FERC Tells Grid Operators to Settle Differences

LCG, January 7, 2003-The Federal Energy Regulatory Commission has advised the Midwest ISO and PJM Interconnection to resolve issues of transmission rates between grid areas.

Customers of the Midwest Independent System Operator and PJM Interconnection LLC face charges when moving electricity from one transmission system to the other.

FERC has urged the transmission operators to come to some type of settlement regarding these rates, and FERC Chairman Pat Wood has suggested that a cost-of-service formula could be used to determine rates. The two operators plan to form a single large grid by October of next year, serving over 20 states and some of Canada.

Last month a FERC Administrative Law judge threw out rate-related testimony submitted by various power industry agencies in regards to the transmission operators. DTE Energy Co., Detroit Edison, Wisconsin Public Power Inc., Indiana Municipal Power Agency, Southeast Michigan Systems, and International Transmission Co. submitted evidence.

FERC officials reinstated some of that evidence yesterday, part of which addressed claims that those controlling transmission overcharged in order to make up for lost revenue.

If Midwest ISO and PJM fail to come to some agreement with customers, a FERC judge will rule by Febraury 28 on the case.
