Silver Run Expansion Project
Silver Run Expansion Project
The Silver Run Expansion project will add new submarine cables adjacent to the existing cables currently in service beneath the Delaware River. These additional cables will enable the transmission line between the Silver Run substation in Delaware and the Hope Creek substation in New Jersey to accommodate additional electrical flows from future renewable projects expected to be in service by the end of the decade. New transition structures will be installed at the termination points of the new submarine cable in order to connect this new cable to the existing overhead transmission line. Equipment at Silver Run substation will also be upgraded as required to serve the additional line capacity.
As part of PJM’s (the electrical grid operator in the Mid-Atlantic region) 2021 State Agreement Approach Proposal Window in response to New Jersey’s offshore wind transmission objectives, an electrical grid reliability need was identified related to certain existing Silver Run Electric facilities. Under certain conditions, the existing Silver Run submarine cables are projected to be overloaded due to future offshore wind generation. The project’s additional submarine cables will address this reliability need by increasing the capacity of the transmission path.
The Silver Run Expansion Project is currently underway with design and permitting efforts. Construction is expected to begin as soon as 2025 with energization of all new project facilities planned for completion by 2029.
