British prompt gas prices dropped below 70 pence a therm for the first time since February on Thursday morning as a mild weather outlook pulled down demand while supplies were healthy.
Gas prices for delivery within the day were trading at 67.75 pence a therm at 0900 BST (0800 GMT), almost five pence lower than the previous morning, and prices for next day delivery were down 3 pence to 68.75 pence a therm.
These were the lowest levels since the end of February, when a late winter cold period began to push prices as high as 150 pence a therm.
The lower gas prices also fed into the power market, where prices for baseload (24 hours) delivery the next day fell by 4 pounds ($6.13) per megawatt-hour (MWh) between Wednesday and Thursday morning to 52.10 pounds per MWh.
