PacifiCorp – 2007 IRPChapter 1 – Executive SummaryRESOURCE OPTIONSThe company developed cost and performance profiles for supply-side resources, demand-sidemanagement programs, transmission expansion projects, and firm market purchases (front officetransactions) for use in portfolio modeling. Each supply-side option also included the estimationand use of capital cost ranges for each supply-side option. These cost ranges reflect cost uncertainty,and their use in this plan acknowledges the significant construction cost increases that areoccurring.PacifiCorp used the Electric Power Research Institute’s Technical Assessment Guide (TAG®),along with recent project experience and consultant studies, to develop its supply-side resourceoptions. The purpose of using TAG data is to rely on consistently-derived cost estimates from awell-respected independent outside source. The TAG database is considered the default sourcefor developing the supply-side resource alternatives used in the 2007 IRP. Values are adjusted asnecessary using information from PacifiCorp or other sources that reflects corporate or locationspecificconsiderations. TAG capital costs for certain technologies were adjusted to be more inline with PacifiCorp’s recent cost studies and project experience. In addition, TAG emissionestimates were adjusted based on permitting expectations in PacifiCorp’s service territory. Theuse of TAG information is new to PacifiCorp’s integrated resource planning process.The company also developed transmission resources to support meeting loads with new generationoptions, to integrate wind, to enhance transfer capability and maintain reliability acrossPacifiCorp’s system, and to boost import/export capability with respect to external markets.These transmission resources were entered as options in PacifiCorp’s capacity expansion optimizationtool, and were thus allowed to compete directly with other resources for inclusion in portfolios.MODELING AND RISK ANALYSIS APPROACHThe IRP modeling effort seeks to determine the comparative cost, risk, supply reliability, andemissions attributes of resource portfolios.PacifiCorp used two modeling tools for portfolio analysis: the Capacity Expansion Module(CEM) and the Planning and Risk (PaR) Module. The CEM performs a deterministic least-costoptimization with resource options over the twenty-year study period. The CEM operates byminimizing for each year the operating costs for existing resources subject to system load balance,reliability and other constraints. Over the study period, it also optimizes resource additionssubject to resource investment and capacity constraints (monthly peak loads plus a planning reservemargin for a 24-zone model topology). The PaR module is a chronological commitment/dispatchproduction cost model that was operated in probabilistic (stochastic) mode to developrisk-adjusted portfolio performance measures.The 2007 IRP modeling effort consisted of resource screening, risk analysis portfolio development,and detailed production cost and stochastic risk analysis. For resource screening, the companyused the CEM to evaluate generation, load control, price-responsive demand-side management,market purchases, and transmission resources on a comparable basis with the use of “alter-5
