FERC Rules to Preserve Charges Between Transmission Systems

LCG, April 1, 2003The Federal Energy Regulatory Commission decided grid operators can charge fees to transfer electricity from one operators transmission lines to another through their own.

The case surfaced as PJM Interconnection and Midwest Independent System Operator applied to join their respective service territories. Midwest ISO serves some Southern States as well as several Midwest states including parts of Illinois, Indiana, Iowa, Kentucky, Maryland, Michigan, Minnesota, Ohio, and Wisconsin. PJM serves mid-Atlantic states.

While some utilities have claimed that such "through-and-out" charges are unfair and hamper competition, FERC ruled that the two transmission operators will be allowed to continue charging fees to send electricity through their transmission lines from another operators lines.

FERC Judge Herbert Grossman made the ruling yesterday, although FERC commissioners can revise Grossmans ruling. The judge also noted that if FERC throws out such fees, a new fee should be instated in such a way as to not allow utilities to shift costs to ratepayers.
