What City Power reported

City Power’s 12:18 SAST notice identified a cable fault at Greenstone Hill Switching Station. It said four load centres would remain off until repairs were complete. The utility did not give a customer total or an address list, so the number of load centres does not establish how many homes or businesses lost power.

Preparing for another power cut

If you rely on a battery during power cuts, list the devices you need first. The runtime calculator can help estimate how long a battery might run those devices. The internet backup planner can help you work out the power needs of a router or modem.
