Campus profile Operating
Hamar / N01 campus
Green Mountain (TikTok anchor) · Hamar, Innlandet, Norway
The resource footprint
Modelled averageIn one day, this campus consumes about
3.6550-metre swimming pools
Filled with the volume of water consumed by the campus and its electricity supply.
The actual estimate2,411,547 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
- Cold-climate free cooling; waste heat to a neighbouring trout farm and district heat
- Basis
- Modelled from cooling design — WUE 0.05 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
- $0.29–0.84 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
- 13,222 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
- 30.7 kt/yr — climate, not air quality
The project, approvals and community concerns
- Who asked for it
- ByteDance / TikTok — a ten-year lease taken to satisfy EU data-residency commitments
- Who approved it
- Hamar municipality; Norwegian hydro supply; Statnett connection
- What it serves
- TikTok's European user data under Project Clover
- IT capacity
- 150 MW current capacity / 300 MW full-build scenario
Norwegian hydro makes this the lowest-carbon site in the dataset by a wide margin. It exists because of European data-protection law, not because compute is cheaper here.
