What is the history of Ranney Falls Generating Station?

The Ranney Falls Generating Station (GS) site was formerly leased by the Federal Government to the Seymour Power Company. With its purchase of the Seymour Power Company in 1916, the rights to the site were acquired by the Province. Ranney Falls GS G1 and G2 units were commissioned in August 22, 1922 and September 2, 1922, respectively. Unit G3, which started operation in 1926, was acquired by the Hydro-Electric Power Commission of Ontario from the Quinte and Trent Valley Power Company in 1937. Ranney Falls GS was transferred to Ontario Power Generation Inc. on April 1, 1999, and is managed by the Central Hydro Plant Group with remote operation from the North Bay Control Centre and maintained by the Campbellford Service Centre.

Why is OPG considering this Project?

Ranney Falls GS consists of two powerhouses. The main powerhouse contains the G1 and G2 turbine units, each operating at approximately 5 megawatts (MW) during maximum flows. A secondary powerhouse, commonly referred to as the "Pup", contains the 0.8 MW G3 unit that has reached its end-of-life. Based on a Feasibility Study for the proposed Ranney Falls G3 Project, it was determined that a new G3 unit of up to 10 MW could be installed at the Ranney Falls GS site. This would increase total station capacity to up to approximately 20 MW. The "Pup" powerhouse would be decommissioned.

The proposed Project will improve the efficient use of the available hydroelectric potential at the site, reduce greenhouse gas emissions and increase the amount of clean renewable energy from OPG's Central Hydro Plant Group.

Is there government policy support for this Project?

The Panel on the Future of the Trent-Severn Waterway (TSW) concluded that the development of renewable energy resources is a sound public policy goal and supported a vigorous effort to pursue green energy generating potential along the TSW. Moreover, the proposed Project is consistent with the Provincial Policy Statement, which recommends that the use of existing infrastructure and public service facilities should be optimized, whenever feasible, before consideration is given to developing new infrastructure and public service facilities.

What is the schedule for the Project?

The project can move to construction once the project has been fully defined through the environmental assessment process, detailed engineering review and all approvals have been received.
