re: Home Generators and Natural Gas
I'll tell you currently in Houma, there are A LOT of whole home nat gas units that aren't able to run full or even half capacity due to low gas pressure. My MIL is one of them. Guy in my neighborhood can't run his AT ALL. He's running a portable to get by. If there are alot of units in your neighborhood, you better hope you are upstream and not downstream.

ETA, I have a 20kw diesel unit and diesel has been a nightmare to find. So both options suck. And propane uses a metric frick ton I'm told. There's no perfect solution.

re: Home Generators and Natural Gas
my father in law convinced my wife it’d be too hard after a storm to move a wheeled unit, Plug in two lines, and flip four to six switches.

But I’m not in charge, so the generator guy is coming next week to sell an oversized unit that’s going to run everything, because my father in law convinced my wife it’d be too hard after a storm to move a wheeled unit, Plug in two lines, and flip four to six switches.


So who's calling the shots at your house? Is FIL paying for it?

Her, no. It wasn’t a hill worth dying on.

re: Home Generators and Natural Gas
Houma shut down its gas grid along with water after the storm. For what that’s worth.

Anyone here running a standby on propane? Currently weighing the difference now. Had a firman 11,000 explode yesterday and have a line going to my neighbors house while I resolve this issue.

I’d really like to get a big portable and use as a mobile whole home generator. I see generac makes a 17,500 watt portable, which would power my whole house, however those Cummins standby units are looking sweet right about now.

re: Home Generators and Natural Gas
i would never invest in a standby generator where flooding is an issue.

re: Home Generators and Natural Gas
If you want ot stay with the 5500watt portable type, the natural gas conversion carburetors are awesome...
best $200 investment, and no more gas lines.

Correction, it was a powerhorse 11050. Pretty sure it threw a rod on the exhaust valve. Blew out the crank case. Big flame. Loud bang.

re: Home Generators and Natural Gas
I'm well aware they shut down portions of the grid. In my specific area however it was never turned off completely. I know several Generacs that have ran since the initial power outage. They just have low pressure and can't run a load. That's why nat gas blows after a big storm.

I dont know anyone running propane. No idea how true it is, but I've heard they burn fuel at a much faster rate. And after a storm, I'm not sure how accessible propane deliveries are.

I do like the idea of the big portable units. I have a 20kw diesel on a skid on the side of house, but if I didn't I would seriously look into the feasibility of renting a trailer mounted diesel unit before a storm comes. Not sure what the cost analysis runs on that though. That way you have a service provider who isn't completely bogged down like these shitty generac dealers around here. My neighbor brought home a rental Miller welding machine from their jobsite to power his house and had United rentals come out and replace a faulty sensor on the water separator almost immediately after calling.

re: Home Generators and Natural Gas
Anyone know if Costco still has these Firman Tri-fuel generators? My 13yr old Briggs died. I’m going to make the drive to Lafayette this weekend if they still have them.

I was in the Baton Rouge Costco yesterday PM and they had some of the tri-fuel Firmans and a large number of Champions.

re: Home Generators and Natural Gas
I am in the process of a new build right now and we are installing a 30kw Cummins on propane. I don't have natural gas where we are building so it's not an option. Lacox told me that I would be looking at about 7 days on 500 gallons depending on load and auxiliary gas usage. Lacox was servicing customers here in Covington 2 days after the storm.

re: Home Generators and Natural Gas
I was going to get a 20-30kw Cummins diesel. But after looking at the price, I’d be fine just being able to run everything but my central air and just use 2 window units. So I’m getting a plug and the tri fuel and rolling that way.

man after rita and laura, LC area didnt really have any problems with low gas pressure. Thats surprising and sounds like Hoama wasnt doing proper maintenance.

re: Home Generators and Natural Gas
I think a big problem is that people should get a bigger meter when getting a Generac but they opt not to.

My neighbors in Houma had no issues with natural gas pressure. 1/2 Generacs died. The Briggs and Cummins units ran flawlessly.

re: Home Generators and Natural Gas
It was a unique combination of a boat load of leaks and an equal amount of nat gas standbys running. There was a staggering number of standbys put in Houma over the past 10 years or so. Some areas had gas turned off completely until the parish could isolate leaks. I know of 4 people off the top of my head that had to de-rate their engine by turning the gas regulator down. It was the only way it would run without surging. Sure they lost some Kw, but at least it ran.

So they are telling you roughly 7 days running that big of a generator on 500 gallons of propane, even with other appliances running. That's pretty damn good for a unit that big. Refill trucks were running two days after the storm here in Lafourche parish also.

No one seems to have info on the fuel efficiency of a standby on propane but the rumors, as stated on this thread, are that they are heavy feeders. I guess there's the feel of poor efficiency since a propane tank is limited, while NG typically isn't.
