Across the sector, more than 1000 MW of new generation, batteries and capacity upgrades are expected to be delivered this calendar year. That will increase Aotearoa’s total installed generation and battery capacity by more than 1o%.
There are many more projects in the future pipeline as well. Take a look below at the data to track the future of New Zealand's electricity mix.
Tracking our connections pipeline and enquiries
As of 8 November 2026 we are delivering 15 new generation projects which will collectively add 3,106 MW to New Zealand's electricity supply.
The graphic above is at 8 November 2026 and provides an overview of our progress in connecting new generation and batteries to the national grid. Some projects include more than one type of resource (for example, projects of solar plus batteries). Stage counts show the number of Transpower connections, while technology counts represent the number of technologies connecting.

We track and manage new connection enquiries from initial enquiry through to commissioning. Our Connection Enquiries Dashboard provides an aggregated view of our forward pipeline of works by number and size (MW) noting connection types and subtypes, their locations (by planning region), need dates (by Regulatory Control Period) and enquiry stages. The data displayed is from the start of Regulatory Control Period 4, which began on 1 July 2025.

We are focused on connecting our customers efficiently and prioritising a secure supply for New Zealand
Completing projects to connect more generation means more electricity is available across New Zealand.
More available electricity puts downward pressure on generation prices.
More locations for generation also means more flexibility in how electricity can be moved around New Zealand, increasing resilience at a regional level.
And as New Zealand adds more renewable generation to the system, less non-renewable generation is needed overall.
Large batteries add flexibility and firming options to the overall power system as well as adding resilience benefits.
As electricity use increases, more infrastructure is needed to deliver it to homes and businesses. This means local lines companies need us to be building new substations and increasing capacity and resilience at others.

An open access network
Transpower operates New Zealand’s electricity transmission network on open access principles, which allow users to connect to the grid where it is technically feasible. Early in the connection process we provide information to the prospective users including whether there is sufficient grid capacity and whether there are constraints that the new user would need to operate within such as restricting their usage at certain times. We manage the integrity of the transmission network, including ensuring the grid remains stable and supply is secure. Connected assets (new and existing) must also meet the Electricity Authority’s code and compliance requirements.
In our role as System Operator, we produce a ten-year forecast known as the Security of Supply Assessment (SOSA). This takes a high-level view and looks at existing generation and demand, committed projects and potential future developments around the country under a range of supply and demand scenarios. You can find the 2026 SOSA here.
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 quickly if we are to reliably meet growing demand for electricity from communities across the country.
We have developed a 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.
