PJM Generation Interconnection Feasibility Study Report - AH1-931
4. Analysis
Summer peak load flow, light load and short circuit analyses were performed on the PJM 2026 base case with
all earlier-queued projects modeled. The overload of the Ardley-Pine Fork 138 kV line (up to 118 percent of its
emergency rating) is driven by AH1-931 together with three other AH1 positions; AH1-931's share of the
reconductoring cost reflects its distribution factor. No short circuit violations were found. No affected system
impacts were identified at this stage.
5. Cost allocation and next steps
Quote starts. The costs above are planning-level estimates with an accuracy of about plus or minus 50 percent. Quote ends. Network
upgrade costs may change as earlier-queued projects withdraw or as later studies refine the cases. To remain in
the queue, the Interconnection Customer must execute the System Impact Study agreement and pay the study
deposit. The System Impact Study will confirm the upgrades, the capacity interconnection rights and the cost
allocation, and will be followed by a Facilities Study and an Interconnection Service Agreement.
The Transmission Owner estimates 36 to 42 months from execution of an interconnection agreement to
complete the switching station and the network upgrades, which may constrain the requested in-service date.
6. Interconnection Customer requirements
The Interconnection Customer is responsible for the project substation, the 138 kV gen-tie to the switching
station, protection and control compatible with the Transmission Owner's standards, telemetry to PJM, and
meeting the ride-through and reactive power requirements of the PJM tariff.
