The Illinois Commerce Commission announced that Commonwealth Edison Company’s customers will see $318 million in benefits as a result of a settlement concerning the allocation of costs for transmission facilities in the PJM Interconnection LLC’s footprint, according to the agency’s Sept. 25 press release. The settlement, approved by the Federal Energy Regulatory Commission, is a result of negotiations after two court rulings and remand proceedings before FERC against a 2007 order which directed PJM to allocate 100 percent of the costs on a load-ratio share basis to merchant transmission facilities and zones of the responsible customers. The commission said it has fought since 2005 to protect Illinois ratepayers from bearing the costs of certain large transmission projects without demonstrating corresponding benefits.
