As part of the WECC PIP survey, project sp<strong>on</strong>sors were asked to identify the transmissi<strong>on</strong> projects’<br />
primary and sec<strong>on</strong>dary purpose. Stakeholders have asked for a greater understanding as to why<br />
transmissi<strong>on</strong> projects are proposed. As part of the data gathering, it was suggested the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> could not<br />
<strong>on</strong>ly update the transmissi<strong>on</strong> projects, but answer stakeholder questi<strong>on</strong>s related to transmissi<strong>on</strong><br />
development. The intenti<strong>on</strong> of soliciting this informati<strong>on</strong> is to develop a high-level understanding as to<br />
what is driving the industry to expand the transmissi<strong>on</strong> system. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g>, with stakeholder involvement,<br />
identified five primary reas<strong>on</strong>s to develop transmissi<strong>on</strong> projects. Of the 28 CCTA, 26 listed a specific<br />
reas<strong>on</strong> for the projects “primary purpose”. A general summary of this informati<strong>on</strong>, as well as a<br />
descripti<strong>on</strong> of the primary purpose reas<strong>on</strong>s, are presented in the chart below:<br />

Project sp<strong>on</strong>sors supplied their primary and sec<strong>on</strong>dary reas<strong>on</strong>s for transmissi<strong>on</strong> development. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g><br />
did no investigate the veracity of the submissi<strong>on</strong>s. Project sp<strong>on</strong>sor feedback to the WECC PIP questi<strong>on</strong>s<br />
related to the primary and sec<strong>on</strong>dary purpose of the project generally was that many projects meet<br />
several categories and it is often difficult to choose just <strong>on</strong>e purpose for a project.<br />
