Your utility bill has very little to do with the cost to generate electricity and everything to do with the cost to deliver it.
I’m an investor in a large manufacturing facility that happens to have natural gas wells on the property. We actually bought rights to take delivery to supply gas and run generators. The cost savings was staggering, even paying full cost to the royalty owner and operator. (We pay the same as the pipeline.)
Lots of people and equipment between generation and use, so I can see your point. You guys cut the middle man out, pretty sweet. Guess the big bosses got a nice bonus for that move.
