Connection data

View our progress to connect new electricity generation, energy storage and load projects for our customers.

We’re working at pace to connect new generation, batteries and load to meet New Zealand’s electricity needs into the future. 

In the last few years, there's been a big increase in the number of electricity generation developers with projects they want to connect to the national grid. We're also seeing an increase in projects from electricity distribution networks and others to deliver more power to homes and businesses.

We're working hard to make these all these connections faster and reduce wait times. 

Generation and battery connection projects

We are delivering 13 new generation projects right now which will collectively add 1489 MW to New Zealand's electricity supply, increasing installed capacity by 14%. Our current rate for beginning new investigations is about four per month.

The graphic above is an overview of our progress in connecting new generation and batteries to the national grid. Where projects include more than one type of resource, they are categorised under their primary output (for example, projects of solar + batteries are listed as solar projects). Thirty projects include additional battery energy storage systems.

The order of the projects indicates the order in which we allocate resources, transmission assets and land.

Non-generation customer projects 

We're also delivering 18 projects for our network customers right now, increasing power supply to communities that need it and helping big industrial power users electrify their operations. Use the drop down below to see an overview of the customer projects other than generation and battery connections that we are working on. You can also download this data.

For these projects, we allocate resources based on priority, not necessarily in the order requests are received.

Maps

We have two interactive map tools that may be useful to those interested in projects and connections. 

  • TPR Envision shows current grid capability and where work and investment will be needed in the future. (This information is also presented in our Transmission Planning Report.)
  • Envision Opportunities shows available capacity on our transmission network, to help developers when they are considering locations for new generation.
