1. An electrically dynamic system comprising:
a first pane of transparent material;
a second pane of transparent material;
an electrically controllable optically active material positioned between the first pane of transparent material and the second pane of transparent material, the electrically controllable optically active material being positioned between a first electrode layer and a second electrode layer; and
a power transfer assembly comprising:
a window balance assembly including a first portion configured to be fixed in place, relative to at least one of the first pane and the second pane, and a second portion configured to be movable relative to the first portion;
a pivot bar conductively coupled to the second portion of the window balance assembly; and
an electrically conductive pathway between the window balance assembly and at least one of the first electrode layer and the second electrode layer.
