Historical Grid Demand Dataset

I have been looking through the forum and various Azure links to see if there is an easy way to get the demand data from this report: https://www.emi.ea.govt.nz/Wholesale/Reports/W_GD_C. I'm interested in hourly actual demand data by region. The closest thing I found in the wholesale datasets is the grid export, which I saw from another forum post that it is not the same as demand. 

Additionally, on the report link, there is an option for "Zone" in the regions. Is there a map somewhere that lays out which regions fall in those zones? For example, which regions (Northland, Auckland, etc) make up Upper North Island, etc?


Thanks in advance,

Hi Daisy,

Here's a link to the Electricity Networks Association website - there you will find a map of NZ with the different electricity networks.  I recommend segmeting by network region.

There are also GIS map data on the EMI portal - as well as a schedule of grid exit points and the networks and GPS locations.

Cheers, Malcolm

FYI, there's also an NSP table report under Wholesale reports on EMI.
