This article frames power grid integration across the European continent as a solution to unpredictable power production from wind power for each country. This makes less sense when you factor in that the wind is highly correlated in nearby countries. The ones that are the easiest to import power from. Long distance power export is also lossy. Regulating power is hard to find now and will be even harder in the future as more production goes towards wind and solar.
