# Integrated Resource Plan

Overview The integrated resource plan (IRP) is a comprehensi ve decision support tool and road map for meeting t he company's objective of providing reliable and le ast-cost electric service to all of our customers while addressing th e substantial risks and uncertainties inherent in t he electric utility business. The IRP is developed with considerable public involvement from state utility commission staff, state agencies , customer and industry advocacy groups, project de velopers, and other stakeholders. The key elements of the IRP include: a finding of resource need, focusing o n the first 10 years of a 20-year planning period; the preferred portfolio of supply-side and demand-s ide resources to meet this need; and an action plan that identifies the s teps we will take during the next two to four yearsto implement the plan. PacifiCorp prepares its integrated resource plan on a biennial schedule, filing its plan with state ut ility commissions during each odd numbered year. Fo r five of its six state jurisdictions, the Company receives a formal notifi cation as to whether the IRP meets the commissions’IRP standards and guidelines, referred to as IRP a cknowledgement. For even-numbered years, the Company updates its prefer red resource portfolio and action plan by consideri ng the most recent resource cost, load forecast, re gulatory, and market information. The IRP uses system modeling tools as part of its a nalytical framework to determine the long-run econo mic and operational performance of alternative reso urce portfolios. These models simulate the integration of new resource alt ernatives with our existing assets, thereby informi ng the selection of a preferred portfolio judged to be the most costeffective resource mix after considering risk, supp ly reliability, uncertainty, and government energy resource policies. The IRP report consists of two volumes. Volume 1 isthe company's resource plan, which describes the p lanning environment, a finding of resource need, th e resource portfolio modeling process and assumptions, the preferred res ource portfolio, and the action plan. Volume 2 cons ists of appendices that provide detailed modeling a nd study results, as well as additional planning and IRP regulatory comp liance information.
