The criteria used in the 2022 CCTA selection process are explained in more detail below. Criteria 1: Regional Significance To be included in the CCTA, the projects must meet the following voltage level in order to be of regional significance 6 : 1. projects that are 500 kV and above; or 2. projects at 345 kV unless they are deemed not to be a backbone facility; or 3. projects above 200 kV that are deemed to be backbone facilities. If the project was regionally significant then it moved on for evaluation in Criteria 2. Criteria 2: Construction Status A project that is currently under construction 7 is automatically included on the CCTA list. A project that meets Criteria 1, but not Criteria 2, is further considered in Criteria 3 and Criteria 4. Criteria 3: Financial Indicators The <strong>SCG</strong> used publically available information, provided by project sponsors, in the WECC PIP to assess the development status of projects. The list of fields that project sponsors can respond to for a project is available in Appendix B – Letter to Project Sponsors. The <strong>SCG</strong> distilled this list of questions down to four main financial indicators used to evaluate the project in Criteria 3. 1. Does the project have executed transmission service agreements that commit the project developer to construct the project 2. Does the project have executed participation contracts from credit worthy shippers that commit the project developer to construct the project 3. Is the project included in an IRP 4. Does the project have regulatory approval for cost recovery 8 In order to be considered eligible for inclusion on the CCTA, there must have been at least one affirmative response (“yes”) to one of the preceding financial indicators. Criteria 4: Implementation Status Indicators The <strong>SCG</strong> used publically available information, provided by project sponsors, in the WECC PIP to assess the development status of projects. The list of fields that project sponsors can respond to for a project is available in Appendix B. The <strong>SCG</strong> distilled this list of questions down to a key implementation indicator used to evaluate the project in Criteria 4. What percentage of the required permits have been secured for: 1. Federal 2. State/Provincial 3. Local A project must have started at least one of the three applicable permitting processes to be eligible for inclusion on the CCTA. 6 Projects of lower voltage are modeled by WECC members in the power flow base case assembled and vetted by the Technical Studies Subcommittee. 7 “Under construction” is defined as physically building the facility. 8 Cost recovery is separate from cost allocation and varies depending on the jurisdiction of the project developer.

To summarize, all CCTA eligible projects must pass Criteria 1 (Regional Significance). Projects meeting Criteria 1 that were under construction were included as CCTA projects based on Criteria 2. Those projects not under construction had to pass both Criteria 3 (Financial Indicators) and Criteria 4 (Implementation Status Indicators) in order to be included as CCTA projects. As a final step, all projects on the CCTA list underwent review by the <strong>SCG</strong>, which reserved the right to exclude projects on an individual basis because selecting projects using rigid criteria is neither achievable nor desirable. 2022 CCTA Projects By making use of the CCTA selection process, as introduced above, there are two types of projects that make up the CCTA. 1. Projects that are of regional significance and under construction. 2. Projects that are of regional significance and not under construction but have developmental indicators sufficient to meet the predefined criteria designed to indicate that there is a high probability that the project will be in-service in the 10-year timeframe (i.e., met both Criteria 3 and Criteria 4). The following projects are of regional significance (Criteria 1) and have a high probability of being inservice. 1. Under Construction (Criteria 2) Devers - Colorado River 500 kV (DCR) Transmission Line Project Gateway Central Project – Mona to Oquirrh 500 kV (Energy Gateway Segment C) MATL Midway-Waterton Pawnee-Smoky Hill Pinal Central-Tortolita Pinal West-Pinal Central-Browning (SEV) Sunrise Powerlink SWIP South (Robinson Summit to Harry Allen) Tehachapi Upgrade West of McNary Reinforcement Project Group 1 (McNary - John Day) West of McNary Reinforcement Project Group 2 (Big Eddy - Knight) 2. Not Under Construction, but met CCTA Selection Criteria 3 and 4 Boardman-Hemingway 500 kV (B2H) Cascade Crossing Central Ferry - Lower Monumental (Little Goose Area Reinforcement) Delaney-Palo Verde 500kV Line Gateway Central Project, Sigurd - Red Butte - Crystal 345 kV Line Gateway South Project – Segment #2 (Aeolus-Mona 500 kV) Gateway West Transmission Project Segment 1A – Windstar to Jim Bridger 230 kV, 500 kV October 21, 2011 – Draft for Public Review 8 | P a g e
