Is a Generator Home Insurance Discount Worth It?
Usually, if the discount offsets the generator's added liability risk and installation costs, it's worth asking your insurer to apply it.

Why your renewal went up without a claim
A generator discount is a side issue here. Renewal prices usually rise from rebuilding costs, local claims in your area, or how the insurer is pricing your whole book of policies that year, not from anything you did. None of that shows up on your declarations page, so it can feel arbitrary even when it isn't. What you can check is whether a standby generator was ever reported to your insurer, since a permanently installed one can raise liability coverage for things like carbon monoxide or fuel storage, and some insurers offset that with a small discount if you ask. If the increase still looks out of line with what changed, that's a reason to compare other insurers, not a reason to expect this discount to fix it.
A generator discount might shave a little off the bill, but it won't explain or undo an increase tied to rebuilding costs or claims across your area. If your renewal climbed without anything changing at the house, the more useful move is checking what another insurer would charge for the same dwelling coverage and deductible right now.
How does a generator affect what the policy covers
A generator changes two things on a policy, not just the price. One is liability, since a permanently installed standby unit runs on natural gas or propane and carries some risk of fire, carbon monoxide, or fuel leaks that a portable unit in the garage does not. The other is the generator itself as property, which falls under dwelling coverage if it's wired into the house, or personal property coverage if it's portable and stored separately. Your declarations page should reflect whichever one applies, and if it doesn't, the coverage might not match what's actually sitting in the yard.
Installation matters more than most homeowners expect. A standby generator wired by a licensed electrician to code, with proper clearance and shutoff valves, is a different risk than one installed without a permit. Some insurers ask for proof of professional installation before they'll extend coverage or apply a discount, since an unpermitted setup raises both the fire risk and the odds of a claim being disputed later. If a generator was installed by a previous owner or a contractor years back, it's worth confirming the paperwork still exists somewhere.
Portable generators carry a different set of concerns. They're usually covered as personal property up to the policy's limit, but the fuel stored alongside one, often several gallons of gasoline, can affect how an insurer views the overall risk on the property. Some policies cap how much fuel can be stored without a separate endorsement. This rarely changes the premium by much, but it's the kind of detail that surfaces during a claim if a fire starts near where fuel was kept, so it's worth knowing before anything happens rather than after.
None of this is a reason to keep a policy that's gotten expensive. A generator, whether portable or standby, is a small piece of the coverage picture next to dwelling limits, liability limits, and deductible, the things that actually drive most of what a policy costs. If the renewal number is the real problem, comparing what other insurers would charge for the same house and the same generator setup tells you more than any one discount will.
What should be done with the generator when switching insurers
Moving to a new insurer doesn't mean the generator falls off the policy or needs to be re-explained from scratch, but it does need to be reported the same way it was, or should have been, with the current one. A new insurer will ask about permanent fixtures during underwriting, and a standby generator wired into the house counts as one. Leaving it off the application to keep things simple can cause problems later if it ever factors into a claim, even one unrelated to the generator itself, like a fire that started somewhere else on the property.
The paperwork from the original installation becomes more useful at this point, not less. A new insurer evaluating whether to extend coverage or apply a discount will want to know the unit was installed by a licensed electrician, to code, with the clearances and shutoffs a standby generator requires. If that paperwork exists, having it ready when applying for quotes saves a step. If it doesn't, it's worth finding out before switching rather than after. Some insurers will ask for it before they finalize coverage.
Portable generators are simpler to carry over, since they're personal property and usually just get listed or valued the same way other belongings are. The detail that sometimes gets missed is fuel storage. If several gallons of gasoline are kept on hand for the generator, a new insurer may have different rules about how much can be stored without an endorsement than the old one did. It rarely changes the quote by much, but it's worth asking about directly rather than assuming the new policy treats it the same way.
None of this should slow down comparing quotes. The generator is one line in an application, not a reason to stay put if the renewal number no longer makes sense. Getting quotes from other insurers for the same dwelling coverage, the same deductible, and the same generator setup shows whether the increase was tied to the house or just to where the policy currently sits.
Before you decide anything
Pull your declarations page and check how the generator is listed, then get a quote from another insurer for the same dwelling coverage and deductible. That comparison tells you more than the discount ever will.
