PowerNet Limited is the electricity network management company delivering power to Invercargill City, Southland, West Otago and Frankton near Queenstown.

PowerNet was established in 1994 by network owners Electricity Invercargill Limited and The Power Company Limited to develop, manage and maintain their electricity network assets – lines, poles, cables, substations and other equipment, in a cost-effective way.

PowerNet manages the electricity networks of The Power Company Limited, Electricity Invercargill Limited, OtagoNet Joint Venture and Electricity Southland Limited (the Lakeland Network in Frankton).

Based on the regulatory value of the networks it manages, PowerNet is the equivalent of the fifth largest network company in New Zealand, delivering electricity to around 66,000 consumers.

PowerNet and St John

PowerNet and St John have formed a three year partnership to improve public safety and first aid education.
PowerNet’s core focus is safety – safety of the public and safety of the people who work on our networks. We see St John at incidents – such as a car versus a power pole – they attend as first responders, and this takes our collaboration to a higher level.
