Weekly average prices in the main European electricity markets declined during the third week of September, with Italy the only exception. The British market recorded the sharpest drop, at 23%, followed by the Nordic market with a 22% decline and Belgium with 19%. Prices also fell by 17% in the Netherlands and Germany and by 14% in France. Portugal and Spain posted the smallest decreases, at 3.8% each. In contrast, the Italian market recorded a 2.5% increase.
Despite the declines, weekly average prices remained above €130/MWh in most European markets, except for the Nordic market, which recorded the lowest average at €81.46/MWh. Italy registered the highest weekly average, at €215.82/MWh. The Belgian and Dutch markets averaged €141.42/MWh and €139.11/MWh, respectively. Across the other markets analyzed by AleaSoft Energy Forecasting, weekly average prices ranged from €131.75/MWh in France to €135.25/MWh in Germany.
Daily prices were high across most European markets at the beginning of the week, exceeding €200/MWh in Germany, France, Italy, Great Britain, Belgium and the Netherlands. On Monday, September 14, the German market reached €256.55/MWh, the highest daily average of the week among the analyzed markets. Belgian and Dutch prices also exceeded €229/MWh. On the same day, the French, Portuguese, Spanish and Nordic markets recorded their highest daily average prices since December 2022. Germany and the Netherlands reached their highest levels since December 2024, while Great Britain recorded its highest price since January 2025. Italy, meanwhile, recorded prices above €200/MWh from Monday through Saturday of the third week of September.
From September 19 onward, prices fell sharply across most markets. On September 19, the British market recorded a price of €31.24/MWh, while the Nordic market reached €9.71/MWh. On Sunday, September 20, Germany recorded €21.75/MWh, while the Nordic market fell to €8.59/MWh, the lowest price of the week among the analyzed markets. Higher wind power generation, combined with lower demand in some markets, contributed to the broad decline in electricity prices. In Italy, however, lower wind generation and elevated gas and CO₂ allowance prices contributed to the increase in electricity prices.
For the week beginning September 21, AleaSoft Energy Forecasting expects electricity prices to increase in most of the analyzed European markets, driven by lower wind power generation. In contrast, prices are forecast to decline in Italy, where wind generation is expected to increase. Gas price developments will also remain an important factor influencing electricity prices across Europe during the fourth week of September, AleaSoft reports.
