Iberian Power Prices Turned Negative for 397 Hours in Q1 as Solar Output Surged

Summary
Spain logged 397 hours of negative electricity prices in January-March, up from 48 a year earlier, while Portugal recorded 222 hours, marking a Q1 record for the Iberian Peninsula.
Clear skies and strong sunlight lifted solar generation enough to push supply above demand, driving wholesale prices below zero on the Epex Spot market; holidays and other low-demand periods can deepen the imbalance.
Negative wholesale prices do not automatically cut household bills, and producers often keep generating because subsidies, contracts or restart costs make shutting down more expensive.
Europe's aging grid is a key bottleneck: wind and solar output from remote areas often cannot reach demand centers, despite grid investment rising 47% in five years to about 70 billion euros annually.
The imbalance is already proving costly elsewhere—Britain spent £1.47 billion last year curbing wind farms and paying gas plants to switch on—highlighting the wider challenge of integrating fast-growing renewables.
