Central Operations in the Community

Headquartered in North Bay, OPG's Central Operations has facilities extending across the region to Merrickville, and service centres in North Bay, Gravenhurst and Campbellford. We operate 26 hydro stations and 23 control dams on nine river systems, including the Beaver River, Muskoka River, Sturgeon River, South River, Mississippi River, Trent River, Rideau River, Severn River, and Wanapitei River. All these stations are all remotely operated and monitored 24/7 by our control room in North Bay. 

A number of OPG’s central Ontario facilities have been part of the local community for more than one hundred years. This includes our oldest facility, the Sills Generating Station (GS), which started production in 1900. Other legacy generating stations like Big Chute, Frankford, Healey Falls, Eugenia, Seymour, and McVittie were built between 1900 and the 1940s. Churning out clean, renewable power for local communities and the mining, cement, and pulp and paper industries, they also helped attract new manufacturing and processing industries.


  • Central Operations facilities have a combined capacity of 124 MW (megawatts).  
  • At 550 feet, Eugenia GS has the highest head of all OPG hydroelectric generating stations. Head is the vertical change in elevation between the reservoir at the top and the tailwater at the bottom.

Corporate Citizenship

As part of our commitment to North Bay and the surrounding communities, OPG’s Central Operations has supported more than 60 local not-for-profit initiatives through our Corporate Citizenship Program. Our initiatives focus on the following categories: education, community, and environment. Current or past partnerships include Science North, Métis Nation of Ontario, North Bay Regional Health Centre, and the Town of Gravenhurst.

Safety First

OPG reminds you to please pay attention to all fencing and signage near our hydro stations and dams, and to Stay Clear and Stay Safe. If you are interested in touring one of our facilities, please contact Central’s community representative (see below).
