8.3 THE INTEGRATED NORTH AMERICAN GRID There are over 35 electricity transmission interconnections between the Canadian and U.S. power systems, forming a highly integrated grid. Introduction to the Integrated Grid and Trade Although there are several east-west interconnections between Canadian provinces, the majority of electricity trade occurs on a north-south basis between Canadian provinces and U.S. states. Every Canadian province along the U.S. border is already electrically interconnected with a neighbouring U.S. state or states, with many provinces boasting multiple international connections.
Integrated North American Grid Integration is set to continue expanding, with multiple cross-border transmission projects currently in various stages of development. Integration of this type across a large geographic area results in an electricity grid that is more flexible, reliable, and secure—on both sides of the border. Below is a map of major Canada–U.S. Transmission Interconnections.
Electricity Canada believes that there is no better example of the promise and benefit of electricity-related integration between nations than that of Canada and the United States.
