PJM Interconnection Module Package

Stage 1: Application Phase, Phase I System Impact Study and Decision Point I

• Support you through the Application Phase of the Cycle under Tariff Part VIII and Manual 14H, including review of the technical information you enter in PJM's data submission tool (Point of Interconnection, Maximum Facility Output (MFO), Capacity Interconnection Rights, fuel type, storage charging, MWh and hour class, equipment configuration) and responses to PJM's deficiency review. You submit the application.
• Develop the plant power flow (.idv) and dynamic (.dyr) models per the PJM Dynamic Model Development Guidelines, avoiding models on PJM's Unacceptable Models List. For a non-synchronous facility in a Cycle under PJM's Order No. 2023 compliance revisions, prepare the appropriately parameterized PSS/E library model and integrate the validated user-defined root-mean-square (RMS) model from the original equipment manufacturer (OEM), since the application must carry both, plus a validated electromagnetic transient (EMT) model where PJM requires one with the application.
• Perform the PJM Model Testing Requirements on a single machine infinite bus: MFO assessment, power factor assessment, flat start test, voltage ride-through test, momentary cessation review and primary frequency response check.
• Prepare the Dynamic Model Report, the Dynamic Model Checklist and the comparison table of Data Application form values against PSS/E model values that PJM requires to avoid data deficiency notices.
• Coordinate with inverter, turbine and plant controller manufacturers to obtain models, parameters and reactive capability curves that match the equipment in the application.
• Prepare the load flow and short-circuit data PJM requests through its data submission tool.
• Support you at the scoping meeting PJM holds to confirm the Point of Interconnection for modeling purposes.
• Review the Phase I System Impact Study load flow results and the Phase I base case (once our engineers have PJM Critical Energy/Electric Infrastructure Information (CEII) access) and advise you on your Decision Point I choices.
• At Decision Point I, update the dynamic, short-circuit and load flow data for any modification Manual 14H allows and prepare the data PJM needs for the Phase II System Impact Study.
• Prepare the model package PJM requires when you pursue one of its parallel processes: Surplus Interconnection Service, Replacement Generation Interconnection Service or the temporary Expedited Interconnection Track, whose application also requires a PSCAD model built to the PJM EMT Model Development Guidelines.

Stage 2: Phase II and Phase III System Impact Studies and Decision Points II and III

• Review the Phase II System Impact Study results, including the stability and short circuit analyses, and support you in resolving identified plant instability through model and control-setting changes within the modifications Manual 14H allows.
• Develop the PSCAD model of the plant up to the Point of Interconnection per the PJM EMT Model Development Guidelines for submission at Decision Point II.
• Perform PJM's PSCAD Model Quality Tests (functional tests, fault ride-through, voltage ride-through profiles, system strength, phase angle change, rate of change of frequency and frequency ride-through settings) and benchmark the PSCAD model against the PSS/E model.
• Prepare the combined Model Quality Tests and Benchmark Report and coordinate with the model supplier on the PSCAD Model Requirements Checklist, which PJM requires the supplier to complete as an attestation.
• Update the PSS/E and PSCAD models for any Permissible Technological Advancement you elect at Decision Point II.
• Provide model data to support an Affected System study when PJM notifies you that one is required.
• Review the Phase III System Impact Study retool of load flow, short circuit and stability results, and any EMT study PJM performs on the plant, and respond to PJM data requests before Decision Point III, when no modifications are permitted.

Stage 3: Final Agreement Negotiation Phase and GIA Implementation

• Review the technical specifications in the draft GIA tendered by PJM against the studied model.
• Track equipment and setting changes during detailed design and procurement and update the PSS/E and PSCAD models to match.
• Coordinate with manufacturers and the engineering, procurement and construction (EPC) contractor so plant controller, inverter and protection settings stay consistent with the models PJM studied.
• Prepare the model package for a Necessary Study when you plan a modification under the GIA, so PJM can determine whether it has a permanent material impact on the Transmission System.

Stage 4: Initial Operation, Commercial Operation and As-Built Data

• Update the PSS/E (library and user-defined) and PSCAD models to as-built design parameters and the settings after commissioning, and include in the as-built package the Factory Acceptance Test report you provide for each main power transformer.
• Prepare the as-built electrical modeling data that the GIA requires within one month following commercial operation.
• Perform the as-built PSCAD Model Quality Tests and PSCAD-PSS/E benchmark and prepare the Parameter Verification Report where PJM's EMT guidelines require them.
• Compare commissioning settings with the studied model and flag any difference that PJM may treat as a qualified change to review before commercial operation.
• Prepare the reactive capability curves PJM requires before commercial operation and, where the facility meets the testing criteria in Manual 14D Attachment E, support the reactive capability test due within 90 days after commercial operation.

Stage 5: Post-Commercial Operation Model Tuning and Necessary Studies

• Tune the models against field test results in accordance with North American Electric Reliability Corporation (NERC) MOD-026-2, for submission no later than one year after commercial operation; MOD-026-2 took effect April 1, 2026 and replaced MOD-026-1 and MOD-027-1.
• Update models after any change to inverter-based resource control settings or equipment, the addition of energy storage to a wind or solar facility, or an operation mode conversion, and prepare the full revised deliverables with a change report for the Necessary Study or Surplus request.
• Support the periodic reactive capability tests Manual 14D requires.
