Publisher

PUDL's source page describes FERC Form 1 as a comprehensive financial and operating report submitted annually by major electric utilities, licensees and others, and says new XBRL filings are added to FERC's RSS feed on a rolling basis.docs.catalyst.coop/pudl/en/v2026.9.0/data_sources/ferc1.html ↗

Delay

PUDL's source page states that annual responses are due in April of the following year and that revisions and late filings typically continue to trickle in for months after the filing deadline. The tables' last report year is the one stated under coverage.docs.catalyst.coop/pudl/en/v2026.9.0/data_sources/ferc1.html ↗

This atlas

The atlas reads FERC Form 1 through PUDL, which Catalyst Cooperative publishes as quarterly versioned releases. Each atlas release pins one PUDL version, named under edition; the tables change only when that pin moves. No timed refresh.docs.catalyst.coop/pudl/en/v2026.9.0/data_access.html ↗
