LONDON, Oct 18 (Reuters) - British and European wholesale gas prices extended gains on Monday morning after auctions showed Russia's Gazprom booked a fraction of gas transit capacity via Poland.
* The Dutch wholesale gas price for November was 15.1 euros higher at 103.50 euros per megawatt hour (MWh) by 1043 GMT.
* The Dutch wholesale gas contract for next day delivery rose by 13.15 euros to 100.15 euros/MWh.
* In the UK market, the British wholesale gas contract for immediate delivery was up 26.25 pence to 2.28 pounds per therm.
* The day-ahead price was up 32.0 pence at 2.35 pounds per therm.
* Gazprom booked about a third of offered additional gas transit capacity via the Yamal - Europe pipeline via Poland for November and has not booked any volumes via Ukraine, auction results showed on Monday.
* Deputy Prime Minister Alexander Novak said on Saturday Russian gas consumption is running at a record high but Moscow is still ready to increase supplies to Europe should it receive such requests.
* He also said that commercial gas deliveries via Nord Stream 2 may start right after the German regulator grants its permission.
* The operator of Russia-led Nord Stream 2 gas pipeline on the bed of the Baltic Sea said on Monday the first string of the pipeline has been filled with technical gas. The pipeline is still expected to get a certification from a German regulator to start commercial sales of natural gas.
* "Mixed messages from Russia over the last few days as well as the fact nothing has been booked or flows to northwest Europe have not increased tells us that risk remains firmly on the table," Refinitiv analysts said.
* Temperatures in the UK are forecast to rise significantly above season seasonal norm on the day-ahead but fall again by the weekend, Refinitiv Eikon data showed.
* Wind power in Britain is forecast at 10 gigawatts (GW) on Monday and slightly higher at nearly 12 GW on Tuesday, Elexon data showed.
