Duquesne Light: Construction on Brunot Island-Crescent project scheduled to begin in 2019

Duquesne Light said that construction on the Brunot Island-Crescent Transmission Reliability Project, which involves updating a transmission line that stretches 15 miles from the company’s substation in Crescent Township, Pa., to its substation located on Brunot Island on the Ohio River, just west of downtown Pittsburgh, is scheduled to begin in 2019, and is expected to be completed by 2021.

Customers in Moon Township, Robinson Township, Kennedy Township, Crescent Township, McKees Rocks Borough, and the City of Pittsburgh are served by a network of 138-kV transmission lines that were originally installed when the region looked different than it does today, the company said in its statement, adding that that network of lines needs to be upgraded to better serve customers.

While the final design of the line is not complete, the line will include 110 self-supporting steel monopoles on concrete foundation, standing less than 200 feet tall, the company said, noting that its employees and associates will conduct field studies and soil testing over the next few months.

The company also noted that it will host multiple open house meetings to gather input and answer questions.

A company spokesperson told TransmissionHub on March 6 that the project cost is about $40m, and that PJM Interconnection has already reviewed, provided feedback, and incorporated the project into its regional plan.

Duquesne Light said that the project is part of its “Larger than Light” commitment to invest in more than $2.9bn in infrastructure and technology upgrades between 2011 and 2021.

As noted on the company’s website, other current infrastructure projects are the Universal-Plum Reliability Project and the South Hills Capacity Project.

Of the Universal-Plum project, the company said that it is planning to build a new 138-kV electric transmission line from the Universal substation on Jefferson Road in the Municipality of Penn Hills, Pa., to the Plum substation on Fontana Dr., in the Borough of Plum, Pa., spanning about five miles in the Municipality of Penn Hills, the Municipality of Monroeville, and the Borough of Plum in Allegheny County, Pa.

The new line is needed to meet increased demand for electrical power, as well as to ensure reliable electric service for eastern Allegheny County, the company said.

The final design of the line is not complete, but the line includes about 40 self-supporting steel monopoles on concrete foundations, the company said, noting that the monopoles will range in height from 105 feet to 150 feet.

The project timeline extends from January 2018 through December 2018, the company said.

Of the South Hills Capacity Project, Duquesne Light noted that West Penn Power and Duquesne Light customers in Collier, Scott, Upper St. Clair and Bethel Park Townships in Pennsylvania are served by a network of 138-kV transmission lines, and that in order to maintain a level of service and reliability, while increasing the overall capacity and resiliency of the grid in that area, Duquesne Light is planning to replace the existing transmission line wires.

The project involves Duquesne Light’s Woodville substation in Scott Township and the transmission tower located on McMurray Road in Bethel Park, the company said, noting that the project timeline extends from September to June 2018.
