On November 3, 2018, wholesale electricity prices in almost all of Western Europe have leveled out, and only four EU countries have retained price independence. Among them was Poland with the most expensive current in the European Union.

The markets of industrialized central Europe, ie Germany, Austria, the Benelux countries and France, strongly integrate. The other strongly integrated group are the Nordic and Baltic countries. The Czech Republic and Slovakia as well as Hungary and Romania are also heavily burdened on the markets of Western Europe.

In Central Europe, Poland has the highest electricity price in the region. The other non-integrated country is Great Britain. Both on the London and Warsaw stock exchanges, electricity prices are not only least connected with the rest of Europe, but also the highest – in the UK exceeded PLN 285, and in Poland PLN 303 and was the highest in the entire European Union.
