The Project: Converter Stations

Sayreville Fac crop

Reliable Electric Supply for long Island


Neptune’s two converter stations, which are virtually identical, were built under the direction of Siemens and employ Siemens power conversion technology. The converter stations require no fuel or combustion, and produce no air emissions or discharges of pollutants. They meet all local and state codes and standards for noise, visual impacts, public safety, and electro-magnetic fields.

The stations are comprised of three connected buildings, the tallest of which is about 64 feet high (similar to a 5-6 story building), and outside filter banks, similar to a standard electrical substation.

Duffy Avenue Converter Station Site (June 2007)

The Duffy Avenue converter station is located on a 12-acre parcel of land in an industrial/commercial area adjacent to the Wantagh State Parkway. The site is shared by a New York State Department of Transportation maintenance facility, and is owned by the New York State Office of Parks, Recreation and Historic Preservation (OPRHP).  The Company executed a Master Agreement with OPRHP that encompasses both the use of the Wantagh State Parkway right-of-way for installing the land portion of the cables as well as the Duffy Avenue parcel for the converter station.

The Sayreville converter station is located on a parcel of land acquired from the Borough of Sayreville Economic & Redevelopment Agency on River Road.  The Sayreville converter station is adjacent to and connects via approximately 2,500 feet of AC cable to the existing First Energy substation, located at the northern end of the Reliant Energy Generating Station site adjacent to River Road
