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 16 new generation projects right now which will collectively add 2,277 MW to New Zealand's electricity supply, increasing installed capacity by 22%. Our current rate for beginning new investigations is about two 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.
For a more detailed view of the generation and battery connection projects (as of 5 Sep 2025), you can download the data below.
Note: 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 15 projects for our network customers right now, increasing power supply to communities that need it and helping big industrial power users electrify their operations. For an overview of the customer projects other than generation and battery connections that we are working on (as of 5 Sep 2025), you can download the data below.
Note: for these projects, we allocate resources based on priority, not necessarily in the order requests are received.
Connections discussion document for consenting authorities
Transpower analysis of the balance between electricity supply and demand over the decade to come shows that Aotearoa New Zealand must deliver new electricity generation faster if we are to reliably meet growing demand for electricity from communities across the country.
We have developed this discussion document to provide consenting authorities with this important context when reviewing and processing resource consent applications for renewable electricity generation facilities. We also welcome existing generators and prospective investors to share this document with authorities when discussing potential new generation facilities or making applications.

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.
