The scope also included the installation of an isolation wall between the 230-13 kV transformer being replaced, an existing transformer, and 13 kV bus. This presented a unique engineering challenge because the transformers were located closely to one another and there were existing support structures within the desired isolation wall footprint that limited the design. Additionally, the design had to consider the construction feasibility and overhead clearances because a set of energized overhead transmission lines ran directly above which would restrict how high construction equipment could be raised during installation.

TRC provided engineering, procurement, construction, and management services under the terms of an Engineer Procure Construct (EPC) contract.

During construction the project encountered a setback when the transformer and associated parts were damaged by a storm in transit. TRC Project Managers and Construction Managers developed an alternative solution that allowed for the transformer to be installed without missing the scheduled outage. They coordinated these efforts with PSEG, the transformer supplier, construction contractors, and TRC project team in order to successfully install a transformer and place the station back into service as scheduled.
