Integrated System Power Rates
The Administrator, Southwestern Power Administration (Southwestern), has determined that an additional Section outlining a new methodology within Southwestern's existing Integrated System Non- Federal Transmission Service (NFTS-13) Rate Schedule is necessary to better align Southwestern's rate schedule with standard practices utilized by the Southwest Power Pool, Inc. (SPP) Regional Transmission Organization. A new section 2.3.6 is proposed that establishes a procedure for determining an Annual Revenue Requirement (ARR) for customers that choose to contract for Network Integration Transmission Service (NITS) on Southwestern's transmission system pursuant to the SPP Open Access Transmission Tariff (OATT). The proposed Section 2.3.6 does not change Southwestern's NFTS ARR, as determined in its 2013 Integrated System Power Repayment Studies (2013 PRS), but rather replaces the current stated-rate for SPP NITS with a revenue-requirement based methodology that includes determining the SPP NITS ARR portion of Southwestern's NFTS ARR. Furthermore, the proposed Section 2.3.6 affects only those customers that choose to contract for SPP NITS on Southwestern's transmission system under the SPP OATT. Southwestern has determined that Section 2.3.6 will provide a more appropriate methodology for revenue recovery from NFTS customers that choose to contract for SPP NITS on Southwestern's transmission system under the SPP OATT.
