Transpower outage takes out most of Wellington for 90 minutes

A fault on the national grid caused a power outage affecting 84,000 Wellington customers for approximately one and a half hours this afternoon.  

The fault occurred in the Wilton sub-station, where "vital maintenance" was being undertaken on one of the "buses" delivering a power feed to central Wellington, grid operator Transpower said.

Another bus at the substation, which was carrying load instead, failed, removing the back-up that is always supposed to be available while maintenance is occurring.

Power was restored just before 4.30pm.
