极地涡旋推高美国全国范围天然气现货价格

    中国石化新闻网讯 据天然气新闻2021年2月6日纽约报道，2月5日，美国各地2月6日至8日的天然气现货价格出现飙升，据预测，一个重大的寒冷天气事件将导致美国天然气供暖需求飙升，并导致天然气产量冻结。

    美国大陆中部地区的气价飙升至2019年以来的最高水平。

    2月5日，美国天然气销售商尼科尔管道公司（NGPL）的天然气价格在交易中环比上涨了50美分，结算价为3.43美元/百万英热单位，这是自2019年3月以来的最高价格。同样，由于芝加哥的气温降到了零下，NGPL-Midcontinent Pool天然气的现金价格当日上涨了47美分，报收于3.34美元/百万英热单位。

    美国国家气象局宣布，袭击落基山脉北部的冬季风暴系统将于周六下午晚些时候抵达美国中西部地区，内布拉斯加州和伊利诺伊州将迎来降雪。芝加哥2月7日的最低气温预计为零下5度，风寒指数为零下10度。

    美国中部地区的天然气总需求预计将在今年冬季达到最高值，2月7日已达到380.6亿立方英尺/天，而美国上中西北部地区的天然气供暖需求预计将攀升至278.4亿立方英尺/天，在两天的时间内增长32%。随着美国各地气温的下降，该地区满足不断上升的需求的供应可能会放缓，这可能为美国大陆中部天然气价格的上行带来更多风险。

    2月4日，芝加哥市-关口3月天然气合约已经上涨20美分，至2.97美元/百万英热单位，而夏季天然气合约同期平均上涨10美分，至2.78美元/百万英热单位。

    Polar vortex spikes US spot gas prices across the country

    Cash prices for Feb. 6-8 flows of natural gas surged across the US on Feb. 5 as a major cold weather event is forecast to spike heating demand for gas and cause production freeze-offs.

    Midcontinent prices jump to highest levels since 2019

    Natural Gas Pipeline-Nicor was trading 50 cents higher on the day to settle to $3.43/MMBtu Feb. 5, its highest price since March 2019. Likewise, the cash price for NGPL-Midcontinent Pool jumped 47 cents on the day to settle to $3.34/MMBtu as temperatures in Chicago reach negative lows.

    The National Weather Service announced that the winter storm system hitting the Northern Rockies will reach the Midwest later Saturday afternoon, bringing snowfall from Nebraska to Illinois. Chicago temperatures Feb. 7 are forecast to reach a low of minus 5 degrees, with a wind chill of minus 10.

    Total Midcontinent demand is projected to reach its highest values this winter season at 38.06 Bcf/d Feb. 7, while heating demand in the Upper Midwest is expected to climb to 27.84 Bcf/d Sunday, a 32% increase over a two-day period. Supply into the region to meet this rising demand may falter as temperatures drop across the US, which could provide more upside risk for Midcontinent prices moving forward.

    The Chicago city-gates march contract has already spiked 20 cents on the day to $2.97/MMBtu Feb. 4, while the summer strip average climbed 10 cents over the same period to reach $2.78/MMBtu.
