Closing prices 25.07.2025

The NBP spot price dropped by around 1% to 2.7 p/kWh on Tuesday, pressured by ample supply and stable demand, with bearish weather forecasts adding to the downside.
British gas prices dropped sharply on Thursday, driven by technical selling in a subdued market. The NBP spot price slumped by nearly 5% to 2.6 p/kWh as extended maintenance at Norway’s Troll field reduced availability by around 15 mcm/day. Further along the curve, the Winter 2025 delivery contract held steady at 3.1 p/kWh, amid ongoing injections into European gas storage that are on track to meet EU targets.
At time of writing, European gas storage levels are 67% full, with the UK 32% full. European gas storage levels are trending just below the 5-year average throughout 2024. Over the past week gas has accounted for 30% of the UK generation mix with wind accounting for 17%, solar 10% and nuclear accounting for 17%.
