Europe Sees Record Hours of Negative Electricity Prices in Q1 2026 Due to High Renewable Output

Negative electricity prices on the Iberian Peninsula reached a new all-time high in the first quarter of 2026, as wholesale market prices dipped below zero due to supply outstripping demand. Spain recorded 397 hours of negative electricity prices between January and March 2026, a sharp rise from the 48 hours in the same period of 2025.

Portugal hit 222 hours of sub-zero prices during those months, according to analytics firm Montel as reported by Euronews.

Most negative prices occurred in April 2026, linked to a spike in solar generation from longer daylight periods. Blustery conditions across Europe boosted wind energy output, further increasing supply beyond demand. 05 per megawatt-hour, data from Spanish consultancy AleaSoft Energy Forecasting showed.

85 per megawatt-hour on that same day. 46 per megawatt-hour, both also the lowest since October 2025. In France, hours with sub-zero pricing nearly doubled in 2026 compared to 2025, and Germany experienced a 50 percent increase, based on a Bloomberg analysis using data from Epex Spot SE.

In Europe’s day-ahead market, energy producers submit offers on how much electricity they will sell at what price. Generators underbid each other to avoid curtailment, driven by subsidies or contracts that make operation profitable even at negative rates. 67 billion, by turning down wind turbines and paying gas plants to switch on.

Europe’s grid investment has risen 47 percent over the past five years to about €70 billion annually. 5 million households across Europe, according to energy think tank Ember. The grid, designed for central plants, struggles with remote wind and solar sources that cannot always reach demand centers.

1 gigawatt-hours of new battery energy storage systems in 2025, marking 12 consecutive years of record growth. To meet 2030 targets, the EU needs to scale battery storage toward 750 gigawatt-hours within the next five years. Five EU markets accounted for more than 60 percent of new capacity in 2025, led by Germany and Italy, with Bulgaria as the fastest-growing market in third place, followed by the Netherlands and Spain.
