When MPNZ's load shedding percentage exceeds 75%, the bar on the graph should move into a red zone. It signals the USI transmission grid is approaching peak loading and as MPNZ's load shedding percentage approaches 100% there is a reasonable likelihood of new chargeable peak periods occurring.
When the end of the bar is red MPNZ is deploying its maximum load control capability (100%). The longer MPNZ load shedding remains at 100% the more likely new chargeable peak periods will occur on the USI grid. This forms a reasonable signal for consumers to manage their load and to continue doing so until the bar on graph moves down from 100% and ceases to be red at the end.
When the whole bar is white (0%) MPNZ is not controlling any load and the grid will be operating at normal load levels. This bar is updated every 5 minutes.
