Especially since the Swedish power company - Vattenfall, is 100% owned by the Swedish state.

I'd say other countries should take note. But privatization of infrastructure assets is a lie that has been sold to millions across the world

You mean Svenska Kraftnät (SVK) instead of Vattenfall, they're the ones making money from electricity distribution. Vattenfall is an electricity producer, it's not responsible for this kind of distribution across borders. It is responsible for some distribution within Sweden (regionnät), but there it is not the only player. SVK on the other hand is 100% owned by the state.

That sounds strange, when there's a shortage of power, don't the higher electricity prices go mostly to the energy producers, in order to create incentive to increase production and start up more expensive generation forms?

That's true but the poster you replied to was talking about distribution so I assumed that was what you were talking about as well.

Vattenfall is not the only Swedish producer. Not even the biggest one!

Or the very least, be used to build new energy infrastructure and generation.
