Stakeholders Endorse Expanded Dual Fuel Manual Definition

The Planning Committee endorsed by acclamation manual revisions to reflect FERC’s granting of a PJM proposal to expand the definition of dual fuel gas generation to include configurations where fuel is stored offsite but can be directly supplied by a dedicated pipeline (ER25-3413). (See “Reworked Dual-fuel Definition Endorsed,” PJM MRC/MC Briefs: July 23, 2025.)

The revisions to Manual 21B: PJM Rules and Procedures for Determination of Generating Capability require that dual fuel resources with off-site storage be “similarly situated and comparable to the existing classes of dual fuel gas-fired resources.”

Supplemental Projects

Dominion presented a need to replace 229 structures on four lines due to deterioration of bracing, crossarms and insulators. About 30.2 miles of steel towers and H-frames were installed in 1979 and serve 54 MW of load and 50 MW of solar capacity. The towers are along the Lanexa-Harmony Village 230-kV line and the Lanexa-Goalder’s Creek, Goalder’s Creek-Owl Trap and Owl Trap-Harmony Village 115-kV lines.

The utility presented a $35 million project to serve a 100-MW industrial load in Goochland County by constructing a 230-kV substation, named West Creek, along the Rockville-Short Pump 230-kV line. The double circuit line would be expanded by 6.5 miles to the new substation. The project is in the planning phase with a projected in-service date of July 26, 2028.

Dominion presented a $32 million project to serve a 300-MW data center in Culpeper County by constructing a 230-kV substation, named Shaw, along the Kyser-Remington line. The project is in the planning phase with a projected in-service date of May 1, 2028.

Dominion presented a $21 million project to serve a 176-MW data center in Louisa County with a new 230-kV substation, named Frances, adjacent to the Southall substation and connected by a new double circuit 230-kV line. The project is in the planning phase with a projected in-service date of Aug. 1, 2027.

A $12 million Dominion project would resolve a 300-MW load drop violation associated with the construction of the Frances substation by rebuilding 1.1 miles of the Southall-North Anna 230-kV line, which would pass through Frances, and expand North Anna with new 230-kV breakers at the line’s termination. The only alternative considered was a new 230-kV source from the Gordonsville substation 30 miles away. The project is in the planning phase with a projected in-service date of Dec. 30, 2028.

A $21 million project from Dominion would serve a 292-MW data center in Louisa County with a 230-kV new substation, named Wesbey Drive, adjacent to the Foxbrook Lane substation. It is in the planning phase with a March 1, 2029, in-service date.

FirstEnergy presented a need in the JCPL zone to address the possibility of the Manchester substation being forced offline if the Cookstown-Larrabee-Whitings 230-kV line is interrupted or there is a fault on a remote end breaker. The substation serves about 7,000 customers with 23 MW.
