If you live in Syosset, Muttontown, Upper Brookville or Old Brookville—or you're shopping there—you've heard of Propel NY Energy. In mid-September, New York's Public Service Commission took a major step on the project, while school districts that serve these towns kept pushing back. For homeowners and buyers, the useful question is not whether towers will rise (they won't—the lines are planned underground) but what happens next on our roads, and when.

Here's a clear briefing from public reporting—not speculation about sale prices.

What Propel NY Energy Is

Propel NY Energy is an approximately $3.26 billion underground and submarine transmission project by the New York Power Authority and New York Transco. Long Island Press reporting describes about 90 miles of new underground transmission through Long Island, Queens, the Bronx and Westchester, roughly nine miles of submarine cable under Long Island Sound, and connections to nine substations. The purpose is to increase transmission capacity and strengthen the grid.

On September 17, 2026, the Public Service Commission granted a Certificate of Environmental Compatibility and Public Need, as Long Island Press reported on September 21 (Larissa Fuentes). That certificate is a major milestone. It does not, by itself, authorize construction on every street. Work still depends on PSC approval of Environmental Management and Construction Plans (EM&CPs) and related notices to proceed.

Limited site work is expected later in 2026 pending additional approvals, with more extensive construction targeted for mid-2027 and completion aimed at 2030.

The Syosset-to-Shore Road Route Through Our Towns

For North Shore homeowners, the key stretch is the "Syosset to Shore Road Segment," mapped by Long Island Press on February 9, 2026 (Casey Fahrer).

It starts at the existing Syosset substation near Syosset High School, then runs west along South Woods Road, Syosset-Woodbury Road, Cold Spring Road and Muttontown Eastwoods Road, north on Route 106, west on Northern Boulevard, northwest on Cedar Swamp Road, then Glen Head Road, Railroad Avenue, Station Plaza and Kissam Lane to the Shore Road substation. Communities named on that path include Woodbury, Syosset, Muttontown, East Norwich, Upper Brookville, Old Brookville, Glen Head and Glenwood Landing.

A separate Ruland Road to Shore Road segment also passes Brookville, Upper Brookville and Old Brookville. Other Nassau lines touch communities farther west, including a Northern Boulevard corridor through Manhasset and a Glen Cove Road corridor through Old Westbury.

Lines are planned under existing public rights-of-way and utility properties. Propel said it adjusted routing near a residential neighborhood off Searington Drive in Syosset after local feedback. Construction pace has been described as about 50 to 150 feet of cable per day, moving segment to segment "like a train," so crews are not expected to stay on one block for years.

One honest caveat: detailed open-trench calendars for many North Shore streets belong to later EM&CP phases. Early filings cover items such as Shore Road clearing and drilling—not a full public schedule for every Syosset or Brookville street. If a listing sits on a named corridor, ask for the latest EM&CP status rather than assuming a trench date.

School Districts Keep Opposing

Syosset is a party to the fight. With North Shore and Roslyn, the Syosset school district filed a July 29 motion asking the PSC to dismiss or deny the application, LI Herald reported on August 7, 2026. The districts argued that information on construction impacts, electromagnetic fields and related issues was incomplete or deferred to future EM&CPs.

After the September certificate, opposition continued. At the North Shore Board of Education meeting on October 8, Superintendent Thomas Dolan reiterated "continued and active opposition," Long Island Press reported on October 12 (Larissa Fuentes). He read a joint statement from North Shore, Roslyn and Syosset saying the districts were "deeply disappointed" and "profoundly concerned" about the health, safety and well-being of students. Opposition dates to a December 2024 board vote; districts say legal remedies are still being pursued.

Glen Head resident Christine Panzeca urged a petition for rehearing before an October 17, 2026 deadline and asked for plain-language updates parents can follow. Separate North Shore disputes—including Sea Cliff's harbor concerns—remain in the news, and federal Army Corps permitting is still ahead. For Syosset and Brookville readers, the school-district record and the Syosset-to-Shore Road street list are the closer focus. Watchers often follow PSC Case 24-T-0446 for docket updates.

"Buyers in Syosset, Muttontown and the Brookvilles are asking us about Propel NY, and the best thing we can do is give them the facts: where the route runs, when construction is expected, and what's still being decided. If you own a home near the route or you're thinking about buying in the area, call Mike or me. We'll walk you through what's known today and what it means for your street."

Reliability Need and Local Concerns Both Belong Here

Project sponsors argue Long Island needs stronger transmission for reliability. Local school boards and many residents counter that student safety, construction disruption and incomplete street-level detail deserve more weight. Both sides are part of the public record.

Mike and Ron's role is not to litigate the PSC docket. It is to help buyers and sellers in Syosset, Muttontown, Upper Brookville, Old Brookville and nearby North Shore towns make calm decisions: which streets are named on preferred routes, which approvals are still outstanding, and how to read listings when a major infrastructure story is in the news. If you're comparing homes near South Woods Road, Cold Spring Road, Route 106, Northern Boulevard or Cedar Swamp Road, ask for recent comps and a plain read of what's public versus still pending. Panic helps no one; preparation does.
