Calpine Mid-Atlantic LLC has proposed a 760-MW, combined cycle generating facility located in York County, Pa., said a system impact study from PJM Interconnection that is dated April 2014.
A system impact study is one of the intermediate steps in the process of working out project interconnection issues. The installed facilities for the Calpine project will have a total capability of 760 MW with 760 MW of this output being recognized by PJM as capacity. The project in-service date is in the second quarter of 2017.
This project, under queue #Y3-043, will interconnect with the PECO Energy transmission system at the Peach Bottom 500-kV substation. Project #Y3-043 was evaluated for compliance with reliability criteria for summer peak conditions in 2017. The project entered the queue in February 2013.
Also in the active PJM queue is a proposal from Calpine Mid-Atlantic Development LLC for a natural gas-fired facility located in Delta, York County, Pa. The installed facilities will have a total capability of 678 MW with 678 MW of this output being recognized by PJM as capacity, said a March 2013 system impact study by PJM. The proposed in-service date for this project is June 1, 2017. This second project, which entered the queue in October 2011 and is designated with queue number X3-068, will interconnect with Baltimore Gas and Electric‘s transmission system via a direct connection into the Graceton substation.
