Circuit Reliability Upgrades Begin in Commack, Elwood, Greenlawn, South Huntington and Dix Hills

(UNIONDALE, N.Y. – May 31, 2023) PSEG Long Island is improving the reliability of the energy grid in Commack, Elwood, Greenlawn, South Huntington and Dix Hills. The storm hardening work on this distribution circuit is part of many system improvements included in the “Power On” program.

“We are working hard to reduce the number of outages that occur during severe weather by strengthening the electric lines that directly power homes and businesses. This Power On infrastructure improvement project in Commack, Elwood, Greenlawn, South Huntington and Dix Hills is part of PSEG Long Island’s ongoing, multi-year effort to continue to improve electric reliability for customers.”

 - Peggy Keane, Vice President of Construction and Operations Services, PSEG Long Island

The work began in late May and will last for approximately six months. PSEG Long Island’s licensed and approved contractors will work along mainline distribution lines in Commack, Elwood, Greenlawn, South Huntington and Dix Hills. To ensure traffic moves safely, PSEG Long Island will provide cones, flaggers and signage at the worksites, as needed. Local officials will also be notified in advance regarding any potential traffic concerns.

The storm-hardening improvements include:

  • Stronger poles: PSEG Long Island will replace some existing utility poles with stronger, more durable poles that are capable of withstanding winds up to 135 mph. The new poles will be approximately the same height as the existing poles, have a stronger base and will be placed no more than 5 feet from the current pole locations. PSEG Long Island will actively coordinate the removal of old poles with other utilities and municipalities.
  • Narrow profiles: To help wires deflect falling limbs instead of catching them, PSEG Long Island will be installing shorter cross arms atop some poles.
  • Stronger wire: Current wire will be replaced with more resilient and durable wire.
  • Upgrading: PSEG Long Island will upgrade or replace worn equipment as necessary.

Crews will be working on the following streets in Commack, Elwood, Greenlawn, South Huntington and Dix Hills:

  • Colonial Street between Verleye Avenue and Beauty’s Hill Court
  • Elton Drive between Colonial Street and Elmont Lane
  • Eldorado Drive between Elmont Lane and Jericho Turnpike
  • Jericho Turnpike between Eldorado Drive and Dix Hills Road
  • Park Avenue between E Jericho Turnpike and Keeler Street
  • Broadway-Greenlawn between Little Plains Road and north of Dix Hills Road

PSEG Long Island prepares year-round for extreme weather to maintain reliable service for its 1.1 million customers. Since 2014, the company has made significant investments in strengthening the electric infrastructure. Using funding from both FEMA and LIPA, PSEG Long Island has completed storm hardening and reliability work on more than 1,000 miles of distribution mainline circuits.

Power On, a program that started in the spring of 2020, continues the work now that the FEMA program has concluded. Since the launch of Power On, more than 275 miles of the most vulnerable distribution mainline circuits on Long Island and in the Rockaways have been storm hardened with stronger poles, thicker wire and other modern equipment.

These investments have strengthened the system so that fewer customers experience outages and, when they do occur, the duration is shorter, especially during extreme weather. From the first quarter of 2022 through the first quarter of 2023, the sections of circuits that are storm hardened saw a 49% reduction in damage leading to outages compared to the rest of the distribution system.

Power On focuses on mainline circuits, the backbone of PSEG Long Island’s distribution system. The main lines feed the many branch lines that power the homes and businesses in individual communities.
