Madison Substation Upgrade Project

Project Overview

The PSE&G Madison Street Substation Project is a multi-million dollar capital improvement that will upgrade the electric distribution system to make it more reliable and resilient in the wake of severe weather. This work includes constructing a new, elevated substation featuring state-of-the-art, 69,000-volt (69kV) gas insulated switchgear to serve and benefit Hoboken businesses and residents.

Working closely with the City of Hoboken, PSE&G enlisted the services of a Hoboken-based architectural firm to design the Madison Street facility to assimilate within the urban fabric of the city.

In addition, PSE&G will raise critical electric transmission facilities and distribution equipment above new Federal Emergency Management Agency (FEMA) flood guidelines, replace aging infrastructure, and install new technology that can monitor the station remotely and restore power more quickly if an outage occurs. These improvements will enhance the safety and reliability of our power delivery system and achieve resiliency during severe weather.

New 69kV circuits will connect the new Madison Street station to existing stations in Jersey City, Kearny and North Bergen and strengthen the local grid/circuits that support electric reliability in Hoboken. These lines will utilize an existing right-of-way. The old poles will be removed after the new poles are installed and the overhead infrastructure is transferred from the old poles to the new poles. Segments of the circuit will be underground.

More specifically:

  •  The circuit route from Jersey City will travel west on First St. between Paterson Ave. & Jackson St. / north on Jackson St. to Seventh St. / one block east on Seventh St. / and north on Monroe St. to the Madison Substation.
  • The line coming from Kearny will enter Hoboken at Newark St. & Madison St., before traveling north on Madison St. directly to the new substation.
  • The North Bergen line will enter Hoboken on Fifteenth St. heading east for a block and  a half, before turning south on Jefferson St. From there, the route continues two blocks down Jefferson St. until Thirteenth St., where it heads west for a block to Madison St.…and on to the Substation.

The substation upgrade portion of this project received approval by the Hoboken City Council and Planning Board on August 9, 2017. Construction of the new substation began in May 2018. Beginning in July 2018, and continuing through October, new underground cables will be installed along the following streets:

  • Monroe St. between Second St. & Twelfth St.
  • Jefferson St. between Fourth St. & Twelfth St.
  • Bloomfield St. between Second St. & Fourth St.
  • Fifth St. between Jefferson St. & Grand St.

Safety is our primary goal. PSE&G is partnering with the Hoboken Police Department to minimize traffic concerns or inconveniences to the public during construction.

    What is 69kV Transmission?

    69kV transmission lines are the standard of the 21st century, linking higher voltage lines with switching stations and substations. They will ultimately replace and enhance a 50+ year-old system built on 26kV lines, increasing reliability, capacity, and safety.

    What will these projects do?

    PSE&G is currently improving its electric reliability statewide in-order to upgrade its utility infrastructure. PSE&G infrastructure upgrades include the addition of a 69kV network that will alleviate the demand on the existing 26kV network. These upgrades will increase both electric service reliability and system redundancy to ensure safe and reliable electric service to our customers.

    Why are these upgrades needed?

    These upgrades are needed to address the increased demand for reliable electricity throughout PSE&G service territory. As population has increased and consumer electronic needs have evolved, the 26kV legacy networks of the last century have been taxed. The addition of a 69kV network will alleviate the demands on the existing 26kV network.

    What type of construction will these projects entail?

    These projects will install 69kV circuits connecting stations to each other. Underground and Overhead pole line construction is taking place throughout the state. New 69kV circuits are being installed to connect each upgraded station and existing utility poles will be replaced with taller sturdier poles that combine existing 26kV, 13kV, or 4kV circuits. New 69kV Gas Insulator Switchgear (GIS) will also be installed at various stations in multiple municipalities.

    How tall will the replacement poles be?

    The replacement poles will range in height between 57 and 65 feet.

    What is the difference between the existing and new line voltage?

    Existing pole lines throughout the state carry 4kV, 13kV and/or 26kV lines. The new pole lines will carry these existing lines in addition to a new 69kV line for added reliability and capacity.

    How long will construction last?

    As of December 17, 2014 PSE&G has augmented or replaced approximately 209 miles of its 26kV network with 69kV lines in several New Jersey municipalities, all in an effort to ensure that the people of New Jersey have the power they need when they need it. Continued substation and pole line construction is currently scheduled through 2021.

    How will this impact traffic?

    Traffic may be slightly impacted during construction; however PSE&G will work with municipal safety and traffic departments to minimize any traffic issues that arise during construction.

    Safety of the public and construction crews is our highest priority. During construction, it is essential that you and anyone occupying your property, including children and pets, refrain from going near our construction work zones.

    What are the benefits to the region?

    This project will provide safe, highly reliable service.  It will also create construction jobs, and provide municipal revenue though requisite permits. The enhanced electrical infrastructure will help support regional economic growth.

    What approvals are you seeking?

    PSE&G will secure necessary permits and approvals from local governing authorities wherever construction is taking place, as well as the New Jersey Department of Environmental Protection and other applicable state agencies.

    Do the lines produce electric and magnetic fields?

    Electric and magnetic fields are present wherever there is a flow of electric current, whether in wires in the home, electrical appliances, or power lines. Electric fields are produced by the voltage or electrical pressure in a wire and are present even if an appliance is turned off, as long as it is connected to a source of electric power. Magnetic fields are produced whenever there is a flow of electric current through a wire. Electric and magnetic fields are not visible, like other fields such as a gravitational field or a temperature field.

    Are electric and magnetic fields (EMFs) harmful?

    The overwhelming body of scientific study shows no definitive link between EMF and human health issues. Since 1977, concerns over magnetic fields and possible health effects have been the subject of numerous scientific and regulatory review panels, and extensive research and studies continue to be funded in this field of study.

    After nearly 30 years of worldwide research, there are no direct or causal links between electric and magnetic fields and adverse health effects. New Jersey has standards regarding maximum permissible electric fields at the edge of transmission line rights of way. However, there are no state standards with regards to magnetic field levels nor are there any federal rules, regulations or standards for either electric or magnetic field levels.

    Magnetic fields from appliances like hair dryers, microwave ovens, and motorized appliances are often stronger than the fields directly beneath power lines. PSE&G will design and install this line according to appropriate state and federal guidelines related to safety and environmental impact.

    Tree Maintenance Update - Jackson Street

    After inspecting the circuit route on Jackson Street, PSE&G—along with Quanika Stover, Hoboken’s Urban Forestry Coordinator—identified potentially hazardous trees that could be saved but are in need of pruning. There are also trees that will need to be removed and replaced because the health of the tree is in decline and the trimming would be too severe.

    We do not take tree removal lightly, as we know how important trees are to residents, the environment and community aesthetics. Rest assured we only remove a tree if it presents a true hazard to public safety. PSE&G’s 69kV Urban Reforestry initiative includes replacing trees that have been removed in order to accommodate the construction of a new circuit. We will plant utility-friendly, replacement trees in the spring. These new trees will not grow into electric conductors, providing an environmental and safety asset for current and future property owners.

    In addition, PSE&G will conduct directional pruning on the remaining trees that are consistent with the standards of the International Society of Arboriculture to help ensure the health of the trees.

    Tree Maintenance

    According to City Code (Chapter 136), it is the responsibility of the adjacent property owner to care for sidewalks and street trees. In order to keep the new tree healthy and beautiful, please:

    1. Water the tree every other day with five (5) gallons, totaling at least twenty (20) gallons per week. The most important factor in the survival of Hoboken's street trees is that they receive the proper amount of water. A Treegator bag will be provided with your new tree. A “treegator” bag is a watering bag that fills up quickly and drains slowly, this allows water to soak down to the roots where it is needed.

    2. Consider installing a tree guard. Tree guards shall have three (3) sides, the open side facing the curb, 12-18 inches high, around the entire perimeter of the tree hole with bark mulch pursuant to Hoboken Shade Tree Commission’s standards available at www.hobokennj.gov/trees.

    If you have any questions about trees, please contact Urban Forestry Coordinator Quanika Stover, qstover@hobokennj.gov or 201-420-2000 ext. 4004. If you’d like more information about PSE&G’s electric system upgrade, please call Reliability Hotline at (800) 901-5035.


    PSE&G will take all necessary steps to avoid any major inconvenience to our customers in the area. However, road and lane closures with possible detours will be necessary during construction. Road closures will not take place prior to 9:00 AM If possible, motorists are encouraged to travel an alternate route until the work is completed. Hoboken Police will be on site during construction hours to oversee and assist with new traffic patterns. All efforts will be made to keep interruptions to a minimum.
