Integrated System Rate Schedules
The Administrator, Southwestern Power Administration (Southwestern), completed an annual review of the continuing adequacy of the existing hydroelectric power rates for the Integrated System which are in effect through September 30, 2017. This review, included within the 2017 Integrated System Power Repayment Study (PRS), indicated the need for a revenue adjustment of 0.7 percent to continue to satisfy cost recovery criteria. Because the 0.7 percent revenue adjustment is within Southwestern's established 2 percent rate adjustment threshold, the Administrator has deferred the revenue adjustment and is proposing, to the Deputy Secretary for interim approval, a two-year extension of the Integrated System Rate Schedules for the period October 1, 2017 to September 30, 2019. Southwestern's current Integrated System Rate Schedules P-13, NFTS-13A, and EE-13 are set to expire September 30, 2017.
