Midwest ISO Files Proposal
Nine transmission owners filed a proposal recently with the Federal Energy Regulatory Commission (FERC) that seeks approval for an independent system operator (ISO) to help maintain reliability in the Midwest. Included in the filing are Wisconsin Electric, Ameren, Cinergy, Commonwealth Edison, Hoosier Energy, Illinois Power, Kentucky Utilities, Louisville Gas & Electric and Wabash Valley Power Authority. The proposed entity covers an eight-state region with a service territory of 120,000 square miles. It represents 32,000 miles of transmission circuits and 63,000 MW of electric power with an installed cost of $6 billion.
The filing is the culmination of nearly two year`s work toward the development of a regional ISO to serve the Midwest. “Our expectation is that FERC will act on our application within six months to a year of this filing,” said Dale Landgren, Wisconsin Electric business planning assistant vice president. Once approved, the ISO could be operational within 12 to 18 months.
