OPG announces 10 MW upgrade to Ranney Falls

Canadian utility Ontario Power Generation has announced a rehabilitation program that will more than double the capacity of its 10-MW Ranney Falls hydropower plant.

The US$20 million project will replace an existing 800 kW turbine that was installed in 1926. That unit, known by OPG as the “Pup”, is located in a separate powerhouse and will be replaced by a new 10 MW unit.

“The Ranney Falls generating station is continuing its century’s old legacy of hydroelectric excellence,” said Lou Rinaldi, Member of Provincial Parliament for Northumberland-Quinte West. “This new generator will breathe new life and double its generating capacity. We are committed to maximizing our hydroelectric resources across the province, and today’s announcement is an excellent example of that plan.”

The upgrade project also includes the construction of a new powerhouse, an expansion of the existing forebay and tailrace, and installation of a new substation. OPG said it expects the work to create 70 jobs.

The new generating unit is scheduled for operation beginning in 2020.

Ranney Falls was constructed in 1922 by OPG’s predecessor, the Hydroelectric Power Commission of Ontario, and is located on the Trent River adjacent to Lock No. 12 on the Trent-Severn Waterway.
