The PJM Interconnection Board of Managers has authorized changes to existing projects in the Regional Transmission Expansion Plan (RTEP) as well as transmission system improvements to help provide the most efficient, economical and reliable supply of power for the 67 million people PJM serves across 13 states and the District of Columbia.
Approved on Nov. 18 were several scope-and-cost changes to previously approved baseline projects, one project cancellation and baseline projects consisting of various substation equipment upgrades supporting and paid for by new generation resources.
PJM said that throughout 2025, the overseer of much of the East Coast’s transmission grid has request and include an evaluation of new generation interconnections, increases in generation at existing stations, long-term firm transmission service requests and merchant transmission interconnection requests.
These studies were last reviewed with the Board Reliability and Security Committee in February 2025. Since that time, PJM has completed 398 system impact studies, and 522 new service requests have been withdrawn. New projects with signed interconnection service agreements (ISAs), project scope changes and project cancellations have resulted in a net increase of $604.4 million for network upgrades.Â
The original baseline project scope for b3869 was to remove/retire the two Bergen 138 kV series reactors and relocate the Bergen generator No. 1 Point of Interconnection from Bergen 138 kV to Bergen 345 kV GIS through the existing 345/138 kV transformer. PSE&G’s FERC Form 715 criteria did not allow it to buy a spare reactor, which is why the original scope was recommended.
However, PSE&G has since changed its FERC Form 715 criteria to allow for the purchase of the spare reactor. The new scope is to replace the two Bergen 138 kV series reactors with two new 138 kV series reactors.
The project scope change results in the cost estimate increasing from $12.5 million to $12.8 million.
