New, updated and reliable infrastructure remains the key to future growth for the community. Duquesne Light Company is planning to build a new 138 kilovolt (kV) electric transmission line from Universal Substation to Plum Substation, which spans approximately five miles in the Municipality of Penn Hills, the Municipality of Monroeville, and the Borough of Plum in Allegheny County, Pennsylvania.  This new transmission line is needed to meet increased demand for electrical power and to ensure reliable electric service for eastern Allegheny County. Although the final design of the transmission line is not complete, the line includes approximately 40 self-supporting steel monopoles on concrete foundations.  The monopoles will range in height from 105 feet to 150 feet.
