* The system was oversupplied by 8 million cubic metres (mcm), with demand forecast at 236.5 mcm and supply seen at 244.8 mcm.

* Demand was far higher than seasonal norms of around 185 mcm due to below average temperatures, which are expected to climb later in the week.

* Norwegian gas flows to Britain rose 4 mcm to 73 mcm, helped by higher flows along the Langeled pipeline.

* Peak wind generation was expected to remain high at 8.8 gigawatts (GW) but that will fall to 6.0 GW on Thursday.

* High winds tend to reduce demand for gas used in power generation; gas for power demand for Wednesday is 37 mcm lower than previously expected at 27 mcm although that will climb to 39 mcm on Thursday.

* Send-out from liquefied natural gas (LNG) terminals is expected to be weaker by 6 mcm due to lower activity at the Dragon and Isle of Grain terminals.

* However, two tankers are due to discharge this week with another two next week, keeping send-out rates at still above that of recent years.

* The June gas contract was up 0.3 pence to 32.20 p/therm
