California top electricity importer, Pennsylvania top exporterChristian Fernsby ▼ | April 8, 2019
Electricity routinely flows among the Lower 48 states and, to a lesser extent, between the United States and Canada and Mexico.
America Pennsylvania was the largest net exporter of electricity
California was the largest net importer, receiving an average of 77 million MWh annually.
Based on the share of total consumption within each state, the District of Columbia, Maryland, Massachusetts, Idaho, and Delaware were the five largest power-importing states between 2013 and 2017.
Wyoming, West Virginia, North Dakota, Montana, and New Hampshire were the five largest power-exporting states.
States with major population centers and relatively less generating capacity within their state boundaries tend to have higher ratios of net electricity imports to total electricity consumption.
Wyoming and West Virginia were net power exporting states (they exported more power to other states than they consumed) between 2013 and 2017.
Customers residing in these two states are not necessarily at an economic disadvantage or advantage compared with customers in neighboring states.
However, large amounts of power trading may affect a state’s revenue derived from power generation.
Some states also import and export electricity outside the United States to Canada or Mexico.
New York, California, Vermont, Minnesota, and Michigan are the five states that imported the most electricity from Canada or Mexico on average from 2013 through 2017.
Similarly, Washington, Texas, California, New York, and Montana are the five states that exported the most electricity to Canada or Mexico, on average, for the same period. ■
