Home Markets and Operations Settlements Transmission Settlements and Pricing

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.
