Preface
The intent of the System Impact 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 the Interconnection Customer. As a requirement for interconnection, the Interconnection Customer may be responsible for the cost of constructing: Network Upgrades, which are facility additions, or upgrades to existing facilities, that are needed to maintain the reliability of the PJM system. All facilities required for interconnection of a generation interconnection project must be designed to meet the technical specifications (on PJM web site) for the appropriate transmission owner.
In some instances an Interconnection Customer may not be responsible for 100% of the identified network upgrade cost because other transmission network uses, e.g. another generation interconnection or merchant transmission upgrade, may also contribute to the need for the same network reinforcement. The possibility of sharing the reinforcement costs with other projects may be identified in the Feasibility Study, but the actual allocation will be deferred until the System Impact Study is performed.
The System Impact study estimates do not include the feasibility, cost, or time required to obtain property rights and permits for construction of the required facilities. The project developer is responsible for the right of way, real estate, and construction permit issues. For properties currently owned by Transmission Owners, the costs may be included in the study.
An Interconnection Customer with a proposed new Customer Facility that has a Maximum Facility Output equal to or greater than 100 MW shall install and maintain, at its expense, phasor measurement units (PMUs). See Section 8.5.3 of Appendix 2 to the Interconnection Service Agreement as well as section 4.3 of PJM Manual 14D for additional information.
General
The Interconnection Customer (IC), has proposed a generating facility located in Lasalle County, Illinois. The installed facilities will have a total capability of 150.0 MW with 26.4 MW of this output being recognized by PJM as Capacity. The proposed in-service date for this project is Friday, December 31, 2021. This study does not imply a TO commitment to this in-service date.

Cost Summary
The project may be responsible for a contribution to the following costs:
| Description | Total Cost |
|---|---|
| Attachment Facilities | $1,127,464 |
| Direct Connect Facilities | $31,267,455 |
| Non-Direct Connect Facilities | $45,887,293 |
| Physical Interconnection | $0 |
| System Reinforcements | $7,957,585 |
Note 1: PJM Open Access Transmission Tariff (OATT) section 217.3A outline cost allocation rules. The rules are further clarified in PJM Manual 14A Attachment B. The allocation of costs for a network upgrade will start with the first Queue project to cause the need for the upgrade. Later queue projects will receive cost allocation contingent on their contribution to the violation and are allocated to the queues that have not closed less than 5 years following the execution of the first Interconnection Service Agreement which identifies the need for this upgrade.
Note 2: For customers with System Reinforcements listed: If your present cost allocation to a System Reinforcement indicates $0, then please be aware that as changes to the interconnection process occur, such as prior queued projects withdrawing from the queue, reducing in size, etc, the cost responsibilities can change and a cost allocation may be assigned to your project. In addition, although your present cost allocation to a System Reinforcement is presently $0, your project may need this system reinforcement completed to be deliverable to the PJM system. If your project comes into service prior to completion of the system reinforcement, an interim deliverability study for your project will be required.
Transmission Owner Scope of Work
Attachment Facilities
The total preliminary cost estimate for the attachment work is given in the table. These costs do not include CIAC Tax Gross-up.
The IC AD2-038 generator lead will interconnect to a new 345kV Interconnection Substation. This interconnection would require one 345kV line MOD, a dead-end structure and revenue metering as shown in the one-line diagram.
Direct Connection Cost Estimate
The total preliminary cost estimate for the Direct Connection work is given in the table. These costs do not include CIAC Tax Gross-up.
To accommodate interconnection of AD2-038, a new 345kV Interconnection Substation would be built looping in the 345kV line 0303 between Powerton Station 3 and the proposed Nevada TSS 98 (to be built under PJM queue AA1-018), to interconnect IC’s generator lead line.
The scope of work includes installation of three 345kV circuit breakers in “breaker-and-a-half” bus configuration and tie in the Interconnection Substation to the 345kV line 0303 between Powerton Station 3 and the proposed Nevada TSS 98 (to be built under PJM queue AA1-018), as shown in the one-line diagram below.
The Interconnection Customer is responsible for constructing all the facilities on the Interconnection Customer side of the point of interconnection outside of the Interconnection Substation. It is assumed for the purposes of this report that the IC will obtain the site for the Interconnection Substation and right-of-way between the Interconnection Substation and the 345kV transmission line.
In the event, that the IC exercises the option to build the interconnecting substation, the IC will be required to construct all interconnection facilities that will be turned over to ComEd in accordance with ComEd published standards and PJM Tariff.
ComEd would design, engineer and construct the tie in of the Interconnection Substation to 345kV line 0303. There are two 345kV lines 1227 and 1202 between the proposed Interconnection Substation and line 0303. Accordingly, this tie-in would require raising these two 345kV lines for line crossing. The estimated cost for Direct Connection Network Upgrade is given below.
Non-Direct Connection Cost Estimate
The integration of the new 345kV Interconnection Substation would require relay/communications/SCADA upgrades at the Powerton Station 3 and Nevada TSS 98.
The total preliminary cost estimate is given in the table below. These costs do not include CIAC Tax Gross-up.

$4,548,144 |
| n8189.6 | Fiber Installation Between Sta 3 and ComEd Existing Fiber (~42 miles) |
$30,581,932 |
Based on the scope of work for the interconnection facilities, it is expected to take a range of 36 to 37 month(s) after the signing of an Interconnection Agreement (as this is a non-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.
The schedule for any required Network Impact Reinforcements will be more clearly identified in future study phases. The estimated time to complete each of the required reinforcements is identified in the "System Reinforcements" section of the report.
Notes on Cost Estimate:
- These estimates are Order-of-Magnitude estimates of the costs that ComEd would bill to the customer for this interconnection. These estimates are based on a one-line electrical diagram of the project and the information provided by the IC.
- There were no site visits performed for these estimates. There may be costs related to specific site related issues that are not identified in these estimates. The site reviews will be performed during the Facilities Study or during detailed engineering.
- These estimates are not a guarantee of the maximum amount payable by the IC and the actual costs of ComEd's work may differ significantly from these estimates. The IC will be responsible for paying actual costs of ComEd's work in accordance with Sections 212.1 and 217 of the PJM Open Access Transmission Tariff.
- The IC is responsible for all engineering, procurement, testing and construction of all equipment on the IC’s side of the POI.
- These cost estimates do not include cost of acquiring right-of-way for the transmission line and purchasing any additional land, if needed, for the line terminations. The need and cost of acquiring property and associated legal costs will be investigated during Facilities Study for this project.

Light Load Potential Congestion due to Local Energy Deliverability
PJM also studied the delivery of the energy portion of this interconnection request. Any problems identified below are likely to result in operational restrictions to the project under study. The developer can proceed with network upgrades to eliminate the operational restriction at their discretion by submitting a Merchant Transmission Interconnection request.
Note: Only the most severely overloaded conditions are listed below. There is no guarantee of full delivery of energy for this project by fixing only the conditions listed in this section. With a Transmission Interconnection Request, a subsequent analysis will be performed which shall study all overload conditions associated with the overloaded element(s) identified.
(No impacts were found for this analysis)
Short Circuit Analysis
This project does not cause any circuit breakers to exceed their interrupting capability.
Stability Analysis
No mitigation was found to be required due to transient stability.
Reactive Power Analysis
Reactive deficiency identified, see attached stability study report for details
Steady-State Voltage Analysis
Steady State Voltage analysis is not required for this queue project at this time.
Queue Dependencies
The Queue Projects below are listed in one or more dispatch for the overloads identified in your report. These projects contribute to the loading of the overloaded facilities identified in your report. The percent overload of a facility and cost allocation you may have towards a particular reinforcement could vary depending on the action of these earlier projects. The status of each project at the time of the analysis is presented in the table. This list may change as earlier projects withdraw or modify their requests. This table is valid for load flow analyses only.

* = Queue Project is after AD2-038 in queue order. Withdrawal of this project is unlikely to affect cost allocation for AD2-038.
Affected Systems
System Reinforcements
| RTEP ID | Title | Total Cost | Time Estimate |
|---|---|---|---|
| n4058 | Sag Mitigation Work on the Stillwell - Dumont 345 kV line | $1,971,000 | 12 - 13 Months |
Note: Based on PJM cost allocation criteria, AD2-038 currently does not receive cost allocation towards this upgrade. As changes to the PJM queue process occur (such as prior queued projects withdrawing from the queue, reducing in size, etc.) AD2-038 could receive cost allocation. Although Queue Project AD2-038 may not presently have cost responsibility for this upgrade, Queue Project AD2-038 may need this upgrade in-service to be deliverable to the PJM system. If Queue Project AD2-038 comes into service prior to completion of the upgrade, Queue Project AD2-038 will need an interim study.
Description: A sag study was performed on this section of conductor. The following reinforcements were identified by the sag study and will be required to mitigate the overload: AEP will replace structure #20 with a single circuit custom steel pole structure and structure #24 with a custom steel H-frame structure on the Stillwell - Dumont 345 kV circuit. The replacements include removal of the two (2) existing lattice structures. AEP will also modify one (1) existing lattice structure, replacing a bottom swing angle bracket with a 3” tee. SE rating will be 1718 MVA limited by a Dumont wave trap. (Provided by AEP per AD1-098 FAC study).

| n5145 | Reconfigure Wilton 765kV bus | $55,229,373 | 36 - 40 Months |
AD2-038 is a Contributor.
Description: Reconfigure Wilton 765kV bus thereby allowing for 765kV L11216 (currently on Bus 6) to be relocated to Bus 8. Along with this line relocation, installation of 2-765kV BT CBs (6-8 & 8-2). Cost increased from $12M to $55M. This will eliminate the stuck breaker contingencies '112-65-BT4-5__' and '112-65-BT5-6__'. No other contingency updates needed.
