<br /> <br />Background <br /> <br />Many related processes and <br />Western policies influence the <br />Rcplacement Rcsources <br />Process in addition to the unavailability of <br />peak generating capability at Glen Canyon <br />power plant. This section describes the <br />key influences on the Replacement <br />Resources Process, including an overview <br />of the SLCNIP and Glen Canyon Dam <br />operations, historical events and prece- <br />dents, a discussion of potential future <br />operational changes, and other relevant <br />policies and pro- <br />cesses, The <br />diagram below <br />illustrates some of <br />these key influences <br />on the Replacement <br />Resources Process. <br /> <br />, <br /> <br />FERC Order <br />888 and 889 <br /> <br />Western and <br />the SLCA <br />Integrated <br />Projects <br /> <br />Principles of <br />Integrated Resource <br />Planning <br /> <br />\. <br /> <br />Western is a <br />power marketing <br />administration \",ithin <br />the U.S, Depart- <br />ment of Energy.
