PJM Interconnection has issued a System Impact Study, dated September 2015, that covers an assessment that has been performed by PJM and FirstEnergy in response to a request made by Hecate Energy LLC for the connection of a 10 MW (3.8 MW Capacity) solar photovoltaic project to the Antietam 34.5-kV substation.
This project, being pursued under PJM queue #AA1-122, would interconnect into the Potomac Edison transmission system. Potomac Edison is a FirstEnergy subsidiary. The project site is northeast of East Hagerstown, Md., at 12311 Little Antietam Road.
As defined by Hecate Energy, the project site will be located at a point approximately 2.8 miles from the Antietam substation. The direct connection of this project will be accomplished by extending the existing 34.5 kV bus at the Antietam substation.
Project AA1-122 was studied with a commercial probability of 100%.
