Europe curtails solar power as gas supply tightens

Europe is increasingly curtailing solar power generation as grid infrastructure struggles to handle the surge in renewable output, wasting vast amounts of electricity at a time when natural gas markets are tightening. The phenomenon, known as curtailment, occurs when grids cannot absorb all the electricity produced, forcing operators to switch off solar farms even during peak sunlight hours. This comes as gas storage levels decline and supply concerns mount, pushing benchmark European gas prices higher.

For energy traders, the simultaneous waste of solar power and rising gas demand highlights a structural imbalance in Europe's energy transition. When solar generation is curtailed, gas-fired power plants must run more to meet demand, increasing gas consumption and supporting prices. This dynamic can amplify price volatility, especially during periods of low wind or when gas storage injections are needed ahead of winter. NowPrice live fuel prices and charts show how the market is reacting to these cross-currents, with gas futures sensitive to any shift in renewable output.

Looking ahead, traders should watch for further grid congestion as more solar capacity comes online, particularly in Germany and Spain. The pace of battery storage deployment and grid upgrades will be critical in determining how much solar waste persists. Meanwhile, any disruption to gas supply — from LNG cargo delays or geopolitical tensions — could exacerbate the price impact. The interplay between renewable curtailment and gas demand will remain a key theme for European energy markets through 2026.
