冬季風暴埃利奧特(Elliott)在美國和加拿大造成了嚴重破壞，造成數十人死亡，數百萬家庭斷電

由于冬季風暴埃利奧特席卷北美，美國最大的天然氣生產盆地阿巴拉契亞盆地的天然氣產量出現了創紀錄的下降

冬季風暴讓油井和設備運行陷于停滯，俄亥俄州的天然氣產量下降了50%以上，而賓夕法尼亞州的天然氣產量下降了20%以上

據油價網12月28日報道，美國最大的天然氣生產盆地阿巴拉契亞地區的天然氣產量下降了創紀錄的數量，原因是冬季風暴埃利奧特席卷了賓夕法尼亞州和俄亥俄州，凍結了油井和一些設備，并導致管道基礎設施出現機械問題。

根據BloombergNEF基于管道流量的估計，與平常水平相比，阿巴拉契亞盆地的天然氣供應下降了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，天然氣產量下降了20%以上。據彭博社估計，俄亥俄州的天然氣產出減少了一半以上。

冬季風暴埃利奧特切斷了數百萬家庭的電力供應，并打亂了數百萬人的圣誕節旅行計劃，數千架航班被取消。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暴影響，數十人死亡。

截至12月27日周二，美國的天然氣產量仍明顯低于過去幾周的水平。天然氣情報機構引用的早期生產數據顯示，美國天然氣日產量仍在800億～860億立方英尺左右，遠低于過去幾周和幾個月的1000億立方英尺的日產量。

本周，幾條天然氣管道繼續報告問題，這進一步限制了天然氣流向系統的能力。

阿巴拉契亞天然氣產量的暴跌加劇了電網的問題，因為通過管道輸送到燃氣發電機組的天然氣數量減少了。

與此同時，冬季風暴埃利奧特期間電力需求激增，導致美國一些地區的電力系統緊張。田納西河谷管理局和杜克能源公司在圣誕節前夕在田納西河谷和卡羅來納州實施了輪流停電，以保持電網穩定。

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.
