How the mobile substation works.

Keeping rural communities connected

Taranaki communities in and around Douglas and Pātea have been the first to benefit from our new mobile substation, which keeps customers power on while we work.

From July to September 2020, the mobile substation was parked up at the Douglas Substation –

keeping the power on for the Douglas, Strathmore, Huiroa and Toko communities, while we completed essential upgrades, repairs and general maintenance work on the substation.

In March this year, the mobile substation moved to the Livingston Substation to ensure security of supply for Pātea and surrounding communities after a number of unplanned power outages. The cause of the outages ranged from high winds, to blown fuses and equipment failure, of which it was suspected a possum tripped equipment at the substation.

With no back-up supply, in the past, the rural communities would have undergone prolonged and on-going periods of planned power outages so the work could be safely carried out, Powerco Works Project Manager Taranaki and Whanganui, Mike Carson, says.

“Many of our rural substations have a single power supply and, for safety reasons, we have to cut power to customers for any maintenance or upgrade work.

“The mobile substation allows Powerco to divert the electricity supply around the rural substation, allowing it to be removed from service without cutting customers’ power.

“This means minimal disruption to our communities while we continue to work towards a more efficient, safe and reliable network for our customers.”

as Mike Carson takes you on a detailed tour of the mobile substation while at Douglas Substation.

 

Milestones

Substation on the move

After being constructed in 2019 and testing completed, the mobile substation makes its way from the South Island, where it was built, to Whanganui.

Deployed to Douglas

The mobile substation is installed at Douglas Substation in Taranaki, allowing customers to remain connected while essential upgrades, repairs and general maintenance is carried out on the substation.

Supporting Pātea

The mobile substation moves to the Livingston Substation in South Taranaki to ensure security of supply for Pātea and surrounding communities after a number of unplanned outages.

Substation moves to Whanganui’s Castlecliff Substation

The substation moves to Whanganui’s Castlecliff Substation for maintenance on the 33KV switch board and protection upgrade.

FAQ

We strive to minimise impact in the design and placement of network infrastructure and we’re still planning and consulting on the route for the new circuit. The circuit will be a mix of overhead lines – which you will see, and underground cable – which you won’t see. You’ll also see a new building at our Putaruru substation, replacing the ageing existing building there.

We can never guarantee supply 100% of the time, however, the number and length of outages you experience will be reduced.
