Transmission Pricing 

Users of the MISO Transmission System, or Transmission Owners (TOs), pay transmission rates that are developed and maintained by the Transmission Pricing group for select Tariff Schedules. Customers also may count on us for technical assistance and support on Midwest ISO Transmission rate-related matters.

When TOs submit completed Attachments O, GG, MM, SS, and ZZ via e-mail, the Transmission Pricing Group reviews, approves and uses them to help calculate Transmission Rates for settlement of transmission charges and the distribution of transmission revenue. By using an interactive review process, we ensure issue awareness, and encourage input from TOs. Our process provides non-discriminatory reviews of Attachments O, GG, MM, SS, and ZZ submissions annually. And, for further transparency, you'll find all finalized documents on this website (See the table below for links to data).
