  1. [Docket No. RM19-12-000]

Notice is hereby given that, on March 26, 2026, the eXtensible Business Reporting Language (XBRL) taxonomies, validation rules, and rendering files needed to file the FERC Form Nos. 1, 1-F, 2, 2-A, 3-Q electric, 3-Q natural gas, 6, 60, and 714 [1] will be updated to Version 2026-04-01.[2] Version 2026-04-01 will be effective starting with the first quarter 2026.

The draft updated (Version 2026-01-01) taxonomies, validation rules, and rendering files are currently available for download in the eForms portal ( https://ecollection.ferc.gov) and are available for testing in the eForms portal. Suggestions on the draft Version 2026-01-01 taxonomies can be provided by March 2, 2026 through https://XBRLview.ferc.gov. Version 2026-01-01 includes minor technical improvements to taxonomy and rendering code and incorporates Order No. 898 taxonomy updates for FERC Form No. 60.[3] For FERC Form No. 60, Version 2026-01-01 also includes technical edits to the codesets required for updating to Xule v1.2, Arelle v2.35.18, and the adoption of the XBRL Inline Renderer (XENDR) ( https://xbrl.us/​xule/​xendr/​ ) to render the human readable HTML documents.[4]

The following FERC Form filings due after March 26, 2026 must be filed using the Version 2026-04-01 taxonomies, validation rules, and rendering files: (1) the 2025 FERC Form Nos. 60 and 714 and; (2) the 2026 FERC Form Nos. 1, 1-F, 2, 2-A, 3-Q electric, 3-Q natural gas, and 6. Please see the Taxonomy History page ( https://ecollection.ferc.gov/​taxonomyHistory) for detailed version information organized by form.

Dated: December 16, 2025.

Carlos D. Clay,

Deputy Secretary.

4.  As noticed under Docket No. RM19-12-000, “Notice of FERC Form No. 60 Taxonomy Update” (April 3, 2025), Taxonomy Version 2024-04-01 was used for both the 2023 and 2024 reporting periods for FERC Form No. 60. Because of this, Arelle, Xule, and XENDR dependency updates in the FERC Form No. 60 Taxonomy Package were delayed until this 2026-01-01 draft taxonomy package. All other taxonomies adopted these updates with Version 2025-04-01.
