Home Planning Interregional Coordination

Interregional Coordination

IR Map

MISO works with its neighboring transmission planning regions to develop mutually agreeable methods for allocating the costs of transmission facilities that benefit more than one region. MISO coordinates with Southwest Power Pool, PJM Interconnection and the Southeastern Regional Transmission Planning Region. MISO and its seams partners meet multiple times each year to exchange information. 

PJM neighbors MISO to the northeast and is the regional transmission organization and independent system operator for members in Delaware, Illinois, Indiana, Kentucky, Maryland, Michigan, New Jersey, North Carolina, Ohio, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia.
