Exelon Generation Co. LLC has proposed 20-MW battery storage project at an existing wind generating facility located in Garrett County, Maryland, said an October 2016 study on the project from PJM Interconnection.
This project, under PJM queue #AB1-076, is a battery storage facility of 20 MW in size, with 0.0 MW of this output to be recognized by PJM as capacity. The installed facilities of both wind and battery projects – U2- 073 and AB1-076 – will have a total capability of 80 MW with 5.2 MW of this output being recognized by PJM as capacity.
The proposed in-service date for this battery project is Dec. 31, 2016. This study does not imply a Potomac Edison commitment to this in-service date. AB1-076 will interconnect with the Potomac Edison system through existing point of interconnection of prior queue project U2-030. U2-030 is the 60-MW Fourmile Ridge Wind Project.
The intent of this System Impact Study is to determine a plan, with approximate cost and construction time estimates, to connect the subject generation interconnection project to the PJM network at a location specified by Exelon. It is a mid-point in the PJM queue process.
