LONDON, Sept 13 (Reuters) - Prompt British gas prices rose on Tuesday morning as imports from Norway through the Langeled pipeline fell.

Gas for day-ahead delivery rose 2.10 pence or 10 percent to 22.70 pence/therm at 1048 GMT.

Imports from Norway through the Langeled pipeline were around 5 million cubic metre (mcm), down from levels near 30 mcm the previous day, National Grid (LSE: NG.L - news) data showed.

Langeled is Britain's main subsea gas import route with a maximum capacity around 70 mcm/day.

Domestic gas production was also curbed due to planned maintenance at the Theddlethorpe terminal, scheduled to end on Sept. 16.

Flows from Theddlethorpe were below 1 mcm, the National Grid data showed.

Gas prices further out on the curve also edged higher.

The Winter 16 contract rose 0.50 pence to 38.15 p/therm, while the Q1 2017 contract was up 0.30 p at 40.30 p/therm.

In the Netherlands, the day-ahead gas price at the TTF hub was up 0.33 euro at 11.03 euros per megawatt-hour.
