I guess one could say that Norrland is like Sweden’s Montana or something like that.
Currently Norrland is receiving lots of business interest and investments. Northvolt is one example. H2 Green Steel is another. For the local population I believe this is very good news. It should give lots of job opportunities that will spill over to other areas such as service jobs.
Some reasons that are often cited why Norrland is a good location is the availability of clean energy from hydropower[0] and that there is also a high level of competence already when it comes to modern manufacturing methods.

[0] Totally different story in the south of Sweden where nuclear reactors have been decomissioned, and the energy availability seems to become more and more uncertain.
