Sources and method

Flow comes from AESO interface readings. Each value is shown with its operator and source time; direction is normalized from that operator’s sign convention toward or away from AESO. A rating describes the equipment; an operator’s posted directional limit, when available, is a separate operating value. The map point identifies a sourced terminal or crossing where available, or a representative connection point; it does not trace the full route.
