Nashville Electric Service is working hard to keep its
customers from singing the blues about power
losses. The electric company is using geographic
information system (GIS) software to assist in the
planning, design, operation, and maintenance of its
complex electric network. GIS has been instrumental
in improving NES' operations management and
decreasing storm outage recovery time.
The company's 87,538 distribution transformers, 253
distribution substations, 5,619 miles of power lines,
and approximately 200,000 utility poles can all be
viewed via the NES intranet, complete with company-
wide access to GIS data and up-to-date information
on its electrical system and basemap data.
NES uses an automated vehicle location (AVL)
system, which helps dispatch and service crews
better serve the company's 351,000 customers within
NES' 700 square mile service territory. AVL gives
dispatchers the ability to view work crew locations in
real time. Since NES began using AVL, its hazardous
energy control procedures are less complicated and
more rapid, thus increasing safety and reliability.
NES also provides their customers with a real-time
map via their website, highlighting regions that have
reported an outage, the time the outage was reported,
number of customers affected and a street map of the
affected areas. (Power Map Web page,
www.nespower.com.)
GIS provides many more benefits to NES, including,
but not limited to, NES' vegetation management
system, outage management planning, disaster
preparedness planning, and land use
planning.

Today's Electricity Safety LESSON:
7200 Volts vs Log Truck 7200 Volts wins. (Jackson, TN) This happened Wednesday, July 23rd, out by the
airport in Jackson, TN. The driver was attempting to
throw the logging cable over the logs to secure them &
as you can see, hooked the electric line instead!
He said the tires began to fry within seconds.....very lucky man...he could easily have been fried himself! |
