* Note: The data in this table is based on corrections and updates as of August 1, 2012.
** Note: The "Direct Coal Imports" category is based on reported ownership shares and contractual arrangements for power purchases by California utilities. Due to legislative changes required by Assembly Bill 162 (2009) and to simplify the characterization of coal power generation, only Utah's Intermountain Power Project and Nevada's Mohave Generation Station (closed as of 2006) are included in the reported "Direct Coal Imports" for 1997 through 2011 on this table. A more detailed analysis of the role of coal-based power generation within California is outside the scope of this table. The California Air Resources Board is currently undertaking the task of identifying the fuel source of all imported power into California. When comparing coal and other power imports over time, the best approach is to compare the combined value of both "Direct Coal Imports" and "Other Imports."
*** Note: In this tabulation, generation located physically out-of-state is included in the energy imports category. The energy imports and exports include all electricity flows in and out of the state as reported by four California Balancing Authorities: California Indendent System Operator, Los Angeles Department of Water and Power, Imperial Irrigation District, and Sacramento Municipal Utility District plus generation at five out-of-state power plants that are within one or more of these Balancing Authorities' control areas but are physically located outside California. These plants include Intermountain Power Plant in Utah, Mohave Generation Station in Nevada (now closed), Caithness Dixie Valley Valley Plant in Nevada, Termoelectrica de Mexicali Plant and InterGen's La Rosita Plant both of which are in Mexico. Power generated by these plants are not typically reported on Balancing Authorities control area imports and exports categories, hence their inclusion in this methodology.
