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.

Ranney Falls upgrades require extra caution for boaters ahead of 2022 recreational season

The spillway at Ranney Falls GS showing dangerous water flowsAhead of the Trent-Severn Waterway recreational boating season, we’re advising residents and tourists to expect higher river flows and faster-moving waters both above and below our Ranney Falls Generating Station (GS) on the Trent River in Campbellford, Ontario.

Recent upgrades at Ranney Falls GS allow for more efficient passing of water through the facility’s spillways and generators, increasing the velocity of river flows around the dam. The change will occur near the beginning of the 2022 recreational boating season. Even boaters with experience on these waterways are advised to take additional precautions this season and beyond.

Remember, dry or calm riverbeds below dams may look safe, but they can quickly change into rapidly flowing waterways with dangerous currents. Please obey all signs, buoys, booms and barriers.
