Monthly Project Review July 2017

Six new transmission projects, representing $583.9m, were announced in July, according to TransmissionHub data.

For instance, in order to address reliability concerns, Clay County Electric Cooperative Corporation has plans for a new estimated $7.5m, approximately 7.5-mile, 161-kV transmission line, which would extend between the Baltz Lake and Ingram substations, and is expected to be completed by late 2018.

Indiana Michigan Power, subsidiary of American Electric Power (NYSE:AEP), has plans for the new Elkhart Network Improvements Project in northeastern Indiana. The project involves building about two miles of 69-kV transmission lines between the Harrison Street and Lusher Avenue substations, as well as about two miles of 69-kV line between the Harrison Street substation and existing Concord-Wolf transmission line. The project will also include various underground distribution network upgrades in downtown Elkhart to ensure reliability. The $34m project is expected to be completed by mid-2019.

AEP’s AEP Texas Inc., announced the new estimated $6.1m Solstice to Roserock project in July. The project involves a new 138-kV transmission line from the AEP Solstice substation to the Roserock Point of Interconnection in Pecos County, Texas. The project would provide transmission service for a new solar farm, and is expected to be completed in 2019.

In order to reduce power outages, AEP’s Appalachian Power is proposing the new Lincoln-Logan Power Improvements project. The planned project involves building 15 miles of new single-circuit, 138-kV transmission line and nine miles of double-circuit, 138-kV transmission line. In addition, two new substations will be built, and the existing Sheridan substation will be retired. Finally, 17 miles of existing 69-kV transmission line will also be retired. Appalachian Power expects to complete the project by the end of 2020, at a cost of $90m.

The City of Garland, Texas announced the new Dent Road to Shelby project. The new transmission line will be approximately four miles in length and operate at 138 kV. The estimated $6.3m project is needed to ensure reliability in the region and is expected to be completed in 2019.

The New York Power Authority (NYPA) has plans for the new Moses-Adirondack Smart Path Reliability Project, which includes replacing 78 of the 86 miles on each of two existing transmission lines in St. Lawrence and Lewis counties in New York. The lines will be capable of transmitting up to 345 kilovolts, but would be operated in the near term at the current level of 230 kV. When completed, the project will allow new renewable capacity from upstate New York to be carried to high demand regions downstate. NYPA expects to complete the project in 2024, at a cost of $440m.

One project was energized in July. Entergy Arkansas, Inc., subsidiary of Entergy (NYSE:ETR), completed a new 25-mile, 230-kV transmission line in Chicot and Desha counties. The Lake Village Bagby to Reed Switching Station 230-kV Transmission Line will improve reliability in the region and was completed at a cost of $26.4m.

Finally, Dominion Energy (NYSE:D) was granted a project permit by the Norfolk District of the U.S. Army Corps of Engineers for the company’s planned Surry-Skiffes Creek in Virginia. The project includes an approximately eight-mile, 500-kV transmission line that will supply needed capacity to serve the local area; support local growth and economic development in central and eastern Virginia; and provide reliability improvements for fewer service interruptions and shorter durations when an outage does occur. The estimated $270m project is expected to take 18-20 months to complete once full construction is underway.
