Not all that massive: 6% increase if all cars and vans (excluding e.g. big rigs and tractors) go electric, according to the Norwegian national grid institute[1] (in Norwegian). Some local grids will need an upgrade, but the national transmission and distribution grid can handle it if 'smart' charging solutions shift the bulk of the charging to happen at night and other low-demand periods.

Norway uses a lot of electricity even without EVs, so it's not a very large increase percentage wise. E.g. we don't have gas pipes to homes like some places in the USA, so stoves are all electric and a lot of heating is electric as well.
