IPC-03- IDAHO IRRIGATION PUMPERS REBUTTAL TESTIMONY ANTHONY J. YANKEL March 19, 2004 PLEASE STATE YOUR NAME, ADDRESS, AND EMPLOYMENT. I am Anthony J. Yankel. I am President ofYankel and Associates, Inc. My address is 29814 Lake Road, Bay Village, Ohio, 44140. ARE YOU THE SAME ANTHONY Y ANKEL THAT FILED DIRECT TESTIMONY IN THIS CASE? Yes. I am filing rebuttal testimony in order to address oversights or inaccuracies in the testimony that was filed on February 20 2004 by various intervenors and the Commission Staff. PLEASE SUMMARIZE THE TESTIMONY OF OTHER INTERVENORS AS THEY ADDRESSED THE COMPANY'S COST-OF-SERVICE RESULTS AS IT IMPACTED THE IRRIGATORS. None of the other Intervenors have made a significant attempt to analyze or scrutinize the validity of the Company s cost-of-service study. Instead, they blindly accept the results (which help their customer class) and argue that the rate increase should be placed entirely on the back of the Irrigators. Unfortunately, in this case there is a glaring lack of review and validation ofthe Company s cost-of-service study compared with other general rate cases. Yankel, Reb Irrigators PLEASE GIVE AN EXAMPLE OF THIS LACK OF SCRUTINY OF THE COMPANY'S COST-OF-SERVICE MODEL AND ITS INPUTS. Dr. Peseau, on behalf of Micron, points out that (contrary to the Company s claim) Idaho Power never used an "averaged" weighted 12-CP allocator for generation and transmission demand costs where the average was 50% based upon a marginal cost weighting and 50% based upon an unweighted 12-CP method. Dr. Peseau is correct. He goes on to state that: I can only assume that Idaho Power Company made the decision to change allocation methods in this case to understate the severity of the problem with irrigation rates. I fully agree with this statement as well. I made a similar statement in my direct testimony regarding this switch in Company methodolog;. I found a similar desire on the part of the Company to temper results with respect to its transmission allocator by using a 3-CP method, when a review ofthe Company s 2002 IRP (in combination with its espoused methodology) would result in a l-CP method3 . It would appear that the Company is picking and choosing data and methods that fit its desired results. Dr. Peseau s lack of scrutiny is demonstrated by the results he advocated. Based upon his "correction" of the averaging that Idaho Power utilized, Dr. Peseau proposed that the demand allocator for generation for the Irrigators be increased by 19%4 and the I Direct testimony of Peseau at page 23 lines 4- 2 Direct testimony of Yanke 1 at page 27.3 Direct testimony of Yanke 1 at page 30. 1984/0.1670 = 1.188 Yankel, Reb Irrigators allocator for transmission plant be increased by 33%. As most people involved in ratemaking understand, this is a dramatic shift in costs to this class. However, the results of the cost-of-service run that Dr. Peseau made (using Idaho Power s model) showed that these changes had a minimal effect on the results to the Irrigation class, with the desired rate from the Irrigators now being calculated to be 68.74 millslkWh compared to the 62.15 millslkWh calculated by the Company. As it turns out, the Company s cost-of-service study is flawed, but Dr. Peseau and others did not bother to question the results, or any of the input that goes into this model. THE COMMISSION STAFF DID A SENSITIVITY STUDY WITH THE COMPANY'S COST-OF-SERVICE STUDY TO DETERMINE HOW SENSITIVE THE IRRIGATION CLASS WAS TO SOME OF THE ASSUMPTIONS AND/OR DATA USED. PLEASE COMMENT ON THE THREE COST-OF-SERVICE STUDIES THAT STAFF CONDUCTED FOR THIS PURPOSE. The first study conducted by the Staff (Exhibit 120) calculates a required increase for the Irrigation customers of 47.22%. This study merely mimics the Company s cost-of-service study (but based upon an overall revenue increase of only 14%). The Staffs second study (Exhibit 121) calculates a required increase for the Irrigation customers of 44.45%. This study is based upon the assumption of weighting only four months ofthe 12-coincident peaks (July, August, November, and December). I 5 0.2686 / 0.2021 = 1.329 Yankel, Reb Irrigators do not know why the Staff chose these four months, when the Company s 2002 IRP suggests that there are capacity deficits in the four months of June, July, November and December. I assume that if one leaves out the month of August versus the month of June it would make little difference in the overall result, but this lack of sensitivity should not be taken to mean that all is well with the method or underlying assumptions. The Staffs third study (Exhibit 122) is an unweighted 12-CP method and it calculated the required increase for the Irrigators at 29.38% or about 62% of the increase needed ifthe Company s weightings were used. By comparison, my cost-of service study computer run, using the same unweighted assumptions as the Staff, move the increase needed down to 53% of that required by the Company s weighting factors. The difference here is strictly a function of the model used and not the data or assumptions that are inputted into the model. The Company s computer model has some internal inconsistencies and one of the results of those inconsistencies is that it is not as sensitive to change in allocation factors as it should be. Q. DOES THE STAFF'S COST-OF-SERVICE STUDIES INCLUDE ANY OF THE OTHER ADJUSTMENTS YOU MADE IN YOUR DIRECT TESTIMONY? A. No , the Staffs cost-of-service studies do not attempt to normalize Irrigator (or any class demand) to be consistent with sales and revenue levels, nor does it address the fact that Irrigators do not use, for all practical purposes, the Company s underground distribution system. Yankel, Reb Irrigators THE STAFF'S POSITION ON USING WEIGHTING FACTORS SEEMS TO BE SUMMARIZED AS FOLLOWS: "ANY ANALYSIS THAT DOES NOT WEIGHT THE CRITICAL MONTHS MORE HEAVILY THAN SHOULDER MONTHS DOES NOT CORRECTLY REFLECT FORWARD-LOOKING DEMAND RELATED COSTS DO YOU AGREE WITH THIS STATEMENT? No. First, if we are going to reflect "forward-looking demand related costs" then we should be allocating them to classes that are causing those costs. Second it is one thing to weight some months more heavily than others if, in fact, costs are more heavily incurred in some months than in others, but costs in this case are certainly not heavily incurred in five months with absolutely no marginal demand costs incurred in seven other months. A 5-CP method simply does not reflect cost causation on the Idaho Power system. Furthermore, if one looks at the "unweighted" data, it can be seen that December, which is used in the Company s 5-CP method, has a lower demand than January, February, May and September (which are not included). November is included as one ofthe 5-CP', but there is only one month with a lower coincident peak. January February March April May June July August September October November December 6 Hessing Direct Testimony (q2 page 15 lines 6- 989 MW 996 847 636 209 627 742 315 184 769 706 896 Yankel, Reb Irrigators IF ONE WERE GOING TO APPLY ADDITIONAL WEIGHTS TO THESE FIGURES, WHERE SHOULD ONE TURN FOR DATA? If one were to apply weights to these monthly coincident values that are already self-weighting, then these weights should be based upon the costs that Idaho Power actually pays for its last increment of power on the hour of each monthly peak. Idaho Power has provided such data . Figure 9 below is the average8 ofthe highest single price Idaho Power paid for short-term or intermediate-term firm power at the hour of each monthly coincident peak during 2002 and 2003.

Yankel, Reb Irrigators As can be seen from Figure 9, all months but March and April have at the time of the system monthly peak a price of more than $30/MW with the highest cost being in July at under $52/MW. It is also interesting to note that although the Company did not assign any marginal costs to the months of January, February, May, September, and October; the actual marginal costs incurred at the times of these monthly peaks were very similar to the actual marginal cost that was incurred during the August peaks. Furthermore, the Company assigned less weighting to August than November and December in spite of the fact that these months had higher marginal demand costs. WHAT IMPACT WOULD USING WEIGHTING FACTORS BASED UPON ACTUALLY INCURRED MARGINAL COSTS HAVE ON THE RESULTS OF THE COST-OF-SERVICE STUDY THAT YOU RAN? Although I do not believe that there should be any weighting of the coincident peak values, I have produced a cost-of-service study using these actual marginal costs in order to demonstrate how distorted the Company s weighting factors are. I combined these with the normalization of all demand values and the removal of the allocation of underground distribution plant to the Irrigators. The resulting rate of return of 4.80% for the Irrigators compares favorably with the overall system average rate of return of 4.97%. If the Staff insists that weighting factors must be used, then the weighting factors should be based upon actual cost causation, as opposed to a theory that is inconsistently applied and assigns zero costs in over half of the months. Yankel, Reb Irrigators HAVE OTHER WITNESSES ADDRESSED THE APPROPRIATENESS OF USING MARGINAL OR INCREMENTAL COSTS IN THE SETTING OF RATES? Yes. Dr. Power for AARP has extensively advocated considering the marginal or incremental cost of future usage in the rate setting process-both cost-of- service and rate design. He quotes Idaho Power President J. Lamont Keen as stating: Clearly, growth has not paid for itself. The incremental costs of adding, operating, and maintaining generation, transmission and distribution plant are greater than the embedded costs associated with generation, transmission and distribution plant that have been the basis of Company rates over the last ten years. I fully agree with Dr. Power that the embedded cost of serving present and future customers will exceed the embedded costs. As pointed out by the Company, Idaho Power has undergone significant growth over the last 10 years. As further pointed out there have been reductions in load (specifically FMC and FERC Full Requirements customers) that have balanced out this growth. Thus, in spite of the fact that the normalized residential load has grown 17% since the last case and Schedule 9 load has grown 44%, there has been very little change in overall system load. Until recently this scenario only caused large increases in distribution plant with much smaller increases in generation and transmission plant. Now that the surplus created by eliminating most of the FERC and FMC loads has been absorbed, significant increases in generation and transmission plant costs will be required as well. Because incremental growth (past and present) has had an impact since the last rate case, that growth should be reviewed. Yankel, Reb Irrigators HOW HAS THE GROWTH IN THE IDAHO JURISDICTION BEEN DISTRIBUTED SINCE THE LAST CASE? The following graph shows the percentage load growth by class since the last case. Figure Load Growth 1993-2003 1,400 000 200,000 000 000 800,000 :I: 600,000 :i1E 400,000 200,000 200 000 General General Large Power Residential Service Service Service Irrigation (1)(7)(9)(19)(24)DOE/INEL Simplot Micron Total Jan 14%48%24%131%37%27%149% Feb 17%13%52%21%39%16%30%143% Mar 15%16%54%26%69%49%28%158% Apr 17%21%52%30%37%12%28%122% May 20%27%56%26%18%29%130% Jun 22%31%56%32%14%15%111% Jul 34%35%61%31%22%144%11% Aug 31%20%62%24%17%68%27%131%16% Sept 21%14%63%26%27%22%106%15% Oct 13%19%50%23%17%27%28%128% Nav 13%16%46%20%108%25%30%113% Dee 15%46%24%727%35%27%142% Yankel, Reb Irrigators As can be seen from Figure 10, the normalized energy for the Irrigation class has remained virtually unchanged since the last case. The incremental growth and associated costs over the last ten years has been associated with three customer classes and one special contract customer. From the above table, it can be seen that there was a disproportionate amount of this growth that took place during the summer months. WILL THE IRRIGATORS BE A MAJOR CONTRIBUTOR TO GROWTH AND INCREMENTAL COSTS IN THE FUTURE? Under the Company s present forecast the Irrigation class is only expected to grow at a rate of 0.4% per year compared to: Residential Commercial Industrial 2.4% 2.4% Under this forecast, the Irrigation class will contribute far less to incremental costs than all of the other main customer groups. Because Dr. Power believes that "it is important to find ways of signaling to customers the higher incremental cost associated with providing them with the electric service they seek,,, I suggest that Dr. Power put more of a cost burden on those classes that have caused the growth in the last 10 years and are expected to continue to do so. However, Dr. Power seems quite willing to ignore who is causing this growth with its associated costs, and merely suggests that this increased burden be shoved off to 9 Dr. Power s direct testimony page 12 lines 8 and 9. Yankel, Reb Irrigators the Irrigators. He goes so far as to diminish the impact his proposal would have by declaring Q. But in rural areas, where irrigated agriculture is a more dominant part of the local economy, don t lower irrigation costs stimulate the local economy? A. That is unlikely. "Rural" no longer means "agricultural." Most rural residents are not irrigators. Most rural businesses are not irrigated farms. The rural economy is increasingly diverse and non-agricultural. The economic connection between the rural economy and agriculture has increasingly reversed so that the diversity in the non-agricultural local economy, including the urban economies within commuting distance supports farm families rather than the other way around. Farm and ranch families increasingly supplement their household income and stay engaged in agriculture by taking jobs in the non-agricultural sectors of the surrounding economy. In that sense, promoting the non-agricultural economy is crucial to the survival of family farms and ranches. It is only appropriate to accurately define cost-of-service first and then make regulatory judgments second. It appears as if Dr. Power and others have made no attempt to define cost-of-service, but blindly accepted the Company s study because it offers them a short-term benefit. I am not one to make predictions regarding rate impacts, but reading between the lines of Dr. Power s statement, one may sense that the impact of his suggestion could mean a drastic reduction, if not almost complete elimination of the Irrigation class. With a possible 67% increase over 5-years, this is not at all unlikely. WHAT WOULD BE THE IMPACT OF THE ELIMINATION OF THE IRRIGATION CLASS? 10 Dr. Power s direct testimony beginning on page 23 line 23. Yankel, Reb Irrigators I will leave to others the question of what would happen to the farm economy in the Idaho Power service area. However, from a rate perspective, there are a few things that will obviously happen. There will be more electricity available on the Idaho Power system for the other customers. As a matter of fact, there will be (on a normalized basis) about 1 798 000 MWH available or approximately the same amount as FMC made available when it ceased operation. This amount of additional energy is enough to offset the expected growth for the next five years. This would be a benefit to all of the other customer classes because far less additions to generation and transmission plant would be required. It would have very little impact upon the requirement for additional distribution plant. WHAT HAPPENS AFTER FIVE YEARS? Depending on how the Irrigation load would be eliminated, Idaho Power may need one or more rate cases during this timeframe in order to just keep itself revenue neutral. For discussion purposes, I will make a simplifying assumption that there will not be a rate case for five years-the point at which there are no Irrigators and the point where the growth of the other classes just catches up to the load lost from the Irrigation class. I will make an additional simplifying assumption that there will be no increase in any rate base or expenses between now and then. However, it should be remembered that there was a 68% ($351.2 million II ) increase in Idaho jurisdictional distribution plant investment (underground investment almost tripled by adding $100 million of II Exhibit 20 page 6 line 191 in the last case lists the distribution investment in the Idaho jurisdiction at $513 403 825. Yankel, Reb Irrigators investment) over the last ten years, when there was negligible system load growth and no Idaho Irrigation growth. Ifthe projected growth takes place and is offset by a reduction in Irrigation load, this will have very little impact upon the $400 million in distribution plant investment that is expected in the next 6 years 12. In summary, I am assuming that load grows as projected, the Irrigation load goes to zero, and rate base and expenses stay the same. Basically, this amounts to reallocating present costs under the new load scenario. The resulting energy and demand levels13 are detailed in Exhibit 313. The following is a listing of the percentage changes that would be needed to the main energy and demand allocators using the Company s weightings under such a scenario: Energy (EI0)Demand (DI0) Residential 16%40% General Service- 7 26%20% General Service-21% Large Power-11% DOE 47% Simplot 29% Micron 12% WHY WOULD THERE BE SUCH A SIGNIFICANT SHIFT IN DEMAND ALLOCA TORS IF THE GROWTH WAS RELATIVELY THE SAME FOR EACH CUSTOMER GROUP? 12 Direct testimony of Keen at page 17 lines 1- 13 Demand values based upon the same load factor relationship that exists today.14 The negative growth figures reflect the actual experience over the last 10 years where some classes grew in energy usage, but displayed decreases in peak demand. Yankel, Reb Irrigators Although growth in energy may be relatively equivalent, growth in coincident demand has been far more lopsided over the past 10 years. The need for such significant and disproportionate changes to the demand allocators with no increase in ratebase or expenses points up a shortcoming in the overall allocation process. Basically, we are allocating embedded costs in an environment where growth is costing substantially more per unit. At present, the Irrigation class is a major customer group and has a large portion of costs (both historic as well as newer) allocated to it. If there were a reliable method to separately allocate historic and recent costs, the revenue responsibility for the Irrigation class would be a lot less-such a method does not exist. However, as pointed out above, by removing this large class (that helps to absorb these newer costs without causing them) a more exaggerated shift in revenue responsibility is made toward the class or classes that are causing that growth. All this Commission can do is recognize this shortcoming in its deliberations. AFTER REVIEWING ALL OF THE DIRECT TESTIMONY OF STAFF AND INTERVENORS , HAVE YOUR ORIGINAL RECOMMENDATIONS CHANGED? No. The Commission should not give a disproportionate increase in this case, but establish a separate procedure to give various parties time to work out some of the details and data problems with respect to cost-of-service. After those details have been addressed, the Commission could then hold a hearing to address the disputed issues and then adjust rates as appropriate. If a small increase were given as suggested by Staff Yankel, Reb Irrigators this would be an ideal time to make such a review. To indiscriminately give a significant rate increase to the Irrigation class based upon poor data and methodology would not only be unjust and unreasonable, but it could cause disruptions of an irreversible nature.
