Brooklyn Avenue Substation
PSEG Long Island is committed to delivering best-in-class system reliability by expanding electrical capacity to meet the needs of the communities we serve, today and in the future. PSEG Long Island’s electric grid consists of three primary elements: electric transmission lines that carry high-voltage power from generation sources; substations that receive the electricity from the transmission lines and step it down to a lower voltage; and distribution lines that carry the lower-voltage electricity into our neighborhoods.
Over the coming months, we will be constructing a new substation on LIPA-owned property at 48 Brooklyn Avenue in Massapequa and connecting distribution infrastructure and an existing transmission line to the new substation in order to meet the growing demand for electricity in the area and to meet the needs of the community.
While this work is being performed, traffic and parking may be impacted along the route. The proposed project consists of several components, including:
- Construction of the new Brooklyn Avenue Substation
- Installation of five new underground 13kV distribution feeders
- Replacement and relocation of three existing steel transmission poles and wires
- Installation of three new steel transmission poles and wires
- Distribution pole replacements and the replacement, removal, and/or installation of pole-top equipment including transformers, switching equipment and electrical wire.
- Installation of underground distribution cable below roadways
- Relocation of an existing water main, which currently bisects the proposed substation property
Recent engineering studies and analysis conducted by PSEG Long Island have concluded that growing energy demands will exceed the capacity of the existing substations and electric circuits in the area. The project will increase reliability and power quality to the area and will support future load growth.
Construction is expected to begin in August 2022 and be fully complete by June 2023. Crews are expected to work Monday through Friday from approximately 7:00 a.m. – 5:00 p.m.

The proposed Brooklyn Avenue Substation will be located at 48 Brooklyn Avenue in Massapequa. The proposed substation will encompass approximately 0.76 acres and will be constructed on LIPA-owned property that is currently vacant.
Replacement and relocation of three existing steel transmission poles and associated pole-top equipment and wire, and installation of three new steel transmission poles and wires.
- Location of the site or right-of-way:
The transmission pole replacements will occur along an existing overhead transmission circuit, which is located just north of, and parallel to, the Long Island Rail Road (LIRR) tracks in Massapequa. Pole replacements will occur within this existing transmission circuit pole alignment. One new transmission pole will be installed within the pole alignment, and two other new transmission poles will be installed within the new Brooklyn Avenue Substation, which will be constructed just north of this transmission circuit.
- Description of the transmission facilities to be built:
Three existing steel transmission poles will be replaced with new steel transmission poles that will have a newer type of finish that blends in more naturally with the surrounding environment. These poles are currently approximately 63 to 65 feet in height, and the replacement poles will be approximately 75 feet in height. Of the three new transmission poles that will be installed, two will be approximately 65 feet in height and will be located within the new Brooklyn Avenue Substation, and one will be approximately 75 feet in height and will be installed within the existing transmission circuit pole alignment just north of, and parallel to the Long Island Rail Road (LIRR) tracks in Massapequa. The transmission pole to be installed within the existing transmission circuit pole alignment will have a natina finish, and the transmission poles within the new Brooklyn Avenue Substation will be gray or galvanized steel, to match the color of the surrounding substation equipment.
Five new underground 13kV distribution feeder lines will be installed, exiting the proposed Brooklyn Avenue Substation and continuing underground along Brooklyn Avenue, Veterans Boulevard, Hicksville Road (Route 107), New York Avenue, Central Avenue, Michigan Avenue and Broadway within Massapequa. Pole work will be completed in areas surrounding the proposed Brooklyn Avenue Substation, including within the Village of Massapequa Park, and the Hamlets of Massapequa, North Massapequa, Seaford, North Wantagh and Wantagh. This pole work will include the replacement of existing wood utility poles, as well as associated pole-top wire and equipment. Underground distribution cable will also be installed along Jerusalem Avenue and Express Way in Wantagh; Jerusalem Avenue and Hicksville Road (Route 107) in North Massapequa; and Merrick Road, Seaford Avenue and Locust Street in Massapequa.
Water Main Relocation
An approximately 140 linear foot section of water main supplying a fire hydrant located within the Town of Oyster Bay-owned property currently bisects the Proposed Substation property. In order to support the construction of the Proposed Substation, this water main will be capped within Brooklyn Avenue, immediately north of the Proposed Substation property. The fire hydrant will be supplied by an approximately 200 linear foot section of new water main constructed along Veterans Boulevard, connecting the fire hydrant to an existing water main located near the intersection of Veterans Boulevard and Hicksville Road (Route 107). After the new service is installed, the section of water main currently bisecting the Proposed Substation property will be removed.

Alternatives to the project were assessed, including:
Installing feeder lines from Bellmore, Plainedge, Massapequa and Sterling substations:
- Currently there is one spare feeder cubicle in each substation. This alternative would bring three new feeders in order to relieve the load on the existing, highly loaded feeders and support the area during normal and contingency events. This alternative would also reroute existing feeders in the Sterling area to solve load issues in the area.
Feeders from Berry Street Substation:
- This alternative would bring two new underground express feeders from the Berry Street Substation to the Massapequa Substation. One feeder would pick up load from the east side of the Massapequa Substation and the other feeder would pick up load from the west side of the substation.
- These two new feeders would help to mitigate the bank and feeder issues in the Massapequa Substation. Also, this alternative would provide extra support for the Plainedge and Sterling substations during bank contingency but would not reduce the existing load in these two substations. Both new feeders would run underground for 35,000 feet; one feeder would split to serve the east side of Massapequa Substation and the other to the west side. The west side feeder would run an extra 15,000 feet underground to reach the desired location. This project scope would also include the reconductoring of overhead main line for 4,500 feet and a 1,500-foot underground section to cross Seaford Highway. This alternative would also include six capacitor banks, 12 new ASUVs and 4 riser poles.
- This alternative would use methods of reducing electrical load in the area to defer the construction of a new substation. A 24-hour loading profile for each nearby substation was used to determinate the load reduction in each area. It was determined that the total amount load reduction needed to defer the project is very high.
Comparative merits and detriments of each location submitted:
- Install feeders from Bellmore, Plainedge, Massapequa and Sterling Substations: This alternative only targets the feeder normal and contingency overloads. It does not reduce the existing load in the banks. This alternative is a short-term solution and a new substation will be needed in the near future.
- Feeders from Berry Street Substation: This alternative is not cost effective and not recommended since future projects are expected to materialize at the Berry Substation.
- Utility 2.0/REV: This alternative is not cost effective.
Frequently Asked Questions
- Why is the proposed location best suited for the facility?
Nearby substations have no land available for expansion and their existing banks and feeders are running out of capacity to support the area during load growth, future load additions, and contingency events.
- Will there be tree trimming?
Yes, trees growing near power lines significantly increase the chance of power outages and pose safety risks. As we expand and improve our electric circuits, we will trim trees, where necessary, following our utility best practice model (ANSI A300 standards as well as the Best Management Practices Tree Pruning publication): 8 feet to each side; 12 feet above; and 10 feet below the distribution line and 18 feet to each side; 18 feet below the transmission line and no overhangs at any height.
- Will there be any power outages?
In the event that a brief outage is required, all affected customers will be notified in advance.
- Will there be any traffic interruptions?
There will be traffic disruptions along the project route as installation occurs. To ensure traffic moves safely, PSEG Long Island will provide cones, flaggers and signage at the work sites, as needed.
