I can explain a case I know of.. Duke Energy is the regular provider. If too many people were off-grid with solar, they the cost of providing power to everyone becomes harder to justify.. less people share the expense of maintaining the infrastructure in a hurricane zone.
At least that is what I see as the justification for the following:
Get this.. you put a big solar system on your roof.. enough to generate enough to handle your needs and more to sell back to Duke Energy... they buy it at pennies on the dollar.. it is in the contract. They buy it at 6 cents (I forget the real number) and your cost to buy energy is more than double that.
And your solar is not used for your home. That is, you generate power FOR Duke Energy.. at that low rate.. and your usage is counted at the higher rate.
Yeah.. you can still more than break even with enough outlay. But there are rules against you putting in a battery system and running your home off that.. you have to buy through Duke Energy (I am sure other providers have similar deals elsewhere).
I think of New Jersey's fear of electric cars where they used the gas tax to pay for a lot of stuff.. allegedly the highways.. but really any governmental use they elt like in Trenton.. Monorails, etc. Less people buying gasoline meant less tax revenues at the pumps. Reduced ability to maintain roads (if those funds were really used for that).
So in Florida terms, more solar is good... until it threatens the established infrastructure with lower revenues.
You guys should also realize that too much energy is a problem too. I remember hearing about what seemed to be a strange effort in Kuala Lumpur, the capital of Malaysia. They used a lot of hydro and the problem was one of balance.. high usage during the day, less at night, they had problems keeping a balance so the amount they produced better-matched usage... so they gave away free energy at night and encourage office buildings to install outside lights that would be on all night.. leave light son in buildings, etc. Many stores had open doorways to the street with a wall of AC creating a thermal barrier to the oppressive heat and humidity outside. I found that odd and also fun.
