I'm gonna commit to this. How does this work? I looked and according to the Internet TenneT is the sole operator of the national electrical grid in the Netherlands. Do you have 52 power lines running to your home? What do these companies do if they don't actually produce the electricity or operate the grid?
I have precisely one power company that services about 5 million residents here where I live. No other options. This is the case for almost all Americans as far as I'm aware, outside of a few specific municipality-run power organizations, but those are exceedingly rare.
