Definitions for "Loop Flow"
The movement of electric power from generator to load by dividing along multiple parallel paths; it especially refers to power flow along an unintended path that loops away from the most direct geographic path or contract path.
The difference between scheduled and actual power flows on electric transmission lines.
Loop flows are unscheduled flows of electricity that result because electricity obeys the laws of physics and doesn't strictly obey system operators. A well-known loop flow that affects Ontario occurs around Lake Erie, entering Ontario at Niagara and exiting Ontario through our ties to the United States at the Michigan border. Hydro One and Detroit Edison are presently upgrading the electrical interconnection between Ontario and Michigan. This project includes equipment designed to control this loop flow.
