As provided for in the July 17, 2020 Order on Technical Conference, notice ( printed page 16592) is hereby given that on April 15, 2021, the eXtensible Business Reporting Language (XBRL) taxonomies, validation rules, and rendering files needed to file FERC Form Nos. 1, 1-F, 3-Q (electric), 2, 2-A, 3-Q (natural gas), 6, 6-Q (oil), 60, and 714 (collectively, Commission Forms),^[1] will be updated to Release 1.5.^[2] The updated taxonomies will be available in the Yeti viewer at https://xbrlview.ferc.gov/​.^[3] The updated validation rules and rendering files will be available at https://www.ferc.gov/​ferc-online/​ferc-online/​filing-forms/​eforms-refresh. The eForms system will incorporate the updated (Release 1.5) taxonomies, validation rules, and rendering files and use them to process filers' test-only submissions in May 2021. In addition, as noted below, the deadlines for submitting the third quarter 2021 filings of FERC Form Nos. 3-Q (electric), 3-Q (natural gas), and 6-Q (oil) are extended until December 31, 2021.

The updated (Release 1.5) taxonomies, validation rules, and rendering files will become effective beginning with the third quarter 2021 filings of FERC Form Nos. 3-Q (electric), 3-Q (natural gas), and 6-Q (oil). The current Visual FoxPro-based system for filing Commission Forms will no longer be available for submissions after September 30, 2021. Therefore, all subsequent filings and any future refilings, i.e., all post-September 30, 2021 filings and refilings, of the FERC Form Nos. 3-Q (electric), 3-Q (natural gas), and 6-Q (oil) and the other Commission Forms ( i.e., FERC Form Nos. 1, 1-F, 2, 2-A, 6, 60, and 714) must be made using the applicable taxonomies, validation rules, and rendering files for the relevant form, as indicated on the eForms portal.
