Wawa Transformer Station (TS) Expansion

Hydro One has completed a Class Environmental Assessment (EA) to expand its existing Wawa Transformer Station (TS), located northeast of Anjigami Lake on Anjigami Lake Road, southeast of the Municipality of Wawa. This station expansion is required in order to connect the new East-West Tie transmission line to the station.

As part of this project, the following work is required:

• Installation of new electrical equipment such as circuit breakers and disconnect switches;
  

• Reconfiguration of existing electrical components to establish connection with the proposed new line; and 
  

• Installation of a new relay building, which would house electronic devices critical for safety, reliability and security of the power system.
  

To accommodate this work, the existing Wawa TS will be expanded by approximately half a hectare to the north. 

Hydro One completed the Environmental Study Report (ESR) on September 27, 2019.

Project Location & Profile

Wawa TS is located northeast of Anjigami Lake on Anjigami Lake Road, approximately 20 kilometres southeast of the municipality of Wawa. Hydro One has identified an additional small expansion along the western side of the existing station fence which is necessary to accommodate site grading.  This additional portion of land is on Hydro One-owned property and is identified on the site map.  Affected parties have been consulted and no concerns were raised.  Click here to view the project map.
