Construction starts this month on 2.5 miles of underground cable in Central Islip to power booming growth. Work begins at Tech Park substation on DPW Drive.
As Central Islip sees surging residential and commercial builds amid Long Island's housing boom, PSEG Long Island's **Tech Park Feeder Project** breaks ground this month. Crews will install **2.5 miles of 750 CU underground cable** starting at the Tech Park substation on **DPW Drive** to handle rising electric demand.
Work launches along **DPW Drive** through the **Islip DPW yard** and under **Carleton Avenue**, then south of **Court House Drive** to **Smith Street**. It continues on **Court House Drive** between **Carleton Avenue** and **Eastview Drive**, and **Eastview Drive** to **Admission Drive South**. Methods include horizontal directional drilling or open trenching, with temporary drill pits and a pole replacement at southeast **Carleton Avenue** and **Clift Street**.
Crews work Monday-Friday, 7 a.m. to 5 p.m., with some shorter days to 3 p.m. and occasional weekends. No planned power outages are expected, but advance notice will come if needed. Traffic and parking disruptions are likely, with cones, flaggers, and signage for safety. For updates on road impacts, PSEG Long Island publishes construction notices on its official site.
This **Tech Park New Feeder 7S-8H3 Project** (Bid #225421) addresses load growth from new homes and businesses in **Central Islip, Suffolk County**. It includes 6 PMH switchgears and 3 switches over **13,200 feet** of cable, tying into existing gear. Completion is set for December 2025, ensuring reliable power for spots like nearby **Islip Town offices** and growing commercial hubs. The project is part of a broader push across the region — similar to how the Town of Islip broke ground on the $65M One Carleton Green redevelopment in Central Islip, signaling strong momentum for the area. Demand for infrastructure upgrades is also being driven by major new tenants, such as Redefine Meals moving into the former Entenmann's factory in nearby Bay Shore, adding significant new load to the local grid. Suffolk County continues to coordinate with utilities and municipalities on long-range planning to support this growth.
