What is the estimated additional cost per kWh incurred by Idaho Power to provide transmission for these PURPA projects over the ten-year period? RESPONSE TO REQUEST FOR PRODUCTION NO. 15: Responding to this request requires the Company to make several assumptions. First, the Twin Falls cluster has one large generation project which is subject to FERC transmission reimbursement regulations and as a result, this project has been removed for purposes of responding to this production request. Second , the remaining projects in the cluster are PURPA projects and if the Commission accepts the Stipulation, Idaho Power would eventually rate base $4. million for these PURPA projects. The PURPA projects' 25% contribution in aid of construction has already been deducted to determine the $4.9 million amount. Third, utilizing a generation capacity factor of 30% for all projects, the PURPA projects in the cluster are assumed to produce 631 000 MWh annually. Fourth , because the projects are assumed to receive full reimbursement within the first year of operation , no interest is applied to the unpaid balance and the calculation does not consider the effects of depreciation. Based on the above-described assumptions , the estimated transmission cost associated with the incremental $4.9 million investment would be $0.0078 per kWh. It is impossible for Idaho Power to be certain as to when the projects will actually come on-line, or how long it will take to fully reimburse the projects , because ~~~~ reimbursement is based on performance GRd curre the unlmO'.FERC interest rate ~~~~e;'~e ~ri.;'a. The response to this request was prepared by Dave Angell, Manager, Delivery Planning, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney, Idaho Power Company. REQUEST FOR PRODUCTION NO. 16: How does Idaho Power s investment commitment in Network upgrades with redispatch change if only Cassia commits to participate? RESPONSE TO REQUEST FOR PRODUCTION NO. 16: The cost allocation would be similar to that shown in Table B-3, Exhibit B to the Stipulation because the Cassia projects alone will not allow enough dispatch capability to avoid the transmission network improvements associated with the no-dispatch option. This scenario would result in Idaho Power investing about $52 million for the transmission associated with cluster PURPA projects. The response to this request was prepared by Dave Angell , Manager, Delivery Planning, Idaho Power Company, in consultation with Barton L. Kline , Senior Attorney, Idaho Power Company. REQUEST FOR PRODUCTION NO. 17: Under what circumstances would a project developer not receive a full refund of the transmission cost advance at the end of the ten-year refund period? RESPONSE TO REQUEST FOR PRODUCTION NO. 17: Idaho Power can think of two examples of circumstances where the QF project developer would not receive a full refund of the transmission costs advanced at the end of the first ten-year period. First, if a QF project defaults on either the Interconnection Agreement or the Firm Energy Sales Agreement and the default results in either or both contracts being terminated , the project developer would not receive a full refund of the transmission costs advanced. Second , if a QF developer failed to maintain the minimum mechanical availability specified in the Interconnection Agreement, the developer would not receive a transmission refund for that month. This could result in a QF developer receiving less than a full refund over the ten-year period. The response to this request was prepared by Barton L. Kline , Senior Attorney, Idaho Power Company. REQUEST FOR PRODUCTION NO. 18 How will transmission network upgrade costs be allocated (including those borne by Idaho Power) if projects in the queue continue to request firm network interconnection services but do not commit to redispatch? RESPONSE TO REQUEST FOR PRODUCTION NO. 18: If a QF project chooses not to be subject to redispatch , it would be responsible for paying the full cost of the transmission network upgrade required to accommodate its capacity. Those amounts are shown on Table B-3, Exhibit B to the Stipulation. As a condition of interconnection, the project would also be required to post liquid security to cover the full cost of the upgrade until such time as the full network upgrade was completed. The sharing of costs would be the same as for the QFs that choose the redispatch option. The response to this request was prepared by Dave Angell , Manager, Delivery Planning, Idaho Power Company, in consultation with Barton L. Kline, Senior Attorney, Idaho Power Company. -/.h.DATED at Boise, Idaho, this day of July, 2007. BART Attorney for Idaho Power Company CERTIFICATE OF SERVICE ..
