Powder River Basin — The World's Largest Coal Mine Complex
The Powder River Basin (PRB) in northeast Wyoming and southeast Montana is the most productive coal mining region in North America. PRB coal is sub-bituminous — lower heat content than Appalachian coal but much lower sulfur, making it preferred for US power plants with SO₂ restrictions (Clean Air Act).
| Mine | Operator | Output (Mt/yr) | Rank |
|---|---|---|---|
| North Antelope Rochelle | Peabody Energy | ~80 Mt | #1 US mine |
| Cordero Rojo | Foresight Energy | ~35 Mt | #2 US mine |
| Black Thunder | Arch Resources | ~50 Mt | #3 US mine |
| Belle Ayr | Foresight Energy | ~22 Mt | Major PRB |
Decline trajectory: Wyoming coal production peaked at 466 Mt in 2008. By 2023 it had fallen to ~250 Mt — a 46% decline driven by cheap natural gas, falling renewable costs, and utility coal plant retirements. Federal royalty revenues from PRB coal fell from $800M/yr to ~$400M/yr.
Wind Capacity Factor by Region (%)
Planned Wind Pipeline (GW)
Why Wyoming Wind Is World-Class
Wyoming sits at the convergence of the Rocky Mountain Front Range and the Great Plains — creating persistent, powerful winds driven by both mountain downslope flows and the continental pressure gradient. Capacity factors of 50–60% are common in southern Wyoming (vs. US average of ~35%).
| Zone | Avg Capacity Factor | Notes |
|---|---|---|
| Cheyenne / SE Wyoming | 55–62% | Best wind resource in US; consistent 30–40 mph sustained |
| Casper / Central WY | 42–50% | Large land area; Dunlap/Rolling Hills projects |
| Rawlins Corridor | 48–56% | TransWest Express transmission route |
| Big Horn Basin | 35–45% | Some transmission constraints |
TransWest Express: A 732-mile, 3 GW HVDC transmission line from Wyoming to Southern Nevada (Las Vegas). When complete (~2026), it will allow Wyoming wind to reach California and Nevada markets — potentially transforming Wyoming into a "green Saudi Arabia" for wind electricity.
Carbon Capture — Wyoming's Bridge Strategy
Wyoming has invested heavily in carbon capture, utilization, and storage (CCUS) as a strategy to preserve coal plant economics while reducing emissions. The state hosts several DOE-funded pilot projects.
| Project | Technology | Scale | Status |
|---|---|---|---|
| Dry Fork Station (Basin Electric) | Post-combustion CO₂ capture | 110,000 t CO₂/yr pilot | Pilot complete; full-scale TBD |
| Wyoming CarbonSAFE | Saline aquifer storage | 50+ Mt CO₂ storage capacity mapped | Site characterization ongoing |
| Integrated Test Center (Gillette) | Multiple CO₂ utilization techs | Competition facility | Operational since 2018 |
| Turquoise Hydrogen (HyVelocity) | Methane pyrolysis (turquoise H2) | 10,000 t H2/yr proposed | Pre-FEED 2024 |
Challenge: Cost of CCS at coal plants ($60–120/t CO₂) exceeds the avoided carbon cost in most scenarios. No commercial-scale coal CCS plant operates in the US today. The technology remains critical for industrial decarbonisation (cement, steel) rather than coal power.

Coal Mining Employment Trend
Just Transition — Wyoming's Fiscal Exposure
Wyoming has no state income tax; its government is funded almost entirely by mineral extraction royalties, severance taxes, and federal mineral leasing payments. The coal decline creates a structural fiscal crisis that no amount of wind development can immediately replace — wind royalties are smaller and less predictable.
| Revenue Source | 2008 Peak | 2023 Actual | Change |
|---|---|---|---|
| Coal severance tax | $485M/yr | ~$200M/yr | -59% |
| Federal mineral royalties | $780M/yr | ~$390M/yr | -50% |
| Oil & gas severance | $350M/yr | ~$450M/yr | +29% |
| Wind royalties (public land) | Negligible | ~$15M/yr | Growing |
Economic Snapshot
| Metric | Value | Notes |
|---|---|---|
| GDP | ~$44B | Smallest US state economy; 50th in total GDP |
| Per-capita GDP | ~$75,000 | 13th highest in US — driven by mineral wealth |
| Coal mining jobs | ~5,800 | Down from 8,200 in 2012; avg wage $95K/yr |
| Wind energy jobs | ~2,000 | Rapidly growing; avg wage ~$60K/yr |
| Electricity cost | ~10 c/kWh | Lowest in Mountain West; cheap coal + exports |
| Wind energy exported | ~60% | WY generates far more than state can consume |
Opportunity: Green Hydrogen + Data Centers
Wyoming's combination of world-class wind, vast land, cheap electricity, and low population is attracting green hydrogen and data center investment. Microsoft and Google have evaluated Wyoming wind for data center power purchase agreements. The state's legislature created the Wyoming Energy Authority in 2020 to actively court clean energy investment.
