Mining Farm Essentials

A clear, structured guide to understanding the core elements of a mining operation.

Power Determines Costs

The capacity you install sets transformer sizing, cabling layout, and power distribution. Reliable grid supply is crucial to keep your miners running smoothly and ensure long-term stability.

Cooling Shapes Efficiency and Hardware Life

Your choice of cooling affects PUE, noise levels, maintenance effort, and miner longevity. Proper thermal management also protects against overclocking risks.

Operations Drive Uptime

Efficient maintenance, spare parts availability, and regular inspections determine recovery speed from issues and influence your long-term returns.

📘Quick Reference

  • MW: Megawatt, 1 MW = 1000 kW, reflects site capacity.

  • kWh: Energy measurement for electricity use and billing.

  • TH/s: Measures miner computing power.

  • PUE: Ratio of total energy to IT energy. Lower numbers mean higher efficiency.

Site Selection Tips

  • Stable grid & low tariffs: prioritize a reliable electricity source.

  • Ample gas supply: improves operational independence.

  • High renewable share: storage + EMS smooths output.

  • Sensitive to heat, dust, or noise: hydro or immersion cooling keeps things calm.

  • Tight budget or open-air setups: air cooling is cheaper but noisier.

Energy Sourcing: Make the Right Choice

Your energy setup shapes your mining stability. The source you choose determines if your system requires transformers, standby generators, or storage solutions to maintain steady, reliable operation.

⚡ Grid Supply (Grid)

Flow: high-voltage input -> transformer -> distribution

Transformer Selection Guide

A critical step in the power chain: converting high-voltage 10/35kV transmission lines into miner-ready 415V/380V supply.

SCB14 Dry-type Transformer

Recommended: container-integrated

Safe, compact, and designed to keep your mining operation running smoothly while reducing energy loss.

S13 Oil-immersed Transformer

Recommended: outdoor standalone

Durable, weather-resistant, and highly efficient at heat dissipation—your budget-friendly solution for outdoor substations.

🔥 Gas Generation (Gas Genset)

Flow: gas source -> pretreatment -> gas genset -> distribution

Designed for Associated Gas

The upstream scrubber is crucial—removing H₂S and moisture to protect your engines. Depending on output voltage and distribution, a secondary transformer might not be needed.

Solar/Wind (Solar & Wind)

Flow: solar/turbine -> inverter -> battery -> distribution -> miners

Why BESS Is Essential

Renewable energy is intermittent. Without storage, voltage fluctuations can harm hashboards.

🔋System Building Blocks

  • PCS Converters: Bi-directional AC/DC conversion for flexible power flow.

  • BESS Battery Clusters: Store energy like reservoirs for steady, reliable output.

  • EMS System: Intelligent management for seamless switching between solar, wind, and grid power.

Cooling Decisions: Principles in Action

We move beyond theory to demonstrate real-world physics. From air convection to dual-loop liquid cooling, each solution follows its own logic.

Core KPI

Understand PUE first, then compare cooling options.

? What is PUE (Power Usage Effectiveness)?

PUE = Total Energy / IT Energy

The closer to 1.0, the better—less overhead from cooling and auxiliaries.

Ops Pitfalls: Know the Basics

These fundamentals are often overlooked, yet critical. Understanding them helps you evaluate system stability and compliance.

🔌Electrical Basics

Use XLPE insulated flame-retardant cables to avoid fire risks from ordinary PVC.

Regular Thermal Inspections

Scan terminals to find hotspots early and avoid failures from poor contacts.

💧Water Quality

🛡

Inner Loop

Contacts miners; strict requirements. Must use deionized water (conductivity < 5μS/cm).

Outer Loop

Connected to cooling tower; more lenient. Treated water is ok but add antifreeze and biocide/algaecide.

🌐Network Basics

Dual-WAN Redundancy

Primary fiber + backup Starlink/4G to reduce hashrate downtime.

🛡

VLAN Isolation

Physically separate production and management networks to prevent full-site spread.

📦Spare Parts Inventory

Repairs often take 20-30 days. To protect uptime, stock:

2%   Spare PSUs

5%   Spare Fans

1%   Control Boards

🖥Management Tools

Basic Management

Use vendor tools (e.g., BTC Tools) for batch pool configs and firmware updates.

Advanced Management

Recommend Foreman or Awesome Miner for automation, heatmaps, and yield analytics.

🌡Environment Control

💧

Dew Point Monitoring

Evaporative cooling raises humidity. Monitor dew point to avoid condensation short circuits at night.

Clean the Water Curtain

Curtains trap dust but clog with sludge. High-pressure cleaning is required to prevent overheating.
