More than 430 homes and businesses in Perth were hit with a power cut on Monday.
A network fault, which happened at 8.30am, left 436 properties off the grid.
Perth Prison is also understood to have lost power, but was able to use a back-up generator.
SSEN, which looks after the electricity network, sent engineers to resolve the issue – which affected the Shore Road area of the city.
The issue had been fixed by the afternoon.
A spokesperson for SSEN apologised for the issue and thanked locals for their patience.
