Rebuild Electrical Distribution System
Rebuild existing 12kV Substation
MCAS- Cherry Point, NC
Expand two – 12 kV Switchgear stations.
Replace all breaker electromechanical relays with
Install SCADA System
Design communications system
The MCAS – Cherry Point has a 12 kV Distribution System with
two Points of Delivery from Progress Energy. The system is
made up of two 12 kV overhead substations at the Points of Delivery and eight 12 kV sectionalizing stations consisting of
outdoor switchgear cabinets.
UTEC completed design drawings and specifications using the
military specification program SpecsIntact for the following
scope of work:
Demolition of the obsolete wood pole structure Substation
rebuilding the station with steel structures and new feeder
Change out obsolete electromechanical relays in Substations
1 and 2; and Sectionalizing
Stations A, B, C, D, E, F, G, and H
with approximately eighty SEL-microprocessor
Replacement of obsolete air break circuit breakers in
Sectionalizing Station E with vacuum
Addition of two breakers in Sectionalizing Station H.
Design, installation, and programming of a SCADA system.

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.
Other Projects Includes:
