Not built yet. Every figure below is what it would take and emit at the capacity its owners have announced.
Water — consumed, not returned
Taken from the basin2,336M gal/yr
Evaporated on site123M gal
Making the power2,213M gal
Basin stressExtremely High
Where the water comes from
Closed loop — negligible draw
Cooling
Air-cooled closed loop — evaporative cooling is impractical at Gulf temperatures and water cost
Basis
Modelled from cooling design — WUE 0.05 L/kWh
Air — what the stacks emit
Nitrogen oxides1,117t/yr
Sulphur dioxide186t/yr
Fine particulates65.2t PM2.5
Health damages$56.4M/yr
Where it burns
UAE — Emirates Water & Electricity
Generation mix
Gas 63 · Nuclear 24 · Solar 12
CO₂e
3,016 kt/yr — climate, not air quality
Who wanted it
Who asked for it
OpenAI and the UAE government — partnership with Oracle, Nvidia, Cisco and SoftBank announced in 2025
Who approved it
UAE federal approval; US Commerce Department export licences for the advanced chips are the binding constraint, not local permits
What it serves
OpenAI models for the Gulf region plus UAE sovereign AI
IT capacity
0 MW running of 1,000 MW announced
Phase one of an announced 5 GW campus. Almost all UAE freshwater is desalinated, so water cooling is off the table; the tradeoff is higher electricity use on a gas-and-nuclear grid.
Water and air figures are modelled from disclosed capacity, not measured — site-level
error is roughly ±40%. Diesel backup generators are not counted, so on-site figures are floors.
