FIRST, NEVER RUN A GENERATOR INSIDE OR WITHIN 25 FEET OF A HOUSE OR GARAGE. EXHAUST FUMES CAN KILL!
We lose power several times each year; rarely for more than a day or two. If it doesn't come back on within a couple of hours, I set up our 3500/4000W generator (around $500 these days). To give you an idea of what's involved . . .
The previous owners had a manual transfer switch installed on our main power panel that allows me to safely shift from street power to generator power. The switch attaches to a 220V receptacle in our garage. To use the generator, I first move the generator into the driveway and connect it to the 220V receptacle with its heavy 50' power cord. I then start the generator.
Next, I go to the main power panel and turn off ALL of the breakers. Then move the transfer switch from the street power to the generator power position. Finally, I decide which circuits I want to have powered and turn only that/those breakers back on. We only power circuits for a limited time and then only when needed so as to conserve gasoline. I have a chart that lists the power demands (normal and surge) for each of our major appliances and which circuits they're connected to.
Our generator does not provide sufficient power to run air conditioning or our range, so those two are "off the table". We choose a time to power our well. The well consumes almost all of the electricity the generator puts out, so when that circuit is powered on, its the only one. We use that time to get showers, flush toilets, wash dishes, &c.
We have oil/baseboard hot water heat which doesn't draw a lot of electricity, so we can run that as needed. Our chest freezer is good for a couple of days if we don't open the lid, but if needed our generator can handle it. The refrigerator has to be run more often, depending on how often we open it. Lights, television, computers, &c. don't use a lot of power so we can pretty much power those on at will.
You get the general idea. Obviously there's a lot of stopping and starting of the generator and changing of circuits. You can see why we wait to set up the generator until it is truly necessary. It's definitely an "event". If you decide to go this route, I strongly recommend having a manual transfer switch installed on your main electrical panel. Honestly, although it would be nice to have a whole house generator with an automatic transfer switch, for our purposes I just can't justify the $20,000 expense.
Hope that helps.
