The Federal Energy Regulatory Commission (FERC) has issued its final order in response to complaints filed with the agency about the outcome of an energy capacity auction conducted last spring that resulted in huge price spikes for Midcontinent Independent System Operator (MISO) customers in Illinois. FERC agreed with the Illinois Attorney General – and Ameren Illinois, a complainant in the case filed by the state and other watchdog groups and utilities – that the process used to set capacity prices in MISO is no longer just and reasonable and must be modified prior to the next MISO capacity planning auction. This ruling could lead to short-term rate relief for Ameren Illinois customers.
“Our position has always been that the process for establishing capacity costs should be fair and just, and not unduly burden Ameren Illinois customers,” said Richard J. Mark, president of Ameren Illinois. “We have spent the last several months appealing to FERC on behalf of utility customers in central and southern Illinois in support of a review of the MISO auction. FERC’s ruling provides an encouraging sign that issues with the capacity auction process are being addressed, and that our customers can expect stable prices in the future.”
