One important aspect of this is battery capacity can be safely placed at the grid edge. Power infringement is built to handle the capacity of the peek days but statically these peeks only occur once in a blue-moon. By adding battery capacity at the edge of the grid significantly less long distance transmission infrastructure is is needed and the grid can be balanced in a much more targeted way.
