What kind of risk are you talking about?
The electrical network connecting all your federated renewable infrastructures is managed by one entity already, isn’t it? That’s the same kind of risk you describe.
I get why people don’t like nuclear power and there are many valid arguments against it but yours is not
The overall grid is managed by governments cross countries in Europe. The production is not. While the producers do have an obligation to provide enough electricity at all times, the consumer is free to purchase the electricity from any distributor they want. This creates a free market for pricing while keeping the production regulated. For a small country like Sweden, producing everything in nuclear would destroy the market mechanism on pricing, leaving then with a monopoly.
The risks towards energy production are stuff like war, natural disasters and terror. All of which have been relevant within the last ten years somewhere in the world and increasingly so. The only way to maintain a functional distribution of electricity in these situations is to have the production de-centralised.
I’m all for wind/solar expansion, but we shouldn’t underplay the challenges of keeping grid stability with pure renewables with the technology we have available today. As it stands, I think it would be great and borderline necessary to also expand nuclear power production alongside renewables for now.
For a small country like Sweden, producing everything in nuclear would destroy the market mechanism on pricing, leaving then with a monopoly.
Nobody except for maybe our far right party SD is calling for this, and the odds of us going this far backwards is close to zero. The amount of nuclear production needed to render all other means of production up here obsolete and uncompetitive is insane.
I don’t have anything particular against nuclear as a source of energy. I just don’t think it can done fast enough and in an economically feasible way. Even if they do make more nuclear plants, they are going to need something else in the meantime before the new plants can be ready if the forecasted increase is to be trusted.
