According to Module C Section 48.3 - Revising LMPs and Prices for Market Implementation Errors sup-part b. MISO has until 5:00 p.m. EST of the calendar day following the contemplation for price correction to post a notice out on OASIS and the public website.
MISO then has 5 calendar days in which to post corrected prices. These revised prices are then used as the basis for settlements. If a Market Implementation Error affecting prices is not caught and remedied before prices are finalized and posted, then it is considered a Continuing Error.
A Continuing Error could be remedied, and the final/revised prices used in the normal course of settlements before the S105, or it could be any time after the final S105 settlement provided it is within the 2-year timebar set forth in Module A Section 12A. In either case MISO will notify Stakeholders of the Continuing Error in the Settlements User's Group (SUG) and if the resettlement amount is > $100k will post a notification out to the public website.
