Stinson Generating Station (GS) is located on the Wanapitei River, in the City of Greater Sudbury, approximately 25 km east of the city centre, and approximately 25 km downstream of the Wanapitei Control Dam. Stinson GS is located within the traditional territories of Wahnapitae First Nation, Atikameksheng Anishnawbek First Nation, Nipissing First Nation, Whitefish River First Nation, Henvey Inlet First Nation and Dokis First Nation. The project team has been engaging with the six communities listed above, as well as the Métis Nation of Ontario and the Sudbury Métis Council.
Stinson GS is owned and operated by OPG, and the station is currently 100 years old. To continue to reliably generate clean, renewable energy, Stinson GS is slated for redevelopment. The station will be redeveloped in conjunction with the nearby Coniston Generating Station.
Stinson GS is currently a two-unit hydroelectric power generating facility. The station has a capacity of 5.4 megawatts (MW), and is controlled remotely from the Northeast Control Centre (NECC) in Timmins.
Project information
This redevelopment aligns with the Independent Electricity System Operator’s (IESO) Pathways to Decarbonization report, which highlights the growing need for clean energy investments to meet Ontario’s electricity demands.
The Stinson GS Redevelopment Project is part of OPG’s larger investment strategy which includes upgrading and optimizing many of its existing hydroelectric assets to meet emerging demand as the province continues to electrify. Redevelopment and optimization opportunities include station refurbishments to upgrade facility infrastructure, increase generating capacity, improve operational efficiency, and in some cases, redevelop the entire site.
The Project will see an increase capacity from 5.4 to 6 MW. This investment will ensure that Stinson GS can continue to generate clean, renewable, reliable and flexible energy for generations to come.
Project description
The redevelopment of Stinson GS will modernize critical infrastructure, including:
- A new powerhouse superstructure housing two modern DIVE turbines.
- Replacement of the majority of powerhouse mechanical and electrical equipment
- Refurbishment of existing isolation gates
- New hoist structure and motor installed
Project information
Ontario Power Generation (OPG) is redeveloping the existing Calabogie Generating Station (GS). This Proposed Undertaking involves an Environmental Assessment (EA) under the Ontario Waterpower Association (OWA) Class EA for Waterpower Projects as a Project Associated with Existing Infrastructure. Constructed in 1917, the original station had an installed capacity of 5 megawatts (MW) and is now at its end of life stage. OPG intends to redevelop the site and increase the station’s capacity to approximately 11 MW. The Proposed Undertaking is on the Madawaska River within the village of Calabogie, in the Township of Greater Madawaska, Ontario, as detailed on the map below. OPG does not plan to alter the approved water levels and flows as described in the Madawaska River Water Management Plan (WMP). As such, the anticipated zone of impact for the Project is limited to the immediate area around the station (see shaded/hatched area on the map).
The Class EA process requires OPG to assess the Project to evaluate its potential effects to the environment (positive and negative) and prepare a detailed Environmental Report (ER). That Report is now complete. The conclusions of the ER indicate that any negative environmental effects associated with the proposed Project are minor and/or temporary and can be addressed through appropriate mitigation and monitoring measures that will be implemented during the construction and operational periods of the Project. The new GS at Calabogie will be slightly larger and will help OPG better match water flows with the upstream and downstream generating stations and result in increased utilization of the available water resources, increasing the capacity of the facility to approximately 11 MW. The Project will also allow for an investment into the infrastructure at the facility and produce important local employment benefits and revenues for the Province.
