可再生能源产出激增席卷欧洲电网 2025年负电价频率创历史新高

Group 1 - The core issue is the increasing frequency of negative electricity prices in Europe due to a surge in renewable energy production, which is outpacing demand and grid capacity [1][4][6] - Germany recorded 573 hours of negative electricity prices in 2025, a 25% increase from the previous year, while Spain has seen its frequency of negative prices double since first experiencing them in 2024 [1][4] - The expansion of renewable energy capacity is expected to continue leading to negative pricing patterns through 2026, as the growth of grid infrastructure and energy storage lags behind new generation facilities [4][6][8] Group 2 - The increase in negative pricing is reshaping the European electricity market, squeezing revenues for renewable energy developers while creating new opportunities for trading firms to profit from price volatility [4][6] - The reliance on fossil fuels remains significant for backup support during periods of renewable energy output fluctuations, leading to potential price spikes when demand exceeds supply [6][8] - Efforts to develop more renewable energy face challenges from slow recovery in electricity demand and the increasing role of natural gas and coal in meeting additional load in certain markets [6]
