UK GAS-Prices ease on near balanced system

* System short 2 mcm - National Grid (LSE: NG.L - news)

* Langeled flows at around 52 mcm/day

LONDON, Feb 2 (Reuters) - British gas prices edged lower on Tuesday, with supply and demand almost matched, as mild weather curbed demand.

Gas for immediate delivery traded down 0.15 pence, or 0.5 percent, at 29.50 pence per therm as of 0835 GMT.

Britain's gas system was undersupplied by a modest 2 million cubic metres (mcm), with demand forecast at 272 mcm and supply at 270 mcm, according to National Grid data.

Demand was below seasonal norms of 287 mcm with temperatures forecast to stay milder than usual for this time of year.

The Met Office forecasts temperatures of around six to nine degrees Celsius on Tuesday.

"Demand still suggests a bearish scenario, driven by a positive climate spread and slightly warmer than average weather conditions for central and western Europe," brokerage Marex Spectron said in a note published on Tuesday.

Imports from Norway's Langeled pipeline were around 52 mcm, down slightly from around 55 mcm the previous day.

Further along the curve, gas for March was trading down 0.25 pence or 0.8 percent at 29.35 pence per therm.

In the Netherlands, the day-ahead gas price at the TTF hub fell 0.32 euro to 12.50 euros per megawatt-hour, while in the European carbon market, front-year allowances were up 0.02 euro at 5.73 euros a tonne. (Reporting by Sarah McFarlane; Editing by Mark Potter)
