    This is exactly the issue. Nuclear is necessary in the long term for a clean grid, however it will take much longer than as well as take investment away from renewable projects - which could achieve net zero more quickly than nuclear.

    We should be going hard on current renewable technology, build out a massive excess (to account for reduced generation, the wind is always blowing somewhere and the sun shines throguh the clouds), and then once we have met all our energy needs from clean energy and phased out fossil fuels we can focus on fortifying the grid - in particular at that point we will need large turbines with lots of rotating mass, for voltage and frequency stability, which is a perfect role for nuclear to fulfill.

      One of the problems that we have is that a big chunk of the country for a month don’t have a single ray of sunshine due to polar nights. The problem is that that is when it’s complete darkness leading up to the point and going out of it takes time as well so solar is not an option at that time of the year. On top of that most of the land is “disputed” by indigenous people (don’t mark my words it’s a very touchy subject I don’t know how to express it better) or it’s a nature reserve area so wind farms are out of the question. So the only thing we have left is hydropowered electricity which isn’t clean at all as it destroys the natural course of the river up stream, destroys the river beds down stream and extremely reduces the fish populations as well as any greenery relying on the reliability of the rivers.

      With that said if we simplify it a bit about 46% of Swedens total energy production comes from the northern hydroelectric plants and wind farms and because of lacking infrastructure it can’t be transferred efficiently to southern Sweden where most of the consumption is happening. Of these 46% about only 30% is currently used but more companies have decided to establish their production in thr northern region due to the surplus of energy in this region.

      Southern Sweden on the other hand gets a lot of their energy from unreliable wind farms as well as nuclear energy. However due to the layout of the land hydroelectric is only viable in some places which have already been exploited. We can only install so many wind farms until it affects quality of life to the people and animals living nearby. On a good day southern Sweden is having a net zero energy production and consumption. Those days are fewer and further in between. Currently since closing a reactor two years ago we have had to reinstate an oil burning facility as well as buying unclean electricity from abroad to keep up with demand.

      So investing in nuclear to stabilise the production is one of very few options we currently have.

      It’s either that or moving either part of the population or factories to the northern part which is not really viable or sustainable eitherm

        It sounds like the biggest issue is transmission, you need high capacity transmission lines between the north and south. That way, you could not only use more than the 30% currently, but expand that capacity. Also, transmission between neighbouring countries could help.

          Currently we sell the surplus in the north to Finland and Norway as well as to Denmark and Germany in the south when we are over capacity.

          What we would need is a better connection between north and south but that hasn’t been a priority until now and it’s 30 years too late.

            Nuclear takes a hell of a lot of subsidised state money, and that pot of money only ever grows. Renewables don’t need state money, they’re profitable on their own. Renewables will grow readily if the transmission infrastructure is there, and moreso if the planning process capacity is expanded (hire more civil servants), let alone if rates were subsidised anywhere near the same level as nuclear.

            The best case scenario would be the government itself building state-owned renewable infrastructure, where the profit from selling cheap electricity on the commercial market would come directly back to the community. Most wind farms are owned by one company and managed & operated by another, with the turbine manufacturer providing turbine services. There’s no reason the government couldn’t be the owning company.
