The Antelope Station Grid Switching Expansion Project will allow an existing generating station to switch between the SPP and ERCOT grid systems. Kiewit Engineering and Design is designing the switch to a grid configuration consisting of a single-breaker, double-bus.
The Kiewit and Henkels & McCoy team (Kh&m) was selected to construct the New Jersey portion of the new Susquehanna to Roseland Electric Reliability Transmission Project.
Kiewit was selected by Public Service Electric & Gas (PSEG) for engineering and procurement services on the Northeast Grid Reliability Project. The project included upgrading existing tranmission lines, converting substation configurations and adding underground circuit to increase capacity while reducing transmission system congestion.
PSE&G selected KHMA, a joint venture comprised of Kiewit Power Constructors, Henkels & McCoy, and Aldridge Electric, to construct the Bergen-Linden Corridor Overhead project. Designed to replace the existing double circuit 138kV transmission system from Bergen to Linden with a double circuit 345kV transmission system, the project will eliminate electric system capacity issues in northern New Jersey and provide better power quality in the region. PJM Interconnection determined the new transmission system was necessary to ensure reliable electric service, eliminate anticipated transmission constraints, and respond to PJM/Federal Energy Regulatory Commission (FERC) mandated infrastructure expansion. The KHMA team is responsible for removing the existing transmission lines and lattice structures, clearing, temporary access roads and bridges, erosion and sedimentation controls, foundation installation (drilled piers and vibratory caissons), steel pole erection, hardware and insulator installation, conductor, shield wire stringing, and fiber optic splicing.
The project included the design and construction of transmission structure foundations, including upgrading and converting existing 138kV to 230kV with new structures, power conductors and OPGW. The project also incorporated the demolition and reinforcement of existing 138kV structures.
