Traffic lights went dark in Perth this morning after the city centre was hit by a power cut.
Shops and offices were also left without electricity for several minutes.
The outage also affected music-lovers hoping to buy tickets to 80s festival, Rewind, which is taking place at Scone Palace this weekend.
Perth Concert Hall was without power for longer than other buildings in the area and was only able to accept cash for those looking to pay for tickets.
Additionally all online sales were suspended and the caf closed while the building was without power.
Colin McMahon, Horsecross chief executive, said they hoped to be back up and running by late afternoon.
He said: “The electricity board is going to supply us with a generator until they can get the fault fixed.We hope it should be here by 1pm and that online sales will be back up by 3pm.
“The power went off at about 7.30am and came back on for about 15 or 20 minutes before going off again.
“We have an emergency power facility and we are monitoring that and trying to stay open as long as possible. However we have taken the decision to close the caf because we’re not in a position to serve food.
“We apologise to our customers.”
Perth Museum and Art Gallery had a partial power outage and while the building was able to remain open some exhibits, including the Natural History gallery, were closed off for safety.
A spokesman for Scottish Hydro said the incident was caused while engineers tried to fix a fault in their network.
He said: “The power first went off at 7.40am, affecting about 80 customers.As part of the work to restore power some customers may have noticed a dip in power, while some may have lost power for a couple of minutes.
“The fault was in part of the underground network near the Concert Hall and our engineers are still working there.We would like to apologise to customers for any annoyance or inconvenience caused by the interruption in power supplies.”
