Dear Secretary Bose:

Pursuant to section 205 of the Federal Power Act, 16 U.S.C. § 824d, and section 35.13 of the Federal Energy Regulatory Commission’s (“Commission”) regulations, 18 C.F.R. § 35.13, Southwest Power Pool, Inc. (“SPP”) submits: (1) an executed Service Agreement for Network Integration Transmission Service (“Service Agreement”) between SPP as Transmission Provider and Western Area Power Administration - UGP (“WAPA”) as Network Customer (“Sixth Revised WAPA Service Agreement”); and (2) an executed Network Operating Agreement (“NOA”) among SPP as Transmission Provider, WAPA as Network Customer and Basin Electric Power Cooperative (“Basin”), Central Power Electric Cooperative, Inc. (“Central Power”), Corn Belt Power Cooperative (“Corn Belt”), East River Electric Power Cooperative, Inc. (“East River”), Missouri River Energy Services (“MRES”), Northwest Iowa Power Cooperative (“NIPCO”), NorthWestern Corporation (“NorthWestern”) and WAPA as Host Transmission Owners (“Sixth Revised WAPA NOA”).1 The Sixth Revised WAPA Agreements modify and supersede the Service Agreement and NOA among the Parties accepted by the Commission in Docket No. ER20-896-000.2 SPP is submitting this filing because

The Honorable Kimberly D. Bose June 8, 2021 Page 2

the Sixth Revised WAPA Agreements include terms and conditions that do not conform to the standard form of service agreements set forth in the SPP Open Access Transmission Tariff (“SPP Tariff”).3

I. Description of the Sixth Revised WAPA Agreements

Since the March Order, the Parties revised the Fifth Revised WAPA Service Agreement in Section 3.0 of Attachment 1 to make a name correction, and revised Appendix 3 to update the delivery points as a result of the Delivery Point Addition study 2021-February-1284. In addition, the Fifth Revised WAPA Service Agreement was updated to include changes to the pro forma Service Agreement approved by the Commission in Docket Nos. ER20-1687,4 ER20-26995 and ER20- 418.6 These changes conform to the pro forma Service Agreement. To facilitate these changes, the Parties executed the Sixth Revised WAPA Service Agreement, which is submitted herein with the Sixth Revised WAPA NOA.

II. Non-Conforming Terms and Conditions

The Sixth Revised WAPA Service Agreement retains the non-conforming terms and conditions without modification in Section 7.0; and Sections 8.5, 8.10, and 11.0 of Attachment 1 from the Fifth Revised WAPA Service Agreement.7 These non-conforming terms and conditions were accepted by the Commission in
