I
n 2013 Anadarko Petroleum and
Samuel Engineering outlined
a two-phase, expansion project
for its Ft. Lupton Station. The
Lancaster Plant, located in Ft.
Lupton, CO has an architectural
layout that includes a cryo-station, a
180’ demethanizer tower, a 90’ flare
stack, three compressor refrigeration
stations, two 12,900 horsepower
residue compressors, and two amine
gas treatment buildings.
Kenny Electric was initially
engaged with the project in
June 2013, when contracted to
complete a series of electrical and
instrumentation installations at the

Ft. Lupton Station including Lancaster Plant
Lancaster Plant. This aspect of the project completed
in May, 2014 and took over 90,000 Kenny Electric
man-hours to finish.
In November, 2013, prior to finishing the initial
work, Kenny was asked to participate in a new aspect
of the project that included expansion of the Lancaster
Plant to support the station’s natural gas production
goal of 500 million cubic feet of raw gas per day.
This work involved installation of five electric motors
(4,160 volt/3,775 horsepower) to feed Lancaster’s
power needs, and also included adding new 13,200
volt-service, feed-thru, cable trays which ran from
Lancaster PDC to Ft. Lupton Station, a distance
of over 1,600 feet. Installation of a motor control
center (MMC), a programmable logic controller
(PLC), communication cabling, and automation and
pneumatic tubing were also involved. This work
completed in March of 2014 and added an additional
35,000 man-hours to the expansion project.
The gas compression expansion project
required Kenny to engage separate crews to work
simultaneously at Anadarko compressor sites in
Brighton, Hudson, Vollmer, St. Vrain, Meade and
Tri-town Stations. It was critical to the success of the
project to bring these compressor sites online as quickly
as possible. Each station was installed with six gas
compressor motors (1,775 horsepower) and included
new 1200 amp electrical service, a motor control center
(MMC), cable trays, a PLC unit, communication

cabling and automation and
pneumatic tubing. This aspect of the
project required 110,000 man-hours to
complete.
One of the largest challenges of
the Anadarko expansion project was
balancing labor costs and man-hours
against the broad scope of work and
compressed timeline. Safety was
another area of concern. Extremes in
hot and cold temperatures threatened
workers with exposure, and working
in an environment filled with live gas
meant taking extra precaution. While
often the schematic drawings were
only 60% complete prior to the start

of the build-out, the project remained
successfully on target because Kenny
was able to assist with engineering
design and manage to the needs of
plant by minimizing shutdowns.
Phase-two of the Anadarko
expansion mirrors Phase-one in every
aspect and is scheduled to complete at
the end of April, 2015. It is estimated
this phase of the project will require
over 100,000 Kenny-Electric manhours to complete.

Denver, Colorado since 1974. It has
a dedicated workforce of over 250+
highly-skilled individuals who serve
industrial and commercial clients
