A new Regional Economic Study by ERM Consultants Canada Ltd., a third-party consultant with expertise in socio-economic assessment, shows the TC Energy Pumped Storage Project in southern Ontario would have immense economic benefits locally, regionally and provincially.
The Regional Study Area (RSA) includes Bruce, Grey and Simcoe Counties in Southern Ontario.

TC Energy retained Navigant to perform an economic analysis of the proposed Pumped Storage Project with two focus areas:
The Navigant team completed a rigorous economic analysis and simulation of the Ontario electricity market, calculating the ratepayer and CO2 emissions impacts of the project by running simulations with and without the project.

TC Energy is currently conducting a number of preliminary field studies at the proposed project site to support the feasibility assessment. These studies will help provide insight for TC Energy, the Department of National Defence (DND) and the community as to whether 4th CDTC is a feasible location for a proposed pumped storage facility from an engineering and environmental perspective.
The following provides an overview of the specific feasibility assessments that are currently underway and how these studies will help inform TC Energy’s assessment of the project site.
Underwater depth of Georgian Bay lakebed.
A multibeam echosounder (a type of sonar) is mounted to a boat and pings a beam of sound to the lake floor.
Assesses and supports the design of the intake and discharge structures and provides inputs to 3D hydraulic modelling, which studies water flow in and out of the lake and water turbidity.
Lakebed characteristics such as sediment texture, consistency and smell.
A hand-operated dredge sampler is dropped to the lakebed from a boat. Sediments are then sent to a laboratory for testing.
Supports the design of the intake and discharge structures, provides inputs to 3D hydraulic modelling, which studies water flow in and out of the lake and water turbidity.
Characterizes the overburden materials, bedrock elevations and quality of bedrock. Also establishes groundwater levels.
Boreholes are drilled at various depths into the soil and bedrock with a drill rig.
Supports the design of the reservoir, penstocks and powerhouse by determining what the ground is made of and its characteristics.
