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.
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.
The best time to plant a tree…
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.
Funnily enough, projects for green steel and the construction of new massive factories in Northern Sweden mean that the power surplus is expected to be gone by 2030. We need more electricity production, from all carbon neutral sources being built everywhere, ASAP.

Exactly. We need it quickly.
Renewables are here now and can be deployed quickly. Nuclear takes time and is often heavily delayed and over budget.
We need nuclear as well, but we need renewables first, to build capacity as quickly as possible. We need a huge excess of renewable capacity, to account for times when the full capacity isn’t available. We shouldn’t expect to be using the full capacity at any time.
Once we’ve phased out fossil fuels, then nuclear will be important. But right now nuclear only serves to sustain our dependency on fossil fuels.

The two largest economies with the low reliance on fossil fuels for energy (Sweden & France) get significant portions of their energy production from nuclear power. Iceland relies on geothermal, and the others (Tajikistan, Switzerland, Costa Rica, Norway) have lots of hydro capacity, which are all excellent, but also largely dependent on geography.
I don’t have figures to hand, but I’d gladly dig into them with you, if you have suggestions.
Sweden does have some amount of fossil fuel generation. The article claims 3 nuclear plants provide 30% of the country’s needs right now, and says the target being set is for 10 new nuclear plants over the next 20 years. In 2045 (~20 years), demand is predicted to be double that of today.
If we assume all current nuclear plants will close and all new plants will be 20% larger, that means these 10 new nuclear plants will fulfill 60% of predicted demand in ~2045. Again, I’m happy to review actual numbers - I imagine most if not all of these 10 plants are at least in early design proposal stages, so there are some actual MW numbers to be crunched.
I think keeping Sweden’s nuclear at about 30-40%, while investing more into a large excess of renewables, would allow fossil fuels to be switched off more quickly. This would still mean investment and growth in nuclear, with maybe 5 or 6 plants (if the 3 existing plants have to close), but would get rid of fossil fuels more quickly.
In maybe 10 years’ time, with fossil fuels well and truly on their way out, that would be a better time to expand nuclear.

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.
