Northpower Group Limited (Northpower) is an electricity distribution, fibre network and contracting services company, based in Whangarei, New Zealand.
Northpower owns and manages the electricity lines network in the Whangarei and Kaipara districts. The service area covers 5,700 km[6] and extends from Topuni in the south, to Bland Bay in the north. In addition to the residential and commercial customers in the region, the network also serves some major industrial customers including the New Zealand Refinery, Golden Bay Cement and the Fonterra dairy plant at Kauri.[6]
Introduction[edit]
Established in 1920, Northpower has expanded from a Northland-owned and operated electricity distribution network to become a multi-utility contractor operating in New Zealand. The company has three divisions:
- Northpower Network - providing electricity and fibre infrastructure to Whangarei and Kaipara;
- Northpower Contracting - operating throughout the North Island of New Zealand
- Northpower Fibre - rolling out the ultra-fast broadband network in Whangarei and to rural townships in the region.
Ownership[edit]
The company is 100% owned by the Northpower Electric Power Trust on behalf of electricity consumers in the Whangarei and Kaipara districts. The Trust is governed by five Trustees elected every three years at the same time as the local body elections.
The Northpower Electric Power Trust (NEPT) Deed requires that options for the future ownership of shares in Northpower are reviewed every five years. The Trustees of the NEPT must consult with Northpower consumers to determine if the current Trust ownership structure is what consumers want, or if consumers would prefer a change. Following consultation with the people of the Kaipara and Whangarei Districts in 2017, submissions voted in favour of Northpower remaining in consumer ownership.[7]

Network performance[edit]
The Northpower reported the performance of the network for the 2017/18 year as follows:[8][9]
| Parameter | Target | Actual |
|---|---|---|
| System Average Interruption Duration Index (SAIDI) | 117 mins | 163.9 mins |
| System Average Interruption Frequency Index (SAIFI) | 2.8 | 2.97 |
This level of network performance means that average consumer experiences approximately 2.97 outages per year with an average outage time of around one hour for each interruption.
The reliability of the Northpower network is around the middle of the range of performance of the distribution companies reporting to the Commerce Commission under Information Disclosure requirements.[9]
History[edit]
The history of Northpower dates back to 1920 when the Northern Wairoa Hydro Electric Power Board was formed. The main predecessor organisation was the North Auckland Electric Power Board which commenced operations in 1929. The trading name 'Northpower' was adopted from 1 May 1990.
In 1993, Northpower purchased the small hydro-electric power station at Wairua Falls, near Titoki.
The Electricity Industry Reform Act was passed in 1998, and this required that all electricity companies be split into either the lines (network) business or the supply business (generating and/or selling electricity) by 1 April 1999. The energy retail business of Northpower was sold to ECNZ with effect from 1 November 1998, and renamed Northpower Energy. The name was later changed to Meridian Energy (1999). From that point, Northpower was focussed on the operation and maintenance of the distribution lines network.[10]
Wairua Falls hydro scheme[edit]
Northpower owns and operates the Wairua power station owned near Titoki. This station was built in the early 1900s with the first of the generators installed in 1916. The original machines are still operating. The water canal intake was upgraded in 2009 to improve water flow to the station. New weir flap gates have also been installed to provide better water management of the river in flood situations and reduced maintenance costs. The power station’s aging control system has also been replaced to maximise output and reduce outages. A 4th generator was installed at the site in 2007.
The typical annual energy output from the station is 22 GWh.[11]
Subsidiaries[edit]
- Northpower Contracting
- Northpower fibre, a wholesale UFB internet fibre line provider that operates the fibre network, retail ISPs provide internet services to individual homes, schools, hospitals and businesses.
