Monthly Project Review November 2017

About $100m worth of new projects were announced in November, according to TransmissionHub data.

Four new projects were announced last month, including a new 138-kV transmission project in Harrison County, Ohio, proposed by Harrison Power Transmission LLC. The Harrison Power 138-kV Transmission Line Project involves the construction of about five miles of 138-kV line from the proposed Harrison Power, LLC (HPL) substation in the Harrison County Industrial Park to the newly built AEP Nottingham substation in Harrison County. The project would provide a connection from the proposed combined cycle gas-fired power plant planned for construction in the Harrison County Industrial Park to the AEP Nottingham substation, which is in Athens Township. The project’s estimated cost is $20m, with a proposed construction period of six months to be commenced in late 2018.

Brazos Electric Power Cooperative announced the new Brazos Electric Gyp to AEP Texas Benjamin 138-kV Transmission Line project in King and Knox counties in Texas. The proposed project, which would be designed, built, and operated as a single-circuit line, would begin at the new Brazos Electric Gyp substation, to be built adjacent to an existing Brazos Electric 138-kV transmission line in southeastern King County about 12 miles to 13.5 miles west of Knox City, Texas, depending on the final location of the station. From the Brazos Electric Gyp substation, the project would head generally to the northeast to the AEP Texas Benjamin substation, located on U.S. Highway 82, west of the City of Benjamin in Knox County. “Route N” has an estimated total cost of about $21.6m, of which about $10.8m would be the estimated cost for Brazos Electric, and about $10.8m would be the estimated cost for American Electric Power’s (NYSE:AEP) AEP Texas. According to the estimated schedule, construction of the facilities would begin in March 2019, and be completed in November 2019, which would also be when the facilities would be energized.

PPL Electric Utilities, subsidiary of PPL (NYSE:PPL), has plans for the new Breinigsville-Alburtis 500-kV Transmission Line project, which involves rebuilding the existing single-circuit line to a double-circuit configuration. The entire project would be built within existing right of way, and is needed to improve reliability in Lehigh County, Pa. The project has an in-service date of March 2019, and a total estimated cost of about $33m.

AEP’s Appalachian Power is planning the Cabin Creek-Clendenin Transmission Line Rebuild Project in Kanawha County, W.Va., which involves upgrading about 18 miles of the Cabin Creek-Clendenin line to 69-kV standards and adding equipment to local substations. The rebuilt line will reduce the likelihood of outages and improve overall reliability. Appalachian Power expects to complete the project by the end of 2020.

Five projects saw significant changes in November. For instance, IDACORP’s (NYSE:IDA) Idaho Power received a record of decision (ROD) from the U.S. Bureau of Land Management for the company’s planned Boardman to Hemingway Transmission Line Project. The ROD allows the BLM to grant right of way (ROW) to Idaho Power for the construction, operation, and maintenance of the project on BLM-administered land. The project includes the construction of a new 293-mile, 500-kV line that will stretch from Boardman, Ore., and terminate at a substation near Melba, Idaho. According to the ROD, construction of the project is planned to begin in 2020, placing the project in service between 2023 and 2025.

Vermont Green Line Devco LLC has withdrawn its application for the Vermont Green Line transmission project between Vermont and New York. The project involved a new 60-mile, underground and underwater transmission cable to deliver 400 MW of clean energy to New England. Vermont Green Line Devco said that circumstances beyond its control required it to withdraw the petition at this point.

Northern Pass Transmission LLC received approval from the U.S. Department of Energy for the company’s $1.6bn, 192-mile Northern Pass line, which is designed to deliver up to 1,090 MW of hydropower from Québec, Canada to Deerfield, N.H. Northern Pass Transmission LLC noted that the U.S. Forest Service is expected to issue a separate final ROD soon in response to Northern Pass Transmission’s application for a special use permit to allow burial of the transmission line through the White Mountain National Forest. 

Appalachian Power received approval by the Virginia State Corporation Commission to build the South Abingdon Extension project, which is an approximately $40m investment that involves building about four miles of 138-kV transmission line and a new substation, as well as upgrading three existing substations to improve reliability for area customers. Transmission line construction is expected to begin next spring, and be completed by the end of 2018, while construction of the new substation was to begin in November. The project is the first phase of the previously announced Abingdon and Washington County Area Improvements Project.

Finally, C and L Electric Cooperative Corporation is granted a certificate of public convenience and necessity (CCN) to build, own, and operate a new 115-kV transmission line beginning at Arkansas Electric Cooperative Corporation’s (AECC) Hermitage South switching station and terminating at CLECC’s new Hermitage substation, located in Bradley County, Ark., according to a Nov. 9 order signed by an Arkansas Public Service Commission administrative law judge. The project is needed to ensure reliability in the region, and project construction is anticipated to be completed on Dec. 31, 2018.
