Yeah, I was just wondering whether the gas pipe will deliver the volume
that you need to keep the genny running.
They might not have planned on your proposed consumption when they laid
the pipes.

Are you getting the NG delivered by pipe?

I am assuming a BTU of fuel will make so many Wh of energy.

That would cost me *$35* from the power utility.
A gallon of diesel is abou $3.25 around here. 139000 btu.
Diesel then is about $23 per 1M btu.
However diesel engines are only 30% efficient so it will cost me *$76*
in fuel to make that 292.3 kWh
If that assumption is approximately correct:
I pay about $7.80 per decatherm in the winter for NG. A decatherm is
1
million btu
About half that in summer.
$7.80/.3= *$26*/293.3 kWh for NG not considering depreciation and
maint
of the generator.
It seems to me that NG is the hands down fuel cost winner? Anyone see
mistakes in this?
