If I were a senior executive at an investor-owned utility (IOU), I would be more than a little nervous about the spread of Renewables, and grid-tied distributed energy generation sources in general. What would happen to the integrity of my operations if these proliferated in dense clusters in my service areas, and over which I exercised limited control? Can I co-opt them or are they competition? AMI, SmartGrid, and "cap and trade" regulations are innovation enough, I might think, do we have to accommodate distributed generation too?
