Annual Generation - Plant Unit

Column Key for Annual Generation by Plant Unit:

Category: Broad classifications for power plants:

• G = Natural Gas
• S = Solar
• T = Geothermal
• N = Nuclear
• C = Coal
• E = Biomass
• H = Hydro
• W = Wind

Year (second column): Use the small "^" and the "v" beside the current year showing to view other years. For most datasets, the oldest year will be 2001.

Plant ID: The CEC Plant ID is a unique identifier used by the Cartography Unit to track power plants.

Plant Name: The name given for the plant by the company owner. May be different from other common references in use in other proceedings, hearings, etc.

Unit: The name given to track a specific generating unit within the power plant.

Status: Refers to the current operating status of the generating unit:

• IS = Indefinite Shutdown
• RE = Retired
• OP = Operating
• SB = Standby
• MR = Maintenance
• UNK = Unknown (it happens from time to time)

Start Date: Date the generating unit went into commercial operation.

Retire Date: Date the generating unit was permanently removed from commercial operation

Prime Mover ID: The type of engine or turbine that is the source of power for driving the generator:

• ST = Steam Turbine, not part of a combined-cycle plant
• GT = Combustion Gas Turbine, not part of a combined-cycle plant
• CT = Combustion Turbine portion of a combined-cycle plant
• CA = Steam Turbine portion of a combined-cycle plant
• CS = Single shaft combined-cycle unit
• HY = Hydroelectric generator
• IC = Internal Combustion generator
• FC = Fuel Cell
• PV = Photovoltaic (Solar)
• OT = Other (typically heat recovery systems used in petroleum refinery operations)
• WT = Wind Turbine

Prime Mover Description: See above.

Capacity: Nameplate capacity as reported by the power plant owner.

County: The physical county the power plant is located in. May include non-California counties.

Net MWh: Total energy produced by the unit for the given year in megawatt-hours.

Primary Fuel Use (MMBtu): Total primary fuel consumed by the unit in a year as measured in MMBtu.

Primary Energy Source: Primary fuel type used by the generating unit. See below for Key:

Secondary Fuel Use (MMBtu): Total secondary fuel consumed by the unit in a year as measured in MMBtu.

Secondary Energy Source: Secondary fuel type used by the generating unit: See above for Key.

NOTE: The information in the following table can be copied to a spreadsheet program such as MS Excel by highlighting the desired records and then copying and pasting them into a spreadsheet. A single spreadsheet download option is not provide since there are multiple years of data available. The source "txt" files are available for download and can be used in a spreadsheet program such as MS Excel or imported into a database application such as MS Access.
