Regional Energy Transition Accelerator Map

The Regional Energy Transition Accelerator (RETA) Map is an information resource for decision-makers, engineers and analysts involved in the energy transition of large, fossil-fuelled, stationary heat users in New Zealand.

The dashboard provides information about important energy demand sites and key energy supply and infrastructure locations. It also contains the results of the RETA reports, to provide a broad visual picture of future electricity and biomass demands and availability, region-by-region.

Note this map may take a few seconds to load.

Last updated: June 2025

An interactive tool that is a visual representation of important demand and supply side energy sites, with a regional focus.

About the data

The information presented in the dashboard is based on data from a range of private and publicly available datasets (including from electricity distribution businesses, Transpower, forestry, sawmills, and process heat users), and on analysis carried out during the RETA programme.

A full description of the methodology used, assumptions made, data sources and references is contained in each of the individual RETA reports. Explanations of key terms and concepts used in the analysis is also available in the Help section of the dashboard.

How to use this tool

There are three tabs/views available:

Shows the location of the process heat demand sites along with key energy supply and infrastructure locations identified during the RETA programme and provides summary information about each site.
- Pan or zoom to a specific area or region in the map.
- ‘Layers’, on the left of the screen, allows the user to toggle visible layers on and off by clicking the small square next to the layer name.
- ‘Legend’ shows the symbols used to categorise the process heat sites shown on the map. Sites are categorised by whether the projects identified are confirmed (ie. completed or have committed funding) or unconfirmed, and by the size of site energy demand (TJ/year).
- To select an individual site, click on the site location bubble. Information about that site will appear in the panel to the right of the map.
- Hover over the 'i' help icon for more explanation or go to the Help dropdown.
Presents information about the potential availability of and future demand for biomass for process heat in a region.
- Select the region to view from the drop-down menu at the top-left.
- There are four tabs containing information on forecast wood availability, estimated in-forest residues, biomass available for bioenergy, and future biomass demand and availability.
- Information on the data presented and the source of the date is provided on each screen.
Shows the potential pathways by which process heat use could switch from fossil fuels to either electricity or biomass within a region.
- Select the relevant region from the drop-down menu at the top-left.
- There are four tabs containing graphs that show the change in fossil fuel use and new electricity and biomass demand under different scenarios, as well as the potential process heat emissions reductions.
- Information on the scenarios used to develop the pathways and the methodology applied is provided in the Help dropdown.
- A link below the graph enables the data to be exported to a CSV file.
