# Raw FERC Form 1 Data Dictionary We have mapped the Visual FoxPro DBF files to their corresponding FERC Form 1 database tables and provided a short description of the contents of each table here. #### NOTE * The mapping of File Name to Table Name is consistent across all years of data. * Page numbers correspond to the pages of the FERC Form 1 PDF as it appeared in 2015 and may not be valid for other years. * Many tables without descriptions were discontinued prior to 2015. * The “Freq” column indicates the reporting frequency – A for Annual; Q for Quarterly. A/Q if the data is reported both annually and quarterly. #### NOTE As of 2025-09-08 the links below are not working, because we are in the process of migrating web-based access to PUDL data to [a new interface](https://data.catalyst.coop).
