Notes:

1 This number only includes generator-reported electricity, not electricity produced by many small-scale photovoltaic installations throughout the state.
Based on the the Energy Commission's Renewable Energy Program records, the state has financed approximately 135,517 kilowatts (kW) of solar photovoltaic capacity.
Assuming that each installed kW of PV-generated 1,500 kWh in 2005, then the combined output of these PV systems would add another 203.3 gigawatt-hours to the gross system power totals.

2 The in-state coal-fired generation includes electricity generated from several out-of-state coal-fired power plants that are owned by and reported by California utilities. There are other out-of-state generation facilities that are owned by California utilities, which are reported as imports.

Generally, to convert from gigawatt hours into megawatts, divide the number of gigawatts by 8,760 then multiply by 1,000 to get megawatts. This is "average" megawatts, as capacity of power plants varies depending on resource/fuel type and plant efficiency.
