Public Service Company of Colorado Northern Colorado Area Plan Ault to Cloverly Transmission Project This page intentionally left blank APPENDIX C .. } Vii✓.: New Substations To accommodate the substation components, two new substations will be needed: • Husky Substation - In November 2018, a site plan for the new Husky Substation in theTown of Ault was submitted and was approved in February 2018. • East -area substation - approximately 10 acres would be graded and fenced for the new substation; a site will be identified through the planning process. Substations will contain an equipment enclosure, transformer, capacitor bank, and switches to support the distribution feeders. Typically, dead-end structures and static masts are approximately 55 to 62 feet tall. Typical busses are approximately 35 feet tall and electrical equipment enclosures are generally no taller than 15 feet. Grading and landscaping amenities can require additional area, typically increasing the substation site size. Design details will be determined through future engineering efforts.The total site size depends on the existing topography and visual screening opportunities. Xcel Energy Integrating Public Input in Planning Process Alternative sites for the substations and alternative routes for the transmission line have not yet been identified. Xcel Energy conducted a siting study previously in this area and filed a permit application with Weld County to determine approval and final routes for the transmission line in August 2018. However, based on comments received in June 2019 during the County Commission hearing, the company requested to withdraw its permit application. Subsequently, Xcel Energy evaluated the approach of the previous siting study and resolved to begin again with a fresh approach that allows for additional public outreach and engagement. Xcel Energy is committed to work with the community to develop a viable solution to meet growing and changing energy needs in this area.

Cal Environmental Sensitivity and Constraint Levels Nate: Sensitivity depends on tree screening, view orientation, presence of existing transmission facilities, and right-of-way clearing. Identification of environmental constraints will be based on an analysis of the sensitivity of each resource from the introduction of a transmission line or a substation site. Sensitivity is defined as the measure of probable adverse response of each resource to potential direct or indirect effects associated with construction, operation, and maintenance of a transmission line or a substation site. Criteria used to make determinations of environmental sensitivity include the following: • RESOURCE VALUE: A measure of rarity, high intrinsic worth, singularity, or diversity of a resource within the area. • PROTECTIVE STATUS: A measure of the formal concern expressed for a resource either through legal protection or by assignment of special status designation. • PRESENT AND FUTURE USE: A measure of the level of conflict based on land -management policies and/or use and may include issues of specific concern to the agencies and public. Considering the criteria described above, the environmental data will be evaluated and assigned a sensitivity level of low, moderate, high, and exclusion as defined below.The lower the sensitivity of a resource, the more compatible it would be for siting a transmission line and substation in a given area. • EXCLUSION: Areas where legal status would prohibit, or most likely prohibit. the location of transmission or substation facilities. Locations of exclusion areas are considered to be undesirable for location of a transmission line or substation. • HIGH SENSmVITY: Areas determined to be less suitable because of unique, highly valued, complex, historic, or protected resources and significant potential conflict with use, or areas posing substantial hazards to construction and operation of the transmission line and substations. Locations of high sensitivity are considered to be high constraint or least desirable for location of a transmission line or substation. o MODERATE -HIGH SENSITIVITY • MODERATE SENSITIVITY: Areas of potential environmental effects on important or valued resources, resources assigned special status, or some conflict with use. Locations of moderate sensitivity are considered to be moderate constraint areas and less desirable for siting a transmission line or substation. . LOW -MODERATE SENsmvnY ■ LOW SENSITIVITY: Areas where resource conflicts identified through the feasibility study process are minimal These areas of low sensitivity are considered to be of minimal constraint, or high opportunity, for locating a tranamission linear substation, particularly in association with existing transmission line corridors. Opportunity Area Locations where there are opportunities for the introduction of a transmission line and/or a substation. Siting opportunities generally include areas of low sensitivity and locations in proximity to. or including, existing or planned linear facilities and corridors that have been disturbed previously or designated for future use as utility corridors or industrial uso(sl. Typically, such opportunities include existing transmission line (44 kV and greater), major transportation corridors (county roads and state highwaysl, pipeline corridors, and railroads that potentially allow for parallel linear facilities.

Substations will contain an equipment enclosure, transformer, capacitor bank, and switches to support the distribution feeders. Typically, dead-end structures and static masts are approximately 55 to 62 feet tall. Typical busses are approximately 35 feet tall and electrical equipment enclosures are generally no taller than 15 feet. Grading and landscaping amenities can require additional area, typically increasing the substation site size. Design details will be determined through future engineering efforts.The total site size depends on the existing topography and visual screening opportunities.

Xcel Energy conducted a siting study previously in this arE application with Weld County to determine approval and fi transmission line in August 2018. However, based on comments received in June 2019 durin Commission hearing, the company requested to withdraw .a and filed a permit nal routes for the g the County its permit application. Subsequently, Xcel Energy evaluated the approach of the previous siting study and resolved to begin again with a fresh approach that allows for additional public outreach and engagement. Xcel Energy is committed to work with the community to develop a viable solution to meet growing and changing energy needs in this area. Xcel Energy® Public Outreach and Engagement Recognizing the importance of public outreach and engagement, Xcel Energy is increasing its efforts on this project to involve public in the siting and routing process through various means. • Community Working Group A group of local citizens representing diverse backgrounds has been formed to represent the community.This group will work with the Xcel Energy team on the siting and routing study.Two meetings have been conducted (November 2019 and January 2020) and two more will be conducted (March and April 2020).These meetings, as well as the public open houses, coincide with milestones of the study.

SUMMARY: Xcel Energy 6985 UNION PARK CENTER SUITE 600 COTTONWOOD HEIGHTS. UT 84047 USA (NONE 385-218-6346 MEETING MINUTES Transmission Luke Birkholtz Brad Connor Gilbert Flores Hollie Velasquez Horvath Nicole Korbe Nichole Miller Lucas McConnell Betty Mirzayi Brian Oldfield Rita Ruderman Carly Rowe Keith Therence Jonathan Urrutia Bryan Blakely (Turn Corps) Sara O'Keefe (Turn Corps) CO POWER Engineers Mike Doyle Charles Hutchinson Amanda O'Connor Cindy Smith Tad Stout Tad Stout Hollie Velasquez Horvath, Xcel Energy, welcomed the Community Working Group (CWG) members and thanked them for their time and participation. She gave a brief background of the Ault to Cloverly Transmission Project (Project): • When proposing a high -voltage transmission line project, investor -owned utilities such as Xcel Energy must file an application with the Colorado Public Utilities Commission (CPUC) for a Certificate of Public Convenience and Necessity (or CPCN). The CPCN process allows the Company to proceed with implementation, but does not decide the specific routes and locations of the transmission lines and substations or the permitting process. These issues are determined through a separate local government siting process. • The Commission approved the Company's CPCN application for the Northern Colorado Area Plan on March 1, 2018. • In August 2018, Xcel Energy's Colorado (Xcel Energy) filed a permit application (known as a "1041 permit") with Weld County to determine approval and final route of the proposed transmission lines. PAGE 1 OF 4 MEETING MINUTES Xcel Energy presented before the Weld County Planning Commission at a hearing in June 2019 In July 2019, the company requested to withdraw the permit application This decision was made based on public comment received since filing the permit application and on public comment during the Planning Commission hearing in June 2019 Ms Horvath said Xcel Energy withdrew the 1041 permit application to allow the use of a different process to identify the most appropriate site for the new Eaton -area substation and route for the transmission line She stressed that Xcel Energy believes working with the Community Working Group (CWG) as well as other community members and landowners in the Project study area will provide the balance needed between meeting the objectives of the Project (i e , to develop an acceptable solution to meet current and future energy needs in the area) Ms Horvath said the Project is one important step in Xcel Energy's comprehensive plan to upgrade the region's infrastructure and modernize the transmission system She noted that creating a `redundant' system to increase system reliability in this portion of their service area is inherent in the comprehensive plan In addition to the new Xcel Energy Project team members, the company has retained a consulting team from POWER Engineers who has several years of experience facilitating collaborative planning solutions on similar transmission line and substation siting projects to help work with the CWG and the public Introductions of all meeting attendees around the room were then conducted, with name and affiliation noted for each person Cindy Smith, POWER Engineers, reviewed the purpose of CWG (see attached CWG presentation, slide 3) and CWG representation (slide 4) She stressed that the CWG members are an important link between Xcel Energy and the communities She encouraged the CWG members to communicate any comments or questions about the project or process from their neighbors or friends to the Xcel Energy team Ms Smith then reviewed the roles and responsibilities of the CWG, Xcel Energy, and POWER Engineers in the siting and routing process, and reviewed the many factors that have to be considered by Xcel Energy when making decisions about routing and siting (slides 5-10) Mike Doyle, POWER Engineers, introduced the next topic, which addressed electricity basics, from generation to the customers Gilbert Flores, Xcel Energy, provided a big picture overview of the transmission and distribution system (slide 11) Mr Doyle reviewed the three levels of voltage that provide bulk resources to the region (slides 12 and 13) He pointed out that the remnant 44 -kilovolt (kV) system in the study area, which served the area well for a long time, is no longer sufficient due to increasing population growth and electrical loads and needs to be replaced Mr Doyle explained substations need to be spaced every few miles based on load He reviewed examples of substation placement in rural, suburban, and urban areas that showed that more stations are needed in more developed/populated areas (slide 14) Betty Mirzayi, Xcel Energy, reviewed the planning process for electric systems (slide 15) She explained that utilities are required by state statute and federal law to conduct and report short-term and long-term planning to ensure the system is reliable, economic, and meets the needs of customers Part of this planning is forecasting the load that will consume the electric power (e g, identifying transmission needs based on population and development plans) Then, based on load forecasting, utilities assess whether their distribution system can handle the forecasted load, and make plans where additional facilities are needed Ms Mirzayi stressed that both transmission and distribution planners review many alternative means to meet planned needs Ms Mirzayi continued that Xcel Energy is part of several different reliability planning groups that coordinate and promote electric system reliability at the regional and state levels to ensure compliance with North American Electric Reliability Corporation (NERC) standards (slide 16) PAGE 2 OF 4 MEETING MINUTES Mr Doyle turned the discussion to the specific need for the Project (slide 17) Part of a larger Northern Colorado Area Plan, this Project is needed to increase Xcel Energy's ability to serve the existing and future customers, increase electric service reliability, and meet growing and changing energy needs He described the existing system in the area (slide 19) Since 2015, almost 300 outages have occurred affecting more than 250,000 customers (slide 19) Mr Doyle pointed out that the surrounding counties do not have a 44 kV system, and noted this as one issue that Xcel Energy is trying to address with the Northern Colorado Area Plan The Northern Colorado Area Plan includes three planned projects 1) the Project discussed today (WAPA [Western Area Power Administration] Ault to Cloverly Transmission Project, 2) a planned Avery Substation in Windsor, and 3) a future Weld to Rosedale 230 kV Transmission Project (slide 20), located south of Greeley He reviewed concepts for the long-range transmission planning in the study area and compared the existing system to the proposed system in the study area (slides 21-23) Mr Doyle reviewed the components of the Project He pointed out that the new Husky Substation is already permitted by the Town of Ault, and Ms Horvath confirmed the location was specifically identified by the Town The location of the new Eaton -area substation is not fixed, he said, and the CWG will be asked to help Xcel Energy review a specific target area for studying site options for the location of the substation He noted that the existing Eaton Substation cannot be expanded because space is confined due to residential development in the immediate area He also noted that the new Eaton -area substation is no longer referred to as the `Graham Creek substation' because that name had a geographic connotation that might provide a misperception that Xcel Energy has a preconceived idea for the location of the substation Mr Doyle reviewed the Project description and proposed transmission structures in more detail (slides 24- 27) He then displayed the study area, and described the study process for siting and routing the new Eaton - area substation and the transmission lines (slides 28-30) He said at the next CWG meeting (planned for January 2020), the goal is to identify the substation target area for the new Eaton -area substation Then, within that target area, Xcel Energy will reach out to property owners to assess whether they are open to locating the substation on their land Mr Doyle continued that Xcel Energy and POWER Engineers have been collecting data on existing and planned land uses, including residences and proposed developments, and environmental resources in the study area that will be useful in the study process (slide 32) They also are identifying opportunities (such as existing transmission lines or linear infrastructure such as rail roads) and constraints to siting a transmission line (slides 33 and 24) In conducting an opportunity and constraints analysis in the study area, different `sensitivities' can be assigned to various resources to provide criteria for facility siting The sensitivity of particular resources varies from community to community, so the CWG is asked to provide input on the draft facility siting criteria for the Project (slide 35, also attached) The CWG members were asked to provide input on the draft facility siting criteria to Xcel Energy (by email, fax, in -person, or verbally) by November 13, 2019 Ryan Fagerberg asked if the input also could include additional resource categories — the response was yes, additional categories can be added Mr Doyle then reviewed the rest of the siting and routing process (slide 30) Mr Doyle explained that after the siting and routing process, which will include collaboration with the CWG and input from the public, Xcel Energy will submit a new permit application to Weld County for approval (slide 31) Ms Smith reviewed the comments and issues from the community that Xcel Energy will be considering in and responding to as part of the siting and routing study process (slides 36-38) The CWG meetings will provide an opportunity for the CWG members to provide additional input and context on relevant issues Ms Smith introduced other planned public outreach and engagement activities (slide 39) She said that three public open houses are planned in the study area to educate the public about the Project and solicit input Xcel Energy has briefed county and municipal staff on the Project and will be conducting meetings with potentially affected landowners in the future Three more CWG meetings are planned in January, March, and PAGE 3 OF 4 MEETING MINUTES April 2020. January 16, 2020 was identified by the group for the next CWG meeting during lunch hours (11;00 to 1:00). At the next CWG meeting, the group will review (1) system -planning information specific to the areas for locating the substation target area; (2) baseline land -use and environmental -resource information collected and mapped; (3) the preliminary results of the opportunities and constraints analysis; and 4) alternatives to study for the Eaton Area Substation and transmission lines. Ms. Smith displayed Xcel Energy's project website at xcelenergynortherncoloradoareaplan.com (slide 40). The project email address is: northerncolorado@xcelenergy.com. In closing, Mr. Doyle encouraged the CWG members to feel free to email requests to Xcel Energy for any additional, related topics that need discussion. A written summary of the meeting will be emailed to the CWG members within about a week.

One circuit would be installed initially and operated at 230 kV. • The new Husky Substation would replace the Xcel Energy Ault 44 kV Substation, which would be decommissioned. (In November 2018, a site plan for the new Husky Substation in the Town of Ault was submitted and was approved in February 2018.) • A transmission line would be constructed to support two circuits (double -circuit) from the new Husky Substation to a new Eaton -area substation. A 115 kV circuit would be installed initially and a 230 kV circuit would be installed in the future when additional electric service is needed. • The new Eaton -area substation would replace the existing Xcel Energy Eaton 44 kV Substation, which would be decommissioned. The new Eaton -area substation would accommodate upgrades to the local electrical distribution system. • A transmission line would be constructed to support two circuits (double circuit) from the new Eaton -area Xcel's existing Cloverly Substation. A 115 kV circuit would be installed initially and a 230 kV circuit would be installed in the future when additional electric service is needed. The existing 44 kV transmission line would remain in place and operational until the new Eaton -area substation to Cloverly Substation segment is constructed and energized; at which time the 44 kV line would be removed, but poles with distribution underbuild will remain.

Substations will contain an equipment enclosure, transformer, capacitor bank, and switches to support the distribution feeders. Typically, dead-end structures and static masts are approximately 55 to 62 feet tall.Typical busses are approximately 35 feet tall and electrical equipment enclosures are generally no taller than 15 feet. Grading and landscaping amenities can require additional area, typically increasing the substation site size. Design details will be determined through future engineering efforts. The total site size depends on the existing topography and visual screening opportunities. Project Study Area a; �S[5slaror -- COUNTY RUU II I 1 i � 1 I I ..-. COUNTY RD COUNRO 74 �'•'-...
