LONDON, April 2 (Reuters) - Dutch and British gas prices moved lower on Wednesday morning as warmer weather forecasts curbed demand, while the market is also closely monitoring Trump's "Liberation Day" tariff plan.
The Dutch front-month contract TRNLTTFMc1 was down by 0.54 euro to 42.13 euros per megawatt hour (MWh) or $13.34/mmBtu, by 0811 GMT, LSEG data showed.
The Dutch day-ahead contract TRNLTTFD1 was down 0.72 euro at 41.95 euros/MWh.
The British day-ahead contract TRGBNBBD1 was down 0.85 pence at 101.75p/therm.
U.S. President Donald Trump was poised to impose sweeping tariffs on global trading partners on Wednesday, threatening cost increases and likely drawing retaliation.
"Today could be volatile and fundamentals disregarded with Liberation day concerns fuelling concerns on global markets and Trumps decisions could have a detrimental impact on global trade," said LSEG analyst Wayne Bryan.
Meanwhile in Northwest Europe, demand for heating is forecast lower across the prompt with an upwards revision to temperatures. Demand for the day ahead is down by 441 gigawatt hour per day (GWh/d), while demand for weekend and working days next week are seen down by 45GWh/d and 80GWh/d respectively, LSEG data showed.
Europe has started the gas refilling season after a cold and lengthy winter with gas storage sites currently almost two-thirds empty.
"This is the first year that storage must be replenished without pipeline gas flowing through Ukraine... The risk associated with refilling is at its highest level ever," consultancy Global Risk Management said in a research note.
Norway's first major planned maintenance this summer begins today at the Nyhamna gas processing plant and is due to run until 7 April.
"Even though Gassco said that summer’s gas maintenance schedule is set to be lighter than it was in the past two years, this drop in Norwegian flows will not improve the EU storage situation," analysts at Engie's EnergyScan said in a morning note.
In the European carbon market, the benchmark contract CFI2Zc1 was up 0.01 euro at 67.99 euros a metric ton.
