UTEC provided design, engineering, and construction observation for a 230 kV switchyard and associated transmission lines for a 180 MW gas fired turbine generator. The project included a 230/13.8 kV, 217 MVA unit connected step-up transformer, generator iso-phase bus, a 25 MVA 230/4.16 kV auxiliary transformer, three 230 kV OCBs, rigid bus low profile substation design, two 230 kV transmission lines and associated protection and control equipment.

The project also included revenue metering, telemetry, and alarming using a PLC system accessed over an intranet using TCP/IP.

The project was completed and ready for synchronization seven months after award of the engineering contract.
