Aurora Energy is commissioning a new transformer to "significantly increase" network capacity to the district.
The 50MVA auto transformer will be connected to the existing Upper Clutha network at the Cromwell grid exit point between mid-October and mid-November.
It is an addition to two existing 36MVA transformers.
Aurora Energy general manager of service delivery Richard Starkey said this week commissioning was timed to happen outside summer and winter peak electricity demand, and planned power outages would not be required as part of the work. Mr Starkey said the extra capacity would help "future-proof" the network and was a response to the high level of growth in the Upper Clutha.
"As a key driver of the regional and national economy, it’s vital Upper Clutha and Wānaka have a network that can support a growing population and how people choose to use electricity now and as new technology becomes available."
The main part of the work was completed in July this year, with the groundwork and installation of the auto transformer and associated equipment.
The transformer reduces the voltage of electricity coming from Transpower so it can run through substations in the district.
Aurora communications and engagement lead Simon Wong explained the new transformer enabled Aurora to "push through more electricity" should there be a need for it.
"So that means if there's high demand in summer or winter it isn't going to be an issue."
"This will take us, probably ... into at least the next 10-plus years."
