Expanding Ranney Falls

See how Ontario Power Generation is adding a new generating unit and powerhouse on the existing Ranney Falls facility, helping to extend the lifespan and efficiency of the station.

Ranney Falls renewal

The new Ranney Falls generating unit will increase the overall capacity of the station by 10 megawatts (MW) to approximately 20 MW overall.

In addition to the new powerhouse and 10 MW unit, OPG is also expanding the existing forebay and tailrace channel, and constructing a new substation to connect with the adjacent Hydro One distribution line. The new unit replaces the existing 0.8 MW unit located in a separate powerhouse that has reached its end-of-life.
