core_eia__entity_generators
Return to SearchEntity table containing static information about generators compiled from across the EIA-860 and EIA-923.
- Processing:
Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.
- Source:
EIA -- Mix of multiple EIA Forms
- Primary key:
plant_id_eia, generator_id
Usage Warnings
Data has been drawn from several EIA sources which are not always consistent with each other, and PUDL chooses the most consistent or relevant value to facilitate cross-referencing even if that means some values will differ from the raw sources. See Harvesting for details, and see Entity Resolution Methodology for a fuller conceptual overview.
Contains information from multiple raw inputs.
Additional Details
This is one of two tables where canonical values for generators are set. It contains values which are expected to remain fixed, while core_eia860__scd_generators contains those which may vary from year to year. EIA reports many attributes in many different tables across EIA-860 and EIA-923. In order to compile tidy, well-normalized database tables, PUDL collects all instances of these values and and chooses a canonical value. By default, PUDL chooses the most consistently reported value of a given attribute as long as it is at least 70% of the given instances reported. If an attribute was reported inconsistently across the original EIA tables, then it will show up as a null value. See /methodology/entity_resolution for a conceptual overview of this process. All tables downstream of this one inherit the canonical values established here.
Columns
The unique six-digit facility identification number, also called an ORISPL, assigned by the Energy Information Administration.
Generator ID is usually numeric, but sometimes includes letters. Make sure you treat it as a string!
Indicates whether the unit has duct-burners for supplementary firing of the turbine exhaust gas
Date the generator began commercial operation. If harvested values are inconsistent, we default to using the most recently reported date.
If the generator is associated with a combined heat and power system, indicates whether the generator is part of a topping cycle or a bottoming cycle
Indicates whether the generator is part of a solid fuel gasification system
Indicates whether the generator uses pulverized coal technology
Indicates whether the generator uses fluidized bed technology
Indicates whether the generator uses subcritical technology
Indicates whether the generator uses supercritical technology
Indicates whether the generator uses ultra-supercritical technology
Indicates whether the generator uses stoker technology
Indicates whether the generator uses other combustion technologies
Can this generator operate while bypassing the heat recovery steam generator?
The designation used to identify the price node in RTO/ISO Locational Marginal Price reports
The designation used to report the specific location of the wholesale sales transactions to FERC for the Electric Quarterly Report
Indicates whether the generator is associated with a combined heat and power system
The date the generator was originally scheduled to be operational
Indicates whether a fuel switching generator can switch fuels while operating.
Indicates whether the generator was previously reported as indefinitely postponed or canceled
