The PJM Board of Managers has authorized changes to the Regional Transmission Expansion Plan (RTEP) to help ensure the most efficient, economical and reliable supply of power for the 65 million people PJM serves across 13 states and the District of Columbia.
The updates include two new baseline projects for reliability:
- Work to solve voltage and thermal violations in the BGE, PEPCO, Met Ed, PPL, PECO, APS and Dominion transmission zones caused by the deactivation of Brandon Shores 1 and 2 coal units in the BGE Zone. This includes building new substations and upgrading and expanding others, building and expanding 500 kV transmission lines, installing and reconductoring 230 kV lines, and installing capacitors.
- New and extended transmission lines to address baseline load growth deliverability and reliability in the Dominion Zone
Baseline reliability transmission enhancement costs are allocated to PJM load.
The Board agreed to remove from the RTEP a previously identified baseline transformer project as a result of a canceled project in the BGE Zone that no longer poses a reliability violation.
The Board also approved baseline scope and cost changes to the State Agreement Approach with New Jersey.
The New Jersey Board of Public Utilities is using PJM’s RTEP process to select and build onshore transmission solutions that will enable the state to meet its goal of injecting 7,500 MW of offshore wind capacity by 2035.
The RTEP changes include a new baseline project costing less than $5 million in the ATSI Zone, where FirstEnergy is performing necessary substation work associated with the deactivation of coal-fired units 5, 6 and 7 at the W.H. Sammis Power Station in Stratton, Ohio.
Three baseline project scope/cost changes less than $5 million also are included:
- Changes to the multi-driver project in the AEP Zone addressing baseline load growth deliverability and reliability as well as congestion relief.
- Canceled solution components deemed no longer needed for operational performance at Artificial Island in the PSEG Zone.
- In the DLCO Zone, FirstEnergy is performing work associated with the existing baseline project with Duquesne Light in response to the deactivation of Cheswick Generating Station Unit 1 in Springdale, Pennsylvania.

How PJM Plans for the Future
PJM’s 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 recommendations to the Board.
