Verified project profile
Synapse Olds Data Centre
Synapse proposed a 1 GW data-centre campus in northeast Olds. On August 17, 2026, the AUC denied the proposed 1.4 GW on-site natural-gas power plant because it found the location unsuitable for a project of that scale. Synapse subsequently confirmed that the Olds project will not proceed as proposed. The AUC ruled on the power plant, not the data centre itself, and no replacement site or design has been announced.

Announced data-centre capacity
1 GWTen proposed 100 MW data-centre blocks at full build.
Sources [19]Announced investment
CA$10 billionA proponent estimate repeated in the provincial Major Projects database; no final investment decision was found in the reviewed record.
Sources [18], [16]Proposed campus size
2 million sq. ft.Company-announced capacity across the proposed full campus.
Sources [19], [16]Site parcel
273 acresThe AEPA notice says the proposed thermal power plant would occupy about 20 acres, with the remaining land intended for the data centre and supporting infrastructure.
Sources [3], [8]AUC proceeding
30732, application deniedOn August 17, 2026, the AUC denied Application 30732-A001 because Synapse did not demonstrate that the proposed location was in the public interest. The decision covers the power plant and emergency generation, not the data centre itself.
Sources [8]Environmental application
001-510949, in progressSynapse submitted the EPEA application to Alberta Environment and Protected Areas on July 21, 2026. The Statement of Concern deadline is September 3, 2026.
Sources [1], [5]Municipal permit
No active applicationThe Town of Olds says neither proposed Olds data-centre project has filed a development-permit application.
Sources [1]Employment
2,000 construction; 1,000+ permanentProponent projections, not observed job counts or binding commitments.
Sources [18], [16]Energy and emissions
The AUC denied the proposed on-site power plant and emergency generation on August 17, 2026. Capacity figures below describe the denied application, not approved or operating equipment.
On-site gas generation
1.4 GWTen proposed 140 MW combined-cycle natural-gas plants would supply the ten data-centre blocks.
Sources [7], [6], [13], [8]Grid connection
Not proposedThe power plant is proposed as behind-the-meter self-supply and would not connect to the Alberta interconnected electric system.
Sources [7], [6], [8]Natural-gas connection
Separate pipeline application expectedThe application does not identify final gas suppliers or the pipeline route and capacity. Synapse says the pipeline would be addressed through a future Alberta Energy Regulator application.
Sources [5], [8]Emergency diesel generation
1.8 GW across 600 generatorsThe application pairs 60 generators with each of ten modular blocks. These are proposed backup units, not operating equipment.
Sources [7], [6], [9], [8]Normal-operation air modelling
Compliance predicted for assessed pollutantsThe revised June 12 assessment predicts that modelled normal-operation cases would meet the applicable Alberta Ambient Air Quality Objectives for nitrogen dioxide (NO₂), carbon monoxide (CO), formaldehyde and ammonia. These are model results based partly on developer-supplied or estimated inputs, not measured emissions.
Sources [11], [8]Full-diesel emergency scenario
NO₂, PM₂.₅ and eight-hour CO exceedances predictedCase 4 assumes all ten gas plants shut down and all 600 diesel generators operate. The revised model predicts exceedances of the one-hour nitrogen dioxide, 24-hour fine particulate matter and eight-hour carbon monoxide objectives. The report asks AEPA to exempt temporary, low-frequency exceedances in this scenario.
Sources [11], [10], [8]Proposed stack heights
25.9 m gas; 9 m dieselSynapse increased the proposed gas-generation stack height to 25.9 metres to improve dispersion and retained nine-metre emergency-diesel stacks. These are proposed maximum heights unless a regulator directs otherwise.
Sources [10], [11], [8]Equipment procurement
Not completeSynapse identified preferred suppliers and configurations, but commercial negotiations, final equipment selection and binding procurement remained unfinished in the July 30 response.
Sources [10], [8]Annual greenhouse-gas emissions
Not found in reviewed public sourcesThe revised air-quality assessment addresses local pollutants, not a complete annual CO₂e estimate for the 1.4 GW full build.
Sources [11], [8]Water
The water figures below came from the design accompanying the power-plant application the AUC denied. They are historical developer estimates, not approved allocations, measured use or confirmed demand for a revised project. A separate section of the Town webpage also describes the breakdown differently.
Total normal site demand
Approximately 60 m³/day (60,000 L/day)Synapse's July 30 filing estimates 20 m³/day (20,000 L/day) for plant operations and 40 m³/day (40,000 L/day) for domestic use. These are developer estimates, not approved allocations or measured consumption.
Sources [10], [8]Power-plant operations
Approximately 20 m³/day (20,000 L/day)Synapse describes this as a current maximum design allowance across all ten power blocks, not a final vendor-guaranteed operating value.
Sources [10], [8]Domestic use
Approximately 40 m³/day (40,000 L/day)The developer estimate covers domestic use by on-site personnel and is separate from the plant-operations allowance.
Sources [10], [8]One-time cooling-system fill
900 m³ per building (900,000 L)The Town says each proposed building would require an off-site-supplied one-time fill, or 9,000 m³ (9 million L) across ten buildings.
Sources [14]Town webpage comparison
A conflicting description remainsThe Town page now states the July 30 filing's 60 m³/day (60,000 L/day) total, split between plant and domestic use. A separate section still describes up to 60 m³/day (60,000 L/day) from the municipal system plus 20 m³/day (20,000 L/day) of trucked plant water.
Sources [14], [10], [8]Cooling design
Closed-loop systems proposedThe proponent says both the data centre and gas plant would use closed-loop cooling. Measured consumption will not exist unless the project is built and operating.
Sources [19], [8]Noise
Project-specific noise evidence is shown when it is available. A predicted sound level is not a measurement from an operating facility.
Noise-impact evidence
Assessment and municipal peer review filedThe historical proposal included a noise-impact assessment and a Town-commissioned peer review. The AUC later refused the associated power plant, so these results describe a proposal that will not proceed as reviewed.
Sources [13], [8]Emergency-generator noise choice
75 dBA option exceeded Rule 012 at several receptorsSynapse proposed 75 dBA emergency generators rather than a quieter, more expensive 65 dBA option. It said it would follow an AUC condition requiring the quieter units, but no such approval condition was issued because the plant was refused.
Sources [10], [9], [8]Partial-failure scenarios
Not modelledThe noise assessment evaluated defined cases, not every possible mix of gas and diesel generation. Synapse proposed later modelling plus boundary monitoring, alarms, load reduction, and shutdown controls; those measures were not confirmed as enforceable conditions.
Sources [10], [8]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 and Métis geography
Treaty 7 regionThe Town of Olds identifies the area with the Blackfoot Confederacy, Tsuut'ina First Nation, Stoney Nakoda Nations and Métis Nation of Alberta Red Deer Métis District 3. This is geographic context and does not by itself establish project-specific consultation, effects or positions.
Sources [17]Approval and public process
The AUC power-plant review ended with a denial on August 17, 2026, and Synapse says the Olds project will not proceed as proposed. The AEPA environmental review and any future Town development-permit process are legally distinct.
Power-plant application
Denied by the AUCThe AUC denied Application 30732-A001 on August 17, 2026, finding that Synapse had not justified locating a power plant of this scale so close to the surrounding community.
Sources [8]Developer response
Olds project will not proceed as proposedSynapse confirmed after the AUC decision that the Olds project will not proceed in the form reviewed. It said it would assess other opportunities in Alberta, but did not announce a replacement site or design.
Sources [20]Residential proximity
Approximately 30 m at the nearest pointThe AUC decision says the site boundary is about 30 metres from the first row of properties and that more than 700 residences are within 800 metres.
Sources [8]Public participation
About 1,500 statements; 919 granted standingThe AUC described the participation level as unusually high. It did not treat the number alone as determinative, but said it demonstrated significant community concern about the location.
Sources [8]Environmental application
AEPA review in progressApplication 001-510949 is being reviewed under the Environmental Protection and Enhancement Act. This is separate from the AUC power-plant proceeding and the Town's future development-permit review.
Sources [1], [5]Public input
Statements of Concern due September 3, 2026The Town's current page gives September 3 based on the last notice publication date. The posted notice PDF still shows August 20.
Sources [1], [3]Data-centre application
Not filed with the TownNo municipal development-permit review or decision can occur until an application is submitted.
Sources [1], [6]Municipal land use
Data centre is a discretionary useThe site is in the Light Industrial District, where the Town would decide any data-centre development-permit application as a discretionary use. The denied application treated the self-supply power plant as an accessory use, but the AUC independently refused that plant.
Sources [6], [1], [8]First AUC filing
Closed for deficienciesThe AUC closed the first application on March 6, 2026 because the submission was incomplete. The Town explicitly distinguishes this from rejection after a full merits review.
Sources [1]Town participation
Support in principle consideredThe Town supported the project in principle. The AUC considered that support and the project's potential economic benefits, but found the proposed power-plant location was not in the public interest.
Sources [6], [8]Developer engagement
Three rounds reportedThe Town records engagement beginning January 26, an April 1 open house attended by about 30 people, and June 10 consultations attended by about 40.

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.
- Synapse has not announced a replacement Olds proposal, another Alberta site, a revised power design, or whether it will seek permission to appeal the AUC decision.
- AEPA has not issued a decision on EPEA Application 001-510949.
- No development-permit application, municipal approval or construction authorization for the data-centre campus has been filed or issued.
- A final investment decision, committed hyperscale customer, financing structure and binding construction schedule were not found in the reviewed public record.
- Natural-gas suppliers, the pipeline route and capacity, and the fuel-interruption plan were unresolved in the denied application. No replacement power-supply or pipeline plan has been published.
- Final equipment selection and binding procurement were incomplete when the AUC denied the application. No revised equipment or emergency-generator noise design has been published.
- A complete annual greenhouse-gas estimate for the denied 1.4 GW power-plant design was not found in the reviewed public sources. No estimate for a revised design has been published.
- The Town's March air-quality peer review assessed the earlier February report for the design that was later denied. ADCW has not located an independent Town review of the revised June 12 assessment.
- The Town webpage gives two conflicting water-demand descriptions tied to the design accompanying the denied application. Neither should be read as an approved allocation or confirmed demand for a revised project.
- The proposed Community Benefits Program has not been publicly defined as a binding amount, formula or governance structure.
- The denied application estimated decommissioning costs at approximately CA$290 million and proposed delayed security beginning in year 10. Those terms were not approved, and no revised closure or security plan has been published.
- The Town estimates CA$5–7 million in annual municipal property tax at full build, but the taxable assessment will not be known unless facilities are built and operating.
- The provincial Major Projects map explicitly labels its Olds coordinate a placeholder. ADCW instead uses the site coordinates and legal location published in Synapse's construction emergency response plan.
