This is David Dixon. I am not in Mueller, but I do have a recently commissioned 8kw installation (waiting for 1st AE bill) that I am very excited about. I have a PV installation company, Native, here in town. I am currently very engaged with Solar Austin and efforts to lobby City Council on increasing the integration of distributed energy (solar) into the generation mix.
I would be interested in joining a meeting of concerned folks to help formulate some talking points at City Council. I can tell you that harping on Leslie Libby's group is not the path to getting anything changed. Her group is your ally. This issue will need to be taken to Council as Austin Energy upper management is not excited about customer owned solar and there are many issues at play here - some not obvious at first blush.
At the moment, the issue for me is securing solar budget for the next fiscal year (Oct), but I see the Value of Solar Tarriff (VOST) as something that we get organized on now and then bring concerns to council in the next couple months. You may or may not be aware, but AE is "re-evaluating" the VOST - presumably to strip out some of the value. Getting in front of this issue will be important for us all.
For those of you that love this stuff - here is some recent discussion with council last week about the solar budget.
Item 4, part 1 and 2 cover the solar rebate
