The first of two power outages in six Dunedin suburbs is expected from 9am tomorrow.
Delta spokesman Gary Johnson said the power to about 4000 electricity consumers in Abbotsford, Burnside, Concord, Fairfield, Green Island, Ocean View and Waldronville would be interrupted twice tomorrow to enable the safe removal of a fallen tree.
The tree, in a forest between Abbots Hill Rd and the Southern Reservoir, had fallen across high voltage power lines supplying the Green Island substation.
To enable the safe clearance of the tree, the power needed to be redirected from the Green Island substation to near substations.
From 9am tomorrow, some electricity consumers in the suburbs should expect a interruption to their power supply between 30 seconds and 60 seconds to enable the tree removal.
After the removal and the high voltage cable was made safe, there would be a similar interruption to the power supply later in the day.
"Apart from the two brief interruptions, we expect power supply to be on as usual.''
People using medical equipment that relies on electricity should ensure they were prepared for the power interruptions and if there was an immediate health threat to contact their health provider or call 111.
