Oh of course, grid scale energy is never for the "normal person". The point I am making is established fossil-fuel based energy majors do not want any pip-squeak independent startups to start siphoning profit off from their system or possibly making it more efficient or cheaper for the consumer. Vertical integration of regional monopolies is the name of the game.
