Europe’s solar problem is no longer just about building more generation. It is about finding enough flexible demand. Pexapark’s latest analysis shows how severe solar cannibalization has become in Europe: France’s solar capture factor fell ~75% YoY in April 2026, from ~0.42 to ~0.10. Almost half of its solar generation occurred during negative-price hours. Germany recorded 123 negative-price hours in April, up 65% YoY, with 46.8% of solar output produced during negative-price periods. Spain is no longer facing this only in summer. In February 2026, its solar capture factor collapsed to ~0.18 from ~0.71 a year earlier, while negative-price hours jumped from zero to 148. The message is clear: solar deployment is now running ahead of system flexibility. Batteries, grid expansion and demand response are essential. But Europe should also take interruptible loads seriously — including Bitcoin mining and other compute loads that can turn on when power is abundant and shut down when the grid is tight. Properly designed, flexible loads can become buyers of last resort for surplus renewable power, reduce curtailment, improve solar project revenues, and make further investment in generation and grid infrastructure more profitable and bankable.
