Markets and Operations 

As one of the world’s leading Regional Transmission Organizations and the largest geographical organization of its kind, MISO provides independent, equal and non-discriminatory access to the electric transmission system. MISO's efficient market operations ensure and support increased grid reliability.  

In 2015, those efforts provided between $2.1 billion and $3.1 billion in regional benefits, driven by enhanced reliability, more efficient use of the region’s existing transmission and generation assets, and a reduced need for new assets. Find out more from our annual Value Proposition study.
