Strong supply expectations also weighed on the forward curve. The Summer 2026 delivery contract edged 0.3% lower at 2.6 p/kWh, as EU LNG imports are set to rise 33% this winter, more than offsetting a projected 4 bcm drop in pipeline flows. European spot electricity prices extended losses on Wednesday.
The British spot gas price edged 0.4% higher at 2.8 p/kWh on Thursday, following overnight Russian drone and missile strikes on DTEK and Naftogaz facilities in Ukraine’s Poltava region, prompting Ukraine to consider boosting winter gas imports by 25%. Concerns over supply disruptions also lifted the forward market, with the Summer 2026 delivery contract increasing by 0.8% to 2.6 p/kWh. However, ample LNG availability capped gains.
At time of writing, European gas storage levels are 83% full, with the UK 53% full. European gas storage levels are trending around the 5-year average. Over the past week gas has accounted for 51% of the UK generation mix with wind accounting for 18%, solar 2% and nuclear accounting for 12%.
