UK gas falls as Norway imports regain

* Langeled flows rise near 70 mcm/d

* Curve slides with oil as Asia growth forecast cut

* Low wind supports power prices

LONDON, Oct 8 (Reuters) - British prompt gas prices eased onMonday as imports from Norway via the Langeled pipeline regainedfull strength following processing problems last week, whilemilder weather forecasts for October also helped keep a lid ongains.

Gas for within-day delivery slipped to 62.20 pence, down0.05 pence on Friday's closing level at 0830 GMT and day-aheadgas

traded down at 62.30 pence.

"The market is down this morning. Norwegian producers haveincreased flows today after maintenance and the weather has comein slightly warmer for October," a UK gas trader at a bank said.

Langeled imports rose to nearly 70 million cubic metres perday (mcm/d) on Monday, after a hiccup last week to restartNorway's main plant processing gas for export, Kollsnes, wasresolved.

Problems to fully restart the Kollsnes plant last weekspooked some traders and the fact that Monday's within-day gasprice was not significantly lower showed that some participantsmaintained long positions due to scepticism about the facility'sreliability, one market analyst said.

The UK gas system was well supplied on Monday thanks to thesurge in Norwegian imports and steady flows from theNetherlands. The UK gas premium over Belgian gas prices alsoincentivised some gas flows into Britain via the Interconnectorpipeline, National Grid data showed.

Losses on the prompt also weighed on the front months, withNovember shedding 0.65 pence to 63.45 pence and December tradingat 65.35 pence, down 0.35 pence on the previous session.

Summer 2013 gas

slid in line with a weak oilprice, which reacted to the World Bank cutting its economicgrowth outlook for East Asia and the Pacific, home to two of theworld's largest oil consuming nations.

The front-season gas price fell 0.25 pence to 60.75 pence,while winter 2013/14 gas traded down 0.45 pence at 69.60 pence.

In Britain's over-the-counter power market short-term pricesrose on the back of a downward revision in wind power productionforecasts.

"Low wind predominantly is leaving the system reasonablytight," said on UK power trader.

Baseload day-ahead electricity traded at 45.40 pounds permegwatt-hour, up nearly 2 pounds on Friday's spot trading level.

Wind power output was expected to drop below 600 MW onTuesday and Monday's levels turned out around 300 MW less thanforecast, National Grid data showed.
