Introduction

This Phase I System Impact Study Report (PH1) has been prepared in accordance with the PJM Open Access Transmission Tariff, Part VII, Subpart D, sections 307 and 308 for New Service Requests (projects) in Transition Cycle #1. The Project Developer/Eligible Customer (developer) is Dolphin Solar LLC, and the Transmission Provider (TP) is PJM Interconnection, LLC (PJM). The interconnected Transmission Owner (TO) is American Electric Power.

Preface

The Phase I System Impact Study is conducted on an aggregate basis within a New Services Request’s Cycle, and results are provided in both (i) a single Cycle executive summary format and (ii) an individual project-level basis. The Phase I System Impact Study Results (for both the executive summary and individual reports) will be publicly available on PJM’s website. Developers must obtain the results from the website.

In accordance with PJM Manual 14H, section 4.3, PJM takes the following actions during the Phase I System Impact Study:
  1. PJM studies each New Service Request on a summer peak, winter peak[1] and light load RTEP base case study. The case year is dependent on the new services cycle under study. PJM will identify the base case year to be used in the study of a specific cycle on its website.
  2. PJM will only perform load flow analysis during the Phase I System Impact Study.
  3. In Phase I of the Cycle, PJM conducts an Affected System screen to identify any New Service Request with Affected System impacts and provides each Affected System Operator with a list of New Service Request in the Cycle with potential impacts to their respective system.
  4. PJM will create both the short circuit and stability base cases to be used in the Phase II System Impact Study.
  5. The Phase I System Impact Study results will be publicly available on PJM’s website. Project Developers and Eligible Customers must obtain the results from the website.
The Transmission Owner takes the following actions during the Phase I System Impact Study:
  1. Identify required Interconnection Facilities to accommodate the New Service Request.
  2. Identify required Network Upgrades to mitigate system violations from the Phase I System Impact Study.
  3. Provide planning-level preliminary estimates of Interconnection Facilities and Network Upgrades including scope, cost and elapsed time to complete the work.

Decision Point I Requirements

At the close of Phase I System Impact Study, PJM will initiate Decision Point I (DP1). During DP1, the Project Developer will have 30 days to decide whether to proceed with their project. If the Project Developer elects to proceed, they should provide the elements defined in the PJM Open Access Transmission Tariff, Part VII, Subpart D, section 309.A.1. Additional information on these elements is available in PJM Manual 14H sections 4.4, 6, and 7.

Allowable project modifications at Decision Point I are defined in PJM Open Access Transmission Tariff, Part VII, Subpart D, section 309.B. Additional information regarding allowable project modifications can be found in PJM Manual 14H, section 9.8.

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.

Readiness Deposit

Per Tariff Part VII, Subpart D, section 309 (Decision Point I) A.1.a.i and PJM Manual 14H, section 6.2, Readiness Deposit #2 (RD2) are funds committed by the Project Developer or Eligible Customer based upon the applicable contribution to Network Upgrades as defined below and not used to fund studies nor to offset Security.

During Decision Point I (DP1), the Project Developer or Eligible Customer is required to submit Readiness Deposit #2, which is calculated as 10% of cost allocation for required Phase I Network Upgrades minus Readiness Deposit #1.

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 can be zero, but may not be a negative number.

Readiness Deposit #2 Due for Project AG1-226

Readiness Deposit #2 has been calculated for the project based on the Phase I System Impact Study results and is shown in the table below. This Readiness Deposit #2 must be provided at Decision Point I through either a wire transfer or letter of credit per Manual 14H, Section 6.2.

Readiness Deposit
Project ID 10% of cost allocation for Phase I Network Upgrades Readiness Deposit #1 Received (RD1) Readiness Deposit #2 (RD2) for AG1-226 Project due at DP1
A B A - B
AG1-226 $2,764,577 $1,800,000 $964,577

Note: Failure to provide an acceptable form of Readiness Deposit #2 by the end of Decision Point I will result in withdrawal and termination of the New Service Request.

Transmission Owner Scope of Work

AG1-226 will interconnect with the AEP transmission system via a new station cut into the Eugene - Dequine 345 kV Circuit. The estimates provided in this report are preliminary in nature, as they were determined without the benefit of detailed engineering studies. Final estimates will require an on-site review and coordination to determine final construction requirements. In addition, Stability analysis will be completed during the Phase 2 study. It is possible that a need for additional upgrades could be identified by these studies.

The total preliminary cost estimate for the Transmission Owner scope of work (including TOIF and Physical Interconnection Network Upgrades) is given in the table below. These costs do not include CIAC Tax Gross-up.

Transmission Owner Interconnection Facilities
RTEP ID Description Total Cost ($USD) Allocated Cost ($USD)
(Pending) AEP will install one (1) new steel, single circuit, single pole dead end structure with associated conductor and shield wire for the generation lead circuit extending from the proposed 345 kV station. $1,610,000 $1,610,000
(Pending) AEP will install a standard revenue metering package for the generation lead circuit at the proposed 345 kV station. $810,000 $810,000
(Pending)
Extension of two (2) fiber optic cables from the proposed 345 kV station control house to fiber demarcation splice boxes to support direct fiber relaying between the proposed 345 kV and Project Developer's collector stations. The Project Developer will be responsible for the fiber extension from the splice boxes to the collector station.
$310,000 $310,000
Stand-Alone Network Upgrades
RTEP ID Description Total Cost ($USD) Allocated Cost ($USD)
(Pending)

$17,900,000 $17,900,000
Network Upgrades
RTEP ID Description Total Cost ($USD) Allocated Cost ($USD)
(Pending)
AEP will install two (2) new, double circuit, single-pole dead-end structures, one (1) new double circuit, single pole, tangent structure, and associated spans of conductor and shield wire in the existing Eugene - Dequine 345 kV Right of Way, cutting in the proposed 345 kV station in an in-and-out arrangement. The additional tangent structure will be installed to prevent blowout from the conductor on the far side of the double circuit tower line into the new dead end structures being installed to accommodate this interconnection.
$2,660,000 $2,660,000
(Pending)
AEP will replace the remote end protective relays at the Eugene and Dequine 345 kV Stations.
$910,000 $910,000

Based on the scope of work for the Interconnection Facilities, it is expected to take a range of 24 to 36 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.

The schedule for any required Network Impact Reinforcements will be more clearly identified in the Phase II and Phase III System Impact Studies.

The minimum and maximum schedules reflect the amount of time, in months, that AEP projects their portion of the construction project scope elapsing from the time of agreement. Final agreements will reflect an "on or before" date, allowing all parties to c, including remote end work, considering the Project Developer selection of the Option To Build, allocating the long lead material ordering as part of the Project Developer scope. The maximum schedule is based off of AEP assumed long lead material ordering not considering allocation of existing material production slots, advanced progress enabled by Engineering and Procurement Agreements, or other schedule expediting methods. AEP may be able to allocate material production slots for long lead time materials to expedite this schedule. Final agreements will reflect an "on or before" date, allowing all parties to complete their scope of work prior to the agreement date, should there be means to expedite. Any material ordering or construction work done prior to Engineering and Procurement or Generation Interconnection Agreements is done solely at the Project Developers risk. There is a potential that any work done or materials ordered prior to these agreements and the ensuing detailed engineering processes does not meet AEP specifications, resulting in rejection of the completed work.

Transmission Owner Analysis

No violations.

 

Developer Requirements

To the extent that these Applicable Technical Requirements and Standards may conflict with the terms and conditions of the Tariff, the Tariff shall control.

AEP posts the latest versions of the "Connection Requirements for the AEP Transmission System", and associated documentation at: https://www.aep.com/requiredpostings/AEPTransmissionStudies

Revenue Metering and SCADA Requirements

PJM Requirements    

 

The Project Developer will be required to install equipment necessary to provide Revenue Metering (KWH, KVARH) and real time data (KW, KVAR) for their generating Resource. See PJM Manuals M-01 and M14D, and PJM Tariff Part IX, Subpart B, Appendix 2, Section 8.

 

Meteorological Data Reporting Requirement             

The solar generation facility shall provide the Transmission Provider with site-specific meteorological data including:

 

    • Temperature (degrees Fahrenheit)
    • Atmospheric Pressure (hectopascals)
    • Irradiance
    • Forced outage data                


Interconnection Transmission Owner Requirements        

The details of applicable metering requirements are provided in the "Connection Requirements for the AEP Transmission System" document, found at: https://www.aep.com/requiredpostings/AEPTransmissionStudies  The primary metering will be installed on the Transmission Owner side of the Point of Change in Ownership and will be owned and maintained by the Transmission Owner. Any additional generation proposed behind an originating project POC that differs in either type or corporate entity from the originating project will require the installation of additional submetering for both the originating project and the uprate for the purpose of settlement. Submetering will require additional space within the originating project facilities. The meters, routers, Ethernet to fiber converters, and telecom switch will be procured and owned by AEP. The revenue quality instrument transformers, fiber cable connecting the submeters, and any other additional hardware for the required submetering will be procured, installed, owned, and maintained by the Project Developer.

Summer Peak Analysis

The New Service Request project was evaluated as a 450.0 MW (Capacity 331.5 MW) injection in the AEP area. Project was evaluated for compliance with applicable reliability planning criteria (PJM, NERC, NERC Regional Reliability Councils, and Transmission Owners). Potential summer peak period network impacts were as follows:

Note: The capacity portion of New Service Requests are evaluated for single or N-1 contingencies. The full energy output of New Service Requests are evaluated for multiple facility contingencies (double circuit tower line, fault with a stuck breaker, and bus fault).

DEI (Pending) / DEI_TC1_13416 MISO end upgrade: Mitigation would be add a new 345kV Circuit in Parallel of existing 345kV line from Cayuga to Eugene. AEP SE rating is 1868 MVA . $12,095,000 $0 TBD

Contingent

Note: Based on PJM cost allocation criteria, AG1-226 currently does not receive cost allocation towards this upgrade. As changes to the PJM process occur (such as other projects withdrawing from the cycle or reducing in size) AG1-226 could receive cost allocation. Although AG1-226 may not presently have cost responsibility for this upgrade, AG1-226 may need this upgrade in-service to be deliverable to the PJM system. If AG1-226 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.
