Powerco to remove lines over Whanganui River
A $2.2 million programme of electricity network upgrades is planned for Whanganui over the next six months.
Electricity distribution company, Powerco, will undertake four separate projects with the largest being the removal of six overhead supply lines that span the Whanganui River at Hatrick’s Wharf.
Powerco’s general manager of Service Delivery and System Operations, Glenn Sharratt, said the overhead lines connected to the Hatrick substation would be reinstated underground.
“Unstable ground on the southern bank of the river has placed the current network at risk,” he said.
“We will underground the supply from Purua St, along Anzac Parade, across the City Bridge and back along the riverbank to the Hatrick’s Wharf substation.”
Most of the ducting is already in place so disruption to traffic would be kept to a minimum.
“Removing the overhead lines takes away a potential hazard across the river and will also ensure a greater reliability of supply to Whanganui.”
Another major upgrade of the existing network was the laying of underground cable in Whanganui’s northern outskirts.
“This will run for 3km from near the city boundary, along SH3 to Virginia Rd then reconnect with the existing overhead network at the Brassey Rd intersection. This will give us an alternate supply to the Westmere area and act as a back-up supply for Whanganui’s water treatment plant.”
Upgrading of the 33kV overhead network along the same route would also happen at the same time and the final project involved a similar overhead upgrade from the Whanganui grid exit point at Brunswick to the Whanganui East substation.
