Power system loads in the South Island north of Waitaki Valley (Zone 3) are displayed on this page to give power companies loading information across the zone.
This information is updated every five minutes. Due to the location of recording equipment at some sites, the load split between retailers for these zones is indicative only.
The historical Zone Load Peaks are winter and summer seasonal values and are reset at the change of seasons on 20 October and 10 May.
The graph of the previous week’s USI load, VSAT load limit and USI Generation, has been removed. If this information is still required please contact system.operator@transpower.co.nz
