Mokoia substation project
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.
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.
There are 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. 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. The 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.
Hutt Valley gas supply upgrade
A section of the gas network that supplies the Hutt Valley is going underground.
Powerco will start work mid-January to replace the existing 40-year-old gas regulating station on Riddlers Crescent with modern, underground equipment. The project will improve the safety, security of supply and network reliability for more than 20,000 gas customers.
The existing above-ground station will be demolished and land put on the market. This will improve the visual appeal of the residential street.
Modern control equipment is much more compact now and means we can put the equipment underground. The result is a safe, modern and much less obtrusive regulating station, reducing the risks of safety, increasing efficiency and reliability, as well as being easier to maintain.
The almost $1 Million project, which is due to be finished late March, is not expected to result in any disruption to supply.
