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.

SYSTEMD-GETTY-GENERATOR(8)				      systemd-getty-generator					SYSTEMD-GETTY-GENERATOR(8)

NAME
systemd-getty-generator - Generator for enabling getty instances on the console SYNOPSIS
/lib/systemd/system-generators/systemd-getty-generator DESCRIPTION
systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console(s), if they can function as ttys and are not provided by the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer consoles, if execution in a virtualized environment is detected. If execution in a container environment is detected, it will instead enable console-getty.service for /dev/console, and container-getty@.service instances for additional container pseudo TTYs as requested by the container manager (see Container Interface[1]). This should ensure that the user is shown a login prompt at the right place, regardless of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line argument such as console= to get both kernel messages and a getty prompt on a serial TTY. See kernel-parameters.txt[2] for more information on the console= kernel parameter. systemd-getty-generator implements systemd.generator(7). Further information about configuration of gettys can be found in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and Elsewhere)[3]. SEE ALSO
