The Independent Market Monitor (IMM) is an organization or individual retained by MISO to impartially implement Market Monitoring and Mitigation (MMM) business practices. The IMM reports directly to the MISO Board of Directors and monitors activities of Market Participants and Local Balancing Authorities without interference from MISO or state regulatory agencies. Currently, MISO retains Potomac Economics as its Independent Market Monitor.
As the Independent Market Monitor to MISO, Potomac Economics continuously receives data which is used to evaluate the performance of the markets and identify conduct by market participants or MISO that may compromise the efficiency or distort the outcomes of the markets. In addition to real time monitoring, Potomac Economics produces reports assessing the competitive performance of the markets. These reports are produced on both a seasonal and annual basis. Ad-hoc reports are produced to evaluate specific market issues as needed.
