Peabody Energy Corp was the largest U.S. coal producer in 2023, mining 104.3 million short tons — 18.0% of total U.S. output — according to Table 10 of the EIA’s Annual Coal Report. Arch Resources Inc followed at 75.3 million short tons (13.0%), and Navajo Transitional Energy Co placed third at 45.7 million short tons (7.9%). Together, the eight largest producers accounted for 64.7% of all U.S. coal mined that year.

That single sentence is the answer most searches for this list actually want. The rest of this page breaks down where each company mined, how the ranking is built, why the “top 8” cutoff exists in EIA’s own methodology, and how coal production numbers link to satellite-based mineral exploration work relevant to mining operators today.

The EIA’s 2023 Top 8 Major U.S. Coal Producers — Full List

Every year, the U.S. Energy Information Administration publishes Table 10 in its Annual Coal Report, ranking domestic producers by short tons mined. For the 2023 reporting year, the confirmed figures from that table are:

1. Peabody Energy Corp — 104.3 million short tons (18.0% of U.S. total)
2. Arch Resources Inc — 75.3 million short tons (13.0%)
3. Navajo Transitional Energy Co (NTEC) — 45.7 million short tons (7.9%)
4. Alliance Resource Partners LP — 34.877 million short tons
5. ACNR Holdings Inc — 32.178 million short tons
6. CONSOL Energy Inc — 26.377 million short tons
7. NACCO Industries Inc — 23.640 million short tons
8. 8th producer — see note below

Positions 1 through 7 above are drawn directly from the source PDF and are not in dispute. For the exact 8th-ranked company and its tonnage, the safest move is to open the table yourself: EIA Annual Coal Report, Table 10 (PDF) lists all 21 major producers in descending order, with tonnage and percentage share in adjacent columns. We’re not going to print a rounded guess where EIA prints an exact number — if you need the 8th line item confirmed to three decimal places, that PDF is the primary source and takes thirty seconds to scan.

What EIA’s Table 10 Actually Measures

Table 10 in EIA’s Annual Coal Report is titled “Major U.S. Coal Producers” and it measures one thing only: short tons of coal actually mined by each company in the calendar year, aggregated across every mine that company operates. It does not measure reserves, mine count, employee headcount, revenue, or export volume — those live in other EIA tables (reserves in Table 15, employment and productivity in Table 8, exports in the EIA’s international coal data series).

This distinction is why “major U.S. coal producers” and “largest coal companies by revenue” or “largest coal reserve holders” can produce different rankings. A company with fewer, larger surface mines in the Powder River Basin can out-tonnage a company running more numerous underground longwall operations in Appalachia, even if the Appalachian producer’s coal sells for a higher price per ton because it’s metallurgical grade rather than thermal.

EIA classifies a producer as “major” once it clears a minimum annual tonnage threshold; below that line, output rolls up into an “other producers” category rather than being listed by name. That’s also why the top 21 named producers — not just the top 8 — cover the vast majority of national output, and everything below them is a long tail of smaller operators.

• Output spans thermal coal for utility power generation and metallurgical coal for steelmaking
• Try it: Enter values above to calculate.

Arch Resources Inc

• 75.3 million short tons in 2023 — 13.0% share, second-largest producer nationally
• Major presence in the Powder River Basin and Illinois Basin, plus Appalachian metallurgical coal operations
• Known for low-sulfur thermal coal alongside a growing metallurgical (coking coal) segment aimed at steel markets

Navajo Transitional Energy Co (NTEC)

• 45.7 million short tons in 2023 — 7.9% share, third-ranked producer
• Operates on and around Navajo Nation lands, with mining activity spanning New Mexico, Wyoming, and Montana
• Distinct ownership structure among the top producers: NTEC is wholly owned by the Navajo Nation, which ties its production decisions directly to tribal economic and reclamation priorities

Alliance Resource Partners LP

• 34.877 million short tons in 2023, ranking 4th
• Primary operations in the Illinois Basin, with additional Appalachian mining
• Structured as a publicly traded limited partnership, distinct from the corporate structures of Peabody and Arch

ACNR Holdings Inc

• 32.178 million short tons in 2023, ranking 5th on Table 10

CONSOL Energy Inc

• 26.377 million short tons in 2023, ranking 6th
• Appalachian operations built around longwall mining, historically export-oriented

NACCO Industries Inc

• 23.640 million short tons in 2023, ranking 7th

Comparative Ranking Table: Tonnage, Share, and Region

Shares marked with “~” are calculated by dividing each company’s tonnage by total 2023 U.S. production implied by Peabody’s confirmed 18.0% share on 104.3 million tons (≈579.4 million short tons total); EIA’s published percentage figures for ranks 4 through 8 were not directly available in the source material reviewed for this piece. Ranks 1 through 3 use EIA’s own published percentages. For any figure you plan to cite in a report, pull the exact percentage directly from Table 10 rather than relying on a derived estimate.

Market Concentration: Top 8 vs. Top 21 vs. Everyone Else

The concentration story is the part a quick AI summary tends to flatten. In 2023, the top 8 major U.S. coal producers combined for 64.7% of total national output. Expand the list to the top 21 major producers — EIA’s full named tier — and combined share rises to 85.4%. That means the remaining roughly 14.6% of U.S. coal production is split across dozens of smaller operators, each below EIA’s threshold for individual naming in Table 10.

Put another way: adding 13 more companies to the list (ranks 9 through 21) only adds 20.7 percentage points of market share, while the top 3 alone — Peabody, Arch, and Navajo Transitional — already account for 38.9%. That’s the shape of a concentrated industry with a long tail: a handful of companies run the large-scale surface mining operations in basins like Powder River and Illinois, while the tail is made up of smaller underground and regional operators, many in Appalachia.

How to Check Next Year’s List Yourself

This ranking will not stay static — coal companies merge, wind down mines, or shift output between basins year to year, and EIA re-ranks the field annually. Here is the durable method for verifying the current list rather than trusting any single year’s snapshot, including this one:

1. Go to the source table directly. EIA republishes Table 10 as part of its Annual Coal Report at eia.gov/coal/annual/pdf/table10.pdf. The URL structure has stayed stable across report years; if the direct PDF link changes, EIA’s annual coal data hub is at eia.gov/coal/, which links out to the current report.
2. Check the release timing. EIA typically publishes the full Annual Coal Report — including Table 10 — in October or November of the year following the reporting period. So the 2023 data in this article was released in the report EIA issued in late 2024; a future year’s data follows the same lag.
3. Use quarterly data to bridge the gap. If you need a directional read before the annual report lands, EIA publishes quarterly coal production figures at eia.gov/coal/production/quarterly, though these are less granular by company than the annual Table 10.
4. Cross-check tonnage against share, not just rank. A company’s rank can hold while its tonnage and share both fall, if total U.S. output is shrinking — read the tonnage column, not just the ordinal position, to know whether “top producer” still means what it meant last cycle.

That four-step check is the actual takeaway to keep: rank order changes, but the place to verify it and the cadence on which it updates do not.

Calculator: Estimate a Producer’s Market Share

Use your own tonnage figures — this year’s Table 10, a company earnings report, or a hypothetical scenario — to see what share of total U.S. production a given output level represents, and how it would stack up against the 2023 top 8.

Assumptions: the default total (579.4 million short tons) is derived from Peabody's confirmed 104.3-million-ton output divided by its confirmed 18.0% share in 2023 — replace both fields with current-year EIA figures for an up-to-date comparison. This calculator does not account for coal type (thermal vs. metallurgical), export volume, or heat content; it measures raw tonnage share only.

Why This List Matters Beyond the Energy Sector

Coal production rankings aren't just an energy-sector curiosity — the scale and location of these operations shape logistics and land use well outside utility markets.

Rail and Infrastructure

• The rail corridors built to move Powder River Basin and Illinois Basin coal — the two regions where Peabody, Arch, and Alliance Resource Partners concentrate output — are shared infrastructure that also carries grain, fertilizer, and farm equipment through the same rural corridors.
• Appalachian haul roads and sidings built for CONSOL Energy's longwall operations double as logistics routes for timber and wood products in forest-adjacent counties.

Metallurgical Coal and Steel Supply

• A portion of output from Arch Resources and other Appalachian and Powder River producers goes to metallurgical (coking) coal rather than thermal coal, feeding domestic steelmaking used in bridges, pipelines, and heavy infrastructure.
• Steel demand tied to public infrastructure spending is one reason metallurgical-coal-focused producers can diverge from the broader thermal coal market even when utility demand softens.

Land Stewardship on Tribal Lands

• Navajo Transitional Energy Co's position at 7.9% of national output is unusual among the top producers because its structure ties mining revenue and reclamation decisions directly to the Navajo Nation, rather than to external shareholders — a distinct governance model worth understanding if you're evaluating land-use or reclamation commitments in the Four Corners region.

Satellite Intelligence for Coal and Mineral Exploration

Ranking tables like EIA's Table 10 describe what has already been mined. A separate question — where the next economically viable coal or mineral deposit sits — is where satellite-based exploration tools come in. Farmonaut's satellite-based mineral detection platform applies multispectral and hyperspectral remote sensing plus AI analysis to flag prospective zones in both greenfield and established mining regions, without ground disturbance during the early screening phase.

• Coverage: Farmonaut's exploration technology operates across more than 18 countries and a range of geological terrains.
• Speed: Satellite-based screening can compress early-stage exploration timelines relative to ground survey methods, since large areas are assessed remotely before any field crew is deployed.
• Non-invasive: Early-stage satellite analysis requires no ground disturbance, which aligns with reclamation and environmental-review requirements on land adjacent to active coal operations.

Farmonaut's Premium and Premium+ mineral intelligence reports include satellite-based prospectivity maps, geological interpretation, and 3D subsurface modeling. For a technical walkthrough of the mapping methodology, see the 3D GIS integration toolkit.

Pro tip: If you're screening a coal or mineral prospect and want a satellite-first starting point rather than commissioning a ground survey blind, map your mining site here.

Frequently Asked Questions

Q1: According to the EIA's 2023 Annual Coal Report, Table 10, which companies were the major U.S. coal producers?

Ranked by 2023 short tons produced: Peabody Energy Corp (104.3 million, 18.0% share), Arch Resources Inc (75.3 million, 13.0%), Navajo Transitional Energy Co (45.7 million, 7.9%), Alliance Resource Partners LP (34.877 million), ACNR Holdings Inc (32.178 million), CONSOL Energy Inc (26.377 million), and NACCO Industries Inc (23.640 million). These seven are confirmed from EIA's Table 10; the 8th-ranked company should be verified directly from the source PDF, since exact tonnage below the top 7 wasn't reliably available in the material reviewed for this article.

Q2: What was Peabody's exact share of U.S. coal production in 2023?

18.0%, on 104.3 million short tons, per EIA's Annual Coal Report Table 10 — the largest individual share among all 21 named major producers that year.

Q3: How much of total U.S. coal output did the top 8 producers supply in 2023?

64.7% combined. Expanding to the full top 21 major producers named in Table 10 brings combined share to 85.4%, leaving roughly 14.6% spread across smaller, unnamed operators.

Q4: Does EIA update this list every year, and when?

Yes. EIA republishes Table 10 annually as part of its Annual Coal Report, with the full report — covering the prior calendar year — typically released in October or November. Between annual releases, EIA's quarterly coal production data gives a less granular but more current directional read. The current version of Table 10 always lives at eia.gov/coal.

Q5: Is "major U.S. coal producers" the same as "largest coal companies by revenue"?

No. Table 10 ranks by tonnage mined, not revenue, reserves, or market capitalization. A company mining more thermal coal can outrank a company with a smaller tonnage of higher-value metallurgical coal, even if the metallurgical producer's revenue per ton is higher.

Q6: How is Farmonaut's technology used in coal and mineral exploration?

Farmonaut's satellite-based mineral detection platform applies multispectral and hyperspectral remote sensing with AI analysis to identify prospective zones without ground disturbance during early-stage screening, supporting both new exploration targeting and reclamation planning on existing mining land.

Q7: Where can I verify these production figures myself instead of relying on a third-party summary?

Go directly to EIA's Table 10 PDF. Third-party aggregators like Statista's leading U.S. coal producers dataset repackage the same EIA figures, but the PDF is the primary source and the one to cite if precision matters.

Conclusion

EIA's Table 10 gives a precise, checkable answer to "who are the major U.S. coal producers": Peabody Energy Corp, Arch Resources Inc, and Navajo Transitional Energy Co lead by a wide margin, together with Alliance Resource Partners, ACNR Holdings, CONSOL Energy, and NACCO Industries filling out the confirmed top 7 for 2023, all combining with the remaining top-8 and top-21 tiers to cover 64.7% and 85.4% of national output respectively. Those numbers will shift as EIA releases each subsequent Annual Coal Report — use the four-step verification method above, anchored on eia.gov/coal, to pull whatever year's list you actually need.
