Companies importing and exporting electricity hold regulatory authorization from the CER and are required to report their export/import activities each month.
Generated electricity not consumed domestically is exported. Electricity trade with United States is affected by prices, weather, power-line infrastructure and regional supply and demand. All these cause trade to vary from year to year. Canada also imports some electricity from the United States. The integrated Canada-US power grid allows for bi-directional flows to help meet fluctuating regional supply and demand.
