California's electricity imports in 2019
California has large energy resources and is among the top producers of oil, hydroelectricity, solar, biomass, and geothermal energy in the United States. However, California also imports a significant amount of electricity from other states. In 2019, California's net electricity imports were the largest in the country, at 70.8 million megawatt-hours (MWh), or 25% of the state's total electricity supply. This made California the largest net electricity importer of any state in 2019.
California's electricity imports come from a variety of sources and locations. The state's investor-owned utilities were transitioning to time-of-use pricing in 2019, with 30.1% of electricity imported as of 2021 (11.7% from the Northwest and 18.4% from the Southwest), including 30.9% from renewables. California utilities partly owns and imports power from several power plants in Arizona and Utah. The state also imports hydroelectric power from the Pacific Northwest, particularly across high-voltage transmission lines running from Oregon to the Los Angeles area. Additionally, California receives electricity from outside the United States, with Mexico and Canada being trade partners.
California's high electricity demand and lack of local power plants contribute to its need to import electricity. Natural gas-fired power plants typically account for almost half of in-state electricity generation, and the state has set ambitious goals for increasing the use of renewable energy sources. In 2006, the California legislature passed the Global Warming Solutions Act, aiming for 33% of electricity consumption to be generated by renewable sources by 2020. This target was further increased in subsequent years, with Senate Bill 100 passed in 2018 requiring 50% renewables by 2026, 60% by 2030, and 100% by 2045.
California's electricity rates are among the highest in the United States, partly due to the changing energy mix, including the construction of new natural gas power plants. As of 2021, California's electricity costs were 19.7 cents per kWh. The state has also experienced challenges in meeting peak electricity demand, with widespread rolling blackouts narrowly avoided during a September 2022 heatwave. California's plan to decarbonize its economy by 2045 will further increase electricity consumption, requiring up to 70% more electricity compared to 2022 to decarbonize sectors reliant on fossil fuels.

Electricity imports from the Northwest and Southwest
California has large energy resources and is among the top producers of oil, hydroelectricity, solar, biomass, and geothermal energy in the United States. However, the state also has a high electricity demand and a lack of local power plants, which means it imports more electricity than any other state. In 2018, 32% of its consumption was imported, and in 2019, California's net electricity imports were the largest in the country at 70.8 million megawatt-hours (MWh) or 25% of the state's total electricity supply.
California's electricity imports come from the Northwest and the Southwest. The Northwest category is made up of Alberta, British Columbia, Idaho, Montana, Oregon, South Dakota, Washington, and Wyoming. The Southwest category includes Arizona, Baja California, Colorado, Mexico, Nevada, New Mexico, Texas, and Utah. In 2021, electricity imports from the Northwest and Southwest remained at similar levels to 2020, accounting for approximately 30% of total system electric generation.
California's electricity imports from the Northwest include hydroelectric power, which is transmitted across high-voltage transmission lines running from Oregon to the Los Angeles area. In 2021, total hydroelectric generation, including imports, fell by 23% to 28,490 GWh from 37,023 GWh in 2020. This decrease was due to a record-breaking heatwave in June, which resulted in a fast snowmelt and reduced hydroelectric availability in the summer when California typically imports energy to meet air conditioning loads.
California's electricity imports from the Southwest include nuclear, coal, and natural gas-fired production from the desert. In 2021, imports from the Southwest increased by 2.5% due to a shift in energy imports from the Northwest to the Southwest, which helped maintain overall imports into California at similar levels to 2020.

California's net electricity imports
California has large energy resources, ranking among the top producers of oil, hydroelectricity, solar, biomass, and geothermal energy in the United States. However, California's electricity rates are among the highest in the country, at 19.7 cents per kWh as of 2021. This is due to the changing energy mix within the state, including the aggressive construction of new natural gas power plants. California also has a high electricity demand, and a lack of local power plants, which means it imports more electricity than any other state.
In 2018, California imported 32% of its electricity consumption, primarily wind and hydroelectric power from states in the Pacific Northwest, and nuclear, coal, and natural gas-fired production from the desert Southwest. In 2019, California's net electricity imports were 70.8 million megawatt-hours (MWh), or 25% of the state's total electricity supply. This made California the largest net electricity importer of any state that year. In 2021, electricity imports accounted for approximately 30% of total system electric generation in California.
California's investor-owned utilities transitioned to time-of-use pricing in 2019 and 2020. In 2021, 30.1% of electricity was imported (11.7% from the Northwest and 18.4% from the Southwest), with 22.6% of unspecified origin and 30.9% renewables. In 2022, imports from the Northwest and Southwest remained at similar levels to 2021.
California's legislature has resisted allowing more connections to other states for fear of losing sovereignty over the state's electricity supply. However, experts state that more grid connections would allow California to export excess solar and wind-generated electricity to other states, and import wind-generated electricity from other Western states.

California's electricity exports
California has large energy resources, ranking among the top producers of oil, hydroelectricity, solar, biomass, and geothermal energy in the United States. However, the state also imports a significant portion of its electricity from other states and, to a lesser extent, Canada and Mexico. In 2019, California was the largest net electricity importer of any state in the country, with net electricity imports of 70.8 million megawatt-hours (MWh), or 25% of the state's total electricity supply. This figure had increased from an average of 89 million MWh annually between 2013 and 2017. California's electricity imports primarily consist of wind and hydroelectric power from states in the Pacific Northwest and nuclear, coal, and natural gas-fired production from the desert Southwest.
California's high level of electricity imports can be attributed to several factors. Firstly, the state has a high electricity demand due to its large population and economically significant industries. Additionally, California has relatively few local power plants compared to other states, which contributes to its reliance on imported electricity. The state's energy mix is also changing, with a shift towards more expensive natural gas power plants and a focus on transitioning to renewable energy sources. As a result, California's electricity rates are among the highest in the United States.
California's electricity imports can come from both within the United States and internationally. From 2013 to 2017, California was the state that exported the most electricity to Canada and Mexico, on average, during that period. Within the United States, electricity flows between the Lower 48 states, with some electricity also being transmitted across state lines. Pennsylvania, for example, was the largest net exporter of electricity between 2013 and 2017, sending an annual average of 58 million MWh outside the state.
While California is a net importer of electricity, it does have the capacity to generate a significant amount of electricity from various sources. As of 2018, the state had 80 GW of installed generation capacity, encompassing more than 1,500 power plants. Natural gas-fired power plants typically account for almost half of in-state electricity generation, while California is also one of the largest hydroelectric power producers in the country. Renewable energy sources, such as solar and wind, are also a growing part of California's energy mix, with the state setting ambitious goals for increasing its renewable energy consumption.
