Bitcoin Mining Electricity Costs by State: The 2026 Guide
Electricity is not a line item in Bitcoin mining — it is the business. For most mining operations, power accounts for 40–70% of total operating costs. At scale, a $0.02/kWh difference between states translates to tens of thousands of dollars per year per megawatt of deployed hashrate.
This guide covers mining electricity rates across all 50 US states, explains why some states dominate industrial mining, and gives you the framework to model how your local rate affects profitability.
Why Electricity Cost Is the #1 Variable
Before diving into state data, it helps to understand the math. A single Antminer S21 XP draws 3,645 watts continuously. Running 24/7, that's roughly 2,623 kWh per month.
At different electricity rates, monthly power cost per machine:
| Rate ($/kWh) | Monthly Power Cost (S21 XP) | Annual Power Cost |
|---|---|---|
| $0.03 | $78.69 | $944 |
| $0.05 | $131.15 | $1,574 |
| $0.07 | $183.61 | $2,203 |
| $0.10 | $262.30 | $3,148 |
| $0.12 | $314.76 | $3,777 |
| $0.15 | $393.45 | $4,721 |
The spread between $0.03 and $0.15 is $3,777 per machine per year. At 100 machines, that's $377,700 — the difference between a profitable operation and a money-losing one.
How States Are Rated
The data below uses commercial/industrial electricity rates where available. Industrial rates (for large-scale consumers above 500 kW demand) are typically lower than residential rates by 30–60%. Large mining operations negotiate power purchase agreements (PPAs) that can go even lower — sometimes as low as $0.02–$0.03/kWh in optimal markets.
Rate tiers used:
- Tier 1 (Best): < $0.06/kWh industrial
- Tier 2 (Good): $0.06–$0.09/kWh industrial
- Tier 3 (Marginal): $0.09–$0.12/kWh industrial
- Tier 4 (Poor): > $0.12/kWh industrial
The Top 10 Cheapest States for Bitcoin Mining
1. Washington — $0.032–$0.045/kWh
Washington is the undisputed leader. Abundant hydroelectric power from the Columbia River basin keeps industrial rates among the lowest in the country. Eastern Washington (Chelan, Douglas, Grant counties) is home to some of the highest concentrations of Bitcoin mining per capita in the US.
The catch: available industrial capacity is increasingly constrained. PUDs (public utility districts) have imposed moratoria on new mining connections in some areas, and competition for low-cost power is fierce.
2. Louisiana — $0.042–$0.052/kWh
Louisiana benefits from cheap natural gas and a deregulated industrial power market. Large industrial customers can negotiate favorable rates. The state has actively courted data center and mining investment with favorable permitting.
3. Idaho — $0.044–$0.054/kWh
Like Washington, Idaho has significant hydro generation. Southern Idaho (around the Magic Valley) has seen mining activity driven by affordable rates and available industrial land. Idaho Power serves much of the south and has generally been accommodating to large load customers with proper demand management agreements.
4. Arkansas — $0.045–$0.058/kWh
Arkansas has consistently ranked among the cheapest states for industrial power, driven by a mix of natural gas and coal generation. The state passed legislation in 2023 explicitly protecting Bitcoin miners' right to operate — making it politically friendly as well as economically attractive.
5. Kentucky — $0.047–$0.058/kWh
Kentucky's legacy coal infrastructure, while declining, still supports low industrial rates. The state transitioned aggressively to host mining operations as coal facilities shut down — repurposing existing grid infrastructure and power transmission that would otherwise sit idle.
6. Wyoming — $0.048–$0.060/kWh
Wyoming combines cheap power with near-zero corporate taxes and the most crypto-friendly regulatory environment in the US. The state has passed more Bitcoin/crypto legislation than any other. Industrial rates benefit from low-cost natural gas and coal. Land is cheap, climate is cold (reducing cooling costs), and regulation is minimal.
7. Montana — $0.050–$0.062/kWh
Montana has significant hydro capacity (particularly in the west) and low population density. The state's industrial power market is less developed than Washington or Idaho, but rates remain competitive. Cold winters reduce cooling load substantially.
8. Nebraska — $0.050–$0.063/kWh
Nebraska is one of the few states where the entire power grid is publicly owned — no private utilities. Public power districts tend to have stable, lower rates. The state's central location provides grid redundancy and the flat terrain supports wind energy that increasingly backs industrial loads.
9. North Dakota — $0.051–$0.063/kWh
North Dakota has significant wind resources and cheap stranded natural gas from oil production (associated gas that would otherwise be flared). Some mining operations have co-located directly with oil wells to capture this otherwise-wasted energy.
10. Texas — $0.035–$0.065/kWh (variable)
Texas deserves special mention because it's the most complex market. The ERCOT grid is deregulated, and power prices fluctuate dramatically. Sophisticated miners use demand response programs — essentially agreeing to curtail during grid stress events in exchange for significantly discounted rates.
The best Texas miners pay $0.02–$0.04/kWh on average by participating in ancillary services markets. The worst pay $0.10+ if they're on unfavorable contracts or don't curtail during price spikes. Texas is a high-skill power market, not a passive one.

Why the Top 5 States Dominate Mining
Three structural advantages explain why Washington, Louisiana, Idaho, Arkansas, and Wyoming attract the majority of US mining capacity:
1. Generation mix. States with hydro, natural gas, or coal generation have lower fuel input costs than those relying on imported power or premium renewables. Hydro in particular has near-zero marginal fuel cost once infrastructure is built.
2. Infrastructure overhang. States with legacy industrial economies (mining, manufacturing, coal) often have stranded grid capacity — transmission lines, substations, and power generation facilities that were built for industry that no longer exists. Bitcoin mining absorbs this capacity cheaply.
3. Regulatory posture. States like Wyoming and Arkansas have explicitly welcomed miners. No environmental challenges to permitting, no regulatory hostility to high-density power loads, and in some cases active tax incentives. Compare to California, where utility rate structures, carbon accounting, and grid management policies all work against energy-intensive industries.
Industrial vs. Residential Rates: The Gap Matters
One critical nuance: the table above shows industrial rates. If you're mining from home or a small facility, you're paying residential rates, which are typically $0.10–$0.20/kWh across most of the US.
Even in Washington, residential rates average $0.10/kWh — three times the industrial rate. The economics of home mining look entirely different from large-scale industrial operations.
For home miners, the relevant question is whether your residential rate is below your mining shutdown threshold — the rate at which daily power costs exceed daily revenue. At current network difficulty and BTC price, that threshold for the S21 XP is roughly $0.11–$0.13/kWh.
The Hidden Costs: Beyond the Electricity Rate
Electricity rate is primary, but not the only power-related cost:
- Demand charges: Many industrial utilities charge per peak kW of demand, not just per kWh consumed. A 1 MW facility with a flat load profile can face $10,000–$30,000/month in demand charges on top of the per-kWh rate.
- Power factor penalties: Mining equipment with poor power factors can trigger utility penalties; quality PDUs and power management help.
- Interconnection costs: Tapping into higher-voltage transmission requires utility-side infrastructure upgrades. In constrained markets, queues are years long and costs can be millions of dollars.
- Cooling: In hot climates (Arizona, Florida, Texas summers), cooling adds 10–20% to effective power consumption. States with cold climates (Wyoming, Montana, Minnesota) offset higher rates with near-zero cooling loads for much of the year.

How to Use This Data
The rate table gives you a starting point. To calculate actual profitability:
- Identify your rate: Industrial if you have a large facility, residential if home-mining
- Factor in demand charges if applicable (ask your utility)
- Add cooling overhead (10–20% in hot climates, near zero in cold climates)
- Model at multiple BTC prices and difficulty levels — conditions change
The MineCast calculator lets you enter your exact electricity rate and model profitability across multiple hardware options, risk scenarios, and time horizons. It factors in halving schedules, difficulty growth, and BTC price appreciation assumptions.
If you're in a Tier 3 or Tier 4 state, it doesn't necessarily mean mining is impossible — it means your hardware efficiency needs to be exceptional, your BTC price assumptions need to be more aggressive, or you need to find a way to access lower-cost power.
The cheapest state in the country with the wrong hardware can still lose money. The right hardware in an average state can still be profitable. Electricity rate is the biggest lever, but it's not the only one.
