Generation Interconnection System Impact Study Report for PJM Generation Interconnection System Impact Study Report For PJM Generation Interconnection Request Queue Position AA1-106 Grover II 34.5kV April 2016 Preface The intent of the System Impact Study 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. General IMG Development, LLC, the Interconnection Customer (IC), has proposed a natural gas generating facility located in Tioga County, PA. The installed facilities will have a total capability of 19.9 MW with 19.9 MW of this output being recognized by PJM as capacity. The proposed in-service date for this project is December 2016. This study does not imply a Pennsylvania Electric Company (Penelec) commitment to this in-service date. Attachment facilities and local upgrades (if required) along with terms and conditions to interconnect AA1-106 will be specified in a separate two party Interconnection Agreement (IA) between Penelec and the Interconnection Customer as this project is considered FERC non- jurisdictional per the PJM Open Access Transmission Tariff (OATT). From the transmission system perspective, no network impacts were identified as detailed below. Point of Interconnection AA1-106 will interconnect with the Penelec distribution system along a 34.5kV circuit from the Grover substation. © PJM Interconnection 2016.

Engineering Oversight and Commissioning - FE $ 130,200 $ 39,300 $ 169,500 Construction (No-OTB) - FE-7 Total Attachment Cost Estimate $ 585,100 $ 180,000 $ 765,100 Schedule Based on the scope of the FE direct connection, it is expected to take approximately one (1.0) year from the signing of a Connection Service Agreement to complete the installation required for the AA1-106 Project. This includes a preliminary payment that compensates FE for the first three months of the engineering design work that is related to the construction of a new AA1-106 Interconnecting tap pole and the associated equipment of the Penelec 34.5 kV line to this site. It also assumes that the Interconnection Customer will provide the property for the attachment tap pole and all right-of-way, permits, easements, etc. that will be needed. A further assumption is 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 direct connection and network upgrades, and that FE will allow all distribution system outages when requested. The required network upgrades are estimated to take approximately 18 months to complete. Interconnection Customer Requirements In addition to the FE facilities, the Interconnection Customer will also be responsible for meeting all criteria as specified in the applicable sections of the "FE Requirements for Transmission Connected Facilities" document including: 1. The purchase and installation of the minimum required FE generation interconnection relaying and control facilities. This includes over/under voltage protection, over/under frequency protection, and zero sequence voltage protection relays. © PJM Interconnection 2016. All rights reserved. 4 AA1-106 Grover II 34.5kV 2. The installation of a Penelec provided 34.5 kV interconnection metering instrument transformer. FE will provide the ratio and accuracy specifications based on the customer load and generation levels. 3. The installation of a Penelec provided revenue class meter for each unit to measure the power delivered in compliance with the FE standards. 4. The purchase and installation of supervisory control and data acquisition (SCADA) equipment to provide information in a compatible format to the FE Transmission System Control Center. 5. The establishment of dedicated communication circuits for SCADA report to the FE Transmission System Control Center. 6. A compliance with the FE and PJM generator power factor and voltage control requirements. 7. The execution of a back-up service agreement with the electric distribution company to serve the customer load supplied from the AA1-106 generation project interconnection point when the units are out-of-service. This assumes the intent of the Interconnection Customer is to net the generation with the load. 8. The rough grade of the property for the AA1-106 Interconnection 34.5 kV tap pole and an access road for the delivery of equipment to this site. The above requirements are in addition to any metering and telecommunications required by PJM as specified in PJM Manuals M-01 and M-14D System Protection Analysis An analysis was conducted to assess the impact of the Grover II (AA1-106) Project on the system protection requirements in the area. The results of this review show that the following relay additions will be required: Proposed single line diagrams show the Interconnection Customer constructing a generation facility they call “Pine Hill” tapping Penelec’s 34.5kV Grover - Canton circuit at pole 3U998. The 34.5kV interconnection proposal will require the Interconnection Customer to meet applicable "Technical Requirements" as outlined in First Energy's document titled “Technical Requirements for the Interconnection of Customer-Owned Generation to the FirstEnergy Distribution System".

  • Testimony of Evelyn Robinson, Managing Partner – State Government Policy PJM Interconnection, L.L.C March 4, 2021
    Before the Indiana Senate Utilities Committee Testimony of Evelyn Robinson, Managing Partner – State Government Policy PJM Interconnection, L.L.C March 4, 2021 For Public Use Testimony of Evelyn Robinson, Managing Partner – State Government Policy Introduction Good day Chairman Koch, Ranking Member Perfect and esteemed members of the Utilities Committee. My name is Evelyn Robinson, and I am the Managing Partner within the State Government Policy Department at PJM Interconnection, L.L.C (“PJM”). Thank you for having me today. I am here before this committee to speak on PJM’s role as a regional transmission organization (“RTO”) and to discuss PJM’s winter preparedness and performance during the recent cold weather event. As an RTO, PJM’s primary focus is the reliable operation of the nation’s largest electric grid for 65 million people in 13 states and Washington, D.C. – including portions of Indiana. As illustrated in Figure 1 of my testimony, our service territory extends from New Jersey to Illinois, encompassing the Indiana/Michigan electric utility portion of the AEP transmission zone. This scale allows us to provide reliable electric service from the Atlantic Ocean to the Mississippi River; from the Great Lakes to the Outer Banks. Figure 1. Map of PJM Footprint Like the Midcontinent Independent System Operator (“MISO”), PJM is situated within what is called the Eastern Interconnection, one of the three major electric grids in the continental United States. As illustrated in Figure 2 below, the Eastern Interconnection, the Western Interconnection and the Texas Interconnection typically operate independent of each other. The Eastern Interconnection extends from the Atlantic coast to the Rocky Mountains and operates as one harmonized machine.

  • News Release
    NEWS RELEASE FOR IMMEDIATE RELEASE PJM Board of Managers Approves Proposal to Address Capacity Market Reform Decision Shows Successful Conclusion in Stakeholder Process (Valley Forge, PA – July 8, 2021) – PJM Interconnection’s Board of Managers has approved a proposal to address long-standing concerns with the Minimum Offer Price Rule (MOPR) in the PJM capacity market. Following presentations on nine proposals from PJM and its stakeholders, the PJM proposal received the highest sector-weighted vote by members. The PJM Board selected the proposal because it accommodates state policy and self-supply business models, addresses attempted exercises of buyer-side market power, and creates a sustainable market design by keeping clearing prices consistent with supply and demand fundamentals. The PJM proposal achieved broad consensus under a unique, accelerated stakeholder process, called the Critical Issue Fast Path (CIFP). This was the first time the PJM Board has employed the CIFP process, an alternative to the normal stakeholder process designed to expeditiously resolve issues that are contentious or time sensitive. “In the first-ever use of the CIFP process, stakeholders have successfully tackled a complex issue in a compressed time frame, achieving both a workable solution and broad consensus behind that solution,” said PJM President and CEO Manu Asthana. “This proposal ensures that our capacity market accommodates state policy and self-supply business models, avoids customer costs of double-procurement, addresses attempted exercises of buyer-side market power, and creates a sustainable market design by keeping clearing prices consistent with supply and demand fundamentals,” Asthana said. PJM expects to work diligently to make a FERC filing with the goal of incorporating the changes into the 2023/2024 Delivery Year Base Residual Auction, to be held in December 2021.

  • Electric Supply – Demand Forecast Report for 2017 – 2026
    Public Service Commission of West Virginia Electric Supply – Demand Forecast Report for 2017 – 2026 Issued February 2017 201 Brooks Street P.O. Box 812 Charleston, WV 25323 1-800-344-5113 Chairman Michael A. Albert Commissioner Brooks F. McCabe, Jr. Commissioner Kara Cunningham Williams 1 Executive Summary The major generation-owning electric utility systems in West Virginia have completed major acquisitions of generation in recent years. At the same time, several older generating facilities have been retired. Cancellation of long-standing capacity agreements with affiliates has occurred, which has contributed to the need for alternative capacity resources. Appalachian Power Company (APCo) and Wheeling Power Company (WPCo) will have marginally adequate capacity for summer requirements in the near future, but will have low reserve margins in the next several years and may have low winter reserve margins during the forecast period. Monongahela Power Company (MPC) and Potomac Edison (PE) also have adequate capacity for summer requirements in the near future, but reserve margins will gradually shrink, becoming negative during the forecast period. If implemented, new EPA standards to limit carbon emissions from existing power plants will affect generation resources. As those standards are proposed, it is likely that generating utilities in West Virginia will need to modify existing generation to meet the EPA goals on both an interim and final basis. Because the timing and extent of rules implementing the EPA standard are unknown at this time, the impacts of any carbon limitations are not included in this report. The Presidential election in November 2016 will likely have a significant impact on the EPA, including how its standards may affect the electric utility and coal industries.
