UK GAS-Prices rise on high on lower wind, lingering supply concerns

Aug 18 (Reuters) - British wholesale gas for day-ahead
delivery rose to its highest level since Feb. 2018 on Wednesday
morning as a drop in wind output increased gas demand for power
generation.

* Gas for next-day delivery rose by 3.80 pence
to
118.00 pence per therm by 0906 GMT.

* The October contract was 2.00 pence higher at
120.50 p/therm.

* Refinitiv revised its forecast for gas-for-power demand
for
Thursday 14 mcm/day higher amid weaker wind speeds.

* Peak wind power generation will drop from 7.1 gigawatts
(GW)on
Wednesday to 3.4 GW on Thursday, out of total metered capacity
of nearly 20 GW, according to Elexon data.

* "We expect [the day-ahead] price to edge up today given a
still
bullish underlying winter risk on European gas markets,"
Refinitiv gas analyst Katarzyna Piaskowska said.

* The UK gas system opened balanced on Wednesday morning
following
several days of oversupply, National Grid data showed.

* But the market could tighten as maintenance curbs
Norwegian gas
imports.

* Russian supply to north-west Europe remains a concern, as
well
as low gas inventories on the continent before the winter,
Piaskowska said.

* Market players continue to closely monitor Russian gas
flows
through the Yamal-Europe pipeline, a trader said.

* Flows at the key entry point at Mallnow last stood at 385
gigawatt hours per day, sightly down from Tuesday, Refinitiv
data showed.

* Volumes have been curbed since a fire at a condensate
preparation plant in northern Russia.

* The front-month gas price at the Dutch TTF
hub was
1.10 euros higher at 47.60 euros per megawatt hour.

* The benchmark Dec-21 EU carbon contract was 0.52
euro
firmer at 57.71 euros a tonne.

* The benchmark Dec-21 British carbon contract was
slow
to trade. It closed at 49.39 pounds per tonne on Tuesday.
