrupting your power supply. Sometimes however we need to temporarily disconnect power supplies while this work takes place.
Unless it is an emergency, we will give you at least three working days’ notice before a planned power interruption. This notice may be through advertising, individual notices, telephone, SMS, email, letter or fax. We also publish planned outages on our website and through social media.
If we do need to interrupt your power supply, there are things you should be aware of:
- Access to your meter box may be required. Please ensure all entry gates are unlocked and dogs are properly secured.
- Switch of sensitive electronic and electrical appliances prior to the scheduled power interruption, including TVs and DVD players.
- Cordless phones do not operate without mains power, so keep a standard phone or mobile phone handy in case of an emergency.
- Automatic garage doors, security gates, lift and elevators may not operate during a power interruption, so you may wish to make alternative arrangements.
- Avoid opening fridge and freezer doors unnecessarily during planned power interruptions.
- If you have solar panels, your electricity inverter will automatically switch off when power loss occurs and switch back on when power is restored.
- After the power has been restored please ensure all alarm clocks, reticulation systems and security gates (if you have a monitored security alarm without a backup battery, advise your security company of the power interruption) have been reset.
Please note; we may cancel the planned power interruption due to inclement weather or unforeseen circumstances without notice.
