Titan 138 - 13.2kV Substation - Public Utilities
Board, Brownsville, Texas
PUB needed a new dedicated industrial substation to
serve a new tire manufacturing plant in the city of
Brownsville, Texas. The station was built for maximum
reliability with dual 138 - 12.47kV LTC power
transformers. The 138kV bus has four tap positions,
two are for a future on-site generation plant. The
others feed two transformers which are configured with
automatic sectionalizing low-voltage breakers in
metal-clad switchgear. Basler parallel balancing
equipment and GE microprocessor relays assure continuity
of service, even if a transformer fails.
In Mr. Dunahoo's capacity of Project Engineer for this $1.5 million substation, he was responsible for all aspects of the design, scheduling, testing and final inspection of this project. The station was placed in service in the Spring of 1999.
Bellevue 115-25kV Substation - Georgia Power Company, Atlanta, GA
Georgia Power Company hired Power Consulting Engineers to produce
all the control wiring, protective relay system, and control circuit
drawings to modify this 33 year old station. Mr. Dunahoo was responsible
for utilizing Georgia Power Company's proprietary material ordering,
scheduling, and tracking systems as well as utilizing GPC standard
control practices. The engineering work was completed in December, 1999.
Swords Substation and Wolfskin Substation - Rayle EMC, Washington, GA
These 115-25kV stations are designed with fused 7.5 MVA transformers and
three 25kV feeder circuits. The cooperative hired Power Consulting
Engineers to procure the land, prepare and obtain RUS approval on
Environmental Reports, Design the stations and coordinate transmission
line work with the Transmission Supply Company. These projects were
designed, bid, scheduled, and tracked by PCE. Mr. Dunahoo was responsible
for preparing final drawings, writing the contract and specifications,
biding the projects, awarding the erection contract, performing the
final inspection, and placing the stations in service. The first
station was completed on time and under budget in June 2000. The
second is scheduled for completion in the Spring of 2001. PCE handled
the contract closeout process and complete all the RUS required forms
to assist Rayle EMC in obtaining RUS financing for these projects.
