FERC Favors Regional Solutions to Loop Flows
The Federal Energy Regulatory Commission (FERC) has opened a paper hearing on electric loop flow issues arising from the unscheduled flow mitigation plan filed by the Western Systems Coordinating Council (WSCC) (Docket No. ER95-215-000). WSCC members have endured loop flow problems in their region for over 20 years. Expanding on previous ideas, the plan includes the coordinated operation of "controllable devices," such as phase-shifting transformers, that can reduce the level of unscheduled flow by altering power flows on parallel alternating current transfer paths.
