DarkNX Ontario AI campus

Project brief

What is publicly known

Status: planned. The evidence is a November 2025 Accelsius release saying DarkNX entered an agreement to use NeuCool across a proposed 300 megawatt campus in Ontario. It describes two 65 megawatt facilities in the first phase, with deployments scheduled for 2026 and 2027.

That is evidence of a supplier selection and a stated program, not evidence that construction or equipment delivery has begun. No operator, utility, regulator, or local planning source is included in the public record. What is known is the intended thermal chain.

Accelsius would capture chip heat with a dielectric fluid that boils inside a two-phase direct-to-chip loop. Johnson Controls chillers would serve the facility side. Accelsius says the design can accept warmer facility water, which could increase the hours when outdoor conditions help reject heat and reduce compressor work.

The actual result will depend on the Ontario site, server configuration, water temperatures, redundancy, and how much rack heat remains on air. Unknowns include the site address, land control, financing, permits, utility interconnection, construction contractor, compute vendor, rack density, equipment quantities, and the schedule beyond the first two buildings. The release also gives no signed contract value or delivery milestones.

These omissions prevent a view on cost or delivery confidence. We would move the record to deploying after independent evidence of site work, permits, financing, utility capacity, or delivered cooling equipment. Commissioning records, operator confirmation, or measured operation would support an operating status.

A missed 2026 milestone, cancelled agreement, or loss of site control would instead weaken or close the record.

Status is labeled from public evidence. Supplier orders, MoUs, pilots, projects under delivery, and operating sites are not counted as equivalent.
