The hydroelectric marker for Grand Coulee Dam is not to scale. It should be larger. If drawn to scale it would dwarf the nearby markers.

According to the overview, the map does not include small producers in order to limit the number of markers. For the following sources, only producers above the specified cutoffs are shown:

• Hydropower: above 5 MW (Idaho) or 20 MW (other)
• Natural Gas & Wind: above 10 MW
• Biomass: above 1 MW
