New substation project 

Tuesday, January 16, 2018

Powerco is about to start work on a $6.9m substation at Mokoia south of Hawera that will enhance electricity supply in the area.

The new substation on Meremere Rd will replace one built in the 1970s to supply power to the Kiwi Dairies plant (now Fonterra) and the surrounding rural community.

Powerco’s general manager of Service Delivery and System Operations, Glenn Sharratt, said the old structure was within the Fonterra complex but no longer supplied the dairy giant.

Fonterra’s energy needs are now met by power direct from the national grid and gas.

“We still have 1650 customers connected to the old substation but there are problems with it being inside the dairy complex such as access and health and safety,” he said. “Some of the equipment is also due for replacement.”

A separate project involves upgrading the Cambria substation’s Glover Rd East feeder which supplies mostly residential consumers near the Hawera CBD.

“This feeder’s present capacity is insufficient to cope with future load growth in this area or to provide support for the Mokoia substation.”

Mokoia would be a single transformer substation and during maintenance would need backup supply from Glover Rd East. The upgrade would triple the Glover Rd East feeder’s capacity.
