UK GAS-Prices rise as imports from Norway drop

* Imports through Langeled drop below 15 mcm

* Oil prices up more than 2 pct

LONDON, May 5 (Reuters) - British prompt gas prices rose on Thursday morning as imports from Norway dropped, while gas prices further along the curve were buoyed by higher oil.

Gas for within-day delivery fetched 29.50 pence per therm at 0813 GMT, up 1.2 pence from the last settlement.

Gas for day-ahead delivery rose 1.40 pence, or 5 percent, to 29.60 pence per therm.

Norwegian imports through Langeled, Britain's main gas import pipeline, were below 15 million cubic metres (mcm), down from levels of around 40 mcm the previous day, National Grid (LSE: NG.L - news) data showed.

Imports from the Netherlands through the BBL pipeline have been at zero since the beginning of this month.

A fall in expected electricity output from the country's wind farms also helped to boost demand for gas from gas-fired power plants.

Peak wind output was forecast to reach 4.6 gigawatts (GW) on Thursday before falling to 1.6 GW by Friday, National Grid data showed.

With (Other OTC: WWTH - news) supply flows at about 211.5 mcm and demand expected to be 212.6 mcm/day, Britain's gas system was almost balanced, National Grid data showed.

Traders said higher oil prices have helped to lift gas prices along the curve.

The June contract rose 1.35 pence to 29.25 pence per therm, while the Winter '16 contract was up 1.40 pence at 36.80 pence per therm.

Brent crude oil prices rose more than 2 percent to $45.60 a barrel as a huge wildfire in Canada disrupted oil sands production and escalating fighting threatened output in Libya.

In the Netherlands' gas market, the day-ahead price at the TTF hub gained 0.43 euro to 12.73 euros per megawatt-hour.

In Europe's carbon market, the front-year EU Allowance price rose 0.21 euro to 6.35 euros per tonne. (Reporting by Susanna Twidale; editing by Nina Chestney)
