Executive Summary<br />
The Subregi<strong>on</strong>al Planning Group (SPG) Coordinati<strong>on</strong> Group (<str<strong>on</strong>g>SCG</str<strong>on</strong>g>) aids the Regi<strong>on</strong>al Transmissi<strong>on</strong><br />
Expansi<strong>on</strong> Planning (RTEP) process by providing the Transmissi<strong>on</strong> Expansi<strong>on</strong> Planning Policy Committee<br />
(TEPPC) with a list of transmissi<strong>on</strong> projects that have a high probability of being c<strong>on</strong>structed in the 10-<br />
year timeframe. This list of projects serves as a key input assumpti<strong>on</strong> for TEPPC’s 10-year planning<br />
studies. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> assisted in the development of the <strong>Western</strong> Electricity Coordinating Council’s (WECC)<br />
first 10-Year Regi<strong>on</strong>al Transmissi<strong>on</strong> Plan by providing this list in 2010, which was called the Foundati<strong>on</strong>al<br />
Projects List. TEPPC is starting to develop the next 10-year plan that requires an update to the list. This<br />
iterati<strong>on</strong> of the list is called the Comm<strong>on</strong> <strong>Case</strong> Transmissi<strong>on</strong> Assumpti<strong>on</strong>s (CCTA). The purpose, process<br />
and projects in the CCTA are presented in this <str<strong>on</strong>g>report</str<strong>on</strong>g>.<br />
The CCTA is not the WECC 10-Year Regi<strong>on</strong>al Transmissi<strong>on</strong> Plan, nor does it indicate that WECC members<br />
or stakeholders support or endorse any of the transmissi<strong>on</strong> projects in the CCTA. The CCTA is<br />
comparable to other assumpti<strong>on</strong>s required for transmissi<strong>on</strong> planning studies, such as predicti<strong>on</strong>s <strong>on</strong><br />
load growth and generator installati<strong>on</strong>s. It is necessary to identify and include high-probability<br />
transmissi<strong>on</strong> projects when c<strong>on</strong>ducting transmissi<strong>on</strong> planning studies. Planning study results would be<br />
unrealistic if studies included changes in predicted load and generati<strong>on</strong>, but failed to c<strong>on</strong>sider the<br />
inclusi<strong>on</strong> of any high-probability incremental transmissi<strong>on</strong>.<br />
The CCTA projects were selected using a transparent, repeatable, c<strong>on</strong>sistent and well-documented<br />
process. The meetings and webinars where the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> developed the CCTA selecti<strong>on</strong> process were public<br />
and open to all RTEP stakeholders. The process relied up<strong>on</strong> public data and predefined criteria that were<br />
used to guide the selecti<strong>on</strong> of projects for inclusi<strong>on</strong> in the CCTA. Project informati<strong>on</strong>, project<br />
development status indicators, selecti<strong>on</strong> criteria, and any excepti<strong>on</strong>s to the established process are<br />
documented in this <str<strong>on</strong>g>report</str<strong>on</strong>g>.<br />
The WECC Transmissi<strong>on</strong> Project Informati<strong>on</strong> Portal (PIP) c<strong>on</strong>tains publically available project informati<strong>on</strong><br />
for nearly 90 projects currently under development in the <strong>Western</strong> Interc<strong>on</strong>necti<strong>on</strong> (Appendix C – WECC<br />
Project Informati<strong>on</strong> Portal). The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> reviewed all of these projects and several others, as in some<br />
specific cases project sp<strong>on</strong>sors provided informati<strong>on</strong> directly to the <str<strong>on</strong>g>SCG</str<strong>on</strong>g>. The <strong>2022</strong> CCTA selecti<strong>on</strong><br />
process resulted in the inclusi<strong>on</strong> of 28 transmissi<strong>on</strong> projects <strong>on</strong> the list. Of these 28 projects, 12 are<br />
currently under c<strong>on</strong>structi<strong>on</strong>.<br />

Background<br />
Multiple utilities own and operate the transmissi<strong>on</strong> system that makes up the <strong>Western</strong> Interc<strong>on</strong>necti<strong>on</strong>.<br />
Because changes to the system in <strong>on</strong>e area can impact performance and reliability of the transmissi<strong>on</strong><br />
system in another utilities territory, a regi<strong>on</strong>al approach is required when studying the effect of major<br />
additi<strong>on</strong>s or changes. The Subregi<strong>on</strong>al Planning Group (SPG) Coordinati<strong>on</strong> Group (<str<strong>on</strong>g>SCG</str<strong>on</strong>g>) was formed to<br />
assist in coordinating regi<strong>on</strong>al transmissi<strong>on</strong> plans for the <strong>Western</strong> Interc<strong>on</strong>necti<strong>on</strong>.<br />
The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> is an ad-hoc committee as described in<br />
its charter. Any interested party may participate<br />
in <str<strong>on</strong>g>SCG</str<strong>on</strong>g> activities. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> members are listed<br />

The Transmissi<strong>on</strong> Expansi<strong>on</strong> Planning Policy Committee (TEPPC) guides the Regi<strong>on</strong>al Transmissi<strong>on</strong><br />
Expansi<strong>on</strong> Planning (RTEP) process used to create 10- and 20-year regi<strong>on</strong>al transmissi<strong>on</strong> plans. RTEP is<br />
funded, in part, by a grant from the U.S. Department of Energy (DOE). The RTEP process is bottom-up<br />
with informati<strong>on</strong> flowing to TEPPC from stakeholders throughout the <strong>Western</strong> Interc<strong>on</strong>necti<strong>on</strong>. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g><br />
represents a set of these stakeholders and provides TEPPC with transmissi<strong>on</strong> study assumpti<strong>on</strong>s and<br />
technical guidance as necessary.<br />
In 2010, the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> provided key study input to TEPPC by submitting a list of transmissi<strong>on</strong> projects that<br />
were currently under development that would be assumed in-service for the TEPPC 2020 Base <strong>Case</strong>. This<br />
list of projects was known as the “Foundati<strong>on</strong>al Projects List” and the 2020 Base <strong>Case</strong> was the starting<br />
case for all producti<strong>on</strong> cost studies used to inform the 2011 <strong>Western</strong> Electricity Coordinating Council<br />
(WECC) 10-Year Regi<strong>on</strong>al Transmissi<strong>on</strong> Plan. Projects that were sufficiently advanced in<br />
planning/design/permitting or c<strong>on</strong>structi<strong>on</strong> status for the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> to c<strong>on</strong>clude that there was a high-degree<br />

of certainty that they would be completed and operati<strong>on</strong>al by the end of 2020 were included <strong>on</strong> the list.<br />
These projects were submitted to TEPPC and assumed operati<strong>on</strong>al in the 2020 Base <strong>Case</strong>. A sec<strong>on</strong>d list<br />
of projects inclusive of other major transmissi<strong>on</strong> projects that <str<strong>on</strong>g>SCG</str<strong>on</strong>g> members were aware of was also<br />
provided. This sec<strong>on</strong>d list was called the “Potential Projects List.” These projects could be used by TEPPC<br />
to mitigate c<strong>on</strong>gesti<strong>on</strong> identified in their studies.<br />
TEPPC is c<strong>on</strong>structing a <strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong> to be used as the starting point for additi<strong>on</strong>al studies run in<br />
the TEPPC 2011 and 2012 Study Programs. Results from the TEPPC Study Programs will be used to<br />
inform the 2013 WECC 10-Year Regi<strong>on</strong>al Transmissi<strong>on</strong> Plan. The creati<strong>on</strong> of the new <strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong><br />
requires that the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> provide an updated list of projects to TEPPC. This <str<strong>on</strong>g>report</str<strong>on</strong>g> documents the purpose,<br />
process and resultant list of projects submitted to TEPPC for inclusi<strong>on</strong> in the <strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong>. 3<br />
The first <str<strong>on</strong>g>report</str<strong>on</strong>g> published in August 2010 provided a list of “Foundati<strong>on</strong>al” projects and a list of<br />
“Potential” projects used by TEPPC in the analysis for the WECC 10-Year Regi<strong>on</strong>al Transmissi<strong>on</strong> Plan<br />
completed in 2011. By c<strong>on</strong>trast, this <str<strong>on</strong>g>report</str<strong>on</strong>g> provides <strong>on</strong>ly a list of facilities that have a high-degree of<br />
certainty of being in service by <strong>2022</strong>. This list has been renamed to capture the essence of the list as<br />
study input assumpti<strong>on</strong>s, which was requested by stakeholders and is now the “<strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong><br />
Transmissi<strong>on</strong> Assumpti<strong>on</strong>s” or CCTA.<br />
Comm<strong>on</strong> <strong>Case</strong> Transmissi<strong>on</strong> Assumpti<strong>on</strong>s (CCTA)<br />
In resp<strong>on</strong>se to interested stakeholder comments, the <str<strong>on</strong>g>SCG</str<strong>on</strong>g>’s sec<strong>on</strong>d effort to identify transmissi<strong>on</strong><br />
projects that have a high probability of being in service in the approaching 10-year timeframe resulted in<br />
the development of a transparent, repeatable and c<strong>on</strong>sistently applied process. During this robust<br />
process, <str<strong>on</strong>g>SCG</str<strong>on</strong>g> membership sought greater stakeholder input 4 and also turned to the project sp<strong>on</strong>sors to<br />
submit project informati<strong>on</strong> to the WECC Transmissi<strong>on</strong> Project Informati<strong>on</strong> Portal (PIP). In additi<strong>on</strong> to<br />
typical project informati<strong>on</strong> (substati<strong>on</strong> terminati<strong>on</strong>s, voltage, length, in service, etc.), the <str<strong>on</strong>g>SCG</str<strong>on</strong>g><br />
coordinated with WECC to include WECC PIP questi<strong>on</strong>s 5 designed to help determine if a project was<br />
sufficiently far enough al<strong>on</strong>g the developmental timeline to be c<strong>on</strong>sidered in service by <strong>2022</strong>. Of the 89<br />
requests sent, 71 resp<strong>on</strong>ses were received prior to publishing this <str<strong>on</strong>g>report</str<strong>on</strong>g>.<br />
Purpose of CCTA<br />
Electric transmissi<strong>on</strong> infrastructure, loads and generati<strong>on</strong> resources must be accurately represented<br />
when c<strong>on</strong>ducting transmissi<strong>on</strong> planning studies. Generati<strong>on</strong>, load and transmissi<strong>on</strong> change over time<br />
and TEPPC has a set of established tools, processes and resources to help estimate these changes. The<br />
<str<strong>on</strong>g>SCG</str<strong>on</strong>g> provides TEPPC with a list of regi<strong>on</strong>ally significant transmissi<strong>on</strong> projects that have a high probability<br />
of being built in the next 10 years. The CCTA relati<strong>on</strong> to other WECC 10-year plan inputs is shown in the<br />
next diagram:<br />
3 TEPPC creates 10-year plans bi-annually. TEPPC c<strong>on</strong>ducts analytics annually through a study program. It is these<br />
study programs that are used to inform and support the 10-year plans.<br />
4 Stakeholder outreach is documented in Appendix A – Outreach Activities.<br />
5 Stakeholders, such as the State-Provincial Steering Committee under the <strong>Western</strong> Governors’ Associati<strong>on</strong>,<br />
requested additi<strong>on</strong>al project informati<strong>on</strong> <strong>on</strong> projects that were not used for determining certainty of in-service.<br />

Analysis<br />
If TEPPC and the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> did not include “high-probability” projects in future planning studies, results would<br />
be skewed. Generati<strong>on</strong> and load levels typically increase due to populati<strong>on</strong> and ec<strong>on</strong>omic growth. By<br />
failing to include high-probability incremental transmissi<strong>on</strong>, study results would <str<strong>on</strong>g>report</str<strong>on</strong>g> unrealistic<br />
amounts of c<strong>on</strong>gesti<strong>on</strong>. Including all potential transmissi<strong>on</strong> projects has the opposite, yet still<br />
undesirable, effect. By including a set of high-probability incremental transmissi<strong>on</strong> projects, al<strong>on</strong>g with<br />
predicti<strong>on</strong>s <strong>on</strong> changes in load and generati<strong>on</strong>, a more accurate representati<strong>on</strong> of the future <strong>Western</strong><br />
Interc<strong>on</strong>necti<strong>on</strong> is achieved in TEPPC 10-year studies.<br />
TEPPC can add transmissi<strong>on</strong> facilities to mitigate c<strong>on</strong>gesti<strong>on</strong> and integrate new resources as necessary.<br />
The inclusi<strong>on</strong> of a particular project in the CCTA does not preclude TEPPC from removing the project<br />
from its transmissi<strong>on</strong> studies. Furthermore, the CCTA does not replace or impose changes <strong>on</strong> individual<br />
SPG transmissi<strong>on</strong> planning processes and plans.<br />
CCTA Selecti<strong>on</strong> Strategy<br />
Deciding what specific projects should be assumed as in-service in planning studies is not a trivial task.<br />
There are numerous approaches that could be employed. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> discussed three selecti<strong>on</strong> strategies<br />
that could be used to fulfill the goal of selecting projects with a high probability of being c<strong>on</strong>structed in<br />
the next 10 years. The first two techniques provide bookends for reas<strong>on</strong>able approaches while the third<br />
is the strategy employed by the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> in developing the <strong>2022</strong> CCTA.<br />
1) Fully Inclusive - Include all known transmissi<strong>on</strong> projects in development and under<br />
c<strong>on</strong>structi<strong>on</strong>. This method would likely overestimate how much transmissi<strong>on</strong> will actually be<br />
c<strong>on</strong>structed in the next 10 years as it is comm<strong>on</strong>ly understood that not all proposed<br />
transmissi<strong>on</strong> projects are actually c<strong>on</strong>structed. Permitting difficulties and financial<br />
shortcomings are just two examples of issues that cause proposed projects to be cancelled<br />
or delayed.<br />
October 21, 2011 – Draft for Public Review<br />
3 | P a g e
2) C<strong>on</strong>structi<strong>on</strong> Only - Include <strong>on</strong>ly those projects under c<strong>on</strong>structi<strong>on</strong>. It is well understood<br />
that projects that are under c<strong>on</strong>structi<strong>on</strong> have a high probability of being completed and put<br />
into service. However, this strategy would likely underestimate transmissi<strong>on</strong> additi<strong>on</strong>s in the<br />
10-year timeframe. A set of projects that are moving through the developmental process<br />
will enter the c<strong>on</strong>structi<strong>on</strong> phase so<strong>on</strong>. These projects would be excluded using this<br />
selecti<strong>on</strong> strategy and as a c<strong>on</strong>sequence, future transmissi<strong>on</strong> infrastructure would be<br />
underestimated.<br />
3) C<strong>on</strong>structi<strong>on</strong> and Partially Inclusive - Include projects under c<strong>on</strong>structi<strong>on</strong> and a set of<br />
projects that meet predefined criteria designed to indicate that there is a high probability<br />
that the project will be in service in the 10-year timeframe. This strategy represents the<br />
“middle ground” of the previous two opti<strong>on</strong>s. From the <str<strong>on</strong>g>SCG</str<strong>on</strong>g>’s perspective, this strategy<br />
provides the most appropriate starting point for TEPPC 10-year studies.<br />
Development of the <strong>2022</strong> CCTA<br />
Similar to predicti<strong>on</strong>s <strong>on</strong> load growth and generator installati<strong>on</strong>s, the CCTA is <strong>on</strong>e of many assumpti<strong>on</strong>s<br />
used as input into TEPPC planning studies. The CCTA is not the plan, nor does it indicate that WECC<br />
members or stakeholders support or endorse any of the transmissi<strong>on</strong> projects in the CCTA. The<br />
following secti<strong>on</strong> is a descripti<strong>on</strong> of how the <strong>2022</strong> CCTA projects were selected.<br />
The CCTA Process<br />
Development of the <strong>2022</strong> CCTA process used project sp<strong>on</strong>sor supplied informati<strong>on</strong>, as submitted to the<br />
WECC PIP. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> attempted to make the CCTA process highly transparent, repeatable and publically<br />
available. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> realized that specific project informati<strong>on</strong> was not <strong>on</strong>ly important to the CCTA process<br />
but for other planning processes and policy. The projects and project sp<strong>on</strong>sors were identified by two<br />
main methods: SPG 10-year plans or previous entry into the WECC PIP. Once project sp<strong>on</strong>sors updated<br />
their project informati<strong>on</strong> in the WECC PIP, the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> reviewed the informati<strong>on</strong> and assessed the regi<strong>on</strong>al<br />
significance and development status of each project using a number of indicators. There were several<br />
benefits to using the WECC PIP, including publicly available informati<strong>on</strong>, the informati<strong>on</strong> is stored in <strong>on</strong>e<br />
locati<strong>on</strong>, and the informati<strong>on</strong> can be logically filtered and sorted based <strong>on</strong> established criteria. The last<br />
benefit allowed the CCTA process to be repeatable. All of these benefits were also requested by<br />
interested stakeholders throughout the process.<br />

Project development indicators were used by the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> as a guide for selecting the <strong>2022</strong> CCTA.<br />
Predetermined criteria were established and each project was evaluated against the criteria using a<br />
c<strong>on</strong>sistent set of development indicators. It is recognized that strict and rigid criteria for determining<br />
what projects should be <strong>on</strong> the CCTA are neither achievable nor desirable. As such, there were some<br />
instances where excepti<strong>on</strong>s were made and projects that met the original development criteria were<br />
excluded from the <strong>2022</strong> CCTA. The reas<strong>on</strong>ing behind these excepti<strong>on</strong>s is documented in this <str<strong>on</strong>g>report</str<strong>on</strong>g>.<br />
Furthermore, as the informati<strong>on</strong> was provided by project sp<strong>on</strong>sors, <strong>on</strong>ly minimal effort was made to<br />
verify the veracity of the submissi<strong>on</strong>. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> did, however, c<strong>on</strong>tact project sp<strong>on</strong>sors where obvious<br />
inc<strong>on</strong>sistencies arose (such as “under c<strong>on</strong>structi<strong>on</strong>” was identified but c<strong>on</strong>flicted with “permitting not<br />
started”) in order to clarify resp<strong>on</strong>ses. In additi<strong>on</strong>, where the WECC PIP had not been updated for known<br />
projects, the sp<strong>on</strong>sors were c<strong>on</strong>tacted to obtain the necessary informati<strong>on</strong>.<br />

Projects in the WECC PIP, or those submitted for <str<strong>on</strong>g>SCG</str<strong>on</strong>g> c<strong>on</strong>siderati<strong>on</strong>, were evaluated for inclusi<strong>on</strong> in the<br />
<strong>2022</strong> CCTA using the following process and criteria.<br />
October 21, 2011 – Draft for Public Review<br />
6 | P a g e
The criteria used in the <strong>2022</strong> CCTA selecti<strong>on</strong> process are explained in more detail below.<br />
Criteria 1: Regi<strong>on</strong>al Significance<br />
To be included in the CCTA, the projects must meet the following voltage level in order to be of regi<strong>on</strong>al<br />
significance 6 :<br />
1. projects that are 500 kV and above; or<br />
2. projects at 345 kV unless they are deemed not to be a backb<strong>on</strong>e facility; or<br />
3. projects above 200 kV that are deemed to be backb<strong>on</strong>e facilities.<br />
If the project was regi<strong>on</strong>ally significant then it moved <strong>on</strong> for evaluati<strong>on</strong> in Criteria 2.<br />
Criteria 2: C<strong>on</strong>structi<strong>on</strong> Status<br />
A project that is currently under c<strong>on</strong>structi<strong>on</strong> 7 is automatically included <strong>on</strong> the CCTA list. A project that<br />
meets Criteria 1, but not Criteria 2, is further c<strong>on</strong>sidered in Criteria 3 and Criteria 4.<br />
Criteria 3: Financial Indicators<br />
The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> used publically available informati<strong>on</strong>, provided by project sp<strong>on</strong>sors, in the WECC PIP to assess<br />
the development status of projects. The list of fields that project sp<strong>on</strong>sors can resp<strong>on</strong>d to for a project is<br />
available in Appendix B – Letter to Project Sp<strong>on</strong>sors. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> distilled this list of questi<strong>on</strong>s down to four<br />
main financial indicators used to evaluate the project in Criteria 3.<br />
1. Does the project have executed transmissi<strong>on</strong> service agreements that commit the project<br />
developer to c<strong>on</strong>struct the project<br />
2. Does the project have executed participati<strong>on</strong> c<strong>on</strong>tracts from credit worthy shippers that commit<br />
the project developer to c<strong>on</strong>struct the project<br />
3. Is the project included in an IRP<br />
4. Does the project have regulatory approval for cost recovery 8<br />
In order to be c<strong>on</strong>sidered eligible for inclusi<strong>on</strong> <strong>on</strong> the CCTA, there must have been at least <strong>on</strong>e<br />
affirmative resp<strong>on</strong>se (“yes”) to <strong>on</strong>e of the preceding financial indicators.<br />
Criteria 4: Implementati<strong>on</strong> Status Indicators<br />
The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> used publically available informati<strong>on</strong>, provided by project sp<strong>on</strong>sors, in the WECC PIP to assess<br />
the development status of projects. The list of fields that project sp<strong>on</strong>sors can resp<strong>on</strong>d to for a project is<br />
available in Appendix B. The <str<strong>on</strong>g>SCG</str<strong>on</strong>g> distilled this list of questi<strong>on</strong>s down to a key implementati<strong>on</strong> indicator<br />
used to evaluate the project in Criteria 4.<br />
What percentage of the required permits have been secured for:<br />
1. Federal<br />
2. State/Provincial<br />
3. Local<br />
A project must have started at least <strong>on</strong>e of the three applicable permitting processes to be eligible for<br />
inclusi<strong>on</strong> <strong>on</strong> the CCTA.<br />
6 Projects of lower voltage are modeled by WECC members in the power flow base case assembled and vetted by<br />
the Technical Studies Subcommittee.<br />
7 “Under c<strong>on</strong>structi<strong>on</strong>” is defined as physically building the facility.<br />
8 Cost recovery is separate from cost allocati<strong>on</strong> and varies depending <strong>on</strong> the jurisdicti<strong>on</strong> of the project developer.<br />
October 21, 2011 – Draft for Public Review<br />
7 | P a g e
To summarize, all CCTA eligible projects must pass Criteria 1 (Regi<strong>on</strong>al Significance). Projects meeting<br />
Criteria 1 that were under c<strong>on</strong>structi<strong>on</strong> were included as CCTA projects based <strong>on</strong> Criteria 2. Those<br />
projects not under c<strong>on</strong>structi<strong>on</strong> had to pass both Criteria 3 (Financial Indicators) and Criteria 4<br />
(Implementati<strong>on</strong> Status Indicators) in order to be included as CCTA projects. As a final step, all projects<br />
<strong>on</strong> the CCTA list underwent review by the <str<strong>on</strong>g>SCG</str<strong>on</strong>g>, which reserved the right to exclude projects <strong>on</strong> an<br />
individual basis because selecting projects using rigid criteria is neither achievable nor desirable.<br />
<strong>2022</strong> CCTA Projects<br />
By making use of the CCTA selecti<strong>on</strong> process, as introduced above, there are two types of projects that<br />
make up the CCTA.<br />
1. Projects that are of regi<strong>on</strong>al significance and under c<strong>on</strong>structi<strong>on</strong>.<br />
2. Projects that are of regi<strong>on</strong>al significance and not under c<strong>on</strong>structi<strong>on</strong> but have developmental<br />
indicators sufficient to meet the predefined criteria designed to indicate that there is a high<br />
probability that the project will be in-service in the 10-year timeframe (i.e., met both Criteria 3<br />
and Criteria 4).<br />
The following projects are of regi<strong>on</strong>al significance (Criteria 1) and have a high probability of being inservice.<br />

CCTA Process Excepti<strong>on</strong>s<br />
All CCTA projects were selected based <strong>on</strong> a c<strong>on</strong>sistent process as described in “CCTA Selecti<strong>on</strong> Process.”<br />
There were several projects that appeared to meet the initial screening criteria based <strong>on</strong> resp<strong>on</strong>ses<br />
included in the WECC PIP, but were excluded from the CCTA list based <strong>on</strong> follow-up discussi<strong>on</strong> with the<br />
project sp<strong>on</strong>sor or further review of the informati<strong>on</strong> submitted to the WECC PIP. These projects and the<br />
associated reas<strong>on</strong>s for being excluded as viewed by the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> are listed in the following table.<br />

Categorizati<strong>on</strong> of Projects<br />
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 />

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 />

Appendix B – Letter to Project Sp<strong>on</strong>sors<br />
Below is the original letter and reminder notice sent to project sp<strong>on</strong>sors to update the WECC PIP.<br />
Original Letter<br />
July 11, 2011<br />
TO: Transmissi<strong>on</strong> Project Sp<strong>on</strong>sors<br />
RE: TEPPC request for additi<strong>on</strong>al transmissi<strong>on</strong> project informati<strong>on</strong><br />
The WECC Regi<strong>on</strong>al Transmissi<strong>on</strong> Expansi<strong>on</strong> Planning (RTEP) process, led by WECC’s Transmissi<strong>on</strong><br />
Expansi<strong>on</strong> Planning Policy Committee (TEPPC), recently began its next planning cycle which will produce<br />
10- and 20-year regi<strong>on</strong>al transmissi<strong>on</strong> plans in 2013. One of the initial activities of the planning cycle is<br />
to create a set of starting point assumpti<strong>on</strong>s for load, generati<strong>on</strong>, and transmissi<strong>on</strong> – the RTEP <strong>2022</strong><br />
Comm<strong>on</strong> <strong>Case</strong>. WECC is reaching out to transmissi<strong>on</strong> project sp<strong>on</strong>sors and others to ensure complete<br />
and accurate informati<strong>on</strong> is available for this planning cycle.<br />
You are receiving this letter because your project was identified by the Subregi<strong>on</strong>al Planning Group<br />
Coordinati<strong>on</strong> Group (<str<strong>on</strong>g>SCG</str<strong>on</strong>g>) as being of regi<strong>on</strong>al significance (i.e., voltage, length) based <strong>on</strong> informati<strong>on</strong> in<br />
the WECC Transmissi<strong>on</strong> Project Informati<strong>on</strong> Portal (Portal). In lieu of a separate questi<strong>on</strong>naire, the<br />
Portal has been expanded to include additi<strong>on</strong>al questi<strong>on</strong>s. Your resp<strong>on</strong>ses will allow the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> to assist<br />
TEPPC in determining if your project will be included in the RTEP <strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong> as a base input<br />
assumpti<strong>on</strong> (assumed in-service in <strong>2022</strong>) and to better understand how to include your project in<br />
various RTEP study cases.<br />
Please follow this link to the Portal and resp<strong>on</strong>d to the questi<strong>on</strong>s for your project. The added or<br />
modified Portal questi<strong>on</strong>s are listed for your reference <strong>on</strong> the next page. Additi<strong>on</strong>ally, in order to model<br />
your project in the <strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong>, or any other RTEP studies, you must email your project EPC file<br />
(based <strong>on</strong> the 2020 HS1 case) to Keegan Moyer (kmoyer@wecc.biz). Project Portal resp<strong>on</strong>ses and EPC<br />
file submittals are due JULY 29, 2011. The informati<strong>on</strong> c<strong>on</strong>tained in the Portal as of this date will be<br />
forwarded to the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> and used for the remainder of the TEPPC 2011 Study Cycle. Developers will not be<br />
asked to update the Portal again until January 2012.<br />
If you have specific questi<strong>on</strong>s about the purpose of the new questi<strong>on</strong>s, or would like help in<br />
understanding the intent of a specific questi<strong>on</strong> and how it might apply to your project, please c<strong>on</strong>tact<br />
me or Keegan Moyer. Also, c<strong>on</strong>tact Keegan if you have any issues accessing your project(s) <strong>on</strong> the Portal.<br />
Lastly, the <str<strong>on</strong>g>SCG</str<strong>on</strong>g> is hosting an informati<strong>on</strong>al webinar <strong>on</strong> Wednesday, July 13, 2011 to discuss the process<br />
used to select projects for the RTEP <strong>2022</strong> Comm<strong>on</strong> <strong>Case</strong>. The discussi<strong>on</strong> will cover the Portal’s expanded<br />
questi<strong>on</strong>s and progress <strong>on</strong> creating criteria to determine project development status. The webinar, open<br />
to all, is specifically geared toward project developers.<br />
We appreciate your time and thank you in advance for your prompt resp<strong>on</strong>se.<br />
Best regards,<br />

Projects not included in the CCTA that were <strong>on</strong> the Foundati<strong>on</strong>al List<br />
The following projects, due to the use of different criteria were not included <strong>on</strong> the CCTA or because<br />
insufficient data was <strong>on</strong> the portal to make an assessment of the project:<br />
All AESO projects – Pending c<strong>on</strong>firmati<strong>on</strong> from AESO<br />
Archer Interc<strong>on</strong>necti<strong>on</strong> – Project development status not provided<br />
The following projects were not included <strong>on</strong> the CCTA as the resource additi<strong>on</strong>s necessary to drive these<br />
projects were not committed additi<strong>on</strong>s. If TEPPC were to model these resource additi<strong>on</strong>s then these<br />
projects should be added to the simulati<strong>on</strong>s.<br />
