CASE NO. IPC-E -07- APPLICATION FOR AN ACCOUNTING ORDER COMES NOW, IDAHO POWER COMPANY ("Idaho Power" or the "Company and , pursuant to Rule of Procedure 52, hereby applies to the Idaho Public Utilities Commission ("IPUC" or the "Commission ) for an accounting order authorizing Idaho Power to include the expenses associated with the purchase of energy from Raft River Energy I LLC ("Raft River" or the "Project") in the Company s Power Cost Adjustment. This Application is based on the following: APPLICATION FOR AN ACCOUNTING ORDER, Page BACKGROUND Idaho Power identified a need for geothermal resources in the Company 2004 Integrated Resource Plan ("IRP"). Specifically, the 2004 IRP indicated that Idaho Power would issue a Request for Proposals ("RFP") for 1 00 MW of a geothermal resource in 2005. The Company s 2006 IRP anticipated that the 100 MW geothermal RFP would be concluded in 2007 and that 50 MW of geothermal resource would be online by 2009. The Company issued the geothermal RFP on June 2 , 2006 ("2006 Geothermal RFP" On August 11 , 2006 , in response to the Company s 2006 Geothermal RFP, the Company received nine bids from five entities. The bids ranged in size from 5 to 100 MW. The bids also differed in types of power conversion proposed. Six of the proposals were for binary geothermal technology in which heat from the geothermal fluids is transferred to a secondary working fluid which drives a turbine. The remaining three proposals were for flash units in which hot geothermal fluids are converted to steam that drives a turbine. Six of the nine bids offered long-term power purchase options to the Company. One entity offered to develop three projects that would be sold to Idaho Power. During the fall of 2006 , the Evaluation Team met with each of the five RFP respondents and reviewed the nine proposals offered by those entities. In November 2006, Idaho Power determined that it would not pursue ownership of a geothermal resource. The bidder who submitted ownership proposals was invited to change its bid to power purchase options.That bidder elected to withdraw its proposals from further consideration by the Company. In February 2007 APPLICATION FOR AN ACCOUNTING ORDER, Page 2 the Company chose to negotiate power purchase contracts with U.S. Geothermal , Inc. a Boise-based company. In its bid, U.S. Geothermal, Inc. proposes to offer a total of 45.5 MW of geothermal energy to Idaho Power and to have those facilities online between October 2007 and January 2011. The parties have negotiated and executed a Power Purchase Agreement ("PPA") for approximately 13 MW of the 45.5 MW of geothermal power from Raft River Energy I LLC , an affiliate of U.S. Geothermal , Inc., for its facility known as Raft River Geothermal Power Plant Unit No., located approximately 15 miles southeast of Malta , Idaho. Agreements for the remaining 32.5 MW of power will be submitted to the Commission separately from this filing. The PPA is enclosed as Attachment 1 to this Application. Currently, a Commission-approved PURPA Agreement is in place between Raft River Energy I LLC and Idaho Power for a 10 MW facility at this identical location.(Case No. IPC-05-, Order No. 29692) If the Commission approves the PPA and authorizes inclusion of the power supply expenses associated with the energy from the Raft River Geothermal Power Plant Unit No.1 in the Company s Power Cost Adjustment, Idaho Power proposes that the Company s December 29 , 2004 Agreement with Raft River Energy I LLC entered into pursuant to the Public Utility Regulatory Policies Act of 1978 ("PURPA") be rescinded upon Commission approval of the new PPA and upon satisfaction by Raft River I LLC of all requirements to attain a First Energy Date as specified within the PPA. APPLICATION FOR AN ACCOUNTING ORDER, Page 3 GENERAL DESCRIPTION OF THE RAFT RIVER ENERGY I LLC PPA Raft River Energy I LLC initially guarantees an annual output of 108 186 000 kWh and a 90% capacity factor beginning with the third Contract Year. This annual guarantee may be adjusted periodically based upon an independent engineer s assessment of the status of the geothermal reservoir. Failure to achieve the annual guarantees may result in financial payments to Idaho Power. In addition , the PPA contains Delay Damage provisions that will assess a financial penalty if the Project fails to achieve its scheduled Operation Date of February 2008. Failure to achieve the annual guarantees may result in financial payments to Idaho Power. The term of the PPA is 25 Contract Years (25 years from the Operation Date). Idaho Power has an option to extend the term of the agreement for an additional period mutually agreeable to both parties. Should Raft River Energy I LLC choose to sell its facility, the PPA provides that Raft River first offer to sell its facility to Idaho Power. Under the existing PURPA Agreement for this site , the Project is restricted to providing only 10 MW of energy to Idaho Power. Energy over 10 MW ("Inadvertent Energy ) may be delivered to Idaho Power under the existing PURPA Agreement but no payment is required from Idaho Power for this Inadvertent Energy. The actual geothermal equipment and generation unit under this PPA are identical to the equipment being constructed under the current PURPA Agreement. As part of the negotiations for this PPA, upon approval of this PPA by the Commission , Idaho Power has agreed to retroactively pay for Inadvertent Energy delivered under the PURPA Agreement. The price for the Inadvertent Energy will be the lesser of either 85% of the APPLICATION FOR AN ACCOUNTING ORDER, Page 4 weighted average of Mid C, non-firm on and off peak prices or the monthly PPA price for the applicable months when the Inadvertent Energy was delivered to Idaho Power. If this PPA is not approved by the Commission, the existing PURPA Agreement terms and conditions will remain in effect which include no payments for Inadvertent Energy. 10.The Project, located southeast of Malta , Idaho , is physically connected to the Raft River Rural Electric Cooperative ("RRREC") electrical system and will wheel its energy across the RRREC and Bonneville Power Administration ("BPA") transmission systems to deliver its energy to Idaho Power at the Minidoka substation. As specified in the RFP , Idaho Power requested that all bidders provide and/or secure firm transmission costs within their bids. Because this Project is physically located off of the Idaho Power electrical system it was necessary for this Project to acquire firm transmission across RRREC and BPA's system for the term of the PPA. Idaho Power provides transmission for numerous other BPA loads in the same area. As a result, the PPA allows and Idaho Power contemplates in the future to work with BPA to reduce the BPA transmission costs for this Project. 11.Prices under the PPA will be seasonally adjusted consistent with the seasonality factors currently being used in the Idaho Power PURPA agreements, with the highest rates being paid during the Company s peak energy usage months. The price for energy will start at an annual base rate of $52.50/MWh , escalating annually at a rate of 2.1 % through 2020. For the remaining term, the price for energy will escalate annually at a rate of 0.6% with the resulting energy price in 2032 being $73.92/MWh. In addition to the energy price, a transmission cost of approximately $1.75/MWh will be added to determine the total delivered price per MWh. As stated in item 10 above , it is APPLICATION FOR AN ACCOUNTING ORDER, Page 5 both parties' intent to work with BPA to reduce or potentially eliminate the BPA-related transmission costs. 12.The energy prices within this PPA compare favorably against the prices contained within the PURPA agreement for this same location. Because this PPA has a 25-year term while PURPA agreements have only 20-year terms, a direct comparison of prices under this PPA to PURPA Published Avoided Costs is not available. However the current non-Ievelized PURPA Published Avoided Cost for calendar year 2007 is $52.69 and if the 20th contract year non-Ievelized PURPA Published Avoided Cost escalated at the same rate as previous years , an approximate PURPA price for calendar year of 2032 would be $93.14.In addition to this cost savings, the PPA includes other provisions that are superior to a PURPA agreement including, but not limited to, the receipt of renewable energy credits , forecasting and security provisions and performance assurances. 13.No payment is required by Idaho Power for energy deliveries over maximum contract amounts. The price paid for all energy delivered includes the value of renewable attributes ("Green Tags" or "RECs ) associated with 3 MW of geothermal generation for the first 10 years of the agreement. For the remaining 15 years of the PPA, Idaho Power will receive 51 % of the Green Tags associated with 13 MW of geothermal generation. 14.The PPA requires that Raft River Energy I LLC deliver detailed hourly, daily and weekly forecasting of Net Energy deliveries to Idaho Power Company. If the Project fails to provide timely, reliable and useful forecasts to Idaho Power as detailed and required by this PPA, the PPA contains provisions similar to the 90%-110% delivery APPLICATION FOR AN ACCOUNTING ORDER, Page 6 provisions contained in the Company s current PURPA agreements that will become effective and replace the annual performance requirements within this PPA. 15.The PPA requires the Project to post a $750 000 security deposit by the end of the third Contract Year which will be available for Idaho Power Company to draw upon in the event damages are assessed against the Project. The $750 000 security deposit is required to be maintained for the full term of the agreement which includes replenishment if any withdrawals occur during the term of the PPA. REQUEST FOR FULL COST RECOVERY 16.At the inception of Idaho Power s Power Cost Adjustment (PCA) mechanism , the Commission was concerned that the Company would not have the same degree of incentive to minimize power supply costs than if some degree of cost sharing with customers were retained. As a result, Idaho Power has recovered only 90% of changes from base level net power supply costs through the PCA with the remaining 10% acting as an incentive for efficiency. Although Idaho Power did not have any non-PURPA capacity contracts at the time the PCA was approved in 1993 , the Commission found at that time that "it is appropriate to exclude any future non-CSPP (cogeneration , small power production) firm purchases from the PCA unless the Company has first obtained Commission approval to include them." (Order No. 24806 at 23. 17.Unlike typical wholesale power supply transactions done in day-ahead or real-time markets, Idaho Power has gone through an extensive RFP process to identify the geothermal PPA that will provide the best value to customers. In this docket, the Commission and interested parties will have the opportunity to review reasonableness APPLICATION FOR AN ACCOUNTING ORDER , Page 7 of the RFP's winning bid and the prudency of this proposed PPA's power supply expenses prior to Idaho Power taking delivery of the power. Given the heightened review of this PPA , Idaho Power requests that the Commission authorize 100% recovery of its prudently incurred power expenses associated with this Power Purchase Agreement in the Company s Power Cost Adjustment.Currently no expenses associated with this Power Purchase Agreement are included in base rates. 18.Since the PCA was established in 1993, the Commission has allowed the Company "100% recovery of a resource that it is forced to acquire under federal law. (Order No. 24806 at 17.) Full recovery of the power expenses associated with 10MW of the 13MW encompassed in this PPA are already subject to a Commission-approved PURPA Agreement currently in place between Raft River Energy I LLC and Idaho Power at the same facility.Commission Order No. 29692 issued in Case No. IPC- 05-1 found the PURPA agreement to be reasonable and allowed Idaho Power to recover 100% of the associated expenses in its PCA.Under the new PPA, Idaho Power will continue to purchase the same electrons but at a lower cost to customers. Thus, it is reasonable to allow 100% recovery through the PCA of the proposed PPA in its entirety. 19.In response to customer and Commission feedback, the Company has endeavored to incorporate greater amounts of renewable energy into its Integrated Resource Plans. The Commission has previously indicated its pleasure with Idaho Power s strategy to further diversify and increase the amount of renewable energy sources in its portfolio. (Order No. 29762 at 10 and Order No. 30281 at 12.) Idaho Power believes this geothermal power purchase agreement is precisely the type cost- APPLICATION FOR AN ACCOUNTING ORDER, Page 8 effective renewable power the Commission has encouraged the Company to procure. , following its review the Commission agrees that it is, Idaho Power believes this renewable resource PPA is appropriate for full cost recovery in the Power Cost Adjustment rather than 90%. SERVICE OF PLEADINGS 20.Service of pleadings , exhibits , orders and other documents relating to this proceeding should be served on the following: Lisa D. Nordstrom Barton L. Kline Idaho Power Company O. Box 70 Boise , ID 83707 Ric Gale VP - Pricing and Regulatory Idaho Power Company O.

Upon mutual agreement as to the quantity of energy delivery reduction, the Annual Guaranteed Output shall be adjusted accordingly. Energy Delivery Guarantee, Reconciliation, and Net Energy Shortfall Determination. Seller guarantees that the Total Annual Facility Net Energy shall equal or exceed the Annual Guaranteed Output for each period during the Initial Term of this Agreement beginning with March 1, 2010. The determination of whether Seller has met its Annual Guaranteed Output requirement shall be made on an annual basis beginning on March 1 , 2011 by comparing the amount of the previous twelve (12) month's Total Annual Facility Net Energy to the Annual Guaranteed Output as provided for in this Section. 1 If the Total Annual Facility Net Energy is equal to or greater than the Annual Guaranteed Output in the applicable period, Seller shall be deemed to have met its Annual Guaranteed Output obligation for that period, and Seller shall have obligation to pay Net Energy Shortfall Damages or to true-up PAGE 19 OF 50 POWER PURCHASE AGREEMENT - RAFf RIVER ENERGY 09120/07 energy delivery obligations with respect to that period. Any Net Energy delivered during this period exceeding the Annual Guaranteed Output may be used to make up the previous period Net Energy Shortfall if one exists. If the Total Annual Facility Net Energy is less than the Annual Guaranteed Output for a specified period, then a Net Energy Shortfall exists and is equal to the Annual Guaranteed Output minus the Total Annual Facility Net Energy. The Net Energy Shortfall may be made up in the subsequent twelve (12) month period beginning at March 1. Net Energy delivered during the immediately following twelve (12) month period in excess of the Annual Guaranteed Output for that period may be used to make up the previous period's Net Energy Shortfall. At the end of the subsequent twelve (12) month period, if the Net Energy Shortfall has not been made up, then any remaining Net Energy Shortfall Damages will be calculated based upon any remaining balance of the Net Energy Shortfall and a billing will be presented to the Seller which the Seller will be required to pay the Buyer within fifteen (15) days of the date of the billing notice. Any remaining Net Energy Shortfall at the end of the Initial Tenn of this Agreement will be payable to the Buyer within fifteen (15) days of the date of the billing notice being provided to the Seller. Effect of A?pendix D on Net Energy Shortfalls and Net Energy Shortfall Damages . At the time Appendix D is implemented, the current year Net Energy deliveries shall be compared to the Annual Guaranteed Output on a pro-rata basis for the current Annual Guarantee Output period. If there is a Net Energy Shortfall, then Net Energy Shortfall Damages shall be calculated. If there have been Net Energy deliveries in excess of the pro-rated Annual Guaranteed Output, then the excess Net Energy may be applied to any Net Energy Shortfall from the previous Annual Guarantee Output period. Any Net Energy Shortfall Damages due shall be billed by Buyer to Seller and shall be due within fifteen (15) days of the presentation of the billing. Upon implementation of Appendix , all Net Energy Shortfall calculations will be suspended until such time as this Agreement is terminated or application of Appendix D rescinded. Seller s Reversion Rights. At any time after Appendix D takes effect, Seller may from time to time propose to Buyer forecasting information and/or processes that are in accord with Good Utility Practice(s). The proposed forecasting process shall be subject to Buyer s approval , which Buyer shall not unreasonably withhold, condition or delay. If the proposed forecasting process is approved by Buyer, Appendix D shall cease to be effective as of the first day of the calendar month following such approval (or as otherwise agreed by the Parties). If Appendix D ceases to be effective pursuant to this Section 7.7 all Sections of this agreement previously suspended due to Appendix D becoming effective shall become operative again (including the right to invoke PAGE 20 OF 50 POWER PURCHASE AGREEMENT - RAFr RIVER ENERGY -09/20/07 Appendix D), with Total Annual Facility Net Energy to be tested against Annual Guaranteed Output prorated for the months remaining in the current AnnualGuaranteed Output period and for all full Annual Guaranteed Output periods thereafter. Buyer Adjustment of the Annual Guaranteed Output The Buyer shall be excused from accepting and paying for Net Energy and Test Energy produced by the Facility and delivered by the TransmittingEntity to the Point of Delivery if it is prevented from doing so by an event of Force Majeure, or if the Buyer determines that curtailment, interruption or reduction of Net Energy or Test Energy deliveries is necessary because of line construction or maintenance requirements, emergencies , electrical system operating conditions on its system or as otherwise required by Good Utility Practice(s) provided that during such curtailment, interruption or reduction the Buyer, the Transmitting Entity and the Seller shall within reasonable limits attempt to coordinate, schedule and deliver Net Energy to the Buyer s electrical system at other points of delivery if the Buyer is capable of accepting the Net Energy deliveries at other points of delivery at no additional cost to the Buyer. The Buyer shall not curtail Net Energy or Test Energy deliveries from the Seller s Facility due to economic dispatch. If the Buyer requires a curtailment of the Facility s Net Energy or Test Energy deliveries to the Point of Delivery, any such curtailment shall not exceed the Facility s pro-rata contribution to the event causing the curtailment. For example - if 500 MW of generation resources are making use of the same firm transmission path and a 50 MW curtailment is required on this transmission path, the Facility will be required to curtail no more then 10% (50 MW /500 MW) of its actual energy production at the time the curtailment event occurs. 1.1 If, for reasons other than an event of Force Majeure, the Buyer requires curtailment, interruptions or reductions of Net Energy deliveries for a period that exceeds twenty (20) days , beginning with the twenty-first (21st) day of such interruption, curtailment or reduction, Sellerwill be deemed to be delivering Net Energy at a rate equivalent to the daily average of the Net Energy deliveries that were occurring during the immediately proceeding twenty-four (24) hour period prior to the curtailment. Buyer will notify Seller when the interruption, curtailment or reduction is terminated. If the Buyer is excused from accepting and paying for Net Energy as allowed within this Agreement or the Seller is prevented from delivering Net Energy to the Buyer as provided for in this Agreement, the Seller may attempt to sell all or a portion of the Net Energy to another party. 3 If the Buyer is required to reduce Net Energy deliveries to the Buyer from the Seller s Facility as described in Section 7., the Annual Guaranteed Output for the impacted Annual Guaranteed Output period( s) will be revised to reflect the reduction of Net Energy deliveries that were a direct result of the Buyer s need to reduce Net Energy deliveries. PAGE 21 OF 50 POWER PURCHASE AGREEMENT - RAFT RIVER ENERGY 09120/07 Requirements for the Addition of New Geothermal Energy Uses Seller may add additional uses of geothermal energy controlled by Seller or available for Seller s use, subject to the terms of this Section 7. Certification of Geothermal Energy Sufficiency.Prior to allowing each new geothermal use(s) to be built and delivery of geothermal energy to commence to the new geothermal use(s), an independent licensed geothermal reservoir engineer shall certify that for the remaining Term of this Agreement and in the professional judgment of this engineer, the geothermal energy production capability of the geothermal resource controlled by Seller or available for Seller s use is sufficient to supply at least one hundred percent (100%) of the geothermal energy requirements of (1) the Facility, (2) the existing other use(s) of geothermal energy, and (3) the proposed new use(s) of the geothermal energy. The independent engineer shall be selected by Seller and shall be reasonably acceptable to Buyer.

Allocation of Geothermal Energy Shortfalls.If during the Term of this Agreement, the geothermal energy controlled by Seller, or available for Seller s use is unable to provide the Facility and the additional geothermal use(s) installed per the requirements of Section 7.1 with adequate geothermal energy to maintain operations of all of the geothermal use(s) at full design capacity, then Seller shall allocate the geothermal energy between the Facility and the additional geothermal use(s) installed per the requirements of Section 7.1. The allocation shall be pro-rata between the Facility and the other use(s), based on the percentage of their particular design geothermal energy usage rates compared to the total design geothermal energy usage rate of the group. Geothermal energy use(s) that utilize waste heat from the Facility or from other user(s) shall be excluded from the above pro-rata allocations. A pro-ration of the geothermal resource shall not be required if so doing requires capital investment by the Seller with a negative net present value. 10 Title and Risk of Loss. As between the Parties , Seller shall be deemed tobe in control of the energy output from the Facility up to and until delivery and acceptance at the Point of Delivery by the Buyer. Title and risk of loss related to the energy shall transfer from Seller to Buyer at the Point of Delivery. 11 Station Energy. This Agreement does not require Buyer to supply any electric service to the Seller or to the Facility. Seller shall enter into separate arrangements for the supply of electric services to the Facility. Seller is responsible for causing these electric services to be available before the First Energy Date. Seller will specifically design the Facility to ensure that no energy purchased for supply of electric PAGE 22 OF 50 POWER PURCHASE AGREEMENT - RAFf RIVER ENERGY 09120/07 energy to the Facility is delivered to the Buyer by the Transmitting Entity as Net Energy or Test Energy. 12 Buyer s Failure to Take Energy Except as expressly provided by Section 7., if the Buyer fails to accept all or part of the energy that the Facility is able to generate and the Transmitting Entity is able to deliver to the Point of Delivery after the Operation Date that is less than the Maximum Capacity, and such failure is not excused under the terms of this Agreement then (1) For energy from the Facility that is sold to another party, Buyer shall pay Seller an amount equal to the positive difference, if any, obtained by subtracting the sales price obtained by the Seller from selling the energy to another party, from the Contract Price for such energy, or (2) For any amount of energy which the Seller is capable of generating but is unable to sell to either the Buyer or another party, Buyer shall pay Seller the Contract Price plus the applicable PTC Value plus the value of the Environmental Attributes that would have gone to the Seller with respect to all energy not received. Each payment under this Section shall be due for the month in which the failure occurred or within fifteen (15) Business Days after Buyer receipt of an invoice. The invoice for such amount shall include a written statement explaining in reasonable detail Seller s calculation of the energy that would have been delivered to Buyer but for Buyer s failure to receive it and the amount due. ARTICLE 8 TRANSMISSION AGREEMENT Transmission Agreement.The Seller will arrange and pay for the delivery of Test Energy and/or Net Energy over the facilities of the Transmitting Entities (BP and the RRREC) to the Point of Delivery.

The RRGPP-l is an Ormat OECTM water-cooled, closed-loop, Rankine cycle geothermal power plant using pentane as the working fluid, and auxiliary equipment. The Facility includes two Ormat turbines (one HP (high pressure) and one LP (low pressure) turbine) coupled to a single generator with a gross nameplate rating of 18 MW, and a generator voltage of 12.47 kV. Power will be delivered to the Transmitting Entity on the high side of the 34.5kV step-up transformer through the Idaho Power Metering. Each turbine discharges to a 2-shell condenser and is fed by a 2-shell vaporizer with a 2-shell pre- heater and two feed pumps using geothermal fluid as the heat source. The HP turbine has a desuperheater/economizer between the turbine and the condenser. Cooling water will be supplied by two circulating water pumps in the basin of a four-cell counterflow cooling tower. The Facility is protected by a fire water system comprising fire water pumps, pipes , monitors, and so on. Geothermal fluid will be delivered to the Facility from four or more geothermal production wells. Residual geothermal fluid will be reinjected via two or more injection wells. LOCATION OF FACILITY The Facility is located at: Section 23, Township 15 South, Range 26 East, Cassia County, Idaho. Approximately 15 miles SE of Malta, ill. The area is commonly known as the Raft River Geothermal Resource Area and is the site of a former 5 MW DOE binary geothermal power plant test site.

Definitions. The following defined terms (as indicated by initial capitalization) shall have the meaning given to them in this Appendix. Surplus Energy Price" - For all Surplus/Shortfall Energy, Buyer shall pay to the Seller the current month's Market Energy Price or the Contract Price specified in Appendix A of this Agreement, whichever is lower. Surplus/Shortfall Energy" is defined as either (1) Net Energy produced by the Seller Facility and delivered to Buyer pursuant to this Agreement during the calendar month to the extent such Net Energy exceeds one hundred ten percent (110%) of the monthly Net Energy Target for the corresponding calendar month specified pursuant to this Appendix, or (2) if the Net Energy produced by the Seller s Facility and delivered to Buyer pursuant to this Agreement during the calendar month is less than ninety percent (90%) of the monthly Net Energy Target for the corresponding calendar month specified pursuant to this Appendix, then all Net Energy delivered by the Facility to the Buyer s electrical system for that given month. Initial Date" - is defined as the first day of the calendar month following the date on which the Seller fails to timely cure a default as detennined under Section 7.4.2 and the terms and conditions within this Appendix are therefore implemented in lieu of Sections 7.4 and 7.5 of the Agreement. Initial Year" - is defined as twelve (12) calendar months starting with the Initial Date. PAGE 1 OF 2 - APPENDIX D TO POWER PURCHASE AGREEMENT - RAFf RIVER ENERGY I/IPC Net Energy Target" is defined as the monthly Net Energy that the Seller intends to produce and deliver to the Point of Delivery as specified pursuant to this Appendix. Initial Year Monthly Net Energy Targets - This term shall have the meaning given to it in Section 3 below. 3. Monthly Net Enerey Tareets Seller shall provide the Buyer with the monthly Net Energy Targets for the Initial Year within thirty (30) days after the Initial Date (the "Initial Year Monthly Net Energy Targets ). If the Seller does not provide the Initial Year Monthly Net Energy Targets as specified, ninety percent (90%) of the Facility s nameplate rating multiplied by the hours for each month will be used to establish each month's Net Energy Target for the Initial Year (subject to adjustment under Section 5 of this Appendix). 4. Oneoine Monthly Net Enerey Tareets - Beginning at the end of the ninth (9th month following the Initial Date and every three (3) months thereafter, the Seller shall provide Buyer with a minimum of three additional calendar months of Net Energy Targets. This infonnation will be provided to Buyer by written notice in accordance with Article 33 , no later than the fifth (5th) day following the end of the previous month. If the Seller does not provide the Ongoing Monthly Net Energy Targets in a timely manner, Buyer will use the monthly production (actual or, if actual numbers are not available, calculated as contemplated in Section 9.3) for the same three (3) months period in the preceding year. 5. Seller s Adjustment of Net Enerey Tareet(s)- Except as provided herein beginning with the end of the third (3f ) month after the Initial Date and at the end of every third(3fd) month thereafter, the Seller may not revise the immediate next three (3) months of previously provided Net Energy Targets.

If this Net Energy Shortfall Price calculation results in a value less than zero (0) then the result will be zero (0). Example 1 A Net Energy Shortfall occurs for the year of March 1 2009 through February 28 2010 Annual Rate 54.73 millslkWh Mathematical average of the 12 monthly Market Energy Cost values for the period of March 1 2009 through February 28 2010 40.00 millslkWh 150% of the Annual Rate 54.73 * 150% = 82.10 millslkWh Net Energy Shortfall Price calculation The average Market Energy Cost (40.00) is less than 150% of the Annual Rate (82.10). Therefore the Net Energy Shortfall Price calculation is equal to: Market Energy Cost (40.00) minus Annual Rate (54.73) = -14. As the calculation results in a value less than 0 , (- 14.73) the Net Energy Shortfall price is O.

Therefore the Net Energy Shortfall Price calculation is equal to: Market Energy Cost (75.00) minus Annual Rate (54.73) = 20. 20.27 is the Net Energy Shortfall Price Example 3 A Net Energy Shortfall occurs for the year of March 1 2009 through February 28, 2010 Annual Rate 54.73 millslkWh Mathematical average of the 12 monthly Market Energy Cost values for the period of March 2009 through February 28 2010 98.00 millslkWh 150% of the Annual Rate 54.73 * 150% = 82.10 millslkWh Net Energy Shortfall Price calculation The average Market Energy Cost (98.00) is greater than 150% of the AnnualRate (82.10). Therefore the Net Energy Shortfall Price calculation is equal to: 150% of Annual Rate (82.10) minus Annual Rate (54.73) = 27. 27.37 is the Net Energy Shortfall Price PAGE 2 OF 3 - APPENDIX E TO POWER PURCHASE AGREEMENT - RAFT RIVER ENERGY UIPC Net Enerey Shortfall Damaees Cap Contract Net Energy Contract Net Energy Year Shortfall Year Shortfall Damages Cap Damages Cap $0.$415,270 $0.$427 728 $300,000 $440,560 $309,000 $453,777 $318,270 $467 390 $327 818 $481,412 $337 653 $495,854 $347 782 $500,000 $358,216 $500,000 $368,962 $500,000 $380,031 $500,000 $391 ,432 See Note 1 $403,175 Note 1 - The Net Energy Shortfall Damages Cap in the final year shall be $500,000 prorated to the number of months in the Annual Output Forecast.
