   Hello, and thanks for replying.  Those are certainly reasonable guesses.   
     Textbooks are great on theory but often come up short on application.   
   My take on this would be since the electric utility would know the   
   distribution main and branch MV line interconnections from a substation   
   and the reactive volt-amperes at the load (industrial plant), they could   
   just go back up from the aggregated loads to some convenient point on   
   the distribution line, and knowing the transmission line characteristics   
   (resistive loss per mile, etc) the amount of parallel capacitance   
   required can be determined.  Sincerely,   
   --
