Load by operational zone

The New Zealand power system is split into 14 operational zones. The graphic on this page displays loads in each operational zone, as taken from the System Operator's SCADA system. Combined, these values represent total power demand across the country.

SCADA is the System Operator's primary tool for controlling the transmission network and is the source of critical information for the electricity market system as well as for local lines companies.
