The Susquehanna-Roseland Electric Reliability Project is a 500,000 volt 145-mile transmission line passing through 16 municipalities from the PP&L Susquehanna Nuclear Plant in Pennsylvania to PSE&G's substation in Roseland, New Jersey. PSE&G is building the New Jersey portion of the line, while PPL Electric Utilities, based in Allentown will build the Pennsylvania portion. The power line project was mandated by PJM Interconnection, the regional entity responsible for planning the transmission system, who determined that the new line was necessary to ensure reliable electric service. PSE&G constructed the line which was in service by the 2015 summer demand.

The New Jersey portion of the line is 45 miles, beginning in Harwick, Warren County, proceeding east to Andover, Sussex County, and on to Jefferson, Morris County. The route continues east o Montville and then turns south to Roseland, Essex County. Each switching station along the line will be upgraded to more efficient Gas Insulated Switchgear (GIS) to reduce the area needed for the switching equipment. Each line will replace existing air insulated connections to transformers and bus work with Gas Insulated Bus (GIB) or solid dielectric cables. The majority of the newly installed Gas Insulated Switchgear (GIS) is housed in new 50' high precast concrete GIS buildings with integral 20' hihg control rooms. Hoch serves the project team as the architect and engineer for the GIS buildings and control rooms for each site.

Hoch has completed the following projects for PSE&G:

Branchburg - 21,600 s.f.

Bayonne - 10,800 s.f.

Hopatcong - 15,750 s.f.

Roseland 230 - 14,600 s.f.

Roseland 500 - 15,050
