- Overall, the UK gas system was under-supplied by 10 mcm on Thursday, with demand forecast at around 263 mcm, and supply at almost 253 mcm, National Grid data showed.
British wholesale gas prices fell on Thursday, dragged by renewed coronavirus restrictions across the region and expectations of lower demand during the Christmas holidays.
The day-ahead contract was down 1.25 pence at 44.00 p/therm by 0953 GMT.
Gas for immediate delivery was down 0.45 pence at 44.75 p/therm.

Some upside risk stemmed from lower send-out of liquefied natural gas (LNG) and from Norwegian gas flows to Britain, which were down by 11 million cubic metres (mcm) day-on-day at 104 mcm/day, Refinitiv said.
High demand for LNG in Asia drew away a significant share of LNG from Europe, analysts at Marex Spectron said, creating a tightness in European markets.
