Pepco Waterfront Substation

The Pepco Waterfront Substation project was a new substation installation for the Potomac Electric Power Company of Washington, D.C. It was a design-assist job with Coakley Williams Construction and their mechanical engineer, META Engineers. The building had to be designed to house and accommodate a new ABB turbine technology that Pepco was using to make power with a smaller footprint than their traditional power plants. The site in Southeast Washington, D.C. was selected because of its proximity to the newly constructed Nationals Park, home of the Washington Nationals, and the soon to be constructed Audi Field, home the D.C. United soccer franchise. The new power demands in this part of town required the use of new ABB technology.

Harris’ scope of work consisted of large ventilation fans, louvers and ductwork for the battery plant and buss duct, as well as CRAC units for the switchgear. There was also a fair amount of underground foundation drainage piping, as well as the installation of large underground oil retention pits and process piping from the transformer yards.
