PJM Board Authorizes Additions to RTEP to Improve Reliability and Relieve Congestion


PJM’s 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.

At its Dec. 4 meeting, the Board authorized nearly $134 million in additional electric transmission system upgrades to meet PJM reliability and deliverability criteria, and transmission owner reliability criteria. Details of the approved changes are posted on pjm.com and highlighted below.

Of the $134 million of the new recommended baseline transmission enhancements, the largest are:

  • $58.6 million to rebuild 20 miles of the East Towanda-North Meshoppen 115 kV line and adjusting relay settings in the Penelec Transmission Zone in Pennsylvania
  • $24.7 million for an Interregional Market Efficiency Project to rebuild the Michigan City-Trail Creek-Bosserman 138 kV line in MISO’s Northern Indiana Public Service Company (NIPSCO) Transmission Zone in Indiana
  • $22 million to create a line terminal at Belle Haven Delivery Point and install a new single-circuit 69 kV, 21-mile line from Kellam substation to new Bayview substation in the ODEC Transmission Zone in Virginia

A key dimension of PJM’s RTEP process is baseline reliability evaluation. Baseline analysis identifies system violations to reliability criteria standards.

Reconfiguration of Project 9A

In ongoing siting proceedings before the Maryland Public Service Commission and the Pennsylvania Public Utility Commission, several parties have filed a settlement relating to the Transource Independence Energy Connection project, commonly referred to as Project 9A. 

This settlement, if approved, would modify the eastern portion of Project 9A to use and expand existing right of way. The Board approved this Alternative Project 9A subject to the Maryland Public Service Commission’s and the Pennsylvania Public Utility Commission’s approval of it through their respective Certificate of Public Convenience and Necessity proceedings.

Details about the reconfigured project are posted on pjm.com with the agenda of the Dec. 12 Transmission Expansion Advisory Committee meeting.

How PJM Plans for the Future

PJM uses an open process to plan for changes to the electric grid in the 13-state region to maintain future reliability and economic performance of the grid. PJM’s process looks ahead 15 years, assessing many drivers that affect grid reliability. PJM studies many scenarios and analyzes various grid conditions that could lead to problems in the way power flows throughout the region.

When PJM identifies potential problems, it works with transmission owners and other members through a competitive planning process to determine the best solution for the problem, meeting required national standards.

The RTEP process determines the needs for the regional transmission system and the enhancements to meet those needs. It does not review or approve locations where transmission lines are ultimately built. That is the responsibility of individual states.

All transmission improvements identified through this process are discussed publicly in stakeholder meetings, and reviewed and approved by the PJM Board before being included in PJM’s expansion plan.
