Project Description: Eastside Loop Expansion - Phase I Name or Designation of Proiect Provide a general description of the project, including the design voltage rating (kV), the operating voltage (kV), the CREZ Zone(s) (if any) where the project is located (all or in part), any substations and/or substation reactive compensation constructed as part of the project, and any series elements such as seetionalizing switching devices, series line compensation, etc. For HVDC transmission lines, the converter stations should be considered to be project components and should be addressed in the project description. El Paso Electric Company's ("EPE") System Planning group has identified the need to expand its transmission system in the far eastern portion of El Paso County between US 62-180 (Montana Ave.) and Interstate 10. As a whole, the project is described as the Eastside Loop Expansion and will encompass (1) upgrading the capacity and/or voltage of two existing lines that already extend into the area, (2) constructing two new substations (Pine and Seabeck) along those two existing lines, and (3) constructing two new transmission lines: one line to connect the two new substations (Pine and Seabeck) to each other and one line to connect the new Seabeck Substation to the San Felipe Substation, thereby looping the substations together and providing additional transmission flow paths for EPE's 115 kV transmission system. The new and upgraded transmission system facilities will all be designed and operated at 115 kV. A diagram of the Eastside Loop Expansion is provided as Attachment 2. This particular CCN application addresses what is termed Phase I of the Eastside Loop Expansion and involves the new 115 kV transmission line that will connect the two new substations: Pine Substation and Seabeck Substation (the Project). Pine Substation will be located in the northern portion of the project area approximately 1.51 miles southeast ofthe intersection of United States Highway ("US") 180 and Ballard St/Desert Storm Rd., on the south side of La Pine Ave., across the street from the existing Coyote to Dell City transmission line. This line is already certificated at 115 kV but the capacity of the existing line between Coyote and Pine will be upgraded by reconductoring it with 954 ACSR conductor. Seabeck Substation, approximately nine miles south of Pine Substation, will be located at the northeast corner of the intersection of Seabeckand Farm Road 1281 (Horizon Blvd.) and adjacent to the existing Horizon to Hueco transmission line. This line is certificated at 69 kV but has been operating at 14 kV due to low load levels at Hueco. The line will be reconductored and rebuilt between Horizon Substation and Seabeck on new structures within the existing right-of-way and upgraded to 115 kV. The third substation that is a part of the Eastside Loop Expansion is the San Felipe substation, located approximately 12 miles south of Seabeck Substation. San Felipe substation will be constructed in 2022 (prior to the Eastside Loop Expansion) to replace the existing Felipe Substation to support the distribution system in the area, and it will be located in an undeveloped area just south of I-10, approximately 1,700 feet southeast of Fabens Rd. The new 115 kV transmission line that will connect Seabeck Substation and San Felipe Substation will be addressed in a separate CCN application as Phase 2 of the Eastside Loop Expansion. The Project is in El Paso County, TX. 3 Effective June 8,2017 3 Standard Application for a Certificate of Convenience and Necessity for a Proposed Transmission Line and Application for a Certificate of Convenience and Necessity for a Proposed Transmission Line Pursuant to 16 TAC § 25.174 If the project will be owned by more than one party, briefly explain the ownership arrangements between the parties and provide a description of the portion(s) that will be owned by each party. Provide a description of the responsibilities of each party for implementing the project (design, Right-of-Way acquisition, material procurement, construction, etc.). This is not a joint application. If applicable, identify and explain any deviation in transmission project components from the original transmission specifications as previously approved by the Commission or recommended by a PURA §39.151 organization. Not applicable. 5. Conductor and Structures: Conductor Size and Type: 954 ACSR 'rail' Number of Conductors per Phase: 1 Continuous Summer Static Current Rating (A): 998 Continuous Summer Static Line Capacity at Operating Voltage (MVA): 185 Continuous Summer Static Line Capacity at Design Voltage (MVA): 185 Type and Composition of Structures: The typical structure will be a delta or vertical steel monopole, either self-supported or on a drilled pier foundation.. Height of Typical Structures: 95' Estimated Maximum Height of Structures: 110' Explain why these structures were selected; include such factors as landowner preference, engineering considerations, and costs comparisons to alternate structures that were considered. Provide dimensional drawings of the typical structures to be used in the project. Monopole structures were selected as the primary structure to allow for smaller right-of-way ("ROW") widths. Steel structures were selected for reliability. Dimensional drawings of the typical structures are provided as Attachment 3. 4 Effective June 8, 2017 4 Standard Application for a Certificate of Convenience and Necessity fur a Proposed Transmission Line and Application for a Certificate of Convenience and Necessity for a Proposed Transmission Line Pursuant to 16 TAC § 25.174 For joint applications, provide and separately identify the above-required information regarding structures for the portion(s) of the project owned by each applicant.
