IPC-E-08-16 IDAHO POWER COMPANY DIRECT TESTIMONY OF COURTNEY WAITES 1 Q.Please state your name and business address. 2 A.My name is Courtney Waites. My business 3 address is 1221 West Idaho Street, Boise, Idaho. 4 Q.By whom are you employed and in what 5 capacity? 6 A.I am employed by Idaho Power Company as a 7 Pricing Analyst. 8 Q.Please describe your educational background. 9 A.In December of 1998, I received a Bachelor 10 of Arts degree in Accounting from the University of Alaska 11 in Anchorage, Alaska. In 2000, I earned a Master of 12 Business Administration degree from Alaska Pacific 13 University. I have attended New Mexico State University's 14 Center for Public Utilities and the National Association of 15 Regulatory Utility Commissioners Practical Skills for the 16 Changing Electric Industry conference and the Electric 17 Utility Consultants, Inc., Introduction to Rate Design and 18 Cost of Service Concepts and Techniques for Electric 19 Utilities conference. 20 Q.Please describe your business experience 21 with Idaho Power Company. 22 A.I became employed wi th Idaho Power Company 23 in December 2004 in the Accounts Payable Department. In 24 2005, I accepted a Regulatory Accountant position in the WAITES, DI 1 Idaho Power Company 1 Finance Department where one of my tasks was to assist 2 responding to regulatory data requests pertaining to the 3 finance scope of work. In 2006, I accepted my current 4 position, a Pricing Analyst, in the Pricing and Regulatory 5 Services Department. My duties as a Pricing Analyst 6 include providing support for the Company's various 7 regulatory activities including tariff administration, 8 regulatory ratemaking and compliance filings, and the 9 development of various pricing strategies and policies. 10 Q.What is the scope of your testimony in this 11 proceeding? 12 A.My testimony will detail the costs 13 associated with the Advanced Metering Infrastructure 14 ("AMI") deploYment ("Proj ect") . 15 Q.Please describe the costs you will be 16 addressing in your testimony. 17 A.First, I will address the capital costs 18 associated with the three-year deploYment of the AMI 19 Proj ect. Next, I will describe the Company's request to 20 accelerate the depreciation of the existing meters. 21 Finally, I will describe the Company's estimate of the 22 quantifiable Operations and Maintenance ("O&M") savings as 23 a result of the deploYment. WAITES, DI 2 Idaho Power Company 1 Q.What are the total capital costs associated 2 with the Project? 3 A.The total capital costs associated with the 4 Project are $70.9 million,as seen on Exhibi t No.4. 5 Q.Is the Company providing a capital cost 6 "commitment"estimate for the capital costs of the Project? 7 A.Yes,the Company is willing to commit to the 8 Commission that the total cost of the Proj ect to be 9 included in the Company's rate base will not exceed $70.9 10 million ("Commitment Estimate"). This amount includes 11 Information Technology ("IT") expenditures, meter costs, 12 stations equipment expenses, plus additional costs the 13 Company knows it will incur but cannot precisely quantify 14 at this time. These additional costs include, but are not 15 limited to, sales taxes, customer growth, fuel charges, 16 additional IT hardware, software, and personnel time, and 17 the cost of Idaho Power oversight of the Proj ect. The 18 Commitment Estimate also covers contingencies, such as 19 change orders and customer growth. However, the Commitment 20 Estimate is subject to adjustment to account for 21 documented, legally-required equipment changes and material 22 changes in assumed escalation rates or growth rates not 23 foreseen at the time of the Application. WAITES, DI 3 Idaho Power Company 1 Q.Please describe the IT expenditures included 2 in the Commitment Estimate. 3 A.The total IT expenditures associated with 4 the AMI Project and allocated to the Idaho jurisdiction are 5 $1,631,736, as shown on Exhibit No.4. These expenses are 6 related to the hardware and software installations and the 7 testing and interface development of the Meter Data 8 Management System and the TWACS Net Server. These expenses 9 include the costs of servers, licenses, sales tax, and 10 labor with payroll loadings. 11 Q.Are there any costs included in the IT 12 expenditures that the Company has identified as those that 13 cannot be precisely quantified? 14 A.No. Although the IT expenditures include 15 sales tax, the purchase of the products will occur during 16 the year 2008, when the sales tax is known and measurable. 17 Q.Please describe the meter costs included in 18 the Commitment Estimate. 19 A.The meter costs included in the Commitment 20 Estimate associated with the AMI Project and allocated to 21 the Idaho jurisdiction are $54,964,643, as shown on Exhibit 22 No.4. These costs are made up of three components: the 23 meters, the TWACS communications modules, and the meter 24 exchange services. As Mr. Heintzelman describes in his WAITES, DI 4 Idaho Power Company 1 testimony, Landis+Gyr Inc. ("Landis+Gyr") will supply the 2 residential meters and General Electric Company ("GE") will 3 supply the commercial meters. In the contract, Landis+Gyr 4 has committed to a fixed price for five years and GE has 5 committed to a fixed price for three years. 6 The Company has contracted with Aclara Power-Line 7 Systems Inc. ("Aclara") to provide the TWACS communications 8 modules with a five-year fixed price. These modules will 9 be shipped directly to the meter manufacturers, Landis+Gyr 10 and GE, for integration into the meters. The AMI equipped 11 meter will then be shipped directly to Tru-Check, Inc. 12 ("Tru-Check") the meter exchange vendor, which makes up the 13 third component of the meter costs included in the 14 Commitment Estimate. Tru-Check will then install the AMI 15 equipped meters throughout the Company's service territory 16 at a per meter cost based on the area of installation, 17 which is defined in the contract. Together, with stores 18 loadings, sales tax, and overheads, these three components 19 make up the total meter costs of $54,964,643, shown in 20 Exhibit No.4, included in the Commitment Estimate. 21 Q. Are there any costs included in the meter 22 costs that the Company has identified as those that cannot 23 be precisely quantified? WAITES, DI 5 Idaho Power Company 1 A.Yes. The meter costs include a sales tax 2 assumption of six percent over the course of the three-year 3 deploYment. However, the sales tax is subj ect to change 4 and could adjust the total meter costs upwards or 5 downwards. Also, as part of the cost analysis, the Company 6 forecasted customer growth and incorporated the associated 7 meter costs into the Commitment Estimate. During the 8 three-year deploYment, the Company assumes a growth rate 9 which averages 2.7 percent for the residential class, 2.5 10 percent for the commercial class, and 1.5 percent for the 11 irrigation class. In addition, the Company negotiated a 12 fuel escalation clause into the contract with Tru-Check, 13 the meter installation vendor. The per meter installation 14 cost by area included in the contract assumes a fuel cost 15 of $4. OO/gallon of gasoline. However, the fuel clause 16 allows for.a $0.01 per meter adjustment for every $0.10 17 movement in the price of gasoline. That is, if the price 18 per gallon of gasoline goes up $0.10, Tru-Check is entitled 19 an extra $0.01 per meter installed. Likewise, if the price 20 per gallon of gasoline decreases, the Company's cost of 21 installation per meter decreases at the same $0.10/$0.01 22 rate. 23 Q.Please describe the stations equipment 24 expenses included in the Commitment Estimate. WAITES, DI 6 Idaho Power Company 1 A.The total stations equipment expenses 2 associated with the AMI Proj ect and allocated to the Idaho 3 jurisdiction are $14,268,522, as shown on Exhibit No.4. 4 This equipment is necessary for upgrades to the substations 5 for the deploYment of the Proj ect which may include new 6 modulation transformer units, third-party backhaul 7 communications/frame relays, control receiver units, 8 outbound modulation units, inbound pickup units, other 9 miscellaneous materials, and the Idaho Power labor 10 associated with the stations upgrades. All station 11 equipment material cost estimates are fully loaded with 12 stores loading, sales tax, and overheads. The labor 13 included in the estimate is also fully loaded. 14 Q.Are there any costs included in the stations 15 equipment expenses that the Company has identified as those 16 that cannot be precisely quantified? 17 A.Yes. The stations equipment expenses 18 include the same sales tax assumption of six percent over 19 the course of the three-year deploYment as that assumed in 20 the meter costs. Therefore, a change in the sales tax 21 could adjust the total stations equipment expenses upwards 22 or downwards. 23 Q.Are there any other costs associated with 24 the AMI Project that are not included in the Commitment WAITES, DI 7 Idaho Power Company 1 Estimate? 2 A.No. 3 Q.How does the Company propose that the 4 Commission treat the costs associated with the Proj ect for 5 ratemaking purposes? 6 A.Provided the Proj ect costs are less than the 7 Commitment Estimate of $70.9 million, Idaho Power would 8 expect the Commission to ultimately approve the total 9 Proj ect investment to be included in the Company's rate 10 base for ratemaking purposes. 11 Q.Do you have an estimate of the annual 12 revenue requirement to be recovered from customers? 13 A.Yes. The Company has put together an 14 estimate of an annual revenue requirement for the 15 additional plant to be included in rate base for the year 16 2009 only. The total 2009 revenue requirement is $3.82 17 million, which can be seen on Exhibit No.5. 18 Q.In this Application, the Company is 19 requesting to accelerate the depreciation of the old 20 meters. What is the net plant value of the old meters? 21 A.The Company estimates the net plant value of 22 the old meters on December 31, 2008, based on the actual 23 net plant value as of March 31, 2008, and forecasted net 24 plant values through December 31, 2008, will be WAITES, DI 8 Idaho Power Company 1 $27,637,090. As can be seen from Exhibit No.4, for 2 presentation purposes, the Company has assumed a straight 3 line depreciation method for the old meters over three 4 years. 5 Q.Has the Company calculated an estimate of 6 the annual revenue requirement to be recovered from 7 customers for the accelerated depreciation of the old 8 meters? 9 A.Yes. However, in an attempt to mitigate the 10 impact of the increased revenue requirement, the Company 11 felt it was reasonable to also calculate the O&M benefits 12 the Company expects from the deploYment of the AMI Proj ect 13 and offset the revenue requirement of the accelerated 14 depreciation of the old meters by that amount. Although 15 the two items are not related, their impact on the 16 Company's revenue requirement would occur at the same time. 17 Q.What are the O&M benefits associated with 18 the Proj ect? 19 A.The Company expects quantifiable O&M 20 benefits from the following areas: reduction in labor and 21 transportation costs related to meter reading, regional 22 operations benefit in confirming equipment outage to 23 prevent crew dispatch, regional operations benefits in 24 confirming service restored to prevent prolonged crew time WAITES, DI 9 Idaho Power Company 1 in area, regional operations benefit on detecting 2 overloaded distribution transformers, benefit with regards 3 to the operation of the irrigation peak rewards program, 4 and outage management operation benefits. The O&M benefits 5 identified for the three-year deploYment period are shown 6 on Exhibit No.4. 7 Q.What is the estimate of the 2009 revenue 8 requirement associated with the accelerated depreciation of 9 the old meters less the O&M benefits to be recovered from 10 customers? 11 A.When the first year of accelerated 12 depreciation is offset by the O&M benefits anticipated in 13 2009, the estimated 2009 revenue requirement is $8.40 14 million, as shown on Exhibit No.6. 15 Q.Has the Company included the costs 16 associated with the accelerated depreciation of the old 17 meters less the O&M benefits as part of the Commitment 18 Estimate? 19 A.No. The accelerated depreciation less the 20 O&M benefits is not a component of the Commitment Estimate. 21 The Commitment Estimate is for capital costs. 22 Q.Does this conclude your testimony? 23 A.Yes, it does.
