Monthly Project Review October 2017

Four projects were announced in October totaling nearly $107m, according to TransmissionHub data.

American Electric Power’s (NYSE: AEP) AEP Ohio and AEP Ohio Transmission Company, Inc., for instance, announced the new Friendship-Portsmouth Transmission Line in Ohio. The project will involve building about nine miles of 69-kV transmission line and upgrading two substations to improve service reliability in the Scioto County area. The project is expected to be complete in spring 2020 at a cost estimate of about $25m.

Appalachian Power and its affiliate West Virginia Transmission Company plan to invest in the new Becco-Kopperston Transmission Line Project in West Virginia.  The project includes rebuilding 13 miles of single-circuit, 69-kV transmission line; building three miles of new double-circuit, 138-kV transmission line; building the new Lacey Branch substation; making upgrades to existing substations; and replacing a mile of wire to improve communication between substations. The approximately $60m project will improve reliability and is expected to be in service in June 2019. Appalachian Power is a subsidiary of AEP.

Electric Transmission Texas (ETT) is planning to build a new 345-kV single- and double-circuit transmission line in Pecos County, Texas, to interconnect two proposed solar facilities.  The line would be built as a double-circuit 345-kV line, starting from the existing Lower Colorado River Authority Transmission Services Corporation Bakersfield 345-kV substation and then heading eastward to the RE Maplewood LLC Red Barn substation, where one circuit of the double-circuit 345-kV line would terminate and then continue as a single-circuit 345-kV line to the east, and then north before terminating at the Midway Solar LLC Waymark substation. The Bakersfield to Red Barn Double-Circuit and Red Barn to Waymark Single-Circuit 345-kV line has an estimated cost of about $15.5m, with a completion date of spring 2019. ETT is a joint subsidiary of AEP and Berkshire Hathaway Energy Company.

Carroll Electric Cooperative Corporation (CECC) is proposing a project in Benton County, Ark., that involves a new transmission line that will run from the existing Centerton-Highfill transmission line to a new Morning Star substation. Another line would run from the Morning Star substation to the NACA substation. The estimated $6.5m project will be built to 161-kV standards but operate at 69-kV and is needed to ensure reliability.

Three projects saw significant changes in October. The Public Service Commission of Wisconsin, in an Oct. 4 letter to American Transmission Company (ATC), told the company that its request for a minor route adjustment (MRA) to the route of a new 138-kV line is approved. The Spring Valley-North Lake Geneva Transmission Line Project involves a 23-mile, 138-kV transmission line that would stretch from the existing North Lake Geneva substation in Walworth County to the Spring Valley substation in western Kenosha County. Included with the project is the new Balsam substation, and a new 69-kV line that will connect the Balsam substation to the existing Twin Lakes substation in Twin Lakes, Wis.

The Public Utilities Commission of Ohio staff, in an Oct. 27 report filed with the Ohio Power Siting Board (OPSB), concluded that AEP Ohio Transmission Company (AEP Ohio Transco) has demonstrated the basis of need for the proposed West Bellaire-Glencoe 138-kV Transmission Line Rebuild Project, which is a baseline project required by PJM Interconnection. The project involves installing a new 138-kV overhead electric transmission line for a distance of about six miles between the existing West Bellaire and Glencoe substations. AEP Ohio Transco plans to place the line in service by July 2019, at a cost of about $22.5m.

Finally, construction is underway on FirstEnergy’s (NYSE:FE) Campbell-Keisters 138-kV Transmission Rebuild Project, which involves replacing approximately 7.5 miles of existing 69-kV transmission poles and wires with new structures capable of supporting 138-kV operations. The upgraded line will extend between electric substations in Slippery Rock Township, Butler County, and Grove City Borough, Mercer County. The $14.5m line is needed to enhance reliability in the region.
