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,

Greetings Esteemed Wrenches,
My company was recently tasked to engineer a PV project in Alabama. We sat down for a meeting with all of the local big-shots. They proceeded to let us know that we are not allowed to feed any excess PV power onto their grid, production cannot exceed demand. I am hoping that y'all might be able to steer me towards a contactor assembly or device that would detect reverse current flow, trigger the contactor, then open up the inverter AC output circuit. The service is 3-phase, 208 volt. The maximum current we intend to introduce is 70 amps, continuous.
Appreciate your advice,
Karl Jaeger
