SPP inadvertently omitted \nrevisions to the rate sheet for the Upper Missouri Zone to add references to Schedule \n14 and Incremental Market Efficiency Use revenues. SPP proposes the following \nrevisions: \n \nPoint-To-Point Transmission Service and Conditional High Impact Large \nLoad Service Revenue Crediting for Point-To-Point Rates \nRates for Point-To-Point Transmission Service under this Attachment T shall \nreflect any adjustments for Schedules 7, and 8 revenues, 14, Schedule and 15 \nrevenues, Incremental Market Efficiency Use revenues, and revenues \ndistributed and allocated under Attachment AU, implemented in accordance \nwith Section 34.1(2) of this Tariff. The rates, including any applicable \nadjustments for Schedules 7, and 8, 14 revenues, andSchedule 15 revenues, \nIncremental Market Efficiency Use revenues, and revenues distributed and \nallocated under Attachment AU, shall be set forth in the RRR File.4 \n \nIn SPP’s filing to expand its Regional Transmission Organization,5 SPP added \nZone 19 West to include the geographic area of the Upper Missouri Zone located in the \nWestern Interconnection. The rate sheet for the Upper Missouri Zone is applicable to \nentities located in the Upper Missouri Zone East (“Zone 19 East”) and the Upper \nMissouri Zone West (“Zone 19 West”). \n \n First, SPP adds a reference to Schedule 14 for the DC Tie Access Charge. The \nDC Tie Access Charge is defined as “[a] charge on a transmission reservation utilizing \na West DC Tie that sinks outside of the Zone where the West DC Tie is located.”6 The \nTransmission Customer is responsible for the DC Tie Access Charge determined in \n \n4  \nProposed Tariff, Attachment T Upper Missouri Zone. \n5  \nSouthwest Power Pool, Inc., Submission of Revisions to Tariff, Bylaws, and \nMembership Agreement to Expand the Regional Transmission Organization into the \nWestern Interconnection (Part 1 of 2), Docket No. ER24-2184-000 and (Part 2 of 2), \nDocket No. ER24-2185-000 (June 4, 2024). \n6  \nTariff, Part I, Section 1 – Definitions D."},{"page":3,"startToken":639,"endToken":960,"text":"The Honorable Debbie-Anne A. Reese \nNovember 10, 2026 \nPage 3 \n \nSchedule 14 of the Tariff. SPP adds this reference to the Upper Missouri Zone rate \nsheet because the DC Tie Access Charge is applicable in this Zone. \n \nSecond, SPP adds a reference to Incremental Market Efficiency Use revenues. \nThe Incremental Market Efficiency Use Charge is “[a] market recovery mechanism to \ncompensate West DC Tie Transmission Owners for the expected loss of life of certain \nWest DC Tie facilities due to increased utilization of the West DC Ties by the \nIntegrated Marketplace.”7 SPP adds this reference to the Upper Missouri Zone rate \nsheet because Incremental Market Efficiency Use revenues are applicable in this Zone. \n \nSPP is not including revisions, as proposed in the November 6 Filing to other \nrate sheets, to remove the references to Attachment AU revenues from this rate sheet \nbecause the Upper Missouri Zone includes utilities in the SPP East Region. \n \nIII. \nADDITIONAL INFORMATION \n \nA. \nInformation Provided Per Commission Regulations8 \n \n1. \nDocuments submitted with this filing: \nIn addition to this Transmittal Letter, Clean and Redlined Tariff \nrevisions under the Sixth Revised Volume No. 1. \n2. \nService: \nSPP has electronically served a copy of this filing on all its \nMembers, Transmission Customers, and Market Participants.
