Lemon Gulch Substation
and Transmission Line
Stanley Consultants, Inc.
Stanley Consultants provides engineering services for Intermountain Rural Electric Association
(IREA) in Colorado. IREA provides electrical
service to a 5,000-square-mile territory.
Douglas County, as well as future development in southwest Parker, which is a high-growth suburb of Denver, Colorado.
Lemon Gulch substation has been designed
with standard-rig bus profile equipment with
an eight-foot galvanized chain link fence sur-
rounding it. Substation lights will be installed
for emergency use only and distribution feed-
ers will exit the substation underground. The
substation is unmanned and, once construc-
tion is complete, traffic will generally consist
of substation technicians visiting the site
once or twice a month for maintenance pur-
poses, unless there is an emergency. ;
In addition to engineering issues, IREA faces
sensitive environmental issues such as endangered species, natural flora and fauna, esthetics in high-growth areas, noise proximity, and
services accessibility. Bentley 3D software has
become a very useful tool for design purposes,
client reviews, and public presentations.
IREA is in the process of constructing a new
230-12.47 kV electrical distribution substation, which it will call the Lemon Gulch substation. Lemon Gulch will serve anticipated
loads from the well-head pumps to be
installed at the Reuter-Hess Reservoir in

gas will be exhausted
into two new chimneys
that will consist of a concrete shell with fiberglass liners for each.
Shaw Stone & Webster, Inc. was charged with
the design of a flue gas desulphurization
(FGD) system with power generating units at
1,200 megawatts each. The units will be located within Stokes County, North Carolina, and
are fueled by eastern coal. The addition of FGD
systems is mandated by the North Carolina
Clean Air Pollution Control Authority.
The FGD system technology to be utilized is
wet FGD limestone — forced oxidation with
a wallboard-grade gypsum produced as a
byproduct. The components of such systems
include alloy steel absorber towers and car-
bon steel inlet/outlet ductwork for each unit.
Common limestone receiving, processing,
and handling facilities, as well as common
gypsum dewatering and storage facilities, will
support the process. The desulphurized flue

will be added. To sup-
port additional electrical
loads, new station service
transformers will be
installed in parallel with
the existing station service
transformers.

texture mapping and lighting based on plant
location, climate, and lighting sources. ;
