PacifiCorp 2007 Integrated Resource Plan (May 30, 2007)

PacifiCorp – 2007 IRPChapter 8 – Action Planas the means to acquire the majority of the 250 average megawatts of Class 2 demand-side resourcesidentified in the 2007 integrated resource plan. The company will continue these programsas long as they are cost-effective, and will seek to add new cost-effective programs in orderto meet this target. The company will also continue to pursue an additional 200 averagemegawatts of energy efficiency measures if cost-effective.With regard to load control (Class 1 demand-side resources), the company is actively working toretain the existing customers and continue expanding participation in these programs to achieveand build upon the 150 megawatts currently identified in the 2007 plan as an existing resource.The company will pursue acquisition of an additional 100 megawatts of load control identified inthe preferred portfolio starting in 2010.The company plans to leverage voluntary load control programs (Class 3 demand-side resources)such as demand buyback, hourly pricing and seasonal pricing, as well as system messaging andeducation (Class 4 demand-side resources), to improve system reliability during peak load hours.Finally, the company will be completing a demand-side management potential study in June2007, which will provide updated information on the potential for acquiring cost-effective demand-sideresources across all major resource types (load management, energy efficiency, demandresponse and system messaging and education). Information learned from the demand-sidemanagement potential study will be incorporated in the company’s demand-side managementprograms and in future integrated resource plans.Combined Heat and PowerThe 2007 integrated resource plan includes 100 megawatts of new combined heat and power in2012. Combined heat and power facilities are allowed to bid into the company’s current east sidebase load request for proposal, and can become part of the company’s resource portfolio as qualifyingfacilities under the Public Utilities Regulatory Policy Act. Additional information on thepotential for combined heat and power will be available from the demand-side management potentialstudy and will be incorporated into the company’s future integrated resource plans.Distributed GenerationThe company investigated the potential of adding distributed generation on the east side of itssystem and was informed by the Utah Department of Air Quality that it was not feasible to relyon existing standby generators at customer sites due to air quality considerations. On the westside of the system, the company found using sensitivity analysis that replacing a new resourcewith combined heat and power and aggregated dispatchable customer-owned standby generatorsmarginally increased cost and risk. The company will have additional information on distributedgeneration potential as part of the demand-side management potential study. Based on this information,the company will determine what further steps to take with regard to distributed generation.Thermal Base Load/Intermediate Load ResourcesThe company has an outstanding request for proposals that is aimed at acquiring up to 1,700megawatts of cost-effective base load resource by 2014 on the east side of its system. The 2007integrated resource plan identifies 1,450 megawatts of base load / intermediate load thermal re-230
