RESPONSE TO REQUEST NO.1: Please see the following documents provided on the non-confidential CD: · Operating Agreement dated October 15, 1976; . Amendment dated September 30, 1977; . 2nd Amendment dated October 31, 1977; . Amendment dated January 23, 1978; . 3rd Amendment dated February 15, 1978; · Letter Agreement (Section 18) dated September 1, 1979; · Letter Agreement (Section 9) dated September 1, 1979; and . Amendment dated September 1, 1979. The response to this Request was prepared by Courtney Waites, Regulatory Analyst, Idaho Power Company, in consultation with Jason B. Wiliams, Corporate Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 2 REQUEST NO.2: Related to the Boardman shut-down plan, please provide the following: a. Factors driving early shut down; b. A list of parties participating in the discussions, and c. Explanations and copies of all analyses conducted by IPC pertaining to evaluation options considered with early shut down and the Consent Decree. (Case No. 3:08-CV-01136-HA in the U.S. District Court for the District of Oregon, Portland Division). RESPONSE TO REQUEST NO.2: a. The process to develop a Boardman shutdown plan started with the implementation of the Regional Haze Best Available Retrofit Technology ("RH BART") rule. The RH BART rule was adopted in July of 1999 with the objective of returning the visibility in national wilderness areas to a natural background level by 2064. This started by identifying the largest impacts to the visibilty of the wilderness areas during the RH BARTphase (the first five years). Boardman was identified as having impacts to the visibilty in wilderness areas, such as Crater Lake National Park and Mount Hood wilderness areas, along with the other 10 wilderness areas in Oregon. These impacts would require pollution controls as identified by the state to meet RH BART during this first phase and Reasonable Progress during the next phase of RH BART. Even though the Columbia Gorge is not a wilderness area and not part of this rule, there wil also be positive visibilty impacts to this area. On June 19, 2009, the Oregon Environmental Quality Commission ("OEQC") adopted the Boardman requirements as follows: IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 3 Regional Haze: · Low NOX burners and Over Fire Air (Nitrogen Oxide) o 0.23 Ib/mmBtu by 2011 · Selective Non-Catalyst Reduction (Nitrogen Oxide) by 2014 · Semi-Dry Scrubber (Sulfur Dioxide) o 0.12 Ib/mmBtu by 2014 · Baghouse (Particulate Matter) o 0.012lb/mmBtu by 2014 Reasonable Progress Requirements: · Selective Catalyst Reduction (Nitrogen Oxide) o 0.07 Ib/mmBtu by 2018 Because of pending and proposed legislation on carbon emissions, and the uncertainty of future emissions restrictions on other pollutants, Portland General Electric ("PGE") was concerned that the plant could become uneconomic to run in the future. PGE proposed a closure date to the Oregon Department of Environmental Quality ("ODEQ") through December 2020 without installng a scrubber and selective catalytic reduction as meeting the economic criteria and stil meeting the requirements of RH BART and Reasonable Progress. The ODEQ proposed the following new RH BART requirements: · Low NOX burners and Over Fire Air (Nitrogen Oxide) o 0.23 Ib/mmBtu by 2011 . Dry Sorbent Injection (Sulfur Dioxide) o 0.40 Ib/mmBtu by 2014 o 0.30 Ib/mmBtu by 2018 · Activated Carbon Injection (Mercury) (Oregon Utilty Mercury Rule) o 0.6 IblTBtu or 90 percent removal by 2012 There are no Reasonable Progress requirements for the plant because of the 2020 shutdown. The new RH BART agreement was proposed by the ODEQ, which was adopted and approved by the OEQC and incorporated into the Oregon State Implementation IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 4 Plan ("SIP"). The OEQC is the policy and rulemaking board for the state of Oregon. The SIP was approved by the Environmental Protection Agency ("EPA") effective August 4, 2011. b. The parties participating in the discussions were the public, Citizens' Utilty Board of Oregon, Sierra Club, Greenpeace, Friends of the Columbia Gorge, PGE, Idaho Power, and environmental groups. c. To evaluate the economic impact of the various early closure scenarios, Idaho Power compared the expected present value revenue requirement ("PVRR") to operate the existing Boardman plant to 2040 with additional pollution control investments as required per the ODEQ's RH BART rules versus the revenue requirements for the various early closure alternatives (which contained a smaller suite of pollution control requirements). For the early closure scenarios, the analysis incorporated the value of replacement power from the proposed closure date through 2040 to allow for an equivalent 30-year present value comparison against the "install the full suite of retrofits and run the plant to end of life" scenario. Carbon assumptions from Idaho Powets 2011 Integrated Resource Plan ("IRP") were assumed in the analysis as welL. The replacement resource assumed in the analysis was a combined-cycle, combustion turbine plant. Several iterations of PVRR comparisons were made as Idaho Power was made aware of potential closure scenarios that were being considered by PGE and its regulators/intervenors. As a smaller minority owner in Boardman, Idaho Powets approach was to stay "plugged in" as the various scenarios/options were being discussed and to perform revenue requirement impact analyses in an effort to validate PGE's conclusions and position throughout the process. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 5 The confidential summary provided on the confidential CD analyzes the cost of installing the smaller suite of pollution control retrofits and decommissioning the plant in 2020, as now required in the sip and approved by the EPA. The document also lists the various inputs and analysis assumptions. Given the assumed carbon future indicated in Idaho Powets 2011 IRP and replacing Boardman with new gas-fired base load generation, decommissioning the plant in 2020 or even sooner is slightly less costly than the estimated cost to customers to install the more comprehensive list of pollution control investments and run the facilty to 2040. While an earlier than 2020 closure date may have proven to be slightly more favorable for Idaho Power, PGE did not make the same conclusion, primarily due to the difficulty it would have replacing its larger share of Boardman generation in such a short time frame with market purchases or new generation. The confidential summary wil be provided to those parties that have executed the Protective Agreement in this matter. There were no additional Idaho Power analyses performed for the evaluation of the Consent Decree. The response to this Request was prepared by Tom Harvey, Joint Projects Manager, and Randy Henderson, Finance Team Leader ", Idaho Power Company, in consultation with Jason B. Willams, Corporate Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 6 REQUEST NO.3: Please explain the Company's involvement in this process. RESPONSE TO REQUEST NO.3: Idaho Power was involved in the Boardman RH BART process in the following ways: · Teleconferences and meetings between Idaho Power and PGE officials to discuss the status and strategy PGE was pursuing; . Idaho Power ran various financial analyses to determine whether various options were beneficial to Idaho Power; . Idaho Power attended most of the public meetings with the ODEQ and OEQC; and . Idaho Power retains an attorney specializing in environmental law and reviewed the ongoing RH BART process with this attorney. The response to this Request was prepared by Tom Harvey, Joint Projects Manager, Idaho Power Company, in consultation with Jason B. Willams, Corporate 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: Please explain why the Consent Decree is the best outcome for Idaho customers. What benefits wil be experienced/received by Idaho customers? RESPONSE TO REQUEST NO.4: In determining whether to settle the lawsuit, PGE and Idaho Power compared the probabilty and cost of a potential judgment (which included an evaluation of potential penalties imposed by the EPA, the costs of upgrades that would have to be made at the Boardman facilty if the plaintiffs prevailed, and the substantial amount in attorneys' fees and costs necessary for a defense) against the settlement offer set forth by the plaintiffs. In the end, PGE and the Company determined that the settlement terms constituted the best resolution of the lawsuit in light of the inherent risks and uncertainties related to the litigation process and the current regulatory environment. Idaho Power attended the mediation and provided feedback related to various potential outcomes. Idaho Power believes the settlement amount wil not have a material adverse effect on Idaho Power's financial position, results of operations, or cash flow. Accordingly, compared to the risks associated with continued litigation of this matter, Idaho Power believes the Company and its customers are better off in having settled this litigation. The response to this Request was prepared by Adam Richins, Corporate Counsel, Idaho Power Company, in consultation with Jason B. Wiliams, Corporate Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 8 REQUEST NO.5: Please provide a schedule showing the historical actual operation of the Boardman power plant and power taken by the Company in the last 5 years. Please also show the projected operation of the plant through closure and expected power to be received by the Company. RESPONSE TO REQUEST NO.5: Please see the confidential PDF file provided on the confidential CD. The confidential CD wil be provided to those parties that have executed the Protective Agreement in this matter. The response to this Request was prepared by Tom Harvey, Joint Projects Manager, Idaho Power Company, in consultation with Jason B. Wiliams, Corporate 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.6: Please provide the cost/benefit analysis related to the emission controls to be installed. Please also list all the clean air requirements or possible requirements that wil be met with each installation. Please provide a tabular summary of the different state and federal environmental regulations that are driving environmental/emission control investments at the Boardman plant and the corresponding pollutants they intend to control (and at what level). Please include the approximate cost of each investment. RESPONSE TO REQUEST NO.6: Please see the Company's response to Staff's Production Request No. 2 above for a discussion of the cost/benefit analyses related to Boardman emissions controls. Emission controls that are being installed at Boardman are the result of the following state and federal regulations: . Regional Haze Best Available Retrofit Technology Low NOX burners and Over Fire Air (Nitrogen Oxide) Total capital cost approximately $24 milion 0.23 Ib/mmBtu by 2011 Dry Sorbent Injection (Sulfur Dioxide) Total capital cost approximately $29 milion 0.40 Ib/mmBtu by 2014 0.30 Ib/mmBtu by 2018 . Oregon Utility Mercury Rule Activated Carbon Injection (Mercury) Total capital cost approximately $6 milion 0.6 IblTBtu or 90 percent removal by 2012 The Utilty Maximum Achievable Control Technology ("Utilty MACT") rule is expected to be finalized in December 2011. When the rule is finalized and after testing is completed and evaluated, it wil be determined if the controls listed above wil help meet the Utility MACT rule. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 10 The response to this Request was prepared by Tom Harvey, Joint Projects Manager, Idaho Power Company, in consultation with Jason B. Willams, Corporate Counsel, Idaho Power Company. IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 11 REQUEST NO.7: Please explain the process to explore the possibilty of obtaining waivers for a plant that wil be retired. Were any requests made? RESPONSE TO REQUEST NO.7: PGE met with its congressional delegation and the EPA to discuss the possibilty of a waiver from the Utilty MACT rule for plants that have a determined shutdown date. PGE also provided comments to the EPA during the comment period of the Utilty MACT rule proposing that plants with a determined shutdown date be exempt from the rule. The final Utilty MACT rule is expected to be issued in December 2011. No other waivers have been identified for early closure plants. The response to this Request was prepared by Tom Harvey, Joint Projects Manager, Idaho Power Company, in consultation with Jason B. Willams, Corporate 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.8: Please provide a list of each type of cost liabilties (and estimates) that wil be booked to the balancing account related to the shutdown (i.e. what expenses and what share of expenses). RESPONSE TO REQUEST NO.8: The type of cost liabilties (and estimates) that wil be booked to the balancing account related to the shutdown of Boardman wil consist primarily of Asset Retirement Obligation ("ARO") estimates, partially offset by expected salvage proceeds, associated with the decommissioning of the plant. The ARO related to Boardman currently considers costs to decommission and remove plant components, including the power plant and associated facilties, the Carty reservoir (reservoir supporting the operations of the plant), certain transmission lines, tower access road, ash field capping or removal, and coal handling facilties. Also, currently included in the ARO calculation is a 10 percent contingency estimate. Idaho Power expects to share the expenses to decommission the plant in proportion to Idaho Power's ownership share in the Boardman plant, which is 10 percent. In addition to the net decommissioning costs, the balancing account would also include the revenue requirement, on a levelized basis, associated with the accelerated recovery of existing investment and the incremental capital investment expected between 2012 and 2020. The response to this Request was prepared by Randy Henderson, Finance Team Leader ", and Tim Tatum, Manager of Cost of Service, Idaho Power Company, in consultation with Jason B. Willams, Corporate 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.9: Please provide an analysis of all alternatives considered by Idaho Power along with the proposed balancing account method for accounting for the costs. What are the pros and cons of each alternative? RESPONSE TO REQUEST NO.9: As Idaho Power developed its preferred approach for recovering the costs associated with the early shutdown of the Boardman plant, it considered three fundamental objectives: (1) timely cost recovery, (2) rate stabilty, and (3) the proper matching of costs and benefits. While there are a number of methods that could be applied to simply recover the costs associated with the early shutdown of the Boardman plant, the Company identified only one approach that effectively satisfies each of the three objectives. The Company's preferred approach to recovering these costs uses a balancing account to track the recovery of the levelized revenue requirement related to accelerated recovery of existing investment and the nine-year forecast of incremental costs of early shutdown. These costs include capital investments forecasted through the remaining life of Boardman, the costs of accelerating the depreciation of the existing Boardman plant items, and the decommissioning costs. The levelized revenue requirement would be determined by calculating the present value of each of the cost components assuming a level payment stream from customers over the next nine years. The Company is proposing to begin tracking the costs associated with the Boardman early shutdown in a balancing account starting January 2012 with inclusion of the incremental change to the revenue requirement included in customer rates on June 1, 2012. Idaho Power envisions an annual review with adjustment to the level of IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 14 recovery to the balancing account to address significant changes if they occur. Any overage or shortall in the collection of the previous year's incremental revenue requirement would be incorporated into a new levelized incremental revenue requirement calculation when necessary. Current customers wil receive the benefit of the time value of money for paying costs associated with the early shutdown of Boardman in advance while also benefiting from a rapidly declining plant balance. This wil also potentially limit large rate increases related to decommissioning costs anticipated upon Boardman's closure.These same customers are currently experiencing the benefits of the Boardman plant as a lower-cost base load resource. The balancing account approach accomplishes the goal of matching costs and benefits and ensures customers are not paying beyond the useful life of the plant. It also provides rate stability and ensures customers pay no more than the true costs of the shutdown. Alternatives to the proposed levelized recovery using a balancing account, such as methods using annual filings to adjust rates to reflect the incremental annual investments, would not achieve all three of the Company's objectives. These more "traditional" methods would result in shorter recovery times and potential large, one time increases. Further, a more traditional approach would likely require cost recovery beyond the useful life of the plant, resulting in a mismatching of cost recovery and associated benefits. The response to this Request was prepared by Tim Tatum, Manager of Cost of Service, Idaho Power Company, in consultation with Jason B. Wiliams, Corporate 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. 10: Please explain Idaho Powets proposal/expectation/projection related to total dollar amounts to be reflected in the balancing account over the remaining life of the Boardman facilty, timing and amortization period for the balancing account, and magnitude of the expected amounts to be included in rates. Include current investment, future investment, decommission costs, salvage values and amortization amounts. RESPONSE TO REQUEST NO. 10: Idaho Power expects that costs associated with the decommissioning of the Boardman facility (primarily what makes up the ARO), estimated salvage proceeds (these first two components are also referred to as net decommissioning costs), and future investment in the Boardman facilty wil be components that would be included in the balancing account. Current investment in the Boardman facilty, through December 31, 2011, is currently being considered in the depreciation study that is being performed. Idaho Power expects that the revenue requirement associated with the above-mentioned costs would be included and tracked utilzing the balancing account. Idaho Power would anticipate that this revenue requirement would be re-evaluated annually, and that any overage or shortall in the revenue requirement from the previous year would be incorporated into the calculation for the revenue requirement to be levelized over the remaining period to December 31, 2020. On December 31, 2020, revenue collections would stop, and the existing and future investment balances would be fully depreciated, leaving only the net decommissioning costs to be considered. Subsequent to December 31,2020 (primarily in 2021 and 2022), the amounts collected pertaining to the net decommissioning costs would continue to be compared to estimated costs, and any overage or shortall would IDAHO POWER COMPANY'S RESPONSE TO THE FIRST PRODUCTION REQUEST OF THE COMMISSION STAFF TO IDAHO POWER COMPANY - 16 be tracked in the balancing account. Upon final resolution of all decommissioning activities, Idaho Power would request that any overage or shortall in the balancing account (by design, there should be minimal difference) would then be returned to or collected from ratepayers. Please see the Excel spreadsheet, "Incremental Revenue Requirement for Proposed Early Boardman Plant Shut-Down," provided on the non-confidential CD for details on the general magnitude of the expected amounts to be included in rates. These calculations provide the framework and an ilustration for how the levelized amounts would be determined. Cost estimates, calculations, and assumptions would be further refined as part of the initial balancing account filng.
