Are you saying it could very well be cheaper to generate our own electricity from a NG genset than purchase it from the grid?

I'd do this tomorrow if true.

Here's what I pay:

Electricity
$12/mo connection charge
$0.08041/kWh

Gas
$7/mo connection charge
$1.01057/therm

There are 29.3001111 kWh to a therm. At a 100% conversion efficiency, I would pay $0.0344903129053323/kWh with gas.

If my math is correct, I would need to convert gas to electricity at 43% efficiency to break even on price, ignoring the monthly fixed costs.

I'm thinking 43% efficiency isn't doable, and even if it was, the maintenance costs would eat up any small savings.

You would need a battery to supply peak demands. Perhaps the genset would only run when the battery depletes to a certain threshold; running at peak efficiency whenever it is automatically started.
