Definitions
Transmission Owner Interconnection Facilities: Facilities that are owned, controlled, operated and maintained by the Transmission Owner on the Transmission Owner’s side of the Point of Change of Ownership to the Point of Interconnection, including any modifications, additions or upgrades made to such facilities and equipment, that are necessary to physically and electrically interconnect the Generating Facility with the Transmission System or interconnected distribution facilities.
Stand Alone Network Upgrades: Network Upgrades, which are not part of an Affected System, which a Project Developer may construct without affecting day-to-day operations (e.g. taking a transmission outage) of the Transmission System during their construction.
Network Upgrades: Modifications or additions to transmission-related facilities that are integrated with and support the Transmission Provider’s overall Transmission System for the general benefit of all users of such Transmission System. Network Upgrades have no impact or potential impact on the Transmission System until the final tie-in is complete.
Notes
Note 1: PJM Open Access Transmission Tariff (OATT), Part VII, Subpart D, section 307.5 outlines cost allocation rules. The rules are further clarified in PJM Manual 14H, section 4.2.6. PJM shall identify the New Service Requests in the Cycle contributing to the need for the required Network Upgrades within the Cycle. All New Service Requests that contribute to the need for a Network Upgrade will receive cost allocation for that upgrade pursuant to each New Service Request’s contribution to the reliability violation identified on the transmission system in accordance with PJM Manuals.
Note 2: There will be no inter-Cycle cost allocation for Interconnection Facilities or Network Upgrades identified in the System Impact Study costs identified in a Cycle; all such costs shall be allocated to New Service Requests in that Cycle.
Note 3: For Project Developers with System Reinforcements listed: If this project presents cost allocation to a System Reinforcement indicates $0, then please be aware that as changes to the interconnection process occur, such as other projects withdrawing, reducing in size, etc, the cost responsibilities can change and a cost allocation may be assigned to this project. In addition, although this project presents cost allocation to a System Reinforcement is presently $0, this project may need this system reinforcement completed to be deliverable to the PJM system. If this project desires to come into service prior to completion of the system reinforcement, the Project Developer will need to request PJM to perform an interim study to determine if they would be deliverable for all or a portion of their output for each delivery year until the system reinforcement is complete.
Note 4: Please see the ‘Affected Systems Studies’ section of this Phase II SIS report for details on your project’s need for an Affected Systems Study. If your project requires an Affected Systems Study, the Affected Systems impacts may not be available from the Affected System Operator at the time of the PJM Phase II SIS. Therefore, the cost in this section would not reflect any required upgrades by the Affected System until the study is completed. If your project requires an Affected Systems Study and your results are not provided for Phase II SIS, PJM anticipates providing them in the Phase III SIS per Tariff Part VII.D.312.
Readiness Deposit
Per Tariff Part VII, Subpart D, section 311 (Decision Point II) A.1.b and PJM Manual 14H, section 6.2, Readiness Deposit #3 (RD3) are funds committed by the Project Developer or Eligible Customer based upon the applicable contribution to Network Upgrades as defined below. Readiness Deposits are not used to fund studies nor to offset Security.
During Decision Point II (DP2), the Project Developer or Eligible Customer is required to submit Readiness Deposit #3, which is calculated as 20% of cost allocation for required Phase II Network Upgrades minus Readiness Deposit #1 & Readiness Deposit #2.
Note 1: “Network Upgrades” referred to in the calculation include both (i) the Physical Interconnection Network Upgrades and (ii) the System Reliability Network Upgrades as shown in the Cost Summary table.
Note 2: Readiness Deposit #1 (RD1) = ($4,000 * Project Size (MW))
Note 3: Readiness Deposit #2 (RD2) = 10% of cost allocation for required Network Upgrades minus RD1. Readiness Deposit #2 (RD2) can be zero, but may not be a negative number.
Note 4: Readiness Deposit #3 can be zero, but may not be a negative number.
Readiness Deposit #3 Due for Project AG2-518
Readiness Deposit #3 has been calculated for the project based on the Phase II System Impact Study results and is shown in the table below. This Readiness Deposit #3 must be provided at Decision Point II through either a wire transfer or letter of credit per Manual 14H, Section 6.2.
Readiness Deposit #3 Due for AG2-518

Based on the scope of work for the Interconnection Facilities, it is expected to take 30 month(s) after the signing of a Generator Interconnection Agreement (as this is a FERC connection) and construction kickoff call to complete the installation of the physical connection work. This assumes that there will be no environmental issues with any of the new properties associated with this project, that there will be no delays in acquiring the necessary permits for implementing the defined interconnection work, and that all system outages will be allowed when requested.
Note that the TO findings were made from a conceptual review of this project. A more detailed review of the connection facilities and their cost will be identified in a future study phase. Further note that the cost estimate data provided should be considered high level estimates since it was produced without a detailed engineering review. The Project Developer will be responsible for the actual cost of construction. TO herein reserves the right to return to any issues in this document and, upon appropriate justification, request additional monies to complete any reinforcements to the transmission systems.
Remote Terminal Work: During Phase II of the PJM interconnection process, TO’s System Protection Engineering Department will review transmission line protection as well as anti-islanding required to accommodate the new generation and interconnection substation. System Protection Engineering will determine the minimal acceptable protection requirements to reliably interconnect the proposed generating facility with the transmission system. The review is based on maintaining system reliability by reviewing TO’s protection requirements with the known transmission system configuration which includes generating facilities in the area. This review may determine that transmission line protection and communication upgrades are required at remote substations.

Executive Summary
New Service Requests AG2-152, AG2-272, AG2-518, AH1-098, AH1-144, AH1-145, AH1-269 and AH1-314 in PJM Transition Cycle 2, Cluster 24 are listed in Table 1. below. This report will cover the dynamic analysis of Cluster 24 projects.
This analysis is effectively a screening study to determine whether the addition of the Cluster 24 projects will meet the dynamics requirements of the NERC, AEP and PJM reliability standards.
Cluster 24 projects were dispatched for stability analysis according to the following scenarios:
a) Scenario 1: AH1-098 dispatched at full MFO injection at the POI with PV MW contribution maxed out and no/reduced MW contribution from BESS.
b) Scenario 2: AH1-098 dispatched at full MFO injection at the POI with BESS MW contribution maxed out, and no/reduced PV MW injection.
c) Scenario 3: AH1-098 dispatched at full MFO injection at the POI with PV and BESS MW contribution proportional to their capacity.
d) Scenario 4: AH1-098 dispatched to full capacity with PV and BESS MW injection maxed out.
This report describes a dynamic simulation analysis of TC2 Cluster 24 for dispatch Scenario 3 as part of the overall system impact study.
The load flow scenario for the analysis was based on the RTEP 2028 Summer Peak, modified to include applicable projects. Cluster 24 projects have been dispatched online at maximum power output, with 1.01 pu voltage at the terminal bus.
Transition Cycle 2 Cluster 24 will be tested for compliance with NERC, PJM and other applicable criteria. The contingencies will be studied with a 20 second simulation time. Contingencies to be studied include:
a) Steady-state operation (Category P0);
b) Three-phase faults with normal clearing time (and with unsuccessful high-speed reclosing) (Category P1);
c) Single-phase bus faults with normal clearing time (Category P2);
d) Single-phase faults with stuck breaker (Category P4);
e) Single-phase faults placed at 80% of the line with delayed (Zone 2) clearing at line end remote from the fault due to primary communications/relay failure (Category P5);
f) Three-phase faults with loss of multiple-circuit tower line; (and with unsuccessful high-speed reclosing) (Category P7).
High Speed Reclosing (HSR) facilities were found in the vicinity of TC2 Cluster 24 projects.
Prior outage scenarios will not be considered for this study.
For all simulations, the queue project under study along with the rest of the PJM system were required to maintain synchronism and with all states returning to an acceptable new condition following the disturbance.
For all the fault contingencies tested on the 2028 peak load case:
a) Cluster 24 projects were able to ride through the faults (except for faults where protective action trips a generator(s)),
b) The system with Cluster 24 projects included is transiently stable and post-contingency oscillations were positively damped with a damping margin of at least 3% for interarea modes and 4% for local modes.
c) Following fault clearing, all bus voltages recovered to a minimum of 0.7 per unit after 2.5 seconds (except where protective action isolates that bus).
d) No transmission element tripped, other than those either directly connected or designed to trip because of that fault.
The IPCMD and IQCMD states in the REGCA1 models of all units of Cluster 24 showed erratic behavior for some contingencies in which queue project has been disconnected as part of the contingency event. Since the machines are disconnected and no active or reactive power is injected into the system, this behavior is likely fictitious and a limitation of the software. This does not cause instability in the system.
Tripping was observed for several contingencies (P4.081, P4.082, P5.39, and P5.48) under the initial study conditions. Upon updating the fault impedance values based on Aspen short circuit case, the tripping issues were resolved, and the system remained stable for these contingencies.
AH1-098 both Solar and BESS units tripped under several contingencies. Upon updating Vdip to 0.8 (Original value was 0.9) and Vup to 1.2 (Original value was 1.1) for both units resolved all tripping issue.
Fictitious frequency response at AH1-145 generator bus tripped the queue project for several contingencies (P1.073, P1.075 and P1.076). Therefore, the frequency relay pickup times for were set to 20 seconds to avoid fictitious frequency tripping of the unit.
AG2-272 generating units exhibited slow reactive power recovery within the 20 second simulation window for several contingencies. This issue did not cause instability in the system. The reactive power droop compensation was enabled and tuned by updating Kc to 0.15 (original value was 0) which resolved the slow reactive power response.
AH1-269 generating units exhibited slow reactive power recovery within the 20 second simulation window for several contingencies. This issue did not cause instability in the system. The reactive power droop compensation was enabled and tuned by updating Kc to 0.1 (original value was 0) which resolved the slow reactive power response.
AH1-314 generating units exhibited slow reactive power recovery within the 20 second simulation window for several contingencies. This issue did not cause instability in the system. The reactive power droop compensation was enabled and tuned by updating Kc to 0.1 (original value was 0) which resolved the slow reactive power response.
The active power for AG2-152 did not recover to the pre fault value for contingency P7.21 due inadequate reactive power response. The reactive power droop compensation gain Kc parameter was updated to 0.1 which resolved the active power recovery issue.
Smith Mountain generators showed positively damped oscillations which did not settle during the 20 second simulation window. The selected contingencies were run for 30 seconds, and the oscillatory signals achieved a flat response at the end of the 30 second simulation time period.
No mitigations were found to be required.

Affected System - PJM Identified Violations
As part of PJM's analysis, per Tariff Part VII.G.336 & Manual 14H, Section 13, PJM evaluated the potential impacts on tie line facilities between PJM and an affected system entity, which were identified per PJM planning analysis criteria. This upgrade may be required on the affected system portion of the tie line along with cost allocation of such upgrade if applicable, in coordination with the affected system. Depending on the affected system, this project may not be contingent on upgrade based on PJM planning analysis criteria, but may be contingent on this upgrade based on the Affected System Operator's planning criteria, provided in the Affected Systems Study Section, herein.
Affected System - Non-PJM Identified Violations
In accordance with PJM Tariff Part VII, Subpart D, section 310.A and as outlined in PJM Manual 14H, Sections 4.5 and 13, in Phase II of the Cycle, PJM provides the Affected System Operator any updates on the PJM projects that require an Affected Systems Study based on their response at DP1. New Service Requests that require an Affected Systems Study are required to enter into an Affected Systems Study Agreement with the Affected System Operator, as applicable, prior to the close of DP2 or they will be withdrawn from the Cycle.
If the Project Developer already entered into the necessary agreement and the results are available, PJM will supply them in the Phase II SIS report. See below for the status of any required Affected Systems Study. A status of “Pending” means that the study is not yet completed by the Affected System Operator. If your project requires an Affected Systems Study and your results are not provided for Phase II SIS, PJM anticipates providing them in the Phase III SIS per Tariff Part VII.D.312.

ContingentTopology Changing Note 1: Although AG2-518 may not presently have cost responsibility for this upgrade, AG2-518 may need this upgrade in-service to be deliverable to the PJM system. If AG2-518 desires to come into service prior to completion of the upgrade, the Project Developer will need to request PJM to perform an interim study to determine if they would be deliverable for all or a portion of their output for each delivery year until the upgrade is complete. Note 2: This topology changing reinforcement was developed by the transmission owner and modeled in PJM analysis to address cycle overload(s). A flowgate that this project contributed to was identified as requiring this topology reinforcement.
