The 230 kV system will also power a 55/27 kV traction power substation through five 230/55 kV transformers, providing adequate power for a 14.5-mile segment of the NJT Morris and Essex Lines. The design and creation of a temporary substation enabled the demolition of the existing facility and construction of the replacement without disrupting service. Such resiliency is crucial for a facility located within 10 miles of the Atlantic coast. Besides requiring less space than air insulated substations, gas insulated facilities are less sensitive to the harmful effects of pollution, as well as salt, sand, and precipitation. Substation design consists of a new 230 kV, four-bay, 12-breaker, gas insulated substation (GIS) enclosed in a new building. The project involves replacing the existing Mason Substation with new state-of-the-art equipment and protection schemes.

As a flow-through facility for power transmitted by PSE&G throughout northern New Jersey, the substation is also critical to the reliability of electric service across the region.

The substation also provides 13 kV power to the maintenance yard, as well as to the NJ Transit Rail Operations Center, the command and control center for all train movements statewide. Gannett Fleming is providing design, engineering, and procurement services for the replacement of the Mason Substation, a facility considered the most important traction power substation facility in the NJ Transit system. As well, key facilities damaged by Hurricane Sandy needed reconstruction to maintain service and improve system resiliency.

As the rail fleet grows, the power infrastructure serving the MMC needed to be upgraded to keep pace with growing energy demand.

The safety and reliability of the NJ Transit rail fleet is maintained at the Meadows Maintenance Complex (MMC), one of the most energy-intensive of the agency’s facilities. The third largest bus, rail, and light-rail transit system in the U.S., NJ Transit provides 270 million passenger rides each year across a service area that covers 5,325 square miles.
