Project Need and Description
Parts of the high-voltage electricity system in Guelph were installed starting in 1910 and require upgrades to keep pace with the economic growth and development in the area. This need was identified by the Ontario Power Authority (OPA)and confirmed by the local utility Guelph Hydro. Conservation and demand management and distributed generation will, however, continue to play a role in the long-term electricity plan for the community. See OPA's integrated solutions for Guelph (2MB).
To ensure that Guelph Hydro customers continue to receive a safe and reliable supply of power, Hydro One proposes three alternatives to address the area's needs:
Alternative 1
- Build a new transformer station (TS) with two 230-115 kV transformers on a new site within the study area.
- Replace approximately 5 km of an aging 115 kV transmission line between Campbell TS and CGE Junction with a two circuit 230 kV line. The line would operate initially at 115 kV.
Alternative 2
- Install two 230-115 kV transformers at the existing Cedar TS site.
- Replace approximately 5 km of aging 115 kV transmission line between Campbell TS and CGE Junction with a two circuit 230 kV line. The line would operate at 230 kV.
Alternative 3 (new)
- Install a new switching station at the Guelph North Junction.
- Replace two of the existing transformers at Cedar TS.
- Replace approximately 5 km of aging 115 kV transmission line between Campbell TS and CGE Junction with a two circuit 230 kV line.
No changes to the transmission line between CGE Junction and Cedar TS are required.
Construction of the proposed facilities must also be approved by the Ontario Energy Board (OEB). All activities will follow Hydro One's Environmental Guidelines for Construction and Maintenance of Transmission Facilities.
