Washington DC, Baltimore, and their Maryland suburbs. Some of it finds its way
north and east to Philadelphia and Delaware. Only a small fraction flows south to
Northern Virginia.5
In the RTEP report, PJM concedes that the Loudoun line will serve needs in
Pennsylvania, Delaware, Maryland, the District of Columbia. and possibly other
load centers, in addition to Northern Virginia.'
