Project Overview

Hydro One initiated a Class Environmental Assessment in February 2020 to refurbish and expand our Tillsonburg Transformer Station (TS) and refurbish the existing 115 kilovolt transmission line between Tillsonburg TS and Cranberry Junction (JCT), as shown on the map below. The proposed project is subject to the Class Environmental Assessment for Minor Transmission Facilities (Hydro One, 2016), in accordance with the Ontario Environmental Assessment Act. The Environmental Assessment is a streamlined process to ensure that transmission projects that have a predictable range of effects have feasible environmental mitigation and/or protection measures in place.

Equipment nearing its end-of-life must be replaced to ensure a continued reliable supply of electricity. To accommodate the upgraded equipment, the station needs to be expanded by approximately 10 metres to the east and approximately 20 metres to the west at the station entrance. Other work includes:

  • Replacing the existing three-pole wood structure on the existing corridor and the installation of one or two additional wood pole structures to the northeast are also required

  • The modification and/or replacement of select wood pole structures, and the replacement of conductor wires and insulators along the existing right-of-way between Tillsonburg Transformer Station and north to Cranberry Junction

  • Some vegetation removal is required near the station entrance and on the east side of the station to accommodate the expansion work and installation of new structures. Hydro One is committed to looking for opportunities to replant in this area following construction.
