PJM Board Approves Latest RTEP Updates


The PJM Board of Managers approved the latest updates to PJM’s Regional Transmission Expansion Plan, or RTEP, on July 13, 2022.

PJM’s RTEP process helps to ensure the reliability of the power grid for 65 million people. The RTEP updates approve baseline reliability projects, revise the scope of one project and cancel a number of earlier approved projects for an overall RTEP baseline net increase of $82.09 million.

Baseline Reliability Projects

Baseline reliability projects costing more than $10 million are listed below:

  • In the Metropolitan Edison, or Met-Ed, service area, a project will include the installation of a new 300 MVA 230/115 kV transformer at the existing PPL Williams Grove substation and the construction of a new 3.4 mile 115 kV single-circuit transmission line from Williams Grove to Allen substation, among other improvements to resolve voltage magnitude and voltage drop violations.
  • In the Public Service Electric & Gas Company, or PSE&G, service area, a project will replace an aging Athenia 230/138 kV transformer to meet system needs, based on FERC 715 Planning Criteria.
  • In the PSE&G service area, a project will replace the aging Lawrence switching station 230/69 kV transformer and its associated circuit switchers with a larger capacity transformer and equipment to meet system needs, based on FERC Form 715 planning criteria.

Project Changes

In the Jersey Central Power & Light, or JCP&L, service area, the PJM Board approved three baseline project cancellations and one baseline project modification for cost and scope within the Monmouth County Reliability Project, driven by FERC 715 planning criteria. As a result, four Atlantic 34.5 kV breakers will be replaced with 63 kA breakers, and six Werner 34.5 kV breakers will be replaced with 40 kA breakers.

RTEP analysis identifies system violations to reliability criteria and standards, 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. Details of all approved projects are contained in the Transmission Expansion Advisory Committee recommendations (PDF) to the PJM Board.
