Monthly Project Review August 2017

Multiple new projects were announced in August, representing nearly $309m worth of investment, according to TransmissionHub data.

American Electric Power (NYSE:AEP), for instance, announced nine new projects last month.

One project that AEP’s AEP Ohio Transmission Company announced last month was the Ross-Ginger Switch 138-kV Transmission Line Project, which includes rebuilding approximately five miles of 69-kV line to 138-kV standards between the Ross substation and the Ginger switch. The approximately $10m project is part of the overall Ross-Jackson Area Improvements Project.

Another project announced by the company was the Ginger Switch-Vigo 138-kV Transmission Line Project, which involves rebuilding a portion of the existing 69-kV Berlin-Ross transmission line to a 138-kV transmission line that connects the Ginger switch to the Vigo substation. The approximately $10m project is also part of the overall Ross-Jackson Area Improvements Project.

AEP Ohio Transmission Company and AEP Ohio also announced last month the planned Liberty-Buckskin Area Improvements project, which includes rebuilding about 17 miles of the existing line in the current right of way (ROW), and in some cases supplementing current easements. The approximately $30m project is expected to be completed in summer 2020.

The companies also announced last month the proposed Springfield 138-kV Transmission Line Rebuild Project and Liberty 138-kV Transmission Line Rebuild Project, which represent an approximate $19m investment. Combined, those projects will replace about 12 miles of transmission line to improve reliability of the electric transmission grid in Ross and Jackson counties. The projects will run through Springfield, Jefferson, and Liberty townships in Ross County, as well as Coal, Liberty, Jackson, and Lick townships in Jackson County, the companies added.

Finally, the companies announced the New Albany Breakthrough Overhead Line Design (BOLD) Transmission Line Project in August. The project includes replacing 6.5 miles of existing 345-kV transmission lines with new 345-kV and 138-kV transmission lines, the companies said. The existing wooden structures will be replaced with BOLD structures, which the companies said allow more energy to be delivered in a smaller footprint using a shorter structure height in a more contemporary design. The approximately $30m project is designed to ensure reliability, and is expected to be completed in fall 2019.

Indiana Michigan Power, subsidiary of AEP, has plans for the new Three Rivers Transmission Line Rebuild Project in Michigan. The approximately $13m project involves rebuilding approximately six miles of 69-kV transmission line, constructing the new Ripple substation, and retiring the existing Three Rivers substation. The project is needed to ensure reliability, and is expected to be completed by summer 2019.

AEP’s Southwestern Electric Power Company has plans for a new project in Louisiana that involves the new Leaside Way substation and three new 138-kV transmission lines: Leaside Way to Southwest Shreveport, Leaside Way to Stonewall and Leaside Way to Western Electric. The project is designed to ensure reliability in the region at an estimated cost of about $24.7m.

In order to address reliability concerns, AEP’s Kentucky Power has put forth the Hazard-Wooton Project, which includes a rebuild of seven miles of existing 161-kV transmission line. The $30m project, located in Perry and Leslie counties in Kentucky, is expected to be completed in fall 2019.

Entergy Texas Inc., subsidiary of Entergy (NYSE:ETR),  is proposing the Rocky Creek or Quarry to Lewis Creek 230-kV Transmission Line in Texas. “Route 3,” which is the preferred route, has the third greatest length utilizing existing transmission line ROW at 33.93 miles, and is the least costly of the 19 proposed primary alternative routes at about $120.5m. The project is needed to alleviate congestion in southeast Texas, and is expected to be energized in June 2020.

Two projects were completed in August. Xcel Energy (NYSE:XEL) and Otter Tail Power last month announced the completion of the 70-mile, $140m Big Stone South-Brookings County 345-kV transmission line project in South Dakota. The companies are joint owners of the project, which runs between the Big Stone South substation near Big Stone City and the existing Brookings County substation about 10 miles northeast of Brookings. Otter Tail Power is a subsidiary of Otter Tail Corporation (NASDAQ:OTTR).

Great River Energy on Aug. 23 told Minnesota regulators – on behalf of itself and Minnesota Power – that construction of the Motley Area 115-kV Project was complete. As noted on Great River Energy’s website, the company built about 16.5 miles of new 115-kV overhead transmission line in southern Cass County, eastern Todd County, and northern Morrison County to ensure the reliability of electric service to the members of Crow Wing Power.

Finally, Dominion Virginia Power, subsidiary of Dominion Energy (NYSE:D), received construction authorization from the Virginia State Corporation Commission for the company’s planned Remington-Gordonsville 230-kV Double Circuit Transmission Line. The company is proposing to build, entirely along and primarily within existing ROW, about 38.2 miles of the 230-kV Remington-Gordonsville Line #2153 in Fauquier, Culpeper, Orange, and Albemarle counties between its existing Remington substation in Fauquier County and the existing Gordonsville substation in Albemarle County. The approximate $104.6m project is expected to be completed in 2020.
