The compensation for those who have photovoltaic Power Systems is "net metering". This means that if they generate a thousand kilowatthours in a month and their house consumes a thousand kilowatthours that month then they pay for zero kilowatt hours. However they do pay a monthly connection fee. Everyone pays a monthly connection fee.
In Florida the reason they are told not to produce power with their photovoltaic system is so that they do not backfeed the power grid and kill lineman workers and others who accidentally come in contact with power.

After reading most of the posts about the KCC decision I haven't seen anything on power losses during transmission of electricity. I'm a retired electrical instructor. The following statements are facts, not opinion, about electrical power distribution.
Small scale "photovoltaic" production of electrical energy and transmission of that energy to the power lines "at the point of usage" is a win-win situation. Both the home producer operating in a "net metering" agreement and the power company stand to gain with this situation. Here's why.
Fact 1:
FLOW
One of the variables in electrical "power" is called current. Current is the "rate" of "flow" of electrons through the transmission lines. As power usage increases, electron flow increases.
Fact 2:
resistance
Transmission "lines" offer resistance to the flow of electrons. The farther from the generator, the greater the "line resistance".
Fact 3
power losses
As electron flow increases, power losses in the lines increase by the square of the current flow times the amount of resistance of the power lines. Power companies go to great expense to limit power losses in their transmission lines by sending their power at a higher voltage and lower current.
Fact 4
solar intrusion
(approximate average)
As the sun comes up people begin using more power and photovoltaic systems begin producing power. When the Sun is directly overhead, photovoltaic systems are producing their maximum power. Power companies are experiencing their greatest line losses when power consumption is at it's greatest. Remember the calculation is the square of current flow time's the resistance of the power lines. At this time most small home solar systems are producing more power than they are using. This excess power is going to the closest power users in that area. (Path of least resistance) This "local" power production during the heat of the day actually helps power companies overcome losses during the highest time of loss of power transmission
Fact 5:
less energy lost
The power company loses less energy (less power) because of home systems. In effect they deliver power to homes nearby with practically no power loss because they get to charge for the photovoltaic power produced and delivered by a neighbor.
Fact 6:
The home photovoltaic electrical producer draws energy back from the power grid when it is supplying less power and therefore the power transmission losses are less for the power company.
Fact 7:
On a monthly basis, overproduction of power by the "home PV system" is power given to the electrical distribution system owner!
