PSEG Long Island to Upgrade Substations in East Shoreham, Riverside

Dec. 16, 2020
Work will help ensure sufficient capacity for the future power needs of the East End.

PSEG Long Island will be performing necessary upgrades to the transmission infrastructure that connects substations on the eastern end of Long Island in order to accommodate the growing demand in the area.

Over the next few months, crews will be upgrading equipment at two substations in East Shoreham and Riverside as part of a project called the Wildwood to Riverhead Conversion Project.

Project specifics

PSEG Long Island will upgrade equipment in both the Wildwood Substation in East Shoreham and the Riverhead Substation in Riverside to carry 138 kV of electricity, compared with the existing 69-kV equipment in place. The substation activities will occur within the existing footprints of both facilities.

In the existing transmission corridor adjacent to the Wildwood Substation, three existing transmission poles will be removed and replaced with three new riser poles of similar size and height. Also, 900 ft of 138-kV underground transmission line will be constructed from the substation to just east of the LILCO Road. The underground cable will replace the overhead wire where the three existing poles are to be removed. The three new riser poles will provide a transition from overhead to underground.

At the Riverhead Substation, one transmission pole will be removed and insulators replaced on one other pole to allow the wires to carry 138 kV of electricity.

Crews will use overhead bucket trucks to complete the overhead portions of the work, excavation equipment for the trenching of the underground portion, and use approved access ways within the corridor or adjacent to it.

The upgrades will ensure customers receive safe, reliable electric power for years to come. There will not be any outages or traffic disruptions related to this project.

Project location

The areas of work for this portion of the project are the Wildwood Substation, located in East Shoreham; the existing LIPA transmission corridor that travels east from the Wildwood Substation to Randall Road, which will be the extent of the new underground transmission cable trenching; and the Riverhead Substation in Riverside.

Other details

Work is expected to begin in January 2021 and be completed in June 2021. Crews are scheduled to work generally Monday through Friday, 7 a.m. to 6 p.m., with some Saturdays during daylight hours.

There will be no tree trimming associated with this work. However, there will be mowing and brush removal within the corridor to allow access to the existing structures.

PSEG Long Island has received permission under New York State Public Service Commission Article VII law to perform all work associated with the project.
