A tenant has asked for liquid-cooled racks. Which of your halls can honestly say yes?
Your situation
Colocation vacancy in the large European markets is low, so the question from a prospective AI tenant is rarely whether you have space. It is whether the space can be fed and cooled at the density they plan, and by when.
Operators carry many halls of different vintages. A hall-by-hall answer built on each site's own assumptions makes the portfolio impossible to compare, and the hall that looks best on total kilowatts is not always the one that can host the racks soonest.
A commitment made to a tenant is a commercial one. A figure that is wrong in either direction costs something: overpromise and you carry the penalty, underpromise and the tenant signs elsewhere.
The decision this informs
Which halls to offer a given AI tenant, at what density, and which relief to start ordering first.
THE FIRST QUESTIONOf my halls, which can host this tenant's density soonest, and what sets the date?
What you probably already have
- Per-hall contracted and committed capacity from your own capacity management records
- As-built electrical single-lines and busway layouts for each hall
- Existing tenant loads and the density each tenant is already contractually allowed
The constraints most likely to decide your answer
- Available rack positions
Free positions on paper are not the same as positions that can be fed at the tenant's density.
The cheapest constraint to discover and the most awkward to relieve, because it is somebody's tenancy.
- UPS capacity (protected load)
Shared protected capacity across tenants is where one tenant's increase becomes another's limit.
AI training loads step harder than anything a 2014 UPS was specified for.
- CDU capacity at site conditions
Liquid cooling shifts the question from the room to the distribution unit and the site's own conditions.
A CDU rated at a 5 K approach, on a site whose facility water leaves it 2 K, is not the CDU you bought.
The route through what can be bought
It starts free and each step credits or informs the next; none is required. Prices are read from the live catalogue.
- Free capacity checkFree, no card
Run it on the hall a tenant is asking about to see the likely binding constraint before a commercial conversation.
- Density Screen€4,500
5 working days from a complete intake
One hall, with the inputs nobody has measured listed so they can be measured before the tenant signs.
- Portfolio Screen — deposit€15,000 deposit; opens a scoped engagement priced at €60,000 to €140,000
Several halls ranked under one methodology, so the offer goes to the hall that can deliver soonest.
- Hall Watch€6,000 every 3 months
Tenants and loads change; a hall re-solved each quarter keeps the answer current.
What to ask us before you rely on the answer
- Is the ranking of halls stable if the assumed inputs move within their stated ranges?
- Which hall's result rests on the weakest evidence, so we know where to measure first?
- How is shared UPS and cooling capacity treated across tenants in the result?
What it is not
- A ranking is not a commitment to any tenant and not a statement of what a tenant's contract permits.
- The result does not read your tenants' meter data unless you supply it, and it says so where it did not.
Time to Power sells no equipment, holds no inventory and owns no megawatts. A figure is modelled unless its evidence class says otherwise, and a date that rests on an assumed lead time is labelled as one.
