​We are proposing to replace the three existing transformers in the Garneau substation (located at 11117-85 Ave) to improve reliability and meet increased demand for power in the area.  Two of the new transformers will be replaced in the same location as the existing transformers, while the third transformer will be moved further west to allow for safe access to the equipment during construction and for maintenance.

To accommodate the relocation of the new transformer, the substation yard will need to be expanded. This will involve removing the EPCOR-owned house directly west of the substation and expanding the fence line by approximately 10 metres by 34 metres. To improve security around the substation, we will also be replacing the existing six foot fence with a new eight foot fence. The new fence will look similar to the existing fence. A notification package was distributed in January, 2017, to those residing near the substation.

Project timeline

   
We applied to the AUC for approval of this project in fall 2018. We anticipate receiving a decision from the AUC in fall 2019. 

Proposed construction plan

Start date: Late fall/winter 2019
Estimated completion: Winter 2022

Construction details

​In your neighbourhood

Construction noise

The work will create typical noise associated with construction. We will take measures to ensure we comply with the City of Edmonton's Community Standards Bylaw for Noise Control. If it is necessary to temporarily exceed noise levels, we will work with the City of Edmonton to obtain the necessary permits.

Road closures

Access down 85 Avenue between 112 Street and 111 Street may be limited during some stages of construction. We will work diligently to reduce possible impacts and provide those affected by construction with more detailed information prior to any work starting.

Power supply

No interruptions to power services are anticipated as a result of this project.

On site

Hours of operation

We anticipate our hours of work for this project to be Monday to Friday 7:30 a.m. to 5:00 p.m.; however, occasional evening and weekend work may be required.

Work space

All proposed work spaces for the project will be safe and secure, and construction activities will comply with City of Edmonton bylaws, Occupational Health and Safety requirements, and our strict health, safety and environment program. We do not anticipate any adverse environmental impacts associated with the project.

Please note, the locations of the proposed centre and east transformers replacements have changed since the original project update in January 2017. At that time, we noted that the centre and east transformers would be replaced in place and that the west transformer would move further west within the new substation fence line. Based on futher review, two of the transformers will be located within the larger green box to the east and the third transformer will be located in the green box further west. The new location of the transformer furthest west has not changed since the January 2017 update.

FAQs

​What is a substation and transformer?

A substation is a part of the electrical system that connects two or more power lines. The Garneau substation converts electricity from higher voltage power lines (transmission lines) to lower voltages that can be safely distributed to homes and businesses in the area. This conversion is done using a transformer.
