Electricity supply upgrade progressing well

Tuesday, October 03, 2017

An early stage of Palmerston North’s massive electricity supply upgrade is nearing completion.

Powerco contractors will soon complete trenching work skirting the city’s CBD and are preparing to install new cabling over the next few months.

Powerco’s General manager of service delivery and systems operations, Glenn Sharratt, said the trenching and installation of ducting had covered about 10km.

“It has been a challenging, steady-as-she-goes task because of the number of underground services encountered. In our planning we estimated 100 would cross our route. However, that’s already passed 300 and we haven’t finished.”

“The new cables will replace the existing network and boost security of supply to the city centre,” he said.

That should be wrapped up early next year then work would start on the next phase of the five-year project.

“This includes boring under the Manawatu River to install at least one duct and trenching a route from the city side of the river to a planned new substation on the corner of Ferguson and Linton Sts.”

“We are working with the Palmerston North City Council to attach the remaining ducts to its proposed, 190m, He Ara Kotahi cycle and pedestrian bridge.”

Powerco is awaiting a council decision on the bridge project before finalising its ducting plans.

“Once we get that ducting in place the next phase will involve laying underground cables from Transpower’s substation at Linton to the river.”

That will cross Massey University’s dairy farm and reserve land.

”I can’t speak highly enough of the cooperation we have received from the council, Massey University and the Rangitane iwi. All three parties have been great to work with.”

Mr Sharratt said one of the key aims of the project was to transfer supply pressure from the Transpower Bunnythorpe substation to the Transpower Linton substation.

The new Linton and Ferguson St substations would future proof supply to Palmerston North.
