I have family living in Belgium. Their bill for gas and electricity went up from 145 EUR/month two years ago, to 281 EUR now. So these triple, quadruple or more bills are not normal. Prices are up between 100 and 150%. Most energy companies have long term contracts at much lower prices than the spot market. In all articles journalists use however the spot market (TTF) prices which are just for immediate and urgent deliveries. That's more spectacular and better for selling nespapers. These prices are not realistic for the situation in EU.
The average rise in energy cost for a household in Europe during recent months is 80% (or will be 80% as of early October) according to sources tracking the increases. Still not good -- especially if the bills will further rise in the winter months, but not 3X, 4X for households. Business customers in unregulated energy markets in Europe where they can select their energy provider with many using spot market pricing are the ones bearing the brunt of the large increases.
