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.


Rate changes were processed to incorporate the following:


Schedule 2

  • Per Docket ER20-6, ALCOA’s Warrick Unit 4 was added to the SIGE pricing zone.
  • Per Docket EL19-56, a generator specific revenue requirement replaced Hoosier Energy’s stated rate in the HE pricing zone.
  • Per Docket ER19-2662, Vistra’s Duck Creek generator was retired in the AMIL zone.
  • Per Docket EL 19-49, Cooperative Energy’s Batesville and Grand Gulf revenue requirements were reduced in the Entergy Mississippi pricing zone.


 Overall the MISO Schedule 2 rate decreased by 0.42%.


These changes are effective December 1, 2019.
