In Spain they probably do because the government is heavily involved in the electricity production. It's not really a free market, and it didn't have to be. In fact I'd prefer it to be more in the government's hands then it is. But Spain is a country that's much more socialist than the US and as such I'm very happy to live here. For example when energy prices rose during the pandemic and the Ukraine war the government put limits on price increases and also lowered VAT.
