Goins- DOE - RB Page i INTRODUCTION PLEASE STATE YOUR NAME, OCCUPATION, AND BUSINESS ADDRESS. My name is Dennis W. Goins. I operate Potomac Management Group, an economic and management consulting finn. My business address is 5801 Westchester Street Alexandria, Virginia 22310. ARE YOU THE SAME DENNIS W. GOINS WHO PREVIOUSLY FILED DIRECT TESTIMONY IN THIS CASE? Yes. ON WHOSE BEHALF ARE YOU APPEARING? I am appearing on behalf of the US Department of Energy representing the Federal Executive Agencies (PEA), which is comprised of all Federal facilities served by Idaho Power Company (IPC). Two of the larger PEA facilities are the Department of Energy s Idaho National Engineering and Environmental Laboratory (DOE/INEEL) and Mountain Home Air Force Base. IPC serves DOE/INEEL under a special contract and serves the bulk of Mountain Home AFB's load under Schedule 19 Large Power Service. WHAT IS THE PURPOSE OF YOUR REBUTTAL TESTIMONY? The purpose of my rebuttal testimony is to respond to certain statements and/or recommendations in the direct testimony filed by Anthony 1. Yankel on behalf of the Idaho Irrigation Pumpers. In particular, I respond to several of Mr. Yankel's criticisms of the cost-of-service study (COSS) performed by Idaho Power Company (IPC). Case No.IPC-E-O3- Dennis W. Goins-DOE- Page 1 REBUTTAL TO ANTHONY YANKEL DOES MR. YANKEL GENERALLY IMPLY THAT IPC'S COST-OF- SERVICE STUDY IS FATALLY FLAWED? Yes. Mr. Yankel criticizes practically every aspect ofIPC' s cost-of. service study. For example, he states that IPC' .. . cost-of. service model is little better than a "Black Box." (Yankel direct at page 23, lines 13-14) .. . cost-of-service study produces erroneous and unreliable results. (Yankel direct at page 3, lines 4- . .. load research data is also not subject to scrutiny. (Yankel direct at page , line 17) DO YOU AGREE WITH MR. YANKEL'S CRITICISMS? No. I reviewed Mr. Yankel's testimony regarding alleged deficiencies in IPC's cost study. In my opinion, IE did not identify any major flaw in IPC's costing model or methodology that renders them unusable in this proceeding. To the extent that he identified verifiable data errors, IPC should correct these errors and update its cost-of- service results. However, to the extent that Mr. Yankel's criticisms do not reflect errors that can be empirically verified, his recommendations regarding IPC's cost study should be rejected. DOES IPC'S COST-OF-SERVICE STUDY CONTAIN ANY FLAWS? Yes. For example, the ability to examine each computational step in IPC's cost study would be preferable to the Black Box approach that Mr. Yankel criticizes. However Case No.IPC~E-O3- Dennis W. Goins- DOE - RB Page 2 Mr. Yankel's own analysis rebuts his Black Box criticism. Specifically, when he conducted a class cost-of. service study using classification and allocation methodologies found in IPC's jurisdictional COSS, Mr. Yankel found that the results from his Basic model were "very similar" to the results from IPC's study. Reasonableness-not flawlessness-should be the standard by which we judge a cost study. I have never seen a flawless cost study, and I recognize that class cost responsibility cannot be determined with certainty. In my opinion, IPC's cost study reflects a reasonable approximation of class cost responsibility.2 . Under the flawless standard implied in Mr. Yankel's testimony, the Commission should disregard any cost study that cannot determine class cost responsibility with certainty. This standard is unreasonable, not in the public interest, and should be rejected. IS MR. Y ANKEL'S RECOMMENDED SYSTEM AVERAGE INCREASE IN IRRIGATION RATES SUPPORTED BY RESULTS FROM COST STUDIES PRESENTED BY STAFF AND MICRON? No. The Staff and Micron studies reach the same conclusion shown in the IPC study- Irrigation rates are significantly below cost of service and should get an above-average increase. This finding is not a surprise. Cost-of.service results :fTom IPC's previous rate case showed that rates for Irrigation customers were well below cost of service. That trend continues today. Even Mr. Yankel'Basic study indicates that Irrigation rates are well below cost of service. Mr. Yankel recommends a system average increase in Irrigation rates only after rejecting his Basic cost study, making ahost of I Anthony Yankel, direct testimony at page 24, line 15 to page 25, line 2.2 Cost studies presented by Staff and Micron also appear to reflect reasonable efforts to identify IPC's class cost of service.3 Anthony Yankel, direct testimony at page 25, lines 6-, and Exhibit 302, column B. Case No.IPC-E-O3- Dennis W. Goins- DOE - RB Page 3 data and methodological adjustments, and picking a 12CP cost allocation methodology that favors Irrigation customers. DOES MR. Y ANKEL PROVIDE A REASONABLE BASIS FOR CONCLUDING THAT THE AVERAGE ELECTRICITY PRICE PAID BY RESIDENTIAL CUSTOMERS SHOULD BE HIGHER THAN THE AVERAGE PRICE PAID BY IRRIGATION CUSTOMmS? No. Mr. Yankel suggests a 4-point reality check that allegedly demonstrates why the average price per kWh paid by IPC's Irrigation customers should be less than the average price paid by Residential customers. However, at least two parts of his 4-part reality check are not supported by analysis or fact. More specifically, Mr. Yankel contends .that Irrigation customers should pay a lower average price in part because they: Are large users... with lower distribution and customer related costs per kWh." Mr. Yankel has conducted no study or analysis to support this statement. 5 Generally have a much higher load Rctor (ratio of average use to non- coincident use)." Again, Mr. Y ankel has conducted no study or analysis to support this statement.6 Moreover, an analysis of data :fTom IPC's Exhibit 40 indicates that Mr. Yankel is wrong. As shown in Exhibit 404, the test- year load factor (using monthly maximum coincident peak demand) for Residential customers was almost 50 percent, while the load factor for 4 Anthony Yankel, direct testimony at page 18, lines 14-23. 5 IRP A response to IPC data request 1. 6 IRPA response to IPC data request 1.8. Case No.IPC-E-O3- Dennis W. Goins- DOE - RB Page 4 Irrigation customers was only about 26 percent-almost less than half the Residential load factor. WHY WAS THE IRRIGATION TEST-YEAR LOAD FACTOR SO LOW RELATIVE TO THE RESIDENTIAL LOAD FACTOR? Residential customers had relatively balanced loads throughout the year compared to Irrigation customers. (See Exhibit 405.) For example, Irrigation loads in October-April were less than 20 percent of coincident peak loads during May-September. Irrigation customers impose significant demands on IPC's supply resources during months in which the summer peak is almost certain to occur, yet these customers utilize very little of this demand in seven months of the year. As a result, I am not surprised that the average electricity price for Irrigation customers was higher that the average Residential pnce. DOES THE POOR IRRIGATION LOAD PROFILE SUGGEST WHY MR. YANKEL FAVORS THE 12CP METHOD TO ALLOCATE DEMAND- RELATED GENERATION AND TRANSMISSION COSTS? Yes. Under IPC's proposed allocation methodologies (as well as the methodologies proposed by Staff and Micron), Irrigation customers cannot avoid their responsibility for IPC's demand-related generation and transmission costs. In contrast, because Irrigation loads fall dramatically in October-April, Mr. Yankel's recommended 12CP methodology would relieve Irrigation customers of significant share of their responsibility for these costs. DOES THIS COMPLETE YOUR REBUTTAL TESTIMONY? Yes. Case No.IPC-E-O3- Dennis W. Goins - DOE - RB Page 5 STATE OF IDAHO BEFORE THE IDAHO PUBLIC UTILITIES COMMISSION CASE NO.
