Bird may be responsible for power outage: Ergon
UPDATE: ERGON Energy believes a bird may be responsible for a power outage that left 2500 customers in the dark last night.
1950 customers lost power when a 33,000 volt line between the Warwick bulk supply point and Allora substation fell at 6.08pm.
The fallen line came into contact with an 11,000 volt feeder line underneath it, knocking power out to another 550 customers 10 minutes later.
The fault current created by the lines clashing caused a loud bang from the nearby transformer, but it did not sustain any damage and the 11kv line remained intact.
Customers supplied from the Allora substation had their power restored within two hours, with the substation renergised from Clifton.
Power remained of to customers on the Ogilvie Rd feeder in Warwick for another hour and 15 minutes while crews repaired the 33kV line.
Power was fully restored to all customers just after 10pm.
An Ergon Energy spokesman said crews were not able to identify a specific cause for the fallen the powerline.
"A bird strike that caused the 33kV lines to clash was a possible cause," he said.
9AM: POWER has been restored to homes across the region, after a series of transformer explosions knocked out power to more than 2500 residents overnight.
An update from Ergon Energy about the cause of the outage is expected later this morning.
6PM: HOMES across the Southern Downs have been plunged into darkness after fallen cables at a service station sparked a series of transformer explosions in the area.
Thousands of homes in north-east Warwick, Sladevale, Freestone, Allora, Clifton, Goomburra, Massie, Deuchar, Gladfield, Gengallan, Maryvale and Pratten are without power.
At least 2500 customers are affected.
The outage was sparked after a 33,000 volt cable and an 11,000 volt cable were downed at the Caltex Service Station north of Warwick.
The cables crossed as they fell, causing transformers to explode.
Fire crews are at the scene of the Caltex Service Station, directing people away from the fallen powerlines.
Ergon Energy crews are on their way to site.
There's no estimate at this stage of when power will be restored.
