Wildwood to Riverhead

The Wildwood to Riverbend project involves about 10.6 miles of 69-kV to 138-kV uprgrade. The line will be upgraded by installing insulators capable of supporting 138-kV transmission. Several poles at the Wildwood Substation will be added to the existing right of way. Existing conductors will not be replaced. A short piece (300’) of underground 138-kV cable will be installed near the Wildwood Substation to transition the overhead line into the Wildwood Substation. The project is estimated to cost about $6 million.
