Ian:
I don't understand: price is price. If rooftop solar is cheaper than coal then
it will be installed and the base load reduced.
Once there is enough of it--Germany has this issue at 3% solar--the
distribution system has to be changed to accept multipoint input and storage
added. Which the Germans are currently planning.
That is what one can see happening today. Why do want to spend bajillions on
pipe dreams?
