AVISTA CORPORATION RESPONSE TO REQUEST FOR INFORMATION JURISDICTION: CASE NO: REQUESTER: TYPE: REQUEST NO.: IDAHO A VU-E-08-0l / A VU-G-08-0l IPUC Production Request Staff-l03 DATE PREPARD: WITSS: RESPONDER: DEPARTMENT: TELEPHONE: 06/16/2008 Liz Andrews / Tara Knox Tara Knox State & Federal Regulation (509) 495-4325 REQUEST: What would be the proposed rate increase if the proposed revenue requirement had been spread among 2009 loads with associated revenues and the production/transmission asset adjustment eliminated? RESPONSE: If 2009 loads were used to determine the proposed rates, not only would production and transmission costs increase through the elimination of the production property adjustment, but additional pro forma distribution and other costs would be included in the pro fonna results of operations offsetting incremental base rate revenue from the additional customers and load which theoretically results in the same rate increase. The attached Excel worksheet (Staff PR l03-Attachment A.xls) contains an ilustrative example of results of operations adjustments to capture additional costs necessary to have a matching with 2009 loads and customers resulting in the same overall rate increase. The following assumptions were used in this ilustration: l)Debt synchronization and revenue related expenses are computed using the same factors as presented in Andrews Exhibit No. 13, Schedule 1. Incremental general business revenue is computed by multiplying the increase in loads between 2009 and 2007 by the 2007 normalized average base rate revenue per kWh; Incremental distribution operation and maintenance expenses, customer accounting, customer service and information, sales, and administrative and general operating expenses have all been escalated 1 % from the 2007 pro forma values filed in the case to reflect a conservative representation of expected inflation impacting non-labor costs; Incremental distribution depreciation expense is computed at the composite rate for the distribution functional group used in PF6 and PF7; Incremental accumulated depreciation is computed at l.5 times the incremental distribution depreciation expense to approximate 1 and Yi years; Incremental accumulated deferred federal income tax is computed using the weighted average relationship of ADFIT to plant additions in PF6 and PF7; Incremental distribution plant in service is the value required, given the previous computational relationships which results in the same percentage rate increase as requested in the case. 2) 3) 4) 5) 6) 7) Page 1 of2 . . . This ilustration shows how the proposed rate increase could remain l6.73% of general business revenues or an average of 0.9428Ø per kWh spread among 2009 loads. ifthe Company had filed a fully forecasted test year, many assumptions would have been included regarding the 2009 customers. Estimated 2009 revenue at present rates computed from biling detenninants assumed for the 2009 budget result in lower incremental revenue than the amount shown in the ilustration (see response to Staff Production Request No. lOS). Additionally, the New Revenue capital additions excluded from Pro Forma Capital Additions adjustments PF6 and PF7 were greater than the amount shown in the ilustration. Also, the inflation assumption in the ilustration is very conservative and in a fully forecasted test year would also have been applied to non-resource production and transmission operating and maintenance costs. All of these factors lead to the conclusion that if the Company had fied a fully forecasted test year spread over the future test year biling detenninants, the proposed rate increase would have been higher.

A VISTA CORPORATION RESPONSE TO REQUEST FOR INFORMATION JUSDICTION: CASE NO: REQUESTER: TYPE: REQUEST NO.: IDAHO A VU-E-08-0l 1 A VU-G-08-0l IPUC Production Request Staff-l04 DATE PREPARD: WITNSS: RESPONDER: DEP ARTMENT: TELEPHONE: 06/16/2008 Liz Andrews 1 Tara Knox Tara Knox State & Federal Regulation (509) 495-4325 REQUEST: What was the incremental revenue requirement of adjusting the 2007 test year for production/transmission rate base, expense and revenues through 2009? RESPONSE: The Company did not include any revenue requirement from production/transmission rate base, expense or revenues through 2009. The Company did model power supply expenses (including sales for resale revenues) to reflect normalized values with 2009 loads as well as generation and transmission capacity consistent with capital investments expected to be complete by the end of 2008. Production and transmission rate base was adjusted to reflect the investments modeled by power supply. Additionally, known and measurable contract changes expected through 2009 were included in the power supply and transmission pro forma adjustments. However, all production/ transmission rate base, expense and revenues were reduced in the production property adjustment for the impact of expected 2009 loads versus 2007 normalized loads which effectively eliminàtes any incremental revenue requirement from the aforementioned items. The production property adjustment reduced revenue requirement by $7,8l9,000 in this case. At the requested rates expected 2009 loads (compared to 2007 normalized loads) wil contrbute $7,8l9,000 incremental retail revenue for production and transmissions costs. The purpose of utilizing 2009 loads in the power supply modeling is to provide a better matching of expected costs of providing electricity during the time when rates wil be in effect. This allows the authorized base power costs in the Power Cost Adjustment to be aligned with expected current loads instead of loads that are two years outdated. If the Company had reflected all costs through 2009, as discussed in the response to Staff Production Request No. l03, the expected rate increase would have been greater. . . .

RESPONSE: 2009 budgeted biling determinants for Idaho priced at present base rates results in 2009 pro forma retail rate revenue of $20l,l43,496 compared to 2007 pro forma rate revenue of $l93,270,238 which implies incremental retail rate revenue of$7,873,258. As explained in the response to Staff Production Request No. l03, a proper matching of2009 costs with 2009 revenues would result in an increase to the Company's proposed revenue requirement. . . .

In other words, how might each of the costs listed above be changed by serving a customer with both electricity and natual gas? RESPONSE: The Company does not keep records intended to specifically identify these economies. Any economies that do exist are proportionately shared between the electric and gas system by the use of the number of customers allocation factor for common customer-related costs in FERC Accounts 90l through 916 and the four-factor allocation factor for other common costs. Since there are separate meters and services for electric and gas service (even if it occurs atthe same premise) no economies occur for those costs. Likewise, a customer is twice as likely to need call center services if they have both electric and gas services so no paricular economies occur for the bulk of Account 903. Further, with the advent of advanced meter reading, no single premise related economies occur for Account 902 as a trp to the premises is no longer required. . . .
