冬季風(fēng)暴埃利奧特(Elliott)在美國和加拿大造成了嚴(yán)重破壞，造成數(shù)十人死亡，數(shù)百萬家庭斷電

由于冬季風(fēng)暴埃利奧特席卷北美，美國最大的天然氣生產(chǎn)盆地阿巴拉契亞盆地的天然氣產(chǎn)量出現(xiàn)了創(chuàng)紀(jì)錄的下降

冬季風(fēng)暴讓油井和設(shè)備運(yùn)行陷于停滯，俄亥俄州的天然氣產(chǎn)量下降了50%以上，而賓夕法尼亞州的天然氣產(chǎn)量下降了20%以上

據(jù)油價(jià)網(wǎng)12月28日?qǐng)?bào)道，美國最大的天然氣生產(chǎn)盆地阿巴拉契亞地區(qū)的天然氣產(chǎn)量下降了創(chuàng)紀(jì)錄的數(shù)量，原因是冬季風(fēng)暴埃利奧特席卷了賓夕法尼亞州和俄亥俄州，凍結(jié)了油井和一些設(shè)備，并導(dǎo)致管道基礎(chǔ)設(shè)施出現(xiàn)機(jī)械問題。

根據(jù)BloombergNEF基于管道流量的估計(jì)，與平常水平相比，阿巴拉契亞盆地的天然氣供應(yīng)下降了27%，即90億立方英尺。彭博社指出，這是自2013年有記錄以來跌幅最大的一次。

在賓夕法尼亞州，由于油井凍結(jié)，天然氣產(chǎn)量下降了20%以上。據(jù)彭博社估計(jì)，俄亥俄州的天然氣產(chǎn)出減少了一半以上。

冬季風(fēng)暴埃利奧特切斷了數(shù)百萬家庭的電力供應(yīng)，并打亂了數(shù)百萬人的圣誕節(jié)旅行計(jì)劃，數(shù)千架航班被取消。就在圣誕假期周末之前，近2.5億美國和加拿大居民受到這樣或那樣的風(fēng)暴影響，數(shù)十人死亡。

截至12月27日周二，美國的天然氣產(chǎn)量仍明顯低于過去幾周的水平。天然氣情報(bào)機(jī)構(gòu)引用的早期生產(chǎn)數(shù)據(jù)顯示，美國天然氣日產(chǎn)量仍在800億～860億立方英尺左右，遠(yuǎn)低于過去幾周和幾個(gè)月的1000億立方英尺的日產(chǎn)量。

本周，幾條天然氣管道繼續(xù)報(bào)告問題，這進(jìn)一步限制了天然氣流向系統(tǒng)的能力。

阿巴拉契亞天然氣產(chǎn)量的暴跌加劇了電網(wǎng)的問題，因?yàn)橥ㄟ^管道輸送到燃?xì)獍l(fā)電機(jī)組的天然氣數(shù)量減少了。

與此同時(shí)，冬季風(fēng)暴埃利奧特期間電力需求激增，導(dǎo)致美國一些地區(qū)的電力系統(tǒng)緊張。田納西河谷管理局和杜克能源公司在圣誕節(jié)前夕在田納西河谷和卡羅來納州實(shí)施了輪流停電，以保持電網(wǎng)穩(wěn)定。

U.S. Natural Gas Production Plunges As Winter Storm Wreaks Havoc

·     Winter Storm Elliott has wreaked havoc across the U.S. and Canada, leaving dozens of people dead and cutting power to millions of households.

·     The Appalachia basin, the top natural gas-producing basin in the U.S., saw production drop by a record amount as the storm swept through.

·     Natural gas output fell by more than 50% in Ohio and by more than 20% in Pennsylvania as the storm froze wells and equipment.

Natural gas output in the Appalachia region, the top gas-producing basin in the U.S., dropped by a record amount as Winter Storm Elliott swept through Pennsylvania and Ohio, freezing wells and some equipment and creating mechanical issues at pipeline infrastructure.

The Appalachia basin saw natural gas supply drop by 27%, or by 9 billion cubic feet, compared to the typical levels, according to estimates by BloombergNEF based on pipeline flows. The decline was the steepest on record in data since 2013, Bloomberg notes.  

In Pennsylvania, natural gas production fell by more than 20%, due to well freeze-offs. In Ohio, output more than halved, according to Bloomberg’s estimates.

Winter Storm Elliott cut off the power supply to millions of households and disrupted Christmas travel plans for millions more as thousands of flights were canceled. Just ahead of the Christmas holiday weekend, almost 250 million U.S. and Canadian residents were affected by the storm in one way or another, and dozens of people have died.

As of Tuesday, December 27, U.S. natural gas production was still significantly below the levels of the past weeks. Early production data, cited by Natural Gas Intelligence, showed that American natural gas output was still around 80-86 Bcf/d, well below the 100 Bcf/d production of the past weeks and months. 

Several gas pipelines continued to report issues this week, which has further constrained the ability of gas flows to the systems.  

The plunge in the Appalachia natural gas production exacerbated issues at the grids as lower volumes of gas were sent via pipelines to gas-fired power generation units.

This happened just as power demand surged during the storm, straining electricity systems in some areas in the U.S. The Tennessee Valley Authority and Duke Energy implemented rolling blackouts in the Tennessee Valley and the Carolinas ahead of Christmas Eve to maintain grid stability.
