Woodcroft substation

EPCOR is responsible for building, maintaining and upgrading the electric transmission and distribution system in Edmonton.

Part of this system includes substations, which convert electricity from higher voltage power lines (transmission lines) to lower voltages that can be safely distributed to homes and businesses in the area.

Project overview

The existing transformers in the Woodcroft Substation (located at 11819 142 Street) are reaching their end of life and need to be replaced. We are planning to replace three existing 40 MVA transformers with three new 30/40/50 MVA transformers. These new transformers will help improve reliability and meet increased demand for power in the area.

If approved by the Alberta Utilities Commission, we will begin replacing the transformers in stages over the next three years starting in spring 2026. The new transformers will be replaced in the same location as the existing transformers.
