Closing prices 13.03.2026

British forward wholesale gas prices climbed on Wednesday after recent attacks on vessels in the Strait of Hormuz, a key route for around 20% of global LNG supply. As a result, the Q3 2026 contract surged by 5.3% to 4.2 p/kWh, while the NBP spot price increased by 5.6% to 4.2 p/kWh.
British forward wholesale gas prices continued to rise on Thursday, amid renewed Iran threats to escalate the war. Hence, the Q3 2026 contract closed at 4.1 p/kWh, or a 3% increase on the day. Similarly, the NBP spot price rose by 2.2% to 4.3 p/kWh, as weaker renewables generation boosted gas-for-power demand.

Over the past week gas has accounted for 21.4% of the UK generation mix with wind accounting for 45.6%, solar 5.5% and nuclear accounting for 9.5%.
