4.2 Discussion
In developing the ratios of customers to employees, we reviewed the staffing level data
AmerenCIPS provided by job classification, in-house employees, and contractor employees at
year end for each year during the 1995-2006 time period and made several adjustments to
make the ratios consistent and easier to interpret.
4.2.1 Linemen Employee Ratios
The current Ameren Illinois organizational structure of six operating divisions includes
AmerenCIPS in divisions II, IV, V, and VI. AmerenCIPS’ field forces currently operate out of the
following 22 operating centers: Anna, Beardstown, Benton, Canton, Carbondale, Carthage,
Effingham, Gilman, Harrisburg, Jerseyville, Macomb, Marion, Mattoon, Olney, North Pana,
Paxton, Petersburg, Pittsfield, Quincy, Robinson, Tuscola, and Virden. During the 1995-2006
timeframe, AmerenCIPS’ divisions were re-aligned several times and included as many as 29
operating centers. The operating centers that have been closed or consolidated and the year in
which the closure or consolidation occurred are as follows: Herrin (2000), Lawrenceville (2003),
Taylorville (2000), Watseka (2003), and West Frankfort (1995). 4
AmerenCIPS’ in-house line crews are typically assigned work by operating center, which covers
a specific geographic area. Depending on the operating center work load, crews may also be
assigned work outside their operating center but within the division. Occasionally, but not often,
crews are headquartered outside their division during large construction projects. In-house
substation crews are assigned by division.
Outsourced line crews are typically assigned work based on geographic need or by specific
project. An outsourced crew typically works in one division on a project or multiple projects until
the projects are finished. They then may be assigned to another division or released. Forestry
or line clearance crews have been completely outsourced since 2004. They are typically
assigned by circuits that are due in the upcoming trim cycle. Outsourced substation crews are
assigned by project.5 This makes it difficult to report contractor staffing levels by operating
center.
Due to these inconsistencies in data and the consolidation of operating centers, calculating the
ratios by operating centers does not help draw any meaningful conclusions. As a result, the
linemen employee ratios were calculated based on the total AmerenCIPS customers and
linemen employees each year.
