Just before closing on a house outside Columbia, South Carolina, a prospective buyer concerned about hurricanes went to Reddit to ask about power outages and backup generators.
Most replies favored some kind of backup power, though many commenters didn't think that meant paying standby-generator prices. Even a homeowner who sat through a 75-hour outage after Helene said that experience still did not justify spending $10,000 or more.
Here's what to know
In a Reddit thread on r/Generator, the buyer asked residents near Columbia how often outages happen, how long they usually last, and what sort of backup system would make the most sense. The poster added, "FYI, the house already has a natural gas line, so I could use that as fuel."
An Upstate commenter used Helene as the clearest example of a severe outage, saying, "We didn't have power for 75 hours which was unheard of." That same person also called it "a once in 100+ year storm" and said that, outside that event, outages usually lasted just a few hours because of branches on lines, car crashes, or transformer issues.
Rather than treating that as a reason to buy a whole-home standby system, several commenters pointed to cheaper backup options. The Upstate homeowner said an interlock on the panel was "$800 well spent!" Another person in the thread estimated that an NG outlet, an electrical inlet, an interlock, and about a 5-kilowatt generator could total roughly $1,500 to $2,000.
Using a basic portable-generator setup, based on the prices commenters discussed, could cost thousands less than the $10,000 to $20,000 range they tied to standby systems.

More background
Commenters also stressed that outage risk can vary a lot by location and grid setup. One resident of West Columbia said some homes in the area might lose power for only a few hours in a normal year, while others could be without it for a week every few years.
Hurricanes were not the only concern people raised; ice storms came up repeatedly as another likely cause of extended outages. A commenter in Aiken said Helene left them without power for five days, and after reviewing outage patterns over 15 years, they chose a battery backup charged by a 4-kilowatt generator instead of a full standby unit.
Some advice focused less on equipment and more on learning the property's specifics. One commenter said buyers should ask neighbors and sellers because homes on priority circuits near critical facilities such as hospitals may be restored faster, while neighborhoods with underground lines can have fewer issues than nearby areas fed by overhead lines.
Not everyone in the thread leaned toward smaller systems. An Easley homeowner said brownouts and power outages were enough to justify installing a whole-house generator, which had run three times, mostly in summer when air conditioning was especially important.
What can be done?
The thread's most repeated recommendation was to start with the home's local outage history before buying anything. Commenters said buyers should ask neighbors, ask the sellers, and review the electric provider's outage or uptime data to decide whether that specific location really needs a major installation.
Many commenters also said the system should be sized around necessities instead of the entire house. One recommended enough capacity for "any fridges and freezers, a window/portable AC or heater, a TV and modem, a fan or two, and any chargers," so food, basic comfort, and internet access could be maintained without the cost of full-home coverage.
Another recurring point was fuel flexibility. One commenter said that because freezes or storms can interrupt natural gas service, a bi- or tri-fuel generator makes sense so it can run on natural gas but switch to gasoline or propane if needed. Another suggested storing a few 30- to 40-pound propane tanks, and the Aiken commenter said they keep enough gas and propane on hand for at least six days.
Standby systems still had supporters, but commenters noted that the real price can extend beyond the generator itself to include a pad, permits, maintenance, and service. For many people in the thread, those extra costs made a hybrid battery setup or a portable generator with an interlock look more appealing.
