Calculations

You can adjust six key levers of the plan: the compute target for 2029, the purchase cost per gigawatt, the price of transitional leasing, annual operations per gigawatt, the starting payroll and the annual growth of non-compute costs.

Default settings = the note's central scenario (12 GW in 2029; Epoch AI orders of magnitude converted to euros: €33.1bn per GW purchased, €7.4bn per GW leased per year).

Compute ambition (2029)

Available IT load targeted for 2029. The 2027-2029 trajectory scales in proportion.

Purchase cost per GW

Upfront CapEx to build and equip 1 GW of owned capacity (Epoch AI reference: ~€33bn).

Leasing price

Transitional leased capacity, per GW per year, to bridge the gap at the start.

Operations per GW·yr

Annual OpEx of owned capacity, per GW (Epoch AI reference: ~€0.8bn).

Payroll 2027

Compensation of the lean team (~1,760 people) in the first year.

Growth of non-compute costs

Annual growth of payroll and other expenses.
