My parents looked at the gauge this time and figured about 2% of the submarine for 24 hours of generator.

I currently have a manual transfer switch installed, and connect a portable Generac in case of emergency.
Can the MTS be changed to an automatic easily?

How many kwh required to recharge a troll?

Do you have LCM's installed?

Load control modules? Nope…one transfer switch to cover the whole house …power was out for 24 hours during the windstorm a few days ago and all things were running fine . 22kw is more than enough. you know when they install the generator you tell them everything you have and they do a calculation. Obviously if 22 kW wasn’t enough I would be tripping the circuit breaker all the time or it would be shutting down due to overload. It doesn’t. Toronto Generators installed it and they know what they are doing. This is the third generator they’ve installed for me over the years at two different properties

Probably because it's a small incremental amount in the over all cost. When I looked, the smallest unit (8kW) was about $3500, and I could get an 18kW for about $5000. It's the installation that's expensive.

What's the point if you have to start up the generator anyway?
Don't really need a calculator. Just a quick read of your needs and it's obvious you need a bigger genny.
Frankly I'd say you really need an even bigger generator but once you pass 22kW the price jumps significantly.
Interestingly, the 22s are being phased out to be replaced by 24s.

It’s worked fine for years through a few outages so I’m good. I would have gone bigger but this is what they suggested…never had a problem with flickering lights or overload warnings . Don’t see why I need bigger
Not a baller if you can't get along with a bunch like minded people. Just an anonymous someone with a big ego.F'n ballers in here.

Reality check, a 100 amp service is 24,000 KVA IF the full 100 amps are being drawn (full 100, not slash). For KW, well we need to know the power factor (ELI the ICE man.... for the EEs in the crowd) but for most large home loads I expect it to be close to 1 and therefore close to KVA.
BUT.... what about a 200 amp service.... first, are you ever going to draw 200 amps, very unlikely.... Next, are you going balls to the walls running everything full blast during a power outage or can you be an adult and maybe wait a couple of days.... to run the welder, to do laundry, maybe turn the AC up a couple of degrees or off, wait to run the stove full blast, wait out the EV charge or do it overnight.... Resistive electric heat is a bit of a wrinkle in an ice storm. Next is this an emergency only thing with multiple days on a regular basis or is it a few hours here or there with very rare multi-day???
Of course the guys selling generators say you need to go big.... Just like car dealerships with rust proofing, all the up sells, etc.. Some of the numbers quoted here are silly from an EE perspective. There will be a sweet spot in regards to size vs install costs but a sober second thought may be a good idea. You also need to determine if your NG service can handle the extra load to power the genny plus all the gas appliances.... If the genny guy can't figure out electrical load, how can they figure out the NG!

The upside if you have a pool heater, as long as you dont run it and the generator concurrently, you should be fine. 24kW is ~200kbtu.
I'm surprised at how little power swim spas require. A friend just put one in and it has a 4kW heater. That thing must be running most of the time in the winter. The same heater in a hot tub with 1/8 of the volume cant keep the temperature up when open (~1 to2 degrees down per hour) and only heats a couple degrees an hour when closed. I thought swim spa would have had at least 10kw and probably gas heat.

The one nice surprise that came out of my quote was that I did need a larger gas supply to the house, and was told that Enbridge would do it at no cost. Apparently they're happy to provide you with a means to use more gas.
Win-win for them. You get to use more gas….and the next owner…and the next….for generations for a few thousand $.
hydro is the same way, if you want to go 100amp to 200amp OVERHEAD, no charge on their part for the transformer to house connection. Of course, what ever upgrades you to at your house is on you.
unless its underground, many utilities use a third party contractor, and there is much involved, so they are happy to pass the costs on to you.
A friends house has 200 Amps to the meter base, with a 100A meter and panel. Seemed strange. Previous owner must have wanted to save a few dollars. He added swim spa and hot tub which together can draw close to 100A so he is planning on upgrading soon.
