* Langeled supply rises by one third as Europipe work starts
* Curve falls as market heads for correction
* Strong wind, weak gas weigh on power
LONDON, Aug 25 (Reuters) - UK prompt gas prices fell on Thursday as maintenance on a Norwegian pipeline to Germany made more gas available to UK customers, cancelling out the impact of higher demand and weak supply from liquefied natural gas (LNG) terminals.
Supply from Norway via the Langeled pipeline rose by one third on Thursday morning to 60 million cubic metres per day (mcm/day), National Grid data showed.
"I believe the maintenance is having an impact as the UK is seeing around 20 mcm more gas currently compared to yesterday from Norway," one UK gas market analyst at a utility said.
The rise in Norwegian imports left the market oversupplied, despite a drop in flows from the Isle of Grain LNG terminal and a rise in demand to near seasonal norms.
The 45.5 cubic-metre per day Europipe 1 pipeline started a 12-day maintenance outage on Thursday, shifting more Norwegian exports to Britain.
Supply from the Isle of Grain terminal fell to around 5 mcm/day on Thursday morning, while demand rose above 220 mcm/day, just three percent below seasonal norms, National Grid data showed. Continued...
