PJM Board Approves Regional Transmission Enhancement Plan Updates


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 PJM Board on Oct. 3 approved three reliability projects in total that will:

  • Adjust relay settings at the Riverton substation on the Riverton-Bethel Tap 138 kV line to mitigate issues related to the 2025 deactivation notice of Brandon Shores 1 and 2 coal units in the APS zone.
  • Remove the 345 kV and 230 kV generator lead lines at the recently deactivated, coal-fired Homer City Generating Station and install new station service supply and separate AC station service, separate protection and controls schemes, and review and adjust relay protection settings.
  • Install a series reactor at Springdale substation on the Cheswick-Springdale 138 kV line in the APS zone.

Baseline reliability transmission enhancements costs are allocated to PJM load.

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 submission of recommendations to the PJM Board of Managers.
