May 21, 2025UK Energy Market Summary to Friday 16th May 2025

Closing prices 16.05.2025

Despite the UK securing an additional LNG cargo for May 25, bringing the monthly total to four, the British spot gas price increased by 0.6% to 2.7 p/kWh on Wednesday, supported by an unplanned outage at Norway’s Kårstø gas processing plant.
The British spot gas price increased by 2.5% to 2.8 p/kWh on Thursday amid reduced Norwegian supply nominations. Lingering uncertainty over Ukraine-Russia peace efforts lent support to prices further along the curve. As a result, the Winter 2025 delivery contract edged 0.4% higher at 3.2 p/kWh, intensified by the absence of both the Russian and U.S. presidents, which kept market sentiment cautious.
At time of writing, European gas storage levels are 44% full, with the UK 33% full. European gas storage levels are trending just below the 5-year average throughout 2024. Over the past week gas has accounted for 20% of the UK generation mix with wind accounting for 26%, solar 14% and nuclear accounting for 18%. Below summarises curve prices as at close of business on Friday.
