November 5, Re: Tariff Advice No Revisions to Schedule 98, Residential and Small Farm Energy Credit

LISA D. NORDSTROM Lead Counsel lnordstrom@idahopower.com November 5, 2013 Attention: Filing Center Public Utility Commission of Oregon 550 Capitol Street NE, Suite 215 P.O. Box 2148 Salem, Oregon 97308-2148 Re: Tariff Advice No. 13-12 Revisions to Schedule 98, Residential and Small Farm Energy Credit ( Idaho Power or Company ) herewith transmits for filing Tariff Advice No. 13-12 containing proposed revisions to the Company s Schedule 98. Idaho Power has included Schedule 98 containing the proposed revisions and respectfully requests the Public Utility Commission of Oregon ( Commission ), approve this advice with an effective date of January 1, 2014. There are three purposes for this filing: (1) Change the Credit Adjustment section of Schedule 98, increasing the Bonneville Power Administration ( BPA ) Residential and Small Farm Energy Credit ( BPA Credit ) from 0.0327 cents per kilowatt-hour ( kwh ) to 0.0491 cents per kwh for Rate Schedules 7, 9, 15, and 24; (2) implement a 1,000 kwh cap on Residential Qualifying Electric Energy and increase the BPA Credit from 0.0327 cents per kwh to 0.0899 cents per kwh for Schedule 1; and (3) make administrative changes to language in the tariff. Idaho Power requests these changes become effective on January 1, 2014, for the period January 1, 2014, through December 31, 2015. Background Under the terms and conditions of the Pacific Northwest Electric Power Planning and Conservation Act ( NW Power Act ), BPA has established a Residential Exchange Program ( REP ) to pass through benefits from the federal Columbia River power system directly to qualifying residential and small farm customers of participating Pacific Northwest utilities. The REP was suspended in 2007 due to a ruling by the United States Ninth Circuit Court of Appeals. In 2011,, BPA, and others ( the Parties ) signed a Residential Exchange Program Settlement Agreement ( Settlement Agreement ) (BPA Contract No. 11PB-12322) whereby Idaho Power would start receiving monthly

Filing Center Public Utility Commission of Oregon November 5, 2013 Page 2 benefits beginning October 1, 2011. The Settlement Agreement settled the Parties rights and obligations for the REP provided for by the NW Power Act and fixed the total amount of benefits to be paid to participating utilities from 2011 through 2028. Although the Settlement Agreement established fixed annual benefits in total for BPA fiscal years 2012 through 2028, these benefits are allocated to the utilities based upon each utility s Average System Cost ( ASC ) in comparison to BPA s Priority Firm Exchange Rate ( PF Exchange Rate ), and upon a two-year average of the utility s historical eligible loads. A utility s ASC and the resulting benefits are determined through an ASC filing and review process administered by BPA and conducted every two years. Idaho Power s benefit levels are subject to change every two years. The benefit levels may change as a result of changes in the Company s ASC as determined by BPA, and changes in levels of eligible residential and small farm load. Thus, a change in the ASC and/or eligible load can change the value of the benefits that flow to residential and small farm customers. Fiscal Year 2012-2013 ASC Filing As a result of the ASC review conducted for BPA s Fiscal Years ( FY ) 2012 and 2013, Idaho Power s Idaho and Oregon residential and small farm customers were eligible to receive $2,023,616 of annual benefits for the two-year period beginning October 1, 2011. On November 30, 2011, Idaho Power filed Tariff Advice No. 11-15 with the Commission, seeking to re-implement Schedule 98 effective January 1, 2012, and to establish the BPA Credit rate, whereby Oregon residential and small farm customers would receive a credit on their power bills for the period January 1, 2012, through December 31, 2013. That tariff advice was approved by the Commission on December 20, 2011. Fiscal Year 2014-2015 ASC Filing On June 4, 2012, Idaho Power filed its Appendix 1 with BPA to begin the FY 2014-2015 ASC Review Process. The Appendix 1 is an Excel spreadsheet model completed by the participating utility and used by BPA to determine a utility s ASC and the resulting benefits for the upcoming two-year exchange period (in this case, 10/1/2013 through 9/30/2015). The ASC Review Process consisted of several rounds of discovery and comments and concluded in July of 2013, when BPA released its final ASC report. Idaho Power s final ASC for the FY 2014-2015 exchange period is $50.22 per megawatt-hour ( MWh ). Because Idaho Power s exchange period ASC exceeds BPA s PF Exchange Rate (currently $49.753 per MWh) by $0.467 per MWh, Idaho Power s Idaho and Oregon residential and small farm customers are eligible to receive $3,001,496 annually for the FY 2014-2015 exchange period, an increase of $977,880 per year from the FY 2012-2013 exchange period.

Filing Center Public Utility Commission of Oregon November 5, 2013 Page 3 Idaho Power will continue to pass through the benefit amount on a cents per kwh basis to all qualifying electric energy delivered to Oregon customers taking service under Schedules 1, 7, 9, 15, and 24. The calculation of the new BPA Credit rate for qualifying customers, based on the new benefit amount determined by the FY 2014-2015 ASC proceeding, can be found on the attached spreadsheet included with this filing. Benefits at the new credit rate will be passed through on a monthly basis for qualifying residential and small farm usage commencing January 1, 2014. However, benefits for qualifying irrigation usage will be accrued monthly and passed through to irrigation customers each December, concurrent with the Company s annual kwh and property tax rebate program. The irrigation benefits distributed each December will correspond to a prior twelve-month period ending on September 30. For example, irrigation benefits distributed in December 2013 are based on usage from October 2012 through September 2013. Monthly benefits for irrigation customers are limited, for any single customer, to their actual metered energy or 222,000 kwh, whichever is less. Administrative Changes to Tariff Language Qualifying Electric Energy section: In response to a request from Oregon Commission Staff, in the Residential subsection, Idaho Power is implementing a 1,000 kwh per month cap on Schedule 1 residential customers. Oregon residential customers taking service under Schedule 1 will only receive the BPA Credit on their eligible metered energy usage up to 1,000 kwh each month. Because of this cap, the BPA Credit rate for Schedule 1 will be different than the rate for customers taking service under Schedules 7, 9, 15, or 24. This calculation can be found in the spreadsheet included with this filing. Idaho Power is also taking this opportunity to eliminate some confusion from the Small Farm section, and to add a section for Irrigation. Small farm customers taking metered service from Idaho Power typically do so under Schedule 7 or Schedule 9 for their general farm operations, while any metered service they use for Irrigation purposes would fall under Schedule 24. The existing tariff reads as though only small farms taking service under Schedule 24 qualify to receive benefits, subject to the 222,000 kwh cap. This is not the case. BPA s Customer Load Eligibility Guidelines state that load qualifies under the REP if it is used for residential purposes, for small farm operations, or for irrigation/pumping load used for agricultural purposes. Idaho Power has been providing benefits to its eligible small farm loads taking service under Schedules 7 and 9. The following link will take you to BPA s Customer Load Eligibility Guidelines: http://www.bpa.gov/finance/residentialexchangeprogram/documents/rep%20cleg_06-26-13.pdf. Therefore, in this filing, Idaho Power would like to clarify the Small Farm subsection by changing the reference from Schedule 24 to Schedule 7 or 9, by removing the reference to the 222,000 kwh cap, and by removing the last sentence that begins Small farm Customers will be identified by tax identification number. Idaho Power proposes to move these items to a new subsection titled Irrigation.

Filing Center Public Utility Commission of Oregon November 5, 2013 Page 4 Credit Adjustment section: In this section, Idaho Power proposes to increase the BPA Credit rate for Schedules 7, 9, 15, and 24 from 0.0327 cents per kwh to 0.0491 cents per kwh. As discussed in the previous section, Idaho Power plans to implement a 1,000 kwh per month cap for Schedule 1 residential customers; as a result of this plan, Idaho Power proposes to increase the BPA Credit rate for Schedule 1 from 0.0327 cents per kwh to 0.0899 cents per kwh. Idaho Power will also change the last two sentences to clarify when the identified customer classes will receive the BPA Credit. respectfully requests that the Commission approve the revised Schedule 98 effective January 1, 2014, which will adjust the BPA Credit rate for Oregon residential and small farm customers for the period January 1, 2014, through December 31, 2015.
