| Source Description              | Hourly renewable generation profiles compiled for the Western United States as part of the GridPath Resource Adequacy Toolkit. Profiles are stated as a capacity factor (a fraction of nameplate capacity). There are 3 different levels of processing or aggregation provided, all at hourly resolution: Individual plant (wind) or generator (solar) output, capacity-weighted averages of wind and solar output aggregated to the level of balancing authority territories (or transmission zones for larger balancing authorities), and that same aggregated output but with some problematic individual generator profiles modified such that they match the overall production curve of the balancing authority they are within. This data also contains some daily weather data from several sites across the western US and tables describing the way in which individual wind and solar projects were aggregated up to the level of balancing authority or transmission zone. |

## PUDL Database Tables

We’ve segmented the processed data into the following normalized data tables.
Clicking on the links will show you a description of the table as well as
the names and descriptions of each of its fields.

## Background

The [GridPath RA Toolkit](https://gridlab.org/gridpathratoolkit/) was created through a collaboration
between [GridLab](https://gridlab.org),
[Moment Energy Insights](https://www.momentenergyinsights.com/)
and [Blue Marble Analytics](https://www.bluemarble.run/).
It supports resource adequacy analysis for the Western United States, improving the
characterization of three phenomena that will be increasingly important for
understanding resource adequacy in future power systems: weather-driven relationships
between load and resource availability; capabilities and constraints of energy limited
resources; and transmission flows and regional coordination.

The Toolkit leverages publicly available data and the
[GridPath](https://www.gridpath.io/) open-source power system modeling platform.
To demonstrate the effectiveness of the Toolkit, a Western US 2026 resource adequacy
analysis case study was developed. The GridPath RA Toolkit refers to both the datasets
and the algorithms that were developed to support the 2026 Western US case study. With
the support of GridLab, Catalyst has integrated datasets focusing on the hourly
availability of wind and solar resources into PUDL under a
[CC-BY-4.0](https://creativecommons.org/licenses/by/4.0/) license.

### Data available through PUDL

Initially, PUDL has only integrated the most processed version of the wind and solar
generation profiles. These profiles are aggregated to the level of transmission zones,
and extended with synthetic data to cover the period from 1998-2020. The wind data for
2015-2020 and the solar data for 2020 are synthetic.

Hybrid generators which have associated battery storage are broken out individually,
with the hourly capacity factors representing just the renewable portion of the
facility’s generation.

We have also integrated the tables which describe which individual plants and generators
were aggregated in each group, so that users can programmatically access related data
in other PUDL tables based on the EIA plant and generator IDs.

### Who submits this data?

This data does not come from a government agency, and is not the result of compulsory
data reporting.

### What does the original data look like?

We have archived the original GridPath RA Toolkit renewable generation profile data
[on Zenodo](https://doi.org/10.5281/zenodo.10844661). This is a manually compiled
archive, because the source data is not being updated, and not all of the data included
in the original release can be redistributed under an open license.

The original data was published as a collection of CSV files. In many cases each CSV
contains a capacity factor time series for a single transmission zone or generator,
with the name of the file indicating what transmission zone or generator the data
pertains to. The timestamps associated with those records are typically stored in a
separate standalone CSV file, with the data and time index being aligned based on row
number.

The archive contains data at 3 different levels of processing and aggregation. Thus far
we have only integrated the most processed, most immediately usable version. For more
detail on the processing techniques see the Appendices of the [GridPath RA Toolkit
report](https://gridlab.org/gridpathratoolkit/)

The least processed version includes modeled hourly capacity factors for individual wind
and solar resources, at the plant level for wind and the generator level for solar.
With thousands of individual generators and data spanning multiple decades this data
contains hundreds of millions of records.

These profiles are aggregated to the level of transmission zones, weighted by the
nameplate capacity of each facility.

The data is then extended with synthetic data so that both the wind and solar data cover
the same time period. The wind data for 2015-2020 is synthetic, as is the solar data
from 2020. This is currently the only capacity data that has been integrated into PUDL.

## Notable Irregularities

We are still in the early stages of integrating the GridPath RA Toolkit data into PUDL.
This section will be updated as we learn more about the particularities of this dataset.

## PUDL Data Transformations

To see the transformations applied to the data in each table, you can read the
docstrings for [`pudl.transform.gridpathratoolkit`](../autoapi/pudl/transform/gridpathratoolkit/index.md#module-pudl.transform.gridpathratoolkit) created for each table’s
respective transform function.
