It does have a decent, modern baseline grid running at 220v (EU standard). This is more amenable to EV than US 110v, but otherwise insignificant. A nontrivial portion of the base demand is supplied by hydroelectric dams, thus renewable, some old coal plants as generators of last resort, largely being replaced by natural gas plants for environmental and efficiency reasons. A new nuclear plant is going online in the next few years in Sinop.

I don’t think load created by EVs would make a significant difference. It’s a developed country connected into the European grid, if it can’t generate it’ll buy from its neighbours and sell to its citizens at a premium.
