Here in NL they have a decent system if you ask me. Infrastructure for power is owned by TenneT, a semi-government organisation. Then power is supplied by private companies, from whom you can choose any one you want (aka the cheapest/greenest one, depending on your wishes). They then supply power to the national grid, so you’re technically using power from all companies, but paying your share to the one you have a contract with.
