The regional operator of the power grid has approved more than $1.5 billion in new electric transmission projects, but the bulk of the spending will occur in upgrades in the franchise territory of Public Service Electric & Gas.
The authorizations include several large and midsize projects that address reliability issues in multiple areas, according to PJM Interconnection officials. The largest project, involving a planned expenditure of $739 million, is designed to deal with aging infrastructure in Burlington, Mercer, and Middlesex counties, requiring a rebuilding of portions of existing transmission lines.
