You’re missing the OP’s point: each and every customer PAYS for exactly what they use, plus most utilities charge a connection/service fee just for the “privilege” of paying that company to run itself responsibly and supply what they contracted to do. It’s not the consumer’s fault the electric company is mismanaged! There is a fairly easy way to see how much average demand there is and plan accordingly.
One of the things that really chaps my heinie is when new subdivisions are put up, and because the municipality now has to expand their water/sewer/roads/etc services, rather than charging JUST the new subdivision property owners for their new benefits, EVERYONE including those who may have lived in their houses for 30-50 years now suffer increased rates, even though they do not receive anything new, no benefit to them or their properties! You want new and fancy, you pay for new and fancy.
That new 120+ home subdivision out on the outskirts of town, which will likely be filled with people from outside the current county/municipality and therefore have no skin in the game yet, are now getting brand new utilities that their not-even-yet-neighbors are going to pay for in perpetuity. It’s

IMO, and why I live in the country with a well and septic. I’m good with paying for only what I use.
