Calgary data-centre market reference

Calgary has an operating colocation market represented here by Equinix, eStruxture and Rogers Business. Equinix publishes CL1, CL2 and CL3. eStruxture publishes CAL-1 and CAL-2, plus the developing CAL-3 project in Rocky View County. Rogers publishes a city count of three data centres. These records support enterprise, network and managed infrastructure needs at a scale distinct from the largest new grid applications.

The map places facilities at generalized city or community points. It does not disclose the electrical point of connection or exact site. For a new development, the relevant geography is the transmission and distribution network, available land, generation context, fibre routes and municipal approvals. Use the public facility list to understand operators, not to infer a serviceable megawatt total.

AESO reports that large data-centre requests rose beyond the capacity that could be connected quickly. Its interim 1,200 MW allocation was assigned to two projects, and later requests moved into subsequent work. A new Calgary proposal should use the current large-load program, not assume that the earlier limit is open capacity or a first-come queue.

The system access path requires project data, studies and commercial obligations. Depending on the design, a project may also consider on-site generation or new supply. Those options change the regulatory and technical analysis. A public announcement about land, generation discussions or a connection request should not be presented as an executed load contract.

AESO's data-centre requirements address rapid ramps, load variability, power-electronic controls and sensitivity to voltage and frequency. A facility model needs more than maximum MW. It should describe staged loading, UPS and rectifier behaviour, ride-through, fault response, recovery, power factor and interaction with backup generation. The system operator can place project-specific capabilities in the functional specification.

For Calgary designers, electrical control sequences should be developed with the grid study rather than after it. A fast transfer or simultaneous restart across many blocks can create a different system event from steady operation. Commissioning plans also need controlled load steps and clear coordination with the utility and AESO requirements.

Alberta's wholesale market attracts attention, but a large facility also pays or funds transmission, distribution, losses, connection work and other system obligations. The delivered cost changes with location, load factor, market exposure and commercial strategy. A historical pool-price average cannot serve as a complete Calgary data-centre rate.

Compare fixed and variable energy arrangements, connection contributions, network reinforcement, commissioning delays and the value of any paired generation. Keep assumptions dated. A project with an attractive energy scenario can still fail if the connection schedule, ramp constraints or required facilities do not match the development plan.

Existing Calgary colocation may provide migration staging, network access, recovery space or a smaller production footprint while a new campus is developed. Confirm the specific services and routes with the operator. A same-city listing does not prove a private connection or common utility supply. The directory labels nearby context without asserting those relationships.

CAL-3 illustrates why operating state matters. The record is based on a dated operator announcement and remains in development until a later source confirms operation. A planned commissioning period is not treated as an opening date. The change ledger should capture the transition when supported by new evidence.

For an operating facility, ask for current available power, density, cooling envelope, UPS and generator topology, maintenance windows, carrier list and expansion rights. For a new campus, add the exact system-access milestone, allocated load, study status, required grid upgrades, generation assumptions and commissioning ramp. Separate each answer by source and date.

The facility list below is a sourced market inventory, not a capacity forecast. Unknown specifications remain open. Pages only re-enter the sitemap in reviewed batches of 20 or fewer after they carry sourced substance and a dated event. That rule prevents numbered city-level records from becoming thin search pages while preserving them for transparent coverage work.
