After more than two years of planning and training, MISO integrated a four-state region of the electric grid across the South into its existing footprint in the Midwest. The change in control, or "cutover," extends MISO's operational and market footprints from the Gulf of Mexico all the way to Manitoba, Canada. In total, MISO now manages a combined footprint of 65,280 miles of transmission with total electric generation capacity throughout MISO of approximately 196,000 MW. The integration added 10 new transmission owning companies, six local balancing authorities and 33 new market participants from Mississippi, Louisiana, Arkansas, Texas and Missouri to MISO.
