Strong winds are driving German day-ahead power prices to their lowest level since June, with Saturday prices falling 53% from the previous day and nearly half those in France.
German power for Saturday dropped to 42.14 euros ($48.94) per megawatt-hour, according to Epex Spot data. French prices were nearly twice as high, an unusual reversal of the typical pattern, in which German electricity trades at a premium to French prices.
Germany's expanding fleet of wind and solar farms can produce large volumes of low-cost electricity when weather conditions are favorable, weighing on wholesale prices. Prices can rise sharply when renewable output declines and the country relies more heavily on fossil-fuel plants and imports.
France is meanwhile grappling with reduced nuclear availability due to heat-related issues and extended maintenance, increasing its reliance on gas-fired power generation.
Strong solar output is also pushing prices lower in both countries around midday. German power prices are set to fall as low as minus 19 euros per megawatt-hour on Saturday, according to Epex Spot data, as renewable generation is expected to surge and demand remains relatively low.
