PJM Board Approves RTEP Updates

2194

The PJM Board of Managers on April 22 approved the latest changes to PJM’s Regional Transmission Expansion Plan, or RTEP, to ensure the reliability of the power grid for 65 million people.

The updates include several baseline reliability projects, changes to scope and cost of existing projects, and the cancellation of a project.

The baseline projects approved by the PJM Board include:

  • In the AEP transmission zone, building 9.4 miles of single circuit 69 kV line from Roselms to near East Ottoville 69 kV Switch and rebuilding 7.5 miles of double circuit 69 kV line between East Ottoville switch and Kalida station.
  • In the AEP transmission zone, rebuilding the approximately 10-mile-long Chatfield-Melmore 138 kV line.
  • In the AEP transmission zone, constructing approximately 2.75 miles of new 69 kV transmission lines from Orinoco to Stone substations, and approximately 3.25 miles of new 69 kV transmission lines from Orinoco to New Camp substations.
  • In the Dominion transmission zone, building a new 230 kV switching station (Walnut Creek) and operating it at 115 kV at the junction where both Fork Union-Sherwood and Dooms-Sherwood 115 kV lines start to share a common structure.

RTEP analysis identifies system violations to reliability criteria and standards and associated solutions to mitigate the violations, determines the potential to improve the market efficiency and operational performance of the system, and incorporates any public policy requirements.

PJM then develops transmission system enhancements to be integrated into a regional solution set and reviews them with stakeholders through the Transmission Expansion Advisory Committee (TEAC) before submitting its recommendation to the Board. Baseline reliability transmission enhancement costs are allocated to PJM load.

The PJM Board also approved the cancellation of a project to rebuild the 138 kV Moseley-Roanoke line in the AEP transmission zone. The project was put on hold back in 2014, and no reliability violations have been identified in any RTEP cycle since then.

Details of all approved projects are contained in the Transmission Expansion Advisory Committee recommendations to the PJM Board. Follow all projects through the process with PJM’s Project Status & Cost Allocation tool.
