Setting up a Bitcoin mining farm: infrastructure guide 2026
Professional Bitcoin mining requires a strategic approach and robust infrastructure to remain competitive in 2026. With network difficulty constantly rising and margins shrinking, setting up an efficient mining farm is becoming a major technical and economic challenge. This guide details all the essential aspects of creating a profitable and sustainable professional mining operation.
Electrical infrastructure: the foundation of your mining farm
Calculating power requirements
The first step is to assess your power requirements. A modern ASIC such as the Antminer S21 consumes 3,520W, or approximately 84 kWh per day. For a farm of 100 machines, you need to allow for:
- Total power : 352 kW minimum
- Safety margin : +15%, i.e. 405 kW
- Monthly consumption : ~252,000 kWh
The cost of electricity remains the key factor. In 2026, aim for a tariff of less than €0.08/kWh to remain profitable with Bitcoin at €59,000.
Professional electrical installation
Your infrastructure must comply with industry standards:
Transformer and distribution:
- MV/LV transformer suited to your power requirements
- Low-voltage main distribution board (LVDB) with residual current protection
- Distribution by sector to facilitate maintenance
Cabling and protection:
- Cables sized in accordance with standard NF C 15-100
- 30mA residual current circuit breakers per circuit
- Type 1+2 surge arrester at the head of the installation
- Accessible emergency shut-off system
Electrical redundancy with two independent power supplies can prevent significant losses in the event of mains power failures.
Cooling system suited to the French climate
Air cooling: a cost-effective solution
Cooling accounts for 15 to 20 per cent of total energy consumption. In France, air cooling remains the optimal solution for 8 out of 12 months:
Recommended configuration:
- 380V industrial fans with variable frequency drives
- Air circulation via hot/cold aisles
- Target temperature: 25–30°C at the air inlet
- Air flow rate: minimum 2,000 m³/h per ASIC
Seasonal optimisation:
- Winter: natural cooling (free cooling)
- Summer: support via misting or air conditioning
Advanced solutions for summer
For hot periods, there are several options available to you:
| Solution | Installation cost | Energy consumption | Efficiency |
|---|---|---|---|
| Industrial air conditioning | €50,000 | +25% | Excellent |
| Evaporative cooling | €25,000 | +10% | Good |
| Liquid cooling | €100,000 | +5% | Optimal |
Monitoring your Bitcoin mining operation allows you to automatically adjust the cooling system according to conditions.
Design and layout of the space
Calculation of required floor space
For an efficient farm, allow for:
- Mining space : 0.5 m² per ASIC (including circulation space)
- Technical area : 20 per cent of the mining space
- Office/monitoring : minimum 15 m²
- Spare parts storage : 10 m² for 100 machines
Example for 100 ASICs:
- Total space: 75 m²
- Ceiling height: minimum 3.5 m
- Delivery access: gate at least 3 m wide
Optimised layout
The layout of the space has a direct impact on efficiency:
Aisle-based layout:
- 1.2m aisles between the racks
- Shelf height: maximum 2 metres
- 4 ASICs per shelf to facilitate maintenance
- Physical separation of hot and cold air flows
Dedicated areas:
- Quarantine area for faulty machines
- Fully equipped repair workshop
- Technical room for electrical and network systems
Equipment selection and configuration
Selection of ASICs in 2026
The selection process should prioritise energy efficiency:
Recommended ASICs:
- Antminer S21 Pro : 15 J/TH, 234 TH/s
- Whatsminer M60S : 16 J/TH, 172 TH/s
- Avalon A1566 : 18 J/TH, 185 TH/s
With Bitcoin at €59,000 and a yield of 0.00000054 BTC/TH/day, an ASIC at 15 J/TH generates approximately €7.60/day in gross revenue.
Robust network infrastructure
Internet connectivity:
- Dedicated fibre-optic connection, minimum 100 Mbps
- Redundancy with a second provider
- Professional router with built-in firewall
- Managed switch with at least 48 ports
Pool configuration:
- Main pool + automatic backup
- Optimal configuration of mining pools to maximise revenue
- 24/7 monitoring of connections
Using a proxy for Bitcoin mining can improve stability and reduce rejections.
Thermal management and energy efficiency
Insulation and sealing
Good insulation reduces cooling costs:
Recommended materials:
- Thermal insulation with a minimum R-value of 6
- Continuous vapour barrier
- Insulated doors with an entrance vestibule
- High-performance double-glazed windows
Heat recovery
The heat produced can be utilised:
Possible applications:
- Heating of agricultural greenhouses
- Biomass drying
- District heating via heat exchangers
- Domestic hot water production
A farm comprising 100 ASIC units produces ~300 kW of thermal energy, equivalent to heating 15 homes.
Regulatory and administrative aspects
Required authorisations
Mandatory procedures:
- Planning permission if the area exceeds 20 m²
- ICPE operating declaration if output >1 MW
- Consuel certification for the electrical installation
- Connection agreement with Enedis/ELD
Environmental compliance
2026 regulations:
- Carbon declaration for installations >500 kW
- Compliance with noise limits (35 dB at night)
- E-waste management plan
- Impact assessment if capacity exceeds 2 MW
Authorisation processing times can be up to 12 months. Plan for these procedures from the design stage onwards.
Financial analysis and profitability
Initial investment
Typical budget for 100 ASICs:
| Item | Estimated cost |

| Building/fit-out | €180,000 |
| Cooling system | €60,000 |
| Ancillary equipment | €40,000 |
| Total | €1,200,000 |
Profitability calculation

Conclusion
Setting up a Bitcoin mining farm in 2026 requires a rigorous, professional approach. Electrical infrastructure, cooling and operational management are the cornerstones of profitability. With careful planning and an initial investment of around €12,000 per ASIC (all-inclusive), a well-designed farm can generate an attractive ROI despite intensifying competition.
The key to success lies in continuous optimisation and adapting to technological developments. To maximise your chances of success, create an account and benefit from professional management and monitoring tools tailored to modern mining farms.
