Transmission Settlements and Pricing

The Monthly Transmission Settlements process financially settles Transmission Customers’ use of the MISO transmission system and our mandated, non-competitive Ancillary Services. Customer charges for transmission and Ancillary Services are calculated based upon the FERC-approved Tariff, and collected funds are distributed to Transmission Owners and providers of the mandated Ancillary Services. 

Transmission Settlements follows a calendar-month billing cycle by which MISO determines what charges Transmission Customers have incurred and the distribution of revenue to Transmission Owners and/or generators.  Customers also may count on us for technical assistance and support on MISO Transmission rate-related matters. Our processes provide non-discriminatory reviews of Attachments O, GG, MM, SS, and ZZ submissions annually.
