Available Transfer Capacity Reports Query

The data reported here are the Available Transfer Capability (ATC) limits for the AB-BC and AB-SK intertie lines, and reflect conditions on the Alberta electric grid. The ATC limits might be further impacted by conditions on the British Columbia or Saskatchewan grids. Interested parties should also reference BCTC's OASIS website at http://www.oatioasis.com/cwo_default.htm and SaskPower's OASIS website at http://www.oatioasis.com/spc/index.html.


Using this query, Alberta ATC data can be obtained for historical dates starting Nov 22, 1999, and for forecasted dates up to 12 months into the future. The results can be displayed on-screen or downloaded to a .csv file.
