Campus profile Operating
Beauharnois
Bitfarms / Hydro-Québec industrial park · Beauharnois, Québec, Canada
The resource footprint
Modelled averageIn one day, this campus consumes about
3.650-metre swimming pools
Filled with the volume of water consumed by the campus and its electricity supply.
The actual estimate2,379,831 US gallons consumed
Power-plant water may come from a different watershed. This is a volume comparison, not a claim that households lose this water.
At current operating capacity · Annual model spread evenly over time, not a live meter. Site estimates may differ by roughly ±40%.
Comparison sizes & sources
One pool = 50 × 25 × 2 metres = 2.5 million litres (about 660,430 US gallons). Pool depths vary; this is a defined comparison size.
One home-year = 10,791 kWh, the EIA’s 2022 average US residential electricity purchases. This excludes electricity generated at home and is a fixed US benchmark for all sites.
One car-year = 4.6 tonnes CO₂, the EPA’s typical passenger vehicle tailpipe estimate. The campus model is in CO₂e; the comparison expresses approximate climate scale, not equal mixtures of pollutants.
Monthly values are annual totals ÷ 12; daily values are annual totals ÷ 365. Actual demand varies. Comparisons cover the whole campus, including non-AI uses.
Water: see the numbers and sources
This is water used up, mainly through evaporation. Power-generation water may be used in a different watershed.
- Pressure on local water
- Low — a regional measure of demand compared with available water
- Where the water comes from
- Closed loop — negligible draw
- Cooling
- Free cooling most of the year on hydro power
- Basis
- Modelled from cooling design — WUE 0.10 L/kWh
Air: see the numbers and sources
The totals include nitrogen oxides, sulphur dioxide and fine particles. They cover both this site and the power plants supplying it.
- Health range
- $0.28–0.81 million a year. Lower bound is EASIUR national mid-range; upper is EPA benefit-per-ton at a ~$12M VSL.
- Statistical deaths
- 0.07 a year at that VSL — a national-average conversion from tons, not a local concentration study.
- Equals
- 12,844 cars of NOx
- Where it burns
- Norway — Statnett
- Generation mix
- Hydro 88 · Wind 10
- Diesel backup
- Diesel backup is not yet counted for this campus, so on-site air figures are a floor.
- CO₂e
- 29.8 kt/yr — climate, not air quality
The project, approvals and community concerns
- Who asked for it
- Mixed hosting customers; several Québec sites have been re-leased from bitcoin miners to AI operators
- Who approved it
- Hydro-Québec paused new large-load connections in 2023 and now allocates blocks selectively, explicitly deprioritising crypto in favour of AI and industry
- What it serves
- Compute hosting converting from crypto mining to AI training
- IT capacity
- 120 MW current capacity / 250 MW full-build scenario
Québec is the clearest case of a utility rationing cheap clean power between competing digital uses. The crypto-to-AI conversion happening here is repeating across Texas and the Nordics.
