WEL Networks

WEL Networks Limited is an electricity distribution company, serving the northern and central Waikato region of New Zealand. WEL is the sixth largest electricity distribution company in New Zealand, with 100,142 connections and of lines and underground cables. The company is 100% owned by the WEL Energy Trust.

History

WEL was formed when legislation in 1988 amalgamated the Central Waikato Electric Power Board with Hamilton City Council's Electricity Division from 1989 to form Waikato Electricity Limited. After amalgamation, ownership of WEL was vested in the Waikato Electricity Authority (WEA). WEA formed WEL Energy Trust in 1993, with the first election in June, so that the community could have some ownership of WEL. In 1992 a third of WEL was sold to Utilicorp for almost $40m, a third retained for the Trust and a third given to customers. The Electricity Industry Reform Act 1998 forced WEL to sell its retail business. It sold to the State owned (but later bought as NGC by Vector Limited) Natural Gas Corporation for $89.9m. The Trust then bought back all WEL's shares to become its sole owner. In 2001 WEL was renamed WEL Networks Ltd.

After the Trust's 2003 elections it reduced grants given to community groups and started paying discounts to customers. By 2014 the Trust had paid over $240 million to customers in discounts, but had also invested over $60 million in community and energy efficiency grants. In 2014–15, over $2m was paid in grants.

WEL Networks formed a joint venture in 2010 with Waipā Networks and Crown Fibre Holdings to establish Ultra-fast Fibre Limited, a company that owns and operates the fibre network in Hamilton, New Plymouth, Tauranga, and Whanganui. In 2016, WEL and Waipā Networks paid $189 million to take 100% control of the Ultra-Fast Fibre company. In 2020, WEL and Waipā Networks sold their interest in Ultra-fast Fibre to Japanese-owned First State Investments for $854 million.

In 2022, the company announced the construction of New Zealand's first utility-scale battery energy storage system (BESS), to be located at Huntly. The system is rated at 35 MW, and is capable of storing energy equivalent to the daily demand of over 2000 homes.

Distribution network

WEL's distribution area covers the Hamilton City and the majority of the Waikato District, including the towns of Ngāruawāhia, Huntly, Te Kauwhata and Raglan. The distribution network is supplied from the national grid at three grid exit points (GXPs): Hamilton (Ruakura Road), Te Kowhai, and Huntly. WEL Networks uses 33,000 volts for subtransmission and 11,000 volts for distribution. As is standard in New Zealand, electricity is delivered to homes at 230/400 volts (phase-to-neutral/phase-to-phase).

Statistics

Regulation

As a natural monopoly electricity lines business, WEL Networks is subject to regulation under the Commerce Act 1986. However, as WEL Networks is 100% owned by a consumer trust, it is not subject to price-quality regulation, but is subject to Information Disclosure regulation. The Commerce Commission publishes a wide range of Information Disclosure data provided by WEL Networks, and prepares analysis and summaries of that data.

Te Uku Wind Farm

Te Uku Wind Farm is located at Te Uku near Raglan. It has a capacity of 64 MW using 28 wind turbines. Construction was completed in March 2011, at a cost of $200 million. The farm covers an area of approximately . The wind farm is jointly owned by WEL Networks and Meridian Energy.

Resource consent was granted in May 2008 and appeals were resolved by November 2008. Construction of the wind farm began in 2010. Hick Bros Civil and Spartan Construction won an award for outstanding technical and environmental planning. The wind farm was officially opened by Prime Minister John Key in February 2011. Te Uku was fully operational on 10 March 2011.

Te Uku Windfarm is controlled from Wellington where Meridian has its control centre for running all of their New Zealand Hydro and Wind generation assets.

The windfarm is linked to the national grid at Te Kowhai substation by about of 33 kV lines on 159 steel poles built on concrete pile foundations and an underground cable from just west of Waitetuna Valley Rd to Cogswell Rd, a total of about .

Incidents

On a particularly cold winter night in August 2021, the National Grid operator Transpower, gave an emergency instruction to WEL Networks to reduce its demand from the grid by 20%. This resulted in power cuts for around 18,000 WEL Networks customers. The demand restrictions required of WEL Networks were significantly greater than for other networks. Transpower subsequently admitted an error in their calculation of the required demand reduction. WEL Networks estimated that they would only have been required to disconnect 1,373 customers (instead of almost 18,000), if the error had not been made. Transpower and was eventually fined $150,000 for their part in contributing to the loss of supply to customers.
