Hi Karl,
Whether it's worth pursuing or not, I believe their stance is in
violation of PURPA. I'm not an expert but I know others have won court
cases over it. It is left up to the State to administer however I do
believe. DSire.org shows no net metering support in Alabama. I
imagine someone else on the List knows more than I.
But it sounds in this case like the technical fix is more prudent -
Everything has it's season.
Best of Luck,
Jeff C.
