Data source: AESO Interchange ATC API (itc.aeso.ca/itc/public/api/v2/interchange, dataType=ATC). These are the same curves that back your Excel "Provincial Available Transfer Capacity" sheet – you can append additional derived columns (TRM, expected provincial flow, "we can" MW, etc.) in your own model or a future backend job without introducing synthetic inputs.
