"According to Eurostat, we pay €0.2246 per kWh here which is 22% higher than in the UK." Unmitigated drivel. Current UK prices are, i pay, euros €0.39 per kWh, charge before Government subsidy is euros €0.59 per kWh.
Those numbers look like they could be about right for 2020/2021, but using them in a 2023 article is meaningless given the effects of the war in Ukraine on gas and electricity prices. I don't know how much Portugal's grid depends on gas, but I could believe that it's less affected by gas prices than the UK grid is.
