South Waikato national grid connection project begins by building solid foundations

Wednesday, June 03, 2020

Powerco has recommenced work upgrading the Putaruru substation as it embarks on a significant project to build a new connection to the national grid in the South Waikato.

Construction of a new building to replace the ageing one started in December. While work was delayed due to COVID-19 lockdown restrictions, activity is back underway and is due to finish at the end of June.

Once complete, the building will be used to house upgraded switchboard equipment. Powerco Network Development Manager Neville Goodwin says this future-proofs the substation as part of a larger project to build a new national grid connection.

“Currently about 11,500 addresses in the Putaruru, Tirau and Matamata areas are supplied with electricity via a single line from Transpower’s Hinuera substation – which means loss of power when the line is out for maintenance or there’s a fault,” he says.

“Powerco is building a new circuit from the Arapuni power station to our Putaruru substation to help ensure safe, reliable and resilient supply in the South Waikato area.”

Planning for this phase of the project is underway.

The team will continue to minimise disruption as the substation upgrade continues, and to provide advance notification to customers in the area if there will be any power outages as part of the work.
