This visualization shows the annual net electricity generation in Northwest in 2022 and the energy resources used by each generator.

Hydroelectric power provides the largest share of electricity generation in the Northwest, though other resources such as natural gas and coal are also used. Hydroelectric power generation can fluctuate due to differences in annual snowpack and precipitation. When there is a shortfall in hydroelectric generation, natural gas fuel is typically used instead.  

While the Northwest Electricity Capacity map shows the generator’s nameplate capacity, this visualization shows the net electricity that was actually produced by each of these generators in 2022, measured in megawatt hours (MWh). Net electricity generation can be negative if a resource consumes power but does not produce any energy, such as batteries.

Each circle on the map represents an electricity generator and is color-coded to show the resource type used. The circle size represents the annual net generation. Filter by resource type by clicking on it in the list below the map.

Note: Keep in mind that the scale adjusts when a filter is applied. The resulting scale is relative to the other elements within that filter and is shown in the legend on the right.
