Compare output of UNIX command and match data to text file

I am working on an outage script and I run a command from the command line which tells me the amount of generator failures in my market. The output of this command only gives me three digits to identify the site by. I have a master list of all sites in a separate file, call it list.txt. If my command appends to file outagereport.txt, I want to use SED or something else to look at the output of that file and match it to the sites in the list.txt file and then modify the original file.

So, lets say that I run the following command:

Code:
  TICLI "op:alarm,all" | {  printf "Austin Generators Running Alarms:\n" && grep GEN | grep RUN || printf "Austin Generator Alarms: Zero \n"; }>> AustinOutageReport.txt

and I get the following output:
Code:
Austin Generators Running Alarms:
     CELL 40 GENERATOR RUNNING

and my list.txt file has the following entry in it:
Sitename-market-0040-awesomesite

How can I get UNIX to look at list.txt and replace the text of cell for generator running with the text of list.txt that says Sitename-market-0040-awesomesite?

My thought was to use a sed substitute command for this but if I do that I will have a script with over 1800 sed substitutes.

shtool subst [-v|--verbose] [-t|--trace] [-n|--nop] [-w|--warning] [-q|--quiet] [-s|--stealth] [-i|--interactive] [-b|--backup ext] [-e|--exec cmd] [-f|--file cmd-file] [file] [file ...] DESCRIPTION
This command applies one or more sed(1) substitution operations to stdin or any number of files. OPTIONS
The following command line options are available. -v, --verbose Display some processing information. -t, --trace Enable the output of the essential shell commands which are executed. -n, --nop No operation mode. Actual execution of the essential shell commands which would be executed is suppressed. -w, --warning Show warning on substitution operation resulting in no content change on every file. The default is to show a warning on substitution operations resulted in no content change on all files. -q, --quiet Suppress warning on substitution operation resulting in no content change. -s, --stealth Stealth operation. Preserve timestamp on file. -i, --interactive Enter interactive mode where the user has to approve each operation. -b, --backup ext Preserve backup of original file using file name extension ext. Default is to overwrite the original file. -e, --exec cmd Specify sed(1) command directly. -f, --file cmd-file Read sed(1) command from file. EXAMPLE
# shell script shtool subst -i -e 's;(c) ([0-9]*)-2000;(c) 1-2001;' *.[ch] # RPM spec-file %install shtool subst -v -n -e 's;^(prefix=).*;1 $RPM_BUILD_ROOT%{_prefix};g' -e 's;^(sysconfdir=).*;1 $RPM_BUILD_ROOT%{_prefix}/etc;g' `find . -name Makefile -print` make install HISTORY
The GNU shtool subst command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 2001 for GNU shtool. It was prompted by the need to have a uniform and convenient patching frontend to sed(1) operations in the OpenPKG package specifications. SEE ALSO
