U.S. electricity generation: electric utilities 2004-2018

Electric utilities in the United States generated approximately 2.33 billion megawatt hours of electricity in 2018. Overall, electricity generation in the United States has been slowly decreasing over the past decade.

Electricity from neighboring countries

Imports of electricity from Mexico and Canada have increased as domestic electricity generation in the United States has decreased. The United States has long exported larger quantities of electricity from Canada, but in recent years imports from Mexico have risen drastically. Electricity imports to California are driving higher imports overall due to the state’s high consumption.

Blackouts and bankruptcy

California has one of the lowest in-state supplies of electricity in the country, despite having some of the largest electric utilities companies. Pacific Gas and Electric (PG&E), the second-largest electric utility in the state, is an investor-owned company that recently filed the largest bankruptcy of any utility company in U.S. history after facing lawsuits for deadly wildfires in 2018. In the fall of 2019, PG&E made major news again for imposing rolling blackouts in California to prevent wildfires as well as decrease the company’s liability.
