Electricity prices fell across most major European markets in the week starting April 28, driven in part by increased solar energy production, according to AleaSoft Energy Forecasting.
France and Italy both set new daily solar generation records during the week. France produced 135 GWh on April 30, while Italy generated 150 GWh the same day. Germany also saw a milestone, with 397 GWh of solar output on April 28—its highest for any April day.
These records helped push weekly electricity prices down in several countries.
AleaSoft reported average prices under €65/MWh in all tracked markets except the UK and Italy, which recorded €76.88/MWh and €80.91/MWh respectively. Spain and Portugal remained the lowest at €15.36/MWh and €16.50/MWh.
AleaSoft attributed the price drop to “a decline in weekly gas prices and fall in electricity demand” alongside high renewable generation.
However, the trend is unlikely to continue, with prices expected to rise again due to increasing demand and reduced solar and wind output.
Negative hourly electricity prices were widespread. On May 1, Spain recorded a new all-time low of -€10.00/MWh.
France also saw its lowest price since July 2023 at -€118.01/MWh, while Italy matched its minimum possible value of €0.00/MWh.
That week also saw a major blackout in the Iberian Peninsula. AleaSoft noted that hourly price alignment between Spain and Portugal dropped to 54%, compared to 84% the week before and 95% for 2025 up to the day before the outage.
