Please do not forget that most of the household price difference comes from taxes. This is also said in your own source [1]:
> Taxes and levies make the biggest difference. Their share climbed steadily, from 25.6% in 2011 to 40,3% in 2020. These values vary greatly from one country to another, with rates as high as 66% in Denmark and 53% in Germany.
I.e. in Germany, 90% of the Stromsteuer is used to fund the government pension system. So you cannot really compare the household prices between countries and make conclusions about the efficiency of their electricity policies, because a lot of countries just opt for another scheme of government financing through taxes on stuff such as electricity (or gasoline taxes for example, which is also used to fund pensions in Germany).
