Dec 10 (Reuters) - U.S. natural gas futures climbed almost 3% to a one-week high on Friday on forecasts for heating demand to rise in a couple of weeks with a seasonal cooling of the weather. Traders noted that price rise occurred even though the weather was expected to remain milder than normal through late December. Front-month gas futures rose 11.1 cents, or 2.9%, to settle at $3.925 per million British thermal units (mmBtu), their highest close since Dec. 3. The contract, however, was still down about 5% for the week after it plunged more than 11% on Monday, its biggest daily decline since January 2019. Last week, the contract dropped more than 24% in its biggest weekly decline since February 2014. In recent months, global gas prices hit record highs as utilities around the world scrambled for liquefied natural gas (LNG) cargoes from the United States and elsewhere to replenish low stockpiles in Europe and meet surging demand in Asia, where energy shortfalls have caused power blackouts in China. U.S. futures jumped to a 12-year high in early October but have since pulled back because the United States has plenty of gas in storage and ample production for winter. Overseas prices were currently trading about nine times higher than U.S. futures. Analysts have said European inventories were about 20% below normal for this time of year, compared with just 3% below normal in the United States. Looking ahead, many analysts said mild weather expected in coming weeks will allow U.S. utilities to leave enough gas in storage to cause stockpiles to reach above-normal levels by mid-December. That would be the first time storage would be at above-normal levels since April. Data provider Refinitiv said output in the U.S. Lower 48 states has averaged 96.3 billion cubic feet per day (bcfd) so far in December, down from a monthly record of 96.5 bcfd in November. Refinitiv projected average U.S. gas demand, including exports, would drop from 116.9 bcfd this week to 110.5 bcfd next week with an unusual warming of the weather before rocketing to 121.8 bcfd in two weeks as temperatures turn seasonally colder. The amount of gas flowing to U.S. LNG export plants has averaged 11.8 bcfd so far in December now that the sixth train at Cheniere Energy Inc"s (LNG.A) Sabine Pass plant in Louisiana is producing LNG. That compares to 11.4 bcfd in November and a monthly record of 11.5 bcfd in April. With gas prices around $34 per mmBtu in Europe and $35 in Asia , compared with about $4 in the United States, traders said buyers around the world would keep purchasing all the LNG the United States can produce. But no matter how high global gas prices rise, the United States only has the capacity to turn about 11.1 bcfd of gas into LNG. The rest of the gas flowing to the export plants is used to fuel equipment that produces the LNG. Global markets will have to wait until later this year to get more when Venture Global LNG"s Calcasieu Pass in Louisiana starts producing LNG in test mode. read more Week ended Dec 10 (Forecast) Week ended Dec 3 (Actual) Year ago Dec 10 Five-year average Dec 10 U.S. weekly natgas storage change (bcf): -72 -59 -118 -114 U.S. total natgas in storage (bcf): 3,433 3,505 3,743 3,481 U.S. total storage versus 5-year average -1.4% -2.5% Global Gas Benchmark Futures ($ per mmBtu) Current Day Prior Day This Month Last Year Prior Year Average 2020 Five Year Average (2016-2020) Henry Hub 3.88 3.82 2.58 2.13 2.66 Title Transfer Facility (TTF) 33.82 34.12 5.82 3.24 5.19 Japan Korea Marker (JKM) 35.19 35.15 9.46 4.22 6.49 Refinitiv Heating (HDD), Cooling (CDD) and Total (TDD) Degree Days Two-Week Total Forecast Current Day Prior Day Prior Year 10-Year Norm 30-Year Norm U.S. GFS HDDs 346 337 381 395 403 U.S. GFS CDDs 9 10 2 5 4 U.S. GFS TDDs 355 347 383 400 407 Refinitiv U.S. Weekly GFS Supply and Demand Forecasts Prior Week Current Week Next Week This Week Last Year Five-Year Average For Month U.S. Supply (bcfd) U.S. Lower 48 Dry Production 97.2 96.5 96.4 91.2 84.7 U.S. Imports from Canada 8.8 8.7 8.6 9.2 8.9 U.S. LNG Imports 0.0 0.0 0.0 0.2 0.3 Total U.S. Supply 105.9 105.2 105.1 100.6 93.9 U.S. Demand (bcfd) U.S. Exports to Canada 3.4 3.6 3.6 2.8 3.0 U.S. Exports to Mexico 5.7 5.7 5.6 5.7 4.6 U.S. LNG Exports 11.8 12.1 11.7 11.4 5.0 U.S. Commercial 13.1 13.8 12.9 14.1 15.0 U.S. Residential 20.5 21.9 21.2 22.7 25.4 U.S. Power Plant 26.6 28.6 25.0 28.2 25.8 U.S. Industrial 23.6 23.8 23.2 24.5 24.6 U.S. Plant Fuel 4.8 4.8 4.8 4.8 4.8 U.S. Pipe Distribution 2.4 2.5 2.4 2.5 2.4 U.S. Vehicle Fuel 0.1 0.1 0.1 0.1 0.1 Total U.S. Consumption 91.2 95.6 89.6 96.9 98.1 Total U.S. Demand 112.1 116.9 110.5 116.8 110.7 U.S. weekly power generation percent by fuel - EIA Week ended Dec 10 Week ended Dec 3 Week ended Nov 26 Week ended Nov 19 Week ended Nov 12 Wind 11 11 13 14 14 Solar 2 2 2 2 2 Hydro 7 6 6 6 6 Other 2 2 2 2 2 Petroleum 1 1 1 1 1 Natural Gas 37 37 34 35 35 Coal 19 19 20 19 19 Nuclear 22 22 22 21 21 SNL U.S. Natural Gas Next-Day Prices ($ per mmBtu) Hub Current Day Prior Day Henry Hub 3.67 3.79 Transco Z6 New York 3.21 5.72 PG&E Citygate 5.25 5.22 Dominion South 2.92 3.28 Chicago Citygate 3.43 3.54 Algonquin Citygate 3.67 8.55 SoCal Citygate 7.37 7.19 Waha Hub 3.28 3.30 AECO 3.02 3.09 SNL U.S. Power Next-Day Prices ($ per megawatt-hour) Hub Current Day Prior Day New England 56.50 88.25 PJM West 24.25 31.00 Ercot North 31.50 33.00 Mid C 38.00 49.00 Palo Verde 38.00 32.00 SP-15 55.25 50.75 Reporting by Scott DiSavino Editing by Chizu Nomiyama and Paul Simao
