Integrated Resource Plan

PacifiCorp's 2021 Integrated Resource Plan (IRP) builds upon our significant progress toward the goals laid out in the 2017 and 2019 IRPs and identifies investments in modernized transmission, renewable energy, storage, demand response and advanced nuclear resources.

Developed with comprehensive data analysis and stakeholder input, the plan results in a 74% reduction of greenhouse gas emissions from 2005 levels by 2030. 

Clean, reliable, resilient: The power and promise of a connected West

Overview

The IRP is a comprehensive decision support tool and roadmap for meeting the company's objective of providing reliable and least-cost electric service to all of our customers. The plan is developed with considerable public involvement from state utility commission staff, state agencies, customer and industry advocacy groups, project developers, and other stakeholders. 

The key elements of the IRP include: a finding of resource need, focusing on the first 10 years of a 20-year planning period; the preferred portfolio of supply-side and demand-side resources to meet this need; and an action plan that identifies the steps we will take during the next two to four years to implement the plan.

PacifiCorp prepares its integrated resource plan on a biennial schedule, filing its plan with state utility commissions during each odd numbered year. For five of its six state jurisdictions, the company receives a formal notification as to whether the IRP meets the commissions’ IRP standards and guidelines, referred to as IRP acknowledgement. For even-numbered years, the company updates its preferred resource portfolio and action plan by considering the most recent resource cost, load forecast, regulatory, and market information.

The IRP uses system modeling tools as part of its analytical framework to determine the long-run economic and operational performance of alternative resource portfolios. These models simulate the integration of new resource alternatives with our existing assets, thereby informing the selection of a preferred portfolio judged to be the most cost-effective resource mix after considering risk, supply reliability, uncertainty, and government energy resource policies.
