Date: May 7, 2015 Title: Review of Electric Utility Integrated Resource Plans

Integrated Resource Plan Overview

Integrated resource plans (IRPs) are a tool that electric utilities use to plan operations and investments over long time horizons. Since much of the infrastructure required in the electric utility industry can take seve ral years to build and lasts for decades
, it is important to develop long

- term plans. These plans typically cover 10 to 20 years a nd are mandated by state public utilit y commissions (PUCs). T o develop these plans
, utilities model demand over a specified time period and evaluate a suite of options for meeting that demand (e.g., demand side manageme nt programs, investment in transmissi on infrastructure or new capacity). Multiple scenarios are typically evaluated that look at variations in fuel prices, demand growth, carbon price and other factors that could impact the system. Additionally, IRPs account for existing environmental regulat ions and the potential for future regulations and, in many cases, provide plans for compliance. These plans are generally updated eve ry two or three years per state law. States vary in the specificity of the content they require. Usually an overview of supply, demand and transmission are required, while some require a particular focus on certain areas such as demand

- side initiatives. Some states provide guidelines for analysis.

EPA conducted a r eview of current IRPs t o infor m the development of the new source performance standard for emi ssions of carbon dioxide for existing affected fossil fuel

- fired electric utility generating units. An overview o f the results is provided below.Summary of IRPs
