LONDON, July 28 (Reuters) - Prompt British wholesale gas
prices rose on Tuesday morning as flows through the Langeled
pipeline from Norway were at zero and as wind power output
increased.
* The within-day contract was up 0.35 pence at
12.35
pence per therm by 0810 GMT.
* The day-ahead contract was up 1.15 pence at
12.75
p/therm.
* Flows from Norway through the Langeled pipeline are at
zero.
There are no notifications from Gassco to explain the drop.
* Flows are nominated at 6.7 million cubic metres (mcm) and
should
start flowing later, said Wayne Bryan, analyst at Refinitiv.
* "Renewable output is high today and we do not need the gas
at
present," he said.
* Wind speeds are high and currently providing 8 gigawatts
(GW) or
39% of the power mix, he added.
* Peak wind generation is forecast at 12.5 GW on Tuesday and
nearly 11 GW on Wednesday, Elexon data shows, out of a total
metered capacity of 18 GW.
* High wind output typiclly reduces demand from
gas-for-power
plants.
* Gas for power demand was 15.6 mcm/d, down 20 mcm from
yesterday.
* The system was nearly balanced with demand forecast at 144
mcm
and flows at 141 mcm/day, National Grid data shows.
* The September contract was down 0.23 pence at
14.40
p/therm.
* The day-ahead gas price at the Dutch TTF hub
was up
0.12 at 4.50 euros per megawatt hour.
* The benchmark Dec-20 EU carbon contract was 0.25
euro
higher at 25.26 euros a tonne.
