"We remain dedicated to Illinois and to securing a cleaner energy future. We are optimistic that the IPCB will grant the requested relief." AER is also working closely with the PJM Regional Transmission Operator (PJM RTO) and the Midwest Independent Transmission System Operator (MISO) to remove barriers preventing downstate Illinois generators from moving power to the northern part of the state where prices are higher. "Solving this singular issue would be a first step in resolving our financial challenges," said Sullivan. "It is time for the Federal Energy Regulatory Commission to direct PJM and MISO to solve this problem." AER is the holding company for the merchant generation business of Ameren Corporation (NYSE: AEE ). AER generates power and sells it to wholesale and retail customers throughout the Midwest.
