This is fairly liberal use of the term "decentralized." Building many more nuclear plants is still "decentralized" in that some of them can be offline and the system still works. Major solar and wind installations are typically concentrated in similar generating stations as nuclear plants are. Many more people will likely have solar on their homes, but it's not like wind and solar is going to lead to a purely decentralized grid where every small community is generating their own electricity. There will always be large scale generating stations for the bulk of grid electricity.
