The outage, which left about 1800 homes without power, was removed before 7.30pm.
EARLIER: AIR CONDITIONERS across Cooranbong and Martinsville have whispered to a halt on Wednesday evening after 1800 properties lost power.
Ausgrid confirmed they were responding to the outage shortly after 6pm.
Mandalong, Martinsville and Cooranbong residents without power are expected to get it back about 8.30pm.
“Emergency crews are on [the] way,” the utility provider advises.
The reason for the outage remains under investigation.
