Quick Answer
Assess Bitcoin mining infrastructure by evaluating seven factors: power capacity (megawatts available), energy costs ($/kWh), facility specifications (cooling, space, redundancy), hardware deployment (hash rate per MW), operational efficiency (uptime, maintenance), economic viability (ROI timeline), and strategic positioning (grid integration, energy independence). World-class operations achieve >98% uptime at <$0.04/kWh with efficient cooling and grid services.
Infrastructure Assessment Framework
1. Power Capacity Analysis
Primary Metric: Megawatts (MW) of electrical capacity
Formula:
Available Mining Capacity (MW) = Total Electrical Capacity - Critical Loads - Safety Margin
Evaluation Tiers:
| Capacity | Scale | Typical Operation |
|---|---|---|
| <1 MW | Hobby/Small | Home/garage mining (50-300 miners) |
| 1-5 MW | Small Commercial | Regional mining operation (300-1,500 miners) |
| 5-50 MW | Medium Commercial | Industrial facility (1,500-15,000 miners) |
| 50-200 MW | Large Enterprise | Major mining campus (15,000-60,000 miners) |
| >200 MW | Hyperscale | National-level operation (60,000+ miners) |
Example Calculation (50 MW facility):
Total Electrical Capacity: 55 MW (substation rating)
Critical Loads: 2 MW (offices, cooling controls, lighting)
Safety Margin: 3 MW (15% reserve)
Available for Mining: 50 MW
Hash Rate Potential:
Miners per MW: ~285 Antminer S21 (200 TH/s each, 3.5 kW)
Total Miners: 50 MW × 285 = 14,250 miners
Total Hash Rate: 14,250 × 200 TH/s = 2.85 EH/s (~0.6% of global hash rate)
Key Questions:
- Is power supply dedicated or shared with other industries?
- Can capacity scale (expandable substation)?
- Redundant power sources (backup generators, dual feeds)?
See: Mining Infrastructure and National Power
2. Energy Cost Evaluation
Critical Metric: Cost per kilowatt-hour ($/kWh)
Profitability Thresholds:
| Energy Cost | Profitability | Recommendation |
|---|---|---|
| <$0.03/kWh | Highly Profitable ✅ | Excellent location, scale aggressively |
| $0.03-0.05/kWh | Profitable ✅ | Good location, proceed confidently |
| $0.05-0.07/kWh | Marginal ⚠️ | Monitor Bitcoin price, efficiency critical |
| $0.07-0.10/kWh | Breakeven Risk ⚠️ | Only with exceptional hardware efficiency |
| >$0.10/kWh | Unprofitable ❌ | Avoid unless strategic reasons |
Energy Source Assessment:
Renewable Energy (preferred):
- Hydroelectric: ~$0.02-0.04/kWh (best cost + sustainability)
- Wind: ~$0.03-0.06/kWh (intermittent but cheap)
- Solar: ~$0.04-0.07/kWh (daytime only, battery costs increase)
- Geothermal: ~$0.03-0.05/kWh (stable, renewable)
Fossil Fuels:
- Natural Gas: ~$0.03-0.06/kWh (abundant, flexible)
- Coal: ~$0.04-0.07/kWh (cheap but regulatory risk)
- Flare Gas Capture: ~$0.01-0.02/kWh (stranded energy monetization)
Nuclear:
- Grid Nuclear: ~$0.05-0.08/kWh (stable, zero carbon)
- SMR (Small Modular Reactors): Future potential (~$0.04-0.06/kWh)
Questions:
- Is pricing fixed or variable (spot market risk)?
- Long-term contracts available (price stability)?
- Demand response programs (paid to shut off during peak demand)?
- Stranded energy opportunities (curtailed renewables, flare gas)?

3. Facility Specifications
Space Requirements:
Mining Density:
Space per Miner: ~1-2 square feet (rack-mounted)
Aisle Space: 4-6 feet (maintenance access)
Total Space Factor: ~3-4 sq ft per miner (including aisles, staging)
Example (10,000 miners):
Gross Floor Area: 10,000 × 3.5 sq ft = 35,000 sq ft (~0.8 acres)
Plus: Electrical rooms, offices, storage = 45,000 sq ft total (~1 acre)
Ceiling Height:
- Minimum: 12 feet (basic airflow)
- Recommended: 16-20 feet (optimal cooling, equipment access)
Cooling Infrastructure:
Cooling Methods:
| Method | Cost | Efficiency | Climate Suitability |
|---|---|---|---|
| Air Cooling (direct) | Low | Moderate | Cool climates only |
| Evaporative Cooling | Low | High | Dry climates ✅ |
| Immersion Cooling | High | Excellent | Any climate ✅ |
| Hybrid (Air + Evap) | Moderate | High | Most climates ✅ |
Power Usage Effectiveness (PUE):
PUE = Total Facility Power / IT Equipment Power
Benchmarks:
- Excellent: 1.05-1.10 (immersion cooling)
- Good: 1.10-1.20 (evaporative + air)
- Average: 1.20-1.40 (air cooling only)
- Poor: >1.40 (inefficient design)
Example:
Miners: 50 MW
Cooling: 5 MW (evaporative + fans)
Lights/Offices: 0.5 MW
Total: 55.5 MW
PUE: 55.5 / 50 = 1.11 (excellent ✅)
Electrical Infrastructure:
- Voltage: 480V three-phase (industrial standard)
- Distribution: PDUs (Power Distribution Units) rated 200-400 kW each
- Redundancy: N+1 design (spare capacity for failures)
- Monitoring: Real-time power quality, SCADA systems
Internet Connectivity:
- Bandwidth: 10-100 Mbps (minimal data, low latency priority)
- Redundancy: Dual ISPs, cellular backup (99.99% uptime target)
- Latency: <100ms to mining pool servers
4. Hardware Deployment
Miner Selection Criteria:
Efficiency (Joules per Terahash):
| Generation | Efficiency | Competitiveness | Lifespan |
|---|---|---|---|
| Latest (2024-2025) | 15-18 J/TH | Excellent ✅ | 3-4 years |
| Current (2021-2023) | 18-30 J/TH | Good ✅ | 2-3 years |
| Outdated (2018-2020) | 30-50 J/TH | Marginal ⚠️ | <2 years |
| Obsolete (<2018) | >50 J/TH | Unprofitable ❌ | 0 years |
Deployment Density:
Miners per MW: 1,000,000 watts ÷ Miner Wattage
Example (Antminer S21, 3,500W): 1,000,000 ÷ 3,500 = 285 miners per MW
Hash Rate per MW:
Hash Rate per MW = Miners per MW × Hash Rate per Miner
Example: 285 × 200 TH/s = 57,000 TH/s = 57 PH/s per MW
Investment Calculation:
Hardware Cost per MW: Miners per MW × Miner Price
Example: 285 × $3,500 = ~$1 million per MW (hardware only)
Questions:
- Mix of miner models (hedge against obsolescence)?
- Purchasing vs. hosting (capital vs. operational model)?
- Replacement schedule (maintain efficiency as models improve)?

6. Economic Viability
Return on Investment (ROI) Calculation:
Total Capital Investment:
- Hardware: $50M (50 MW × $1M/MW)
- Facility Build-Out: $20M (electrical, cooling, building)
- Land/Permitting: $5M
Total: $75M
Annual Revenue (at $50k BTC, 500 EH/s global hash rate):
- Hash Rate: 2.85 EH/s (50 MW facility)
- Network Share: 2.85 / 500 = 0.57%
- Daily BTC: 900 × 0.0057 = 5.13 BTC
- Annual BTC: 5.13 × 365 = 1,872 BTC
- Revenue: 1,872 × $50,000 = $93.6M
Annual Costs:
- Electricity: 50 MW × 24 hrs × 365 days × $0.04/kWh = $17.5M
- Operations: $10M (staff, maintenance, overhead)
Total: $27.5M
Annual Profit: $93.6M - $27.5M = $66.1M
ROI: $75M ÷ $66.1M = 1.13 years (13.6 months) ✅
Sensitivity Analysis:
| Variable | Change | New ROI | Impact |
|---|---|---|---|
| Baseline | - | 13.6 months | - |
| BTC Price | $30k (-40%) | 34 months | High risk ⚠️ |
| BTC Price | $75k (+50%) | 8 months | Excellent ✅ |
| Electricity | $0.06/kWh (+50%) | 18 months | Moderate ⚠️ |
| Global Hash Rate | 750 EH/s (+50%) | 20 months | Significant ⚠️ |
Break-Even Analysis:
Break-Even BTC Price = Annual Costs ÷ Annual BTC Mined
Example: $27.5M ÷ 1,872 BTC = $14,690/BTC
Interpretation: Profitable above ~$15k BTC (current: $50k = 3.4x margin ✅)
See: How to Analyze Bitcoin Mining Economics
7. Strategic Positioning
Grid Integration Value:
Demand Response Programs:
- Texas ERCOT: Paid $50-150/MWh to shut off during peak demand
- Example: 50 MW facility, 100 hours/year curtailment = $250k-750k additional revenue
- Benefit: Grid stabilization services improve profitability
Renewable Energy Integration:
- Absorb excess solar/wind (prevent curtailment)
- Finance renewable infrastructure (guaranteed offtaker)
- Example: Flare gas capture converts waste into revenue while reducing emissions
National Security Considerations:
- Domestic hash rate contribution (cyber-sovereignty)
- Energy independence (monetize domestic resources)
- Economic development (jobs, tax revenue)
