UK GAS-Prices inch higher on Norwegian maintenance and rising LNG prices

June 8 (Reuters) - British wholesale gas prices rose on
Tuesday morning, extending the gains from the previous session,
due to heavy maintenance in Norway, although stable demand due
to warm weather still kept the UK system oversupplied.

* The day-ahead contract was up 2.55 pence at
67.00
p/therm by 0823 GMT.

* Around 60 million cubic metres (mcm) per day of Norwegian
capacity were unavailable due to maintenance on Tuesday, and
the capacity restrictions was expected to reach a season-high of
207 mcm per day, Refinitiv analysts said.

* The UK system was almost 12 million cubic metres (mcm)
over-supplied on Tuesday morning, with demand forecast at around
146 mcm/day and supply at around 158 mcm/day, National Grid data
showed.

* Tuesday's demand was still 32 mcm lower than the seasonal
norm,
according to Refinitiv.

* UK consumption forecasts remained stable as the country
faced
dry and sunny weather this week, with temperatures remaining
above normal, Refinitiv analysts said.

* Rising Asian liquefied natural gas (LNG) prices - due to
stronger oil and firm demand from China and Europe - was also
supportive for gas in European hubs.

* Peak wind generation is forecast at 3.5 gigawatts (GW)
today,
but will increase to 6 GW on Wednesday, out of total metered
capacity of almost 20 GW, Elexon data showed.

* Gas demand for power generation was expected at 31 mcm per
day
for Wednesday, down from 34 mcm per day on Tuesday, according to
Refinitiv data.

* The Dutch gas price for the next day at the TTF hub
was 0.83 euro higher at 27.50 euros per megawatt hour.

* The benchmark Dec-21 EU carbon contract was 0.75
euro
higher at 52.22 euros a tonne.

* The UK Dec-21 carbon contract rose 0.05 pounds
to
46.50 pounds per tonne.
