Who is in this cut

Included: oil and gas producers and oilfield-service contractors, coal and hard-rock mines, refineries and pipelines, electric and gas utilities, power plants, solar and wind manufacturers and installers, and waste, recycling and environmental-services operators.

What counts as energy, mining or utility here: the employer name reads as energy, oil, gas, petroleum, mining, coal, solar, wind, utility, electric, pipeline, drilling, refinery, nuclear, quarry, power plant, well services, oilfield, waste, recycling or sanitation, or is one of ~120 named companies (ExxonMobil, Chevron, Halliburton, Schlumberger, Baker Hughes, Peabody, Arch, Alpha Natural Resources, Duke Energy, PG&E, SunPower, Sunrun, First Solar, Bechtel, Fluor, KBR, AECOM, Waste Management and others). Two boundaries to know before you quote a number: (1) the word electric also catches Schneider Electric (industrial equipment) and Electric Boat (a submarine builder), so a handful of manufacturing notices are in this cut rather than in aerospace/defense or manufacturing — sector_rule = electric marks them; (2) engineering-and-construction firms that build plants (Bechtel, Fluor, Jacobs, AECOM, Kiewit) are here, not in construction, because their WARN filings are overwhelmingly at energy sites. A driller trading under a founder's name reveals no sector and is not here; it is in the unclassified remainder of the sector dataset. Every row keeps the sector_rule that fired.

Why this file exists

Oil-patch and coal-country layoffs move with commodity prices and arrive in waves, county by county, weeks before they show up in any national number. The filings — which mine or field, which town, how many workers, notice date, effective date, closure or layoff — sit on 48 separate state portals and are never assembled as one energy series. This file is that series, with the closure/layoff split the states themselves recorded.

The employers with the most energy, mining and utilities notices on record

Counted per notice, not per event: a company that files in four states files four notices. Employer names are the resolved spelling — the raw agency spelling is kept in the download.

The 15 most recent energy, mining and utilities notices

Date is the notice date where the agency publishes one, otherwise the layoff date. 276 of the 1,281 notices in this cut are recorded as a closure rather than a layoff.

How the industry is decided: no state WARN portal publishes an industry field, so there is no NAICS column to filter on. The sector here is assigned from the resolved employer name by a published rule table (19 sectors, 3,152 patterns, first match wins), and every row carries the pattern that fired in its sector_rule column so you can audit or re-cut it. The archive holds 61,428 notices; 61,232 of them carry a usable date and are in the sector file (196 have no date in either column), 32,168 come out with a sector, and 29,064 stay unclassified — and are still counted in every total shown anywhere on this site. Manual audit 2026-09-12: 4 of 60 sampled rows were assigned to the wrong sector. Rebuilt 2026-09-24.

How to check any of this

Every number on this page is computed at build time from notices_by_sector.csv (one row per notice, with the sector and the rule that assigned it), and the yearly series from sector_by_year.csv. The free HTTP API serves the whole archive as JSON, NDJSON and per-state CSV with no key. This industry is also published as its own Hugging Face dataset, and the full sector cut as one file. If a number here disagrees with the file, the file is right and it is a bug — tell us and it is fixed the next morning.
