Our Networks

Our centralised Network Management Centre in New Plymouth monitors Powerco's gas and electricity networks.

Electricity networks

Powerco distributes electricity to 336,000 urban and rural households, businesses and major industrial and commercial sites in New Zealand's North Island. Our networks are in the Taranaki, Wanganui, Rangitikei, Manawatu and Wairarapa regions, including the urban centres of New Plymouth, Wanganui, Palmerston North and Masterton, as well as Tauranga and the surrounding rural areas and the eastern and southern Waikato, Thames and Coromandel regions

Customised Price-quality Path 

In March 2018 the Commerce Commission set a Customised Price-quality Path (CPP) for Powerco’s electricity networks. This is a significant milestone in Powerco’s history.

We have been given approval to spend $1.27 billion (over five years) on a major electricity network upgrade - a third more than we spent in the previous five years.

Much of Powerco’s electricity infrastructure was built in the 1950s and 60s and is in need of replacement. The network is also under increasing pressure from regions with strong growth.

The investment plan includes 40 network development projects and allows for routine growth projects. Powerco will report annually to the Commission and its customers on progress.

The CPP proposal was centered around three main themes our customers told us they wanted. 

  • Ensure the network is safe, secure and resilient
  • Support the growth of our communities
  • Evolve the Powerco network for the future

Gas networks

Powerco distributes natural gas to more than 106,000 North Island households, businesses and industries across its distribution networks of over 6,170km.

Powerco's gas networks are in the Taranaki, Manawatu, Hutt Valley, Porirua, Wellington City, Horowhenua and Hawke's Bay regions. The gas is drawn from the transmission system owned and operated by First Gas.
