out_gridpathratoolkit__hourly_available_capacity_factor
Hourly time series of capacity factors defining the capacity available from an aggregated group of generators.
- Most-recent data:
2021
- Processing:
Data is ready for use in analyses, but for practical reasons has not been denormalized and remains in narrow format.

Usage Warnings
Contains estimated values.
The original data is no longer being collected or reported in this way.
Additional Details
This table contains a mix of profiles representing whole regions and individual plants, where the individual plants are hybrid wind or solar plus electricity storage facilities. Capacity factors are stated as a fraction of the aggregate nameplate capacity of the group.
For the hybrid facilities, the capacity factor represents the available output of only the renewable generators. Estimates of the generation profiles have been extended across a longer range of dates than the original data. For wind, the years 2015-2020 are synthesized data and for solar 2020 is synthesized. See the Appendix of the GridPath Resource Adequacy Toolkit report for details.
Columns
Date and time converted to Coordinated Universal Time (UTC).
A label identifying a group of aggregated generator capacity factors.
Fraction of potential generation that was actually reported for a plant part. Energy generated over time period / nameplate capacity * time period (hours/years/etc.).
core_gridpathratoolkit__assn_generator_aggregation_group
Association table providing connections between individual generator IDs and their corresponding aggregation group when creating aggregated profiles.
- Processing:
Data has been cleaned and organized into well-modeled tables that serve as building blocks for downstream wide tables and analyses.

Additional Details
This table defines which individual generator profiles are combined when creating aggregated capacity factors / generation profiles. Generator capacity is used to weight the contribution of each generator in the resulting aggregated profiles, and is made available in this table for convenience and legibility. The resulting aggregated profiles are stored in out_gridpathratoolkit__hourly_available_capacity_factor.
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!
A label identifying a group of aggregated generator capacity factors.
Total installed (nameplate) capacity, in megawatts.
Every row in the aggregation table describes a single generator. Groups of rows with the same aggregation are combined using a capacity weighted average to produce an aggregate generation profile. A few generators are not included in that aggregation process. This column determines whether a generator is included.
