As Augie stated, Tn allows what is called a "service release". This allows the POCO to energize a service. It is intended so that the house/building can have power for final inspection. Power has to be there in some form for the final inspection. Some inspectors were having problems with using power from a temp pole to power a panel. That's because the GFCI on the temp pole would trip because of it being bonded both at the temp pole and the service panel. The same thing that happens on a generator with GFCI and the neutral & gnd are bonded and then connect to a service where it is also bonded.
Most, including myself, use the Service Release so that HVAC equipment can be used to acclimate flooring before it is put down or for proper drying of Drywall mud, also for painters. This hopefully can be completed within 45 days as that is the limit for a Service Release. If it expires, you have to get another permit/inspection.
To get an inspection for a Service release, all is needed is the SE conductors landed, the GES in place, and (1) GFCI circuit & outlet wired. I usually go ahead and make up all gnds & neutrals (excluding neutrals for GFCI/AFCI) in the panel. This is just to make it easier when I make up the branch circuits for the final.
Although some inspectors made it sound like you were required to get a Service Release, it is not mandatory if you can get power to the service by other means. I just finished a barn/garage and I used the power from the temp pole to get a final. I put in two regular 20A breakers in the temp panel and ran a 3-wire cable to the service panel. This bypassed the GFCI on the temp panel but because the receptacles in the garage were GFCI I felt it was safe and it was only for final inspection.
I have used a generator for final but discovered that I can use my inverter in my van to power a panel by jumping the two legs. The GFCI receptacles can be checked this way and also lighting. Obviously no 2-pole loads but the inspector was fine with not checking them as he saw they were wired correctly.
Some POCOs require an inspection on an existing service if the power has been shut off for an extended period of time (varies from POCO to POCO). Some areas require the Service release to check the existing GFCI/AFCI.
