Kupper Engineering, Inc. (KEI) provided electrical engineering services for a 3.4 MW biogas food waste recycling plant, which diverts 100,000 tons of organic material from landfills to produce approximately 29,000 megawatt-hours of steady state power on an annual basis. Services included 13.2kV medium voltage interconnection design and PSE&G documentation, as well as electrical engineering of the medium voltage system for grounding design, 15kV medium voltage cables, conduits for SCADA connections to the biogas SCADA system, and design of generator step-up (GSU) transformers. KEI provided a short circuit and coordination study for the 15kV systems and generators, as well as relay settings per PSE&G requirements. Our team also provided site support during initial energization by loading the relay settings file, assisting the NETA testing company with the witness test, and finalizing the relay program at switchgear startup. Structural engineering design services were provided by a subcontractor to KEI, and included structural pad design for the switchgear pads and GSU transformers.
