I live in Nashville, Tennessee and am wanting to build a room addition onto my home. But the wattage that is currently in the home will not suffice. I will need more wattage. How much does it cost to get additional wattage in my home.
No one on this group knows how much "wattage" your house currently ( pun intended ) has.
No one on this goup knows how big your proposed addition is going to be.
No one on this group can answer your questions as you asked.
Call 5 different electricians in your area, get 5 bids. In getting bids, give them a detailed written list of what ou have and what you want, so that they are all bidding on the same job.
Let them all know that there ill be multiple bidders, and that they are in competition.
It seems pretty clear from your initial post that for you, this is not a DIY project.
Put in writing for the electrician how much wattage you need might not get you the best price.
If you have space in your panel for another single pole breaker and you are not going to run a window AC unit, you should have enough wattage for the extra room. You probably have enough room even if you are going to add an AC unit.
BTW the correct value you are considering is the amperage not wattage.
Lets get real ONLY upgrade to 200 amp service which will likely require a new main breaker cabinet, new service drop and new meter can along with new main grounding
Haller, let me clear something up for you. a "service drop" is usually referring to the overhead line from the pole to the house, owned by the utility company, which they upgrade if and when they deem necessary. The service entrance conductors are the ones on the house owned by the customer

65 cents per watt. with a minimum of $1000, and a $10,000 surcharge for heavy lifting if I have to put more than 10,000 watts on my truck. Local fees may apply. Wattboxes and wattwatchers will be the responsibility of the consumer if local codes require their use.

What you may need is a larger main or (slightly less favorable) a subpanel. A panel is about $100, wiring $100, labor $500. Get 3-5 estimates with references and written proof of insurance/bonded, years of experience. You'll find that pricing can greatly vary and many workers can't produce written proof of insurance. Don't risk an electrical fire.
I had my service upgraded to 100A, had an outside light put in (I supplied the fixture) , had two receptacles added, had a light switch made into a 3 way and labor and material was only $200. This was all done by a licensed electrician.
