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 the Crete-to-St. John area improvement project in Illinois, from PJM’s first multi-driver window since the inception of the Federal Energy Regulatory Commission’s Order 1000 competitive planning process. This effort identified the need for a holistically planned transmission solution that considered both reliability and market efficiency benefits and also optimized end-of-life facility rebuilds in the area.
In addition to this improvement and transmission upgrades to solve baseline reliability criteria violations, the Board agreed to cancel a previously identified baseline upgrade as a result of updates to the analysis performed.

Baseline Reliability Projects
Approved baseline reliability projects costing more than $10 million are listed below:
- Construction to avoid overload on the College Corner-Collinsville 138 kV line in the APS and Dayton transmission zones
- Rebuilding the Breaks-Dorton 69 kV line in the AEP transmission zone
- Replacing the Jug Street 138 kV breakers in the AEP transmission zone
- Reconductoring/replacement on the Messick Road-Morgan 138 kV line in the APS transmission zone
- Reconductoring two 230 kV circuits from Conastone to North West No. 2 in the BGE transmission zone
- Reconductoring line No. 23 of the Bell Avenue-Suffolk 115 kV line in the Dominion transmission zone
- Rebuilding the New Church-Piney Grove 138 kV line in the DPL transmission zone
- Rebuilding/reconductoring the Lincoln-Germantown 115 kV line in the MetEd transmission zone
- Installing a second Three Mile Island 500/230 kV transformer with additional 500 and 230 bus expansions in the MetEd transmission zone
- Rebuilding the Roxbury-AE1-071 115 kV line in the PENELEC transmission zone
- Rebuilding the Shade Gap-AE1-071 115 kV line in the PENELEC transmission zone
- Constructing a new three-breaker ring bus at McLane tap to tie into the Warrior Ridge-Belleville 46 kV D line and the 1LK line in the PENELEC transmission zone
- Converting the Locust Street 69 kV station from a straight bus to a ring bus in the PSEG transmission zone
- Converting the Maple Shade 69 kV station from a straight bus to a ring bus in the PSEG transmission zone
- Constructing a new 69 kV line from 14th Street to Harts Lane in the PSEG transmission zone
Baseline reliability transmission enhancement costs are allocated to PJM load.
The PJM Board also approved several projects with individual cost estimates of less than $10 million, including a 40 kV breaker replacement, cap bank installations, terminal limiting equipment replacements, conductor replacements and relay upgrades.
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 recommendation to the Board.
Details of all approved projects are contained in the Transmission Expansion Advisory Committee recommendations (PDF) to the PJM Board. Follow all projects through the process with PJM’s Project Status & Cost Allocation tool.
