UK GAS-Prices fall on higher Norwegian flows, strong wind power output

Oct 2 (Reuters) - British wholesale gas prices fell on Wednesday as an increase in imports from Norway and strong wind power generation left the market oversupplied.

* Day-ahead gas fell by 0.75 pence to 26.25 pence/therm by 0829 GMT

* The November gas contract was down by 0.40 pence to 43.30 pence per therm.

* Higher gas imports from Norway and strong output from wind turbines were behind the price rise, said a British gas trader.

* The gas system was oversupplied, with demand forecast at 192.6 million cubic metres (mcm) and supply at 206.1 mcm/day, National Grid data showed.

* Norwegian gas flows rose to 53 mcm/day on Wednesday from 39 mcm/day the previous day. Gas flows via the Langeled pipeline were nearly double the previous day, reaching 30 mcm/day.

* Wind power generation is expected to reach 7.8 gigawatts (GW) on Wednesday out of 12.1 GW capacity, according to Elexon data. It is forecast at 10.2 GW for Thursday.

* High power output from wind turbines typically reduces gas-for-power demand.

* Liquefied natural gas imports (LNG) were also contributing to the overall price decline in Britain, added the trader.

* Britain received an LNG cargo on Tuesday and is expecting eight more vessels by the end of October.

* Average daily temperatures are forecast at 8.8 degrees Celsius for Wednesday and are expected to fall to 8.5C the next day, Refinitiv Eikon data showed.

* Day-ahead gas at the Dutch TTF hub rose by 0.15 euro to 10.10 euros per megawatt hour (MWh)

* The Dutch month-ahead gas contract, a benchmark for LNG prices as well as European gas, was down by 0.10 euro at 16.30 euros/MWh.

* The benchmark Dec-19 EU carbon contract fell by 0.26 euro to 24.78 euros a tonne. (Reporting by Lefteris Karagiannopoulos in Oslo; editing by Nina Chestney)
