IPC-E-10-24 ) ) IDAHO POWER COMPANY'S ) RESPONSE TO THE FIRST ) PRODUCTION REQUEST OF ) THE COMMISSION STAFF TO ) IDAHO POWER COMPANY ) COMES NOW, Idaho Power Company ("Idaho Powet' or "Company"), and in response to the First Production of Request of the Commission Staff to Idaho Power Company dated September 30,2010, herewith submits the following information: IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 1 REQUEST NO.1: Please provide a copy of the following interconnection and transmission documents when available: a. Feasibilty study b. Facilty Study c. Generation Interconnection Agreement d. Transmission Service Request and the corresponding response from Idaho Powets Transmission group that transmission capacity is available. RESPONSE TO REQUEST NO.1: a. Feasibilitv Study. At Rockland's request, no Feasibilty study was performed. The project requested to go directly to a System Impact Study, which is included on the enclosed CD as Attachment 1A b. Facilty Study. Please see Attachment 18 included on the enclosed CD. c. Generation Interconnection Agreement ("GIA"). The GIA is currently in the final stages of being executed by the parties. Once executed, a copy of the GIA wil be provided in a supplemental response to Staff's Production Request NO.1. d. Transmission Service Request. Because this PURPA project must serve Idaho Powets system native load, it must be a Designated Network Resource ("DNR") on the system. To be a DNR, the Firm Energy Sales Agreement (power purchase agreement) and the GIA must be completed and executed. For PURPA projects, Idaho Power-Power Supply submits the Transmission Service Request ("TSR") and the DNR. The March 18, 2010, letter included on the enclosed CD as Attachment 1D indicates acceptance of the TSR by Idaho Power-Delivery (TSR has been put in study and wil be IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 2 acted upon), conditioned upon receipt of the network resource designation (DNR) from Idaho Power-Power Supply (wil be acted upon once a DNR is received). The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 3 REQUEST NO.2: Please provide a copy of the Aurora project and output files supporting the levelized Aurora energy price result of $56.21 per MWh as referred to on page 6 of the Application. Please provide computations showing how the price of $56.21 was computed using the Aurora results. RESPONSE TO REQUEST NO.2: Please see the following attachments on the enclosed CD: 1. Attachment 2A, which describes the methodology used to execute the AURORA runs for the Rockland project; 2. Attachments 281 and 282 for the requested AURORA output files; and 3. Attachment 2C for the requested computations. The response to this Request was prepared by Rich Pagoago Jr., Planning Analyst, Idaho Power Company, and Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 4 REQUEST NO.3: The Application states that the 25-year levelized price in the Agreement calculates to be $71.29 per MWh. Please explain in detail how the Company got from a 25-year levelized Aurora price of $56.21 per MWh to a negotiated 25-year levelized rate of $71.29 per MWh. Please identify and quantify each additional benefit that Idaho Power believes is not captured in the Aurora price. RESPONSE TO REQUEST NO.3: The avoided cost methodology for qualifying facilty ("QF") projects 1 0 aMW and larger is an Integrated Resource Plan ("IRP") based methodology requiring the utilty to make two runs of its power supply model, one using assumptions consistent with its most recent IRP, and a second with the proposed QF included as a no-cost resource. The difference in net power supply cost computed by the model over the term of the proposed contract represents the value of the QF to the utilty and is supposed to serve as the basis for establishing an avoided cost rate for the proposed QF. The methodology is intended to capture and fairly value the different individual generation characteristics of proposed projects. The IRP-based methodology was set forth in a settlement Stipulation approved by the Commission in Order No. 26576 issued September 1996 in Case No. IPC-E-95-9. Order No. 29487, Case No. IPC-E-04-5. Please see Attachment 2A on the enclosed CD for the AURORA methodology utilzed for the Rockland project. As indicated above, the I RP-based, AURORA methodology establishes the avoided cost basis for the negotiated rate for the particular QF project that is larger than 10 aMW. Because the AURORA-generated avoided cost rate simply represents a market price alternative, the Company recognizes that a PURPA agreement may IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 5 provide additional benefis over a market purchase, and that value should be reflected in a negotiated rate. As stated in the Application for this case, although the $71.29 levelized energy price within this Agreement is greater than the base AURORA value of $56.21, it is also lower than the Published Avoided Cost rate of $75.88. This Agreement provides many additional items of value to Idaho Power and its customers in comparison to a standard PURPA agreement for QFs 10 MW and under. Some of those items being REC ownership, greater security and damage provisions, wind forecasting data, additional contract years at comparatively lower cost, and the right of first offer for ownership or expansion of this site. In addition, the $71.29 price is considerably lower than prices bid into the 2012 Wind RFP issued in May 2009, which Idaho Power recently concluded without awarding a contract. Rockland made this unsolicited proposal of a large 80 MW PURPA project to Idaho Power and requested Idaho Power negotiate this Agreement as required by the applicable PURPA rules and regulations. Historically, many developers have avoided or attempted to avoid this large PURPA contracting process by dividing a large project into multiple, less than 10 average MW projects, thus invoking application of the Published Avoided Cost Rate and the more prescriptive contracting process applicable to those smaller QF projects. Idaho Power believes that the negotiations with Rockland, which resulted in the present Agreement, evidence the fact that the large PURPA negotiation process is viable and can result in a project that is both feasible for the developer and more favorable to Idaho Power customers as compared to Firm Energy Sales Agreements ("FESA") for 1 0 average MW or smaller QF projects. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 6 Consequently, many of the benefits that Idaho Power believes are not captured in the AURORA price modeling correspond to those items identified in the Application as adding additional value above and beyond the typical PURPA FESA that is approved by the Commission for PURPA projects less than 10 aMW. Many, if not all, of these additional items of value are difficult, if not impossible, to quantify precisely. Nevertheless, they do add value that is not sufficiently captured in the pure mathematical calculation done by the AURORA modeling when determining the 25-year levelized AURORA price. A summary of those beneficial items of value follows. These items are more fully summarized in the Application. . Renewable Energy Certificate ownership . Mechanical Availabilty Guarantee . Wind forecasting data · Greater security and damage provisions · Right of first offer for ownership or expansion of the site · Extended term at reduced cost Further, there is additional value in a long-term fixed priced contract as compared to volatile market prices over the same period. Again, the removal of market price risk is difficult to quantify. However, it does some value which should be reflected in the contract price. The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 7 REQUEST NO.4: The Agreement provides that all Renewable Energy Credits (RECs) wil be provided to Idaho Power after year 2021. Has Idaho Power attempted to quantify the value of these RECs? If so, please state the estimated value and show how it was derived. RESPONSE TO REQUEST NO.4: As stated in the Company's Response to Staffs Production Request NO.3, many, if not all, of the additional items of value - including RECs - are diffcult, if not impossible, to quantify precisely. However, Idaho Power used available information about REC pricing to gauge the range of REC pricing from a low of approximately $4.00-$5.00 to a high of $50.00. The Idaho Power 2009 IRP estimated forward REC prices to be approximately $20 in the expected case, and $50 in the high case. Currently, REC prices for WECC wind short- term current transactions are being quoted in the $5.00-$6.00 range. Idaho Power is currently engaged in a hydro REC sale to another utility with a price of $17.50. Califomia Energy Commission certified RECs are currently trading at approximately $15. Here, the project retains the rights to all RECs through the end of calendar year 2021. Idaho Power wil own the rights to all RECs from the beginning of calendar year 2022 through the remaining term of the Agreement (a minimum of 15 years). This allows the QF developer to retain the RECs for the initial ten years of the Agreement and obtain what value it can for them to help offset the cost of development for the project at a time when the Company does not have a Renewable Portolio Standard ("RPS") obligation for the RECs. At the same time, it also allows the Company to retain the RECs for the last 15 years of the Agreement, after the project is developed and mature, and when a future RPS may require the Company to obtain and have RECs. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 8 The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 9 REQUEST NO.5: The contract term specified in the Agreement is 25 years. Does Idaho Power have any evidence that the project wil be able to perform for the full 25 years? Can Idaho Power cite other contracts in the U.S. with a term of 25 years for projects utilzing similar wind turbines as are proposed to be used for the Rockland project? RESPONSE TO REQUEST NO.5: Idaho Power has no firsthand experience with a 25-year wind farm or evidence in regards to the expected life of the wind turbines to be used at this site. The Facilty has made arrangements to use the Vestas V100 wind turbine. Vestas is one of the oldest manufacturers of wind turbines and supplies them worldwide. Vestas wind turbines are in use at the Elkhorn Wind Farm and numerous other wind farms here in the Northwest. Performance requirements within this Agreement provide financial motivation for the project to maintain, operate, and replace the wind turbines as required to meet the Mechanical Availabilty Guarantee for the full 25-year contract term. In addition, Robert Zdebski, Vice President of Development, Construction, and Procurement for Ridgeline has provided the following information: We're confident we can achieve and exceed the 25 year life of the PPA based on: 1) Proven and reliable design. The V100 is based on the proven design of the V80 and V90 1 .8. These are mature platforms using conventional technology and have long track records of operating worldwide in a wide range of conditions. 2) Large, stable manufacturer to provide support and spares. With a large installed base of V80's and V90's we can be confident that support and spares wil continue into the future. Wide use of these machines also ensures a strong aftermarket of IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 10 services including engineering support, service providers and replacement parts manufacturers. 3) Turbine has been selected on a conservative basis with the site operating conditions significantly below normal turbine operating limits. Operating at lower load levels greatly reduces the forces experienced by the unit and increases the operating life. The turbine selected has a nominal wind speed limit of 7.5m/s and a turbulence limit of 0.18% while the actual operating conditions are (O.Om/s and 0.10%). 4) This site is not subject to extreme weather events which also increases turbine life and reduces maintenance issues. 5) Project is being designed with all manufacturers' recommendations for installation and turbine spacing which reduces wake induced loads. 6) Project wil interconnect at a strong and reliable point of the grid. This reduces transient and other electrical disturbances which can negatively impact turbine performance and component life. 7) Robust maintenance program. The turbine manufacturer is providing site-based maintenance and operation services under a 10-year agreement ensuring that all maintenance and operations are carried out per the manufacturets recommendations and requirements. 8) A project operating plan is being developed for planned replacement and overhaul of critical components which wil extend the useful life of the turbine and ensure safe and reliable operation. 9) Vestas wind turbines that were installed 25 to 30 years ago in California are stil operating today (for example at the Vicory Garden and Sky River sites in Tehachapi). Mr. Zdebski leads turbine procurement, late-stage development, construction, and operations for Ridgeline. He was previously vice president of business IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 11 development at Vestas Americas, the world's leading supplier of wind power solutions, where he was responsible for managing the company's business development activities. Mr. Zdebski started his energy career as a field engineer with Dresser-Rand and has commissioned and worked on steam, gas, geothermal, and hydro plants all over the world. His career at Dresser-Rand included leading the application engineering group for the Electric Machinery division focusing on large motors and generators. Robert holds a Bachelor of Science in Aeronautics from St. Louis University. Mr. Zdebski's contact information is as follows: (503) 830-4086 and rzdtãr1- en.com. The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 12 REQUEST NO.6: Many of the terms of the Agreement are different than in standard PURPA contracts for projects smaller than 10 aMW (partial completion damages, simplified MAG, IPCo ownership of RECs, increased security, more forecasting). How do these unique terms and conditions compare to the terms and conditions that were being negotiated with a different project in the Company's 2012 Wind RFP wherein no contract was awarded? RESPONSE TO REQUEST NO.6: Both Idaho Power and the party selected to negotiate a potential wind purchase power agreement through the request for proposal ("RFP") process consider the specific negotiation details and their discussions to be confidential information. A summary of the general RFP bid responses is contained in the Company's Response to Staffs Production Request NO.9. As can be seen in the provided summary, the lowest energy pricing received in the RFP bid process was an approximate levelized energy price of $85, whereas the levelized energy price in this Agreement is $71.29. In comparing the terms and conditions of this Agreement against the routine PURPA agreement, numerous items are clearly more favorable, some of those being: . Energy price · Security Requirements . REC Ownership . Wind forecasting requirements · Performance Guarantee (MAG) The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY -13 REQUEST NO.7: Please explain the rationale for the Signing Security ($300,000) and Operational Security ($1,500,000) required under the Agreement. What damages is each type of security intended to recompense? RESPONSE TO REQUEST NO.7: With regard to the Signing Security of $300,000, Rockland is working with another party to secure a REC sale for the first ten years of this Agreement. Throughout the negotiations of this Agreement, Rockland has expressed that without the REC sales agreement with the third part, Rockland could not justify the pricing included in this Agreement. Rockland has been working on that REC sales agreement simultaneously during the negotiations of this Agreement with Idaho Power and has advised Idaho Power that the REC sales agreement was moving forward as expected. However, Rockland has advised that they could not execute the final REC sales agreement until such time as this Agreement was completed due to the risk that if this Agreement was not completed and approved by the Commission, Rockland could be subject to supply RECs from a project that was not built. As this may be a viable concern by Rockland, Idaho Power and Rockland also agreed that the project could not simply have a "free" out if this occurred since Idaho Power has no control of this REC sale process and termination of this Agreement at this time would cause Idaho Power to incur various revised resource planning costs. The $300,000 security and the associated $300,000 damages was a negotiated value. With regard to the Operational Security of $1,500,000, throughout the term of this Agreement, the Agreement provides for the calculation of damages due Idaho Power if the project fails to meet various performance and other contract requirements. Past history on PURPA agreements has indicated that as damages can contractually be IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 14 calculated and accessed, quite often recovery of those calculated damages can be very difficult as the projects quite often do not have liquid assets available. Security of $1,500,000 was a negotiated value for this Operational Security and provides a certainty that Idaho Power can collect calculated damages, at least up to this amount of Operational Security. This value was a negotiated amount that the project was able to provide without requiring substantial impact to the energy pricing. The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 15 REQUEST NO.8: Please provide computations showing how the negotiated prices in the Agreement equate to a levelized rate of $71.29 per MWh. RESPONSE TO REQUEST NO.8: Please see the Excel file provided on the enclosed CD. The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 16 REQUEST NO.9: Please compare the rates in the Rockland contract to the prices that were bid in Idaho Powets 2012 Wind RFP wherein no contract was awarded. Please list the total energy price by year for each of the bids received in the 2012 Wind RFP. RESPONSE TO REQUEST NO.9: Bidders in the 2012 Wind RFP requested that the terms and conditions of their bids remain confidentiaL. Even with the confidentiality restriction, an analysis of the bid prices presents sufficient information to address this request for information. Idaho Power received bids from 25 projects, or project configurations, from 14 different bidders in the 2012 Wind RFP. The bids included projects in Idaho, Utah, Wyoming, Montana, Washington, and Oregon. The 20-year levelized prices ranged from approximately $85.00 per MWh to almost $150 per MWh. Sixteen of the 25 project configurations had calculated 20-year levelized costs less than $100 per MWh. All of the calculated 20-year levelized costs include transfer of the RECs, or Green Tags, to Idaho Power. All of the calculated 20-year levelized costs include the estimated transmission charges, if necessary, to deliver the energy to the Idaho Power system. The bid requirement was that the project must be on-line in 2012. All confidential RRP information is available for review at Idaho Power upon execution of a Protective Agreement. The response to this Request was prepared by Tom Noll, Project Manager, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 17 REQUEST NO. 10: Appendix E of the Agreement states that Idaho Power wil make use of a Wind Energy Production Forecasting model to forecast the energy production from the Rockland facilty and other wind QF resources. Has Idaho Power acquired or developed such a model? If so, is Idaho Power currently using the model? What is the estimated cost to Idaho Power of using and maintaining such a model? RESPONSE TO REQUEST NO. 10: In prior Idaho Public Utilities Commission rulings, Idaho Power received authority to make use of a wind forecasting model to estimate wind generation from the various wind projects that were interconnecting to the Idaho Power system and for Idaho Power to collect at least a portion of the cost of that wind forecasting model from the individual wind projects. Initially, Idaho Power had anticipated acquiring a wind forecasting model from one of the recognized industry providers.However, initial inquires indicated that potential costs would be approximately $100,000 for the initial setup, then $2,000-$5,000 for each individual project that forecasting would be required. At the same time, Idaho Power was discussing the wind forecasting needs with internal meteorological personnel and other industry experts. Everyone agreed that the wind forecasting softare suppliers have very sophisticated, state-of-the-art forecasting tools and would most likely be able to provide a more exact wind forecast than a forecast created internally. However, the high supplier cost and the fact that Idaho Power already gathers a lot of weather data for hydro and load forecasting warranted that Idaho Power explore the potential of developing a wind forecast internally. At this time, Idaho Power at an initial cost of approximately $15,000, and an estimated monthly cost of approximately $500, has developed a wind forecasting tool IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 18 that is based on both project specific persistence forecasting and also general weather data. The forecasts have been very acceptable in comparison to other available forecast data from the wind industry suppliers. Idaho Power is currently working with the schedulers and dispatchers to make better use of the forecasting tool in their daily operations. In addition, to take the next step in the wind forecasting model, additional, more detailed weather data is needed. Idaho Power is researching the cost of acquiring that data and the cost/benefit of going to that next step. The historical wind data and ongoing weather data that wil be provided by this Facilty wil be very useful in further develop of an effective wind forecasting tool. The response to this Request was prepared by Randy C. Allphin, Senior Energy Contracts Coordinator, Idaho Power Company, in consultation with Donovan E. Walker, Senior Counsel, Idaho Power Company.
