IPC-06- COMES NOW , Idaho Power Company ("Idaho Power" or the "Company ) and , in accordance with RP 052 and RP 201 et seq.hereby requests that the Commission issue its order approving the Generation Interconnection Agreement ("GIA") between Bennett Creek Windfarm LLC ("Bennett Creek") and Idaho Power. This Motion is based on the following: The Commission has previously approved a Firm Energy Sales Agreement between Idaho Power and Bennett Creek Windfarm (Order Nos. 30245 and 30399). A copy of the Bennett Creek GIA is enclosed as Attachment No. 1. 1 The GIA covers both the Bennett Creek and Hot Springs Windfarm projects because a single interconnection will be built to interconnect both projects and both projects are being developed by the same developer. MOTION - 1 Idaho Power has filed this Motion for two reasons. First, this GIA is the first interconnection agreement involving the Public Utility Regulatory Policies Act of 1978 PURPA") generating facilities subject to Idaho Power s Schedule 72 which involves substantial upgrades to Idaho Power s transmission system. Second, the allocation of costs from the transmission upgrades for the Bennett Creek project were not addressed in Commission Order No. 30414 in Case No. IPC-06-21 ("the Cassia Windfarms' case In the Cassia Windfarms' case , the Commission approved a settlement which implemented a cost-sharing arrangement under which Idaho Power will contribute twenty-five percent (25%) of the cost of the needed transmission upgrades , Cassia Windfarms will make a non-refundable 25% contribution in aid-of-construction ("CIAC") to support the transmission upgrades and Cassia Windfarms will make an advance in aid-of- construction ("A lAC") for the remaining balance of the cost of the upgrades. The AIAC will be refunded to Cassia Windfarms over time if they fully perform their Firm Energy Sales Agreements with Idaho Power. For purposes of this Motion , the 25%/25%/50% cost sharing arrangement will be referred to as the "Cassia Formula In Order No. 30414, the Commission concluded that use of the Cassia Formula was appropriate for the Cassia Windfarms as well as the other PURPA generation projects in the Twin Falls 138 kV transmission queue. However, the Commission did not authorize the Company to automatically apply the Cassia Formula in other locations on its system where transmission upgrades would be required. The Commission indicated that application of any terms or conditions approved as a part of the settlement in the Cassia Windfarms case to other Qualifying Facility ("QF") interconnection requests "will depend on the specific characteristics of that situation." (Order No. 30414 p. 11). In the GIA between MOTION - 2 Bennett Creek and Idaho Power, the parties have agreed to apply the Cassia Formula to share the costs of the transmission upgrades for the Bennett Creek Windfarm. In concluding that it is appropriate to use the Cassia Formula for sharing costs of transmission upgrades for Bennett Creek, Idaho Power applied the Commission findings and conclusions in Order No. 30414 as follows: (1 )But for the construction of the Bennett Creek Windfarm , Idaho Power would not have constructed the transmission upgrades described in Attachment 1 to provide adequate service to its native load customers. Therefore , a contribution by the developer of a portion of the transmission upgrade cost is appropriate. (2)Idaho Power believes that in Order No. 30414 , the Commission directed Idaho Power to assess the benefits of individual transmission upgrades taking into consideration "the system wide benefits that accrue to all customers on an integrated transmission grid". (Order No. 30414 p. 10). One way to approach that assessment is to compare the level benefits that the Bennett Creek upgrades will provide to the system with the level of benefits provided in the Cassia Windfarms case. The Company acknowledges that it is nearly impossible to precisely quantify the relative system benefits conferred by two distinct and geographically separate transmission upgrades. However, transmission engineers can exercise their judgment and their knowledge of transmission systems they have designed and operate.Based on their informed judgment, Idaho Power transmission engineers are of the opinion that the transmission upgrades identified in Attachment 1 will provide different benefits than the transmission system benefits the Cassia Windfarms upgrades will provide. Where the Cassia Windfarms upgrade will install a new transformer to interconnect the 230 and 138 kV MOTION - 3 transmission systems in the western portion of the Magic Valley, the improvements contemplated herein will upgrade (replace the line conductor) and update (replace poles, insulators and hardware not capable of supporting the larger conductor) an older transmission line. Some facilities on the line interconnecting the Bennett Creek project may have been providing service since 1921. The use of the Cassia Formula is reasonable in this circumstance. (3)The Company is also of the opinion that the application of the Cassia Formula in this case will maintain the balance between "the benefits accruing to the customers of the grid with the cost responsibility of the QF necessitating the timing and the construction of the upgrade." (Order No. 30414 p. 11). (4)Bennett Creek, like the QF projects in the Twin Falls queue, will displace or defer the need for other or similar generation projects in the Company Integrated Resource Plan that would likely require related transmission investment by the Company. (Order No. 30414 p. 11). (5)Idaho Power believes that application of the Cassia Formula in this instance will allow it to successfully defend a comparability claim brought by a Federal Energy Regulatory Commission ("FERC") jurisdictional customer claiming that Idaho Power and the Commission had given unlawful , preferential treatment to QF resources. Idaho Power requests that the Commission process this Motion by modified procedure in accordance with RP201 et seq. CONCLUSION For the reasons cited herein , Idaho Power respectfully submits that the enclosed Generator Interconnection Agreement is consistent with Schedule 72 , Commission Order MOTION - 4 No. 30414 and is in the public interest. The Company hereby requests that the Commission issue its order: (1) processing this case in accordance with RP 201 et seq. modified procedure; and (2) approving the Bennett Creek Generator Interconnection Agreement without change or condition.

Interconnection Requirements for a Wind Generating Plant Technical Standards Applicable to a Wind Generatinq Plant Low Voltaqe Ride-Throuqh (LVRT) Capability A wind generating plant shall be able to remain online during voltage disturbances up to the time periods and associated voltage levels set forth in the standard below. All wind generating plants must meet the following requirements: Wind generating plants are required to remain in-service during three-phase faults with normal clearing (which is a time period of approximately 4 - 9 cycles) and single line to ground faults with delayed clearing, and subsequent post-fault voltage recovery to pre-fault voltage unless clearing the fault effectively disconnects the generator from the system. The clearing time requirement for a three-phase fault will be specific to the wind generating plant substation location, as determined by and documented by the transmission provider. The maximum clearing time the wind generating plant shall be required to withstand for a three-phase fault shall be 9 cycles after which, if the fault remains following the location-specific normal clearing time for three-phase faults, the wind generating plant may disconnect from the transmission system. A wind generating plant shall remain interconnected during such a fault on the transmission system for a voltage level as low as zero volts , as measured at the high voltage side of the wind GSU. This requirement does not apply to faults that would occur between the wind generator terminals and the high side of the GSU. Wind generating plants may be tripped after the fault period if this action is intended as part of a special protection system. Wind generating plants may meet the LVRT requirements of this standard by the performance of the generators or by installing additional equipment (~, Static V Ar Compensator) within the wind generating plant or by a combination of generator performance and additional equipment. Existing individual generator units that are, or have been , interconnected to the network at the same location at the effective date of the Appendix G LVRT Standard are exempt from meeting the Appendix G LVRT Standard for the remaining life of the existing generation equipment. Existing individual generator units that are replaced are required to meet the Appendix G LVRT Standard. Idaho Power Company Generator Interconnection Agreement # 186/187 I.P.C. No. 28. Tariff No.1 01 e 2 of 2 ii.Power Factor Desiqn Criteria (Reactive Power) A wind generating plant shall maintain a power factor within the range of 0.95 leading to 0. lagging, measured at the Point of Interconnection as defined in this agreement, if the Transmission Provider s System Impact Study shows that such a requirement is necessary to ensure safety or reliability. The power factor range standard can be met by using, for example , power electronics designed to supply this level of reactive capability 606 (taking into account any limitations due to voltage level , real power output, etc.) or fixed and switched capacitors if agreed to by the Transmission Provider, or a combination of the two. The Interconnection Customer shall not disable power factor equipment while the wind plant is in operation. Wind plants shall also be able to provide sufficient dynamic voltage support in lieu of the power system stabilizer and automatic voltage regulation at the generator excitation system if the System Impact Study shows this to be required for system safety or reliability. The System Impact Study demonstrates that the Interconnection Customer may safely and reliably interconnect, the Generation Facilities associated with the Company s interconnection requests #186 and 187, with the 138 kV transmission system if such Generation Facilities maintain a power factor between 0.95 leading to 0.95 lagging at the high voltage side of the 138/34.5 kV transformer at the Interconnection Point. The Generation Facilities are to implement power factor control regulation with a unity power factor set point. Idaho Power may direct Interconnection Customer to maintain a set point other than unity as required by transmission system conditions. iii.Supervisory Control and Data Acquisition (SCADA) Capability The wind plant shall provide SCADA capability to transmit data and receive instructions from the Transmission Provider to protect system reliability. The Transmission Provider and the wind plant Interconnection Customer shall determine what SCADA information is essential for the proposed wind plant, taking into account the size of the plant and its characteristics, location, and importance in maintaining generation resource adequacy and transmission system reliability in its area.
