The Forms’ data available for download on this page results from converting the data in historical filings originally submitted in Visual FoxPro (VFP), prior to October 1, 2021, to XBRL by applying the first XBRL taxonomy. This is FERC staff’s best estimation of what the filing would have been had it been formatted according to the first taxonomy. These are XBRL instance (submission) files created from the historic VFP data, and are duplicates of what can be found in the eForms Portal after October 1, 2021. These files can be used to build an XBRL database for FERC Form Nos. 1, 1-F, 2, 2-A, 3-Q electric, 3-Q natural gas, 6, 6-Q, 60, and 714.
Currently this data is limited to Q3-2011 to Q4-2020 but will be updated to include Q1-2021 and Q2-2021 by the end of 2021.
