Closing prices 30.05.2025

The British spot gas price edged 0.6% lower at 3.0 p/kWh on Wednesday, amid continued improvement in Norwegian pipeline flows. However, further declines were limited by ongoing maintenance and unplanned outages at the Visund and Troll gas fields. The Winter 2025 delivery contract fell by 0.5% to around 3.3 p/kWh, pressured by the lack of any breakthrough toward a peace deal in Ukraine.
Milder weather put pressure on the British spot gas price on Thursday. As a result, the NBP spot price slumped by over 6% to 2.8 p/kWh. On the forward curve, the Winter 2025 delivery contract dipped by 3.2% to around 3.2 p/kWh, influenced by Russian proposals for direct negotiations with Ukraine on June 2 and improved supply conditions across Europe.
At time of writing, European gas storage levels are 48% full, with the UK 26% full. European gas storage levels are trending just below the 5-year average throughout 2024.
