It's the same for the grid in Sweden (Svenska kraftnät), also how optic fiber is deployed here in Stockholm, the costly infrastructure was developed and is maintained by the government, private ISPs can lease out capacity but aren't the ones maintaining it. That avoided the costly deployment of multiple similar infrastructure per provider like you see in the US, where corporations cornered some markets and made the barrier of entry so costly that they became de facto monopolies.
Ah, now I get that. Adding my two cents on this discussion: if there is a profit motive for any modern basic human need (food, shelter, energy, communications, healthcare) it should be very well regulated to protect society. It may sound paternalistic when seen with a neo-liberal eye to it but I have developed a firm belief that neo-liberalism has utterly failed as a societal experiment to move us forward.
I replied to (a comment) and tried to contrast how a state owned power grid can still have profit models attached and function both technically and for it's intended customers.
(Like most hospitals in the US, by the way, coming back to the original "There shouldn't be a profit motive attached to basic services like electricity, policing (private prisons), or medicine" comment.)
My understanding is that they're registered as a charitable organization, not a non-profit. These terms are often used interchangeably, but from a tax and earnings perspective they mean different things. This is often further confused with not-for-profit organizations, which is yet another thing.
