Supply, the resources available to meet demand, is crucial to the resource adequacy equation. One way to look at resources is nameplate capacity—the amount of electricity a resource can produce in a constraint-free world. Resources typically do not produce at their nameplate capacity due to things like weather, temperature, fuel supply, equipment failures, and age. However, nameplate capacity is useful in understanding the resource portfolio of an area.
By selecting separate regions from the map, you can see specific trends associated with the different subregions within the Western Interconnection. Different combinations of BAs can be selected from the drop-down chart.
Note: When a subregion is selected from the map, the list of BAs in the drop-down list corresponds to the BAs in that region. If there are selections in the BA list, only the regions of the map with a BA in the list are selectable.
To reset the map, select the highlighted region a second time. To reset the BA list, either “x out” of the BA(s) selected or hit the eraser button.
