A municipal transformer station (MTS) “steps down” the voltage of the electricity being delivered by a high-voltage transmission line to a lower voltage that is suitable for distribution to local customers. Distribution lines are generally on poles along the road allowance and may also be underground in some areas.

The proposed site is 195 Boychuk Dr, Cambridge.

GrandBridge Energy is planning the development of a new transformer station to support growing electricity demand and ensure a safe, reliable power supply for our communities.

The planning of this project will follow the Class Environmental Assessment for Transmission Facilities (Class EA for TF) under the Ontario Environmental Assessment Act.  This process applies to transmission infrastructure projects that are carried out routinely and will feature 16 step screening criteria. View the criteria here.

1. Noise: An acoustic assessment will be completed. Low sound level transformers will be utilized on this project. Minimal noise impact is expected.
2. Traffic: There will be construction traffic tentatively throughout 2027 and the first half of 2028. There will be little traffic once the transformer station comes into service.
3. Environmental: The Class EA Screening process will be followed to assess and confirm that there will not be impacts on air, water, land and natural resources. A preliminary perspective includes:

• Air – There will be no material air emissions.
• Water – An Environmental Compliance Approval will ensure that stormwater and spill containment measures are in place to protect adjacent natural features, including the wetland.
• Land – This project will have a small land use change from agriculture to energy infrastructure with incremental landscaping, fencing and egress.

Yes, GrandBridge Energy is consulting with Indigenous communities about this project.

During the construction phase of this project, you can expect activities similar to that of a typical construction site.

• Earthworks to remove topsoil and prepare the site.
• Water/sewer servicing.
• Installation of concrete enclosures and electrical equipment. Construction of a building.
• Powerlines will be connected from the station to Boychuk, tying into the existing electrical grid.
• Landscaping and fencing.

There are no planned outages for this project.
