EverWind's October 16 announcement for Point Tupper, Nova Scotia, includes a useful cooling detail for AI infrastructure buyers: a sealed coolant circuit can coexist with water demand elsewhere in the cooling system.
The developer's release targets an initial 95 MW phase for late 2027, with further expansion subject to conditions.
EverWind plans a sealed water-glycol loop, with heat removed mainly through air and water-assisted cooling during the hottest weather. Under current design assumptions, it expects approximately 100,000 litres of daily water use for the initial phase and approximately 500,000 litres per day on average at full development.
These are design estimates for a planned facility. They are not operating measurements.
Operational analysis: identify the boundary of every cooling claim
For a buyer, the useful next step is to ask what exactly is closed. A facility diagram should distinguish the coolant circuit serving equipment from the equipment that ultimately rejects heat outdoors.
A sealed circuit says something about how fluid circulates within that boundary. A water budget answers a broader question: what water enters the site, where it goes and under which operating conditions it is needed. Procurement documents should connect those descriptions so that facilities staff, sustainability teams and customers are evaluating the same system.
I would ask for a schematic that names each circuit and heat exchanger, then link every water-use estimate to its measurement boundary. The supplier should identify whether an estimate covers cooling alone or other site uses, and whether it represents withdrawal, consumption or another defined quantity.
Without those definitions, apparently comparable proposals may be measuring different things.
An average day is only part of the operating envelope
The weather conditions that determine cooling demand deserve their own design review. Ask for the operating modes, the conditions that trigger a change between them and the assumptions about IT load during that change.
The review should include a hot-weather case, a water-supply restriction and the loss of a relevant cooling component. Those are proposed acceptance scenarios, not claims that Point Tupper has experienced these events.
For each scenario, establish the expected cooling capability, water requirement and permissible IT load. If a mode change affects available capacity, the operations team needs to know who authorizes it and how the workload scheduler receives that constraint.
An annual or daily average cannot supply those answers by itself. A useful water budget includes the conditions behind the estimate and the response when conditions move outside it.
Make maintenance part of the accounting
EverWind also says coolant removed during maintenance will be captured for recycling or appropriate off-site disposal. That commitment creates a practical handover question: what records will show that the intended process actually happened?
For a similar project, I would request procedures for draining, temporary storage, replenishment and waste transfer. Each procedure should identify the responsible party and the records retained. Fluid compatibility and handling instructions should travel with the equipment documentation.
The same principle applies to metering. Specify the measurement points, the reporting interval and the process for investigating a difference between expected and recorded use. A water report becomes more useful when an operator can trace a change back to weather, load, maintenance or a fault.
Tie expansion decisions to evidence
The announcement makes the expansion's grid connection conditional on required studies and approvals. That is a forward-looking commitment.
For operators evaluating this kind of phased campus, I would maintain a separate readiness record for each expansion. Cooling capability, water availability, electrical service and monitoring coverage should be assessed together before additional load is accepted.
The commercial capacity figure belongs alongside that record, with its definition and conditions attached. It should not replace the evidence that the next phase can operate within its electrical and thermal limits.
Point Tupper's published design is a useful starting point because it names both a sealed cooling loop and expected site water use. Buyers can use that distinction to request an operating envelope they can test, meter and manage as the facility develops.
