Verified project profile
Keephills Data Centre Development
TransAlta, CPP Investments, and Brookfield propose a data centre at Keephills, starting at about 230 MW and potentially growing to 1 GW. Land-use changes allow a proposal to move forward, but do not approve the buildings. The reviewed sources do not confirm a construction start, final water needs, or noise levels at nearby homes.
Project facts
Core scale, approval, employment, and schedule information, labelled by the type of evidence available.
Who is behind it?
TransAlta, CPP Investments, and BrookfieldTransAlta would provide the land and power. A future data-centre operator or customer has not been confirmed in the reviewed sources.
Sources [5]How large could it become?
Up to 1 GW, if expansion proceedsThe July company filing still describes a conditional agreement, not a final commitment to build the full project.
Sources [6]Where would the buildings go?
Final layout not confirmedThe map marks the Keephills industrial area, not an approved building location or campus boundary.
Sources [1]When would it open?
No confirmed opening dateGrid-planning dates below are not a construction or operating schedule.
Sources [3], [4]Energy and emissions
The first stage has a grid-load contract. The larger figures describe requests and possible expansion, not electricity already being used.
First-stage grid allocation
230 MW under a signed load contractAESO, Alberta's grid operator, lists P3083 in its completed first allocation round. The project must still complete the connection process.
Sources [2]All three grid requests
861 MW requested in totalAugust list: P3083 has 230 MW at Stage 2; P3095 has 466 MW at Stage 2; P3152 has 165 MW at Stage 1. These are connection-process stages, not construction stages.
Sources [3]Dates in the grid list
2027 and 2028 for the first 230 MWP3083 is split into 115 MW dated January 1, 2027, and 115 MW dated March 27, 2028. P3095 and P3152 have dates under review. None is a guaranteed opening date.
Sources [3]The power station already on site
861 MW of existing gas generationThis is a separate figure from the grid requests. TransAlta has not confirmed that all this power would serve the data centre. ADCW does not count it as newly proposed generation.
Sources [7], [5]Electricity use and air emissions
Project-specific totals not publishedThe final supply design and backup generators are not confirmed. Capacity alone does not establish annual electricity use or emissions.
Sources [6], [4]Water
The unanswered question is how much water this project would need, and where it would come from. Existing water infrastructure does not establish an allocation for the data centre. [5]
How would the servers be cooled?
Cooling design not confirmedThe reviewed project disclosures do not establish whether cooling would consume water or how much it would need.
Sources [5], [4]Water available to this project
No project allocation verifiedTransAlta points to existing water infrastructure. That does not confirm the data centre's water source, permitted volume, or effects on other users.
Sources [5]Water leaving the site
Wastewater and drainage plans not confirmedIt is not yet clear how used water, rainwater, or snowmelt would be handled.
Sources [4]Noise
There are no verified project-specific sound predictions here to show what neighbours might hear. That gap is not evidence that the project would be quiet.
What could neighbours hear?
Predicted sound levels not foundThe reviewed sources do not provide a project-specific noise study or numerical predictions at nearby homes.
Sources [1], [4]Noise controls
Final measures not confirmedEquipment choices, sound barriers, and operating limits have not been verified. Their effectiveness cannot be assessed without a design and study.
Sources [4]Indigenous context
Data centre projects sit within treaty territories and places with longstanding First Nations and Métis connections. This section brings together the public record on treaty geography, Indigenous ownership, consultation, and community concerns. Treaty boundaries alone cannot tell us which communities may be affected or how they view a project.
Treaty geography
Treaty 6 territoryThis describes location, not consent or any Nation's position on the proposal.
Sources [8]Project-specific Indigenous engagement
Outcomes not confirmedThe reviewed project disclosures do not establish participating Nations, concerns, agreements, or consultation outcomes.
Sources [4]Approval and public process
Permission to use land for a data centre is different from permission to build one. The site plan and development permit are still separate decisions.
What has Council approved?
Land-use changes, not the buildingsCouncil passed the planning amendments on September 4, 2025. A master site development plan and development permit are still required.
Sources [1]Has a development application arrived?
Not according to the County's posted statusThe page was last updated March 4, 2026, and checked August 31. It still says no development-stage applications have been received; this is not a new August statement from the County.
Sources [1]How can residents take part?
Watch for site-design and permit noticesThe County says it will post application materials and engagement opportunities on its project page. No new meeting date or comment deadline was found.
Sources [1]Timeline
Observed decisions and future dates are kept distinct; projected milestones may change.
- Public record
Council approved the land-use and planning changes. [1]
- Proponent statement
TransAlta's quarterly filing still described development as conditional on approvals and final agreements. [6]
- Public record
AESO's published list showed three related requests totalling 861 MW, with dates for two requests under review. [3]
What we still don't know
Some details have not been made public or remain unresolved. We keep those gaps visible and update them when reliable information becomes available.
- Final business agreements, customers, a construction start, and an opening date have not been confirmed.
- The approved building layout, total building area, and permit conditions are not available in the reviewed sources.
- The full power-supply plan, new equipment, and project-specific annual emissions remain unclear.
- Water demand, supply permission, and wastewater arrangements have not been confirmed.
- Predicted noise at nearby homes and final noise-control measures were not found.
