Rates per kWh, real monthly costs per machine, hidden fees to watch for: the complete guide to comparing Bitcoin hosting offers with full knowledge.
ASIC hosting is always priced in dollars per kilowatt-hour ($/kWh). That number drives your profitability far more than the purchase price of the machine: over a 5–7 year lifespan, electricity represents 70–85% of a miner's total cost of ownership.
In 2026, professional hosting rates typically range between $0.06 and $0.10/kWh depending on the country, the quality of the infrastructure and — this is the main trap — what is actually included in the advertised price.
Many providers advertise an attractive headline rate, then add billing lines: setup fees ($100–200 per machine), monthly maintenance fees, "management" surcharges, exit fees, or spot-indexed electricity that changes every month. A quoted $0.065/kWh quickly becomes a real $0.085–0.09/kWh.
The right question to ask any host: "What is the total cost per kWh, all included, with installation and basic maintenance, guaranteed by contract?" If the answer isn't a single number, be careful.
The math is simple: power (kW) × 720 hours × $/kWh rate. Here are the actual monthly costs at B Host Energy's $0.079/kWh all-inclusive rate:
| Machine | Power | Hashrate | Cost / month |
|---|---|---|---|
| Antminer S21+ Hydro | 5,925 W | 395 TH/s | ≈ $337 |
| Antminer S21 XP Hydro | 5,676 W | 473 TH/s | ≈ $323 |
| Antminer S23 Hydro | 5,510 W | 580 TH/s | ≈ $313 |
Note: the newer and more efficient the machine (lower J/TH), the more Bitcoin it produces per dollar of electricity. That's why the S23 Hydro costs less per month while delivering 47% more hashrate than the S21+.
A rate only matters if it's sustainable. Norway offers a rare combination: nearly 100% hydroelectric power, one of Europe's most reliable grids, a cold climate that optimizes cooling, and first-rate legal and geopolitical stability. The NO4 zone (northern Norway), where our machines run, has historically enjoyed the country's lowest prices.
This is what allows us to offer a single all-inclusive rate of $0.079/kWh: installation, electricity, hydro-cooling, basic maintenance, 24/7 site security, connectivity and a real-time dashboard. No extra lines on the invoice.
The electricity price difference alone pays for the hosting service — several times over.
At B Host Energy, the rate is contractually fixed for the commitment period. No surprise spot indexation.
Monthly, on actual metered kWh consumption, with a detailed statement. Payment in USD, EUR or BTC.
No. Installation is included, and there are no exit fees at the end of the contract.
