Weekly average electricity prices declined across most major European markets during the third week of September, with Italy the only market to record an increase. Great Britain posted the sharpest decline, at 23%, followed by the Nordic market at 22% and Belgium at 19%. Prices fell by 17% in both the Netherlands and Germany and by 14% in France. Portugal and Spain recorded more moderate decreases of 3.8% each, while the Italian market saw prices rise by 2.5%.
Despite the weekly declines, average electricity prices remained above €130/MWh in most European markets. The Nordic market was the exception, recording the lowest weekly average at €81.46/MWh. Italy posted the highest average, at €215.82/MWh, followed by Belgium at €141.42/MWh and the Netherlands at €139.11/MWh. In the other markets analyzed by AleaSoft Energy Forecasting, weekly average prices ranged from €131.75/MWh in France to €135.25/MWh in Germany.
Electricity prices were particularly high across major European markets at the beginning of the week, exceeding €200/MWh in Germany, France, Italy, Great Britain, Belgium and the Netherlands. On September 14, Germany recorded the highest daily average among the analyzed markets, at €256.55/MWh. Prices in Belgium and the Netherlands also exceeded €229/MWh. Meanwhile, France, Portugal, Spain and the Nordic market reached their highest daily average prices since December 2022. Germany and the Netherlands recorded their highest levels since December 2024, while Great Britain reached its highest price since January 2025. Italy maintained prices above €200/MWh from Monday through Saturday.
Prices fell sharply from September 19 onward across most markets. Great Britain recorded a daily average of €31.24/MWh on September 19, while the Nordic market reached €9.71/MWh. On September 20, Germany recorded €21.75/MWh, while the Nordic market fell further to €8.59/MWh, the lowest level of the week among the analyzed markets. The decline was supported by higher wind generation and lower electricity demand in some markets. Italy followed a different trend, as lower wind generation combined with elevated gas and CO₂ allowance prices contributed to higher electricity prices.
For the week beginning September 21, AleaSoft Energy Forecasting expects electricity prices to increase in most of the analyzed European markets, mainly due to lower wind power generation. Italy is expected to move in the opposite direction, with prices forecast to decline as wind generation increases. Gas price developments are also expected to remain an important factor influencing European electricity prices during the fourth week of September, according to AleaSoft.
