MHS-11 Substation

The City of Medicine Hat is proposing a new substation (MHS-11) to accommodate the growth and increasing electrical needs in the southwest area of the City and the City’s electric service territory. The proposed substation (the “Project”) will connect to the existing 138 kV transmission line and distribute the electricity to the 13.8 kV distribution system to support the community’s growth.
