Vandiver, First Assistant City Attorney DGV:da/AGENDA-D1/SPS.res rev. October 19, 1993 Lei SOUTHWESTERN PUBLIC SERVICE COMPANY October 4, 1993 The Honorable Mayor David Langston and Members of the City Council City of Lubbock Lubbock, TX Dear Mayor Langston and Members of the City Council: Attached is Southwestern Public Service Company's application request- ing approval to implement lower rates on an interim basis inside the city. After many months of work, SPS has reached a stipulated agreement with the Public Utility Commission (PUCT) Staff, the cities Steering Comm- ittee and all other intervenors in the Rate Review case that was intiat- ed by the PUCT last October. The settlement agreement is for a rate reduction of approximately $13 million, or about 2.9%, when applied to SPS's state-wide retail rates in Texas. SPS's retail electric rates already are the lowest of all investor -owned utilities in Texas. With your approval, they will become even lower and further increase the attractiveness of our community for economic development and jobs. The agreement calls for the rate reduction to become effective for service on and after October 15, 1993. The rate reduction for our town will be implemented under the same Interim Rates, which have been approved for rural areas by the Administrative Law Judge at the PUCT. Those Interim Rates will become final rates when the Comm- issioners of the PUCT formally issue a final order in the case under the terms of the agreement. All: The city must approve any rate change under its authority as the primary jurisdiction rate regulator of SPS. Your approval is nec- essary to implement the Interim Rate Reduction inside the city. After the PUCT issues its final order in the case accepting the stip- ulation, we will file a supplemental application requesting your approval to make these rates final. The Unanimous Joint Stipulation is included as Attachment A to SPS's application, and the proposed new tariffs are included as Attachment B. We respectfully request your approval of this rate reduction as soon as possible. Please let me know if you need additional information or any other assistance from us. As always, we will be pleased to work with you. ��� Since ocr 1993 �o J e Webb, Manager N Lubbock District U:DCITY S �R TA Y APPLICATION OF SOUTHWESTERN PUBLIC SERVICE COMPANY POk CITY OF RATE CHANGE ) APPLICATION FOR INTERIM RATE CHANGE AND STATEMENT OF INTENT TO CHANGE RATES Southwestern Public Service Company ("Southwestern") files this Application for Interim Rates and Statement of Intent to Change Rates with the City and would show as follows: Southwestern is currently in a rate case at the Public Utility Commission of Texas, Docket No. 11520, which has been resolved by a Unanimous Joint Stipulation with all parties, including representatives of certain cities in Southwestern's Texas service territory.

Qualifying Facility VOM as used in this tariff, means a cogeneration or small power production facility which qualifies under Title 18, Chapter 1, Subchapter K, Part 292, Subpart B of the Code of Federal Regulations (Federal Energy Regulatory Commission's regulations implementing Sections 201 and 210 of the Public Utility Regulatory Policies Act of 1978 with regard to small power production and cogeneration). Nothing in this tariff shall limit the authority of the Company and the Customer to negotiate and agree to a rate for any purchase, or terms or conditions relating to any purchase, which differ from the provisions of this tariff. PAYMENT DETERMINATION Company will pay the customer for non -firm energy received from the OF at a rate equal to Company's hourly Adjusted Non -firm Energy Cost (ANFECi) times the kilowatt-hours delivered by the OF each respective hour during the month times the specific predetermined loss factor appropriate to Customer's OF. Monthly Payment = Sum of hourly payments during the month minus the monthly administrative charge Hourly Paymenti ANFECi x kWhQF J x LFQF where: ANFECi Adjusted Non -firm Energy Cost for hour i as expressed in dollars per kilowatt-hour and rounded to six decimal places; Effective Date October 15, 1993 TXTAR 117-1 Approved Page 2 of 4 kWhOFJ = kilowatt-hours delivered by Customer's OF during hour i of the month; LFQF = predetermined Customer specific loss factor; OF refers to Customer's specific qualifying facility; and i refers to a specific hour within the month. PURCHASE OF NON -FIRM ENERGY FROM QUALIFYING FACILITIES ANFECi represents the Company's adjusted average avoided energy cost for hour i as computed in accordance with the PUCT regulations W.U.C. SUBST. R. 23.66(g)). The ANFECi factor for each hour i of the month will be calculated as ninety-nine percent (99%) of Company's average Non -Firm Energy Cost ("NFECi") for each respective hour. The formula for ANFECi is as follows: ANFECi = 99 percent x NFECi where: NFECi = non -firm energy cost factor for hour i of the month as expressed in dollars per kilowatt-hour; NFECi represents the Company's computed average non -firm avoided energy cost for each hour i of the month. NFECi will be determined by Company as the difference in Company's production costs with and without the total amount of non -firm energy provided by all OFs pursuant to this tariff divided by the total amount of non -firm energy provided by all QFs pursuant to this tariff. The formula for NFECi is as follows: CPC - CPC NFECi = 1.i O.i TNFEi where: CPC1,i = Company's reconstructed production costs, including purchased power expenses, for hour i as if all non -firm energy supplied by QFs pursuant to this tariff was generated by Company or purchased from another source; CPCO j = Company's actual production costs, including purchased power expenses (exclusive of purchased power costs for purchases made from QFs pursuant to this tariff), for hour i with all Customer's non - firm energy avoiding Company's production costs or other purchased power expenses; and TNFEi total non -firm energy provided during hour i by all QFs supplying energy to Company pursuant to this tariff. N Page 3 of 4 Company's System Planning Department will calculate a predetermined loss factor ("LFQF") applicable to Customer's specific OF to account for the increase or decrease in transmission system losses attributable to the presence of the Customer's OF on Company's electrical system. The loss factor will be determined usingpower flow analysis to calculate the annual average incremental or decremental losses in the Company's system resulting from the purchase of non -firm energy from Customer's OF. PURCHASE OF NON -FIRM ENERGY FROM QUALIFYING FACILITIES if Customer requests in writing, and within six months of any payment period, Company shall make available supporting information from which the monthly calculations for payment were made. The payments for non -firm energy will be made to Customer provided the PUCT recognizes such payments as allowable purchased energy costs to be fully recoverable under the PUCT's regulations (PUC SUBST. R. 23.23). Company will assess in accordance with the PUCT's regulations (P.U.C. SUBST. R. 23.66(g)(2)(E)) a monthly administrative charge to compensate for the computation and billing the hourly ANFECs and the Customer's credit statement. This charge will be subtracted from Customer's monthly credit statement regardless of whether Company has purchased non -firm energy from the Customer's OF during such billing period. In the event the PUCT enters an order authorizing Company to make any change in the above administrative costs which Company receives from the Customer, such change shall be automatically implemented as a part of this tariff. PAYMENT Company shall read Customer's OF meter monthly, send a statement and make a payment on or before the 20th calendar day after the meter is read; except that Customer will make arrangements with Company to ensure that all payments to Company for electrical service will be made and are current on or before the day of Company's payments to Customer. The statement will show the summation of the hourly kilowatt-hours of energy metered and delivered by the Customer's OF, the monthly average hourly ANFEC factor, the monthly administrative cost assessment by Company, and the total credit amount to Customer or the amount due to Company. CONTRACT The sale of non -firm energy to the Company by Customer under this tariff requires a written contract. The contract shall be negotiable by the Company and the Customer. INTERCONNECTION COSTS If the Company determines an interconnection study is necessary, the Company shall perform such study within a reasonable period of time under reasonable terms and conditions agreed upon by the parties. The Customer shall be responsible for the costs of such study. The interconnection study shall determine the equipment and facilities, and the costs associated therewith, that must be designed, purchased, installed, modified, replaced, and/or removed to economically, reliably, and safely integrate Customer's OF into the Company's electrical system. Page 4of4 PURCHASE OF NON -FIRM ENERGY FROM QUALIFYING FACILITIES The Customer shall pay any interconnection costs, which are defined as the costs ` of connection, switching, metering, telemetering, transmission, distribution, safety provisions, or any other costs directly related to the installation of physical facilities necessary to permit interconnected operations with the Customer, to the extent such costs are in excess of the corresponding costs that the Company would have incurred if it had not engaged in interconnection 'operations,, but. instead generated an equivalent amount of electric energy itself or purchased an equivalent amount of electric energy from other sources. Interconnection costs do not include any costs included in the calculation of avoided costs.
