The Dunedin City Council told the Herald it was aware of “some outages” involving street lights this evening.
“We’re investigating the cause through our system and providers. Affected lights are now returning to normal.”
Aurora Energy said the outage was caused by an issue with its ripple injection system, which sends coded signals over power lines to automatically switch groups of streetlights on and off at dusk and dawn.
The company said the streetlights were out from about 6.50pm to 8.10pm. They went out again shortly after 9pm before returning about 9.30pm.
Aurora said the later outage was caused by a separate issue and a fault response crew was investigating.
It said the issue did not affect customers’ electricity supply.
“We apologise for the inconvenience this caused, especially with the evenings now darker after the end of daylight saving,” Aurora said.
