* Note: Data as of August 8, 2017


** Note: The Direct Coal Imports category is based on reported ownership shares and contractual arrangements for power purchases by California utilities. Only Utah's Intermountain Power Project and Nevada's Mohave Generation Station (shut down as of 2006) are included as Direct Coal Imports.


*** Note: Electric generation from all out-of-state power plants is counted as an import. Four California Balancing Authorities report annual electric generation imports and exports to the Energy Commission: California Independent System Operator, Los Angeles Department of Water and Power, Imperial Irrigation District, and Balancing Area of Northern California. There are currently 18 out-of-state power plants that are considered to be electrically within one or more of these Balancing Authorities' control areas. These include: Agua Caliente Solar, Arlington Valley Solar, and Mesquite Solar in Arizona; Baja Mexico Wind, Termoelectrica de Mexicali Plant, and InterGen's La Rosita Plant (natural gas) in Mexico; Milford Wind and Intermountain Power Plant (coal) in Utah; and Mohave Generation Station (coal), Terra-Gen Dixie Valley (geothermal), Desert Star (natural gas), Copper Mountain Solar, and Silver State Solar, all located in Nevada.
