What City Power reported about restoration
The utility said operators were working at the site to bring supply back. It did not say what triggered the trip, how many customers lost power, or when any affected addresses could expect electricity to return. The notice did not confirm a switch-on.
In an earlier notice, City Power said operators would investigate an interruption affecting customers in Randpark Ridge, Northwold, Sundowner and Boskruin. Two names appear in both notices: Randpark Ridge and Boskruin. City Power did not link the morning interruption to the transformer trip, so the earlier notice does not establish a start time or add areas to the transformer outage.
