???? 據2月19日Hart Energy報道，三名知情人士稱，TC能源公司宣布，由于德克薩斯州嚴寒天氣導致電力中斷，其Marketlink管道的原油交付受到不可抗力的影響。

????德克薩斯州和新墨西哥州的石油生產商、輸油管道和煉油廠已經停止運營，因為他們正在努力應對罕見的嚴寒天氣。嚴寒導致近24人死亡，數百萬人斷電。

????Marketlink管道的產能為75萬桶/天，從俄克拉荷馬州庫欣向南輸送。根據伍德麥肯茲公司(Wood Mackenzie)表示，從華盛頓到德克薩斯州，這條線路與Keystone石油管道系統相連。而Keystone石油管道系統是加拿大原油從阿爾伯塔省北部到美國中西部煉油廠的關鍵運輸通道。

????根據伍德麥肯茲的數據顯示，2月15日，由于德州二疊紀盆地和新墨西哥州(美國最大的頁巖盆地)的嚴寒天氣，超過200萬桶/天的輸油產能被迫關閉。

????TC Energy Declares Force Majeure on Oil Deliveries in Texas

????TC Energy Corp. has declared force majeure on crude oil deliveries at destinations in Texas on its Marketlink pipeline, citing power outages caused by severe cold weather in the state, three sources familiar with the matter said.

????Oil producers, pipelines and refiners in Texas and New Mexico have halted operations as they grapple with a rare deep freeze, which left nearly two dozen people dead and knocked out power to millions.

????The Marketlink pipeline has a capacity of 750,000 bbl/d and flows south from Cushing, Okla., to Nederland, Texas, according to Wood Mackenzie. The line is connected to the Keystone oil pipeline system, a key transporter of Canadian crude from northern Alberta to refineries in the U.S. Midwest.

????More than 2 million bbl/d of pipeline capacity into the Gulf Coast was shut at some point on Feb. 15, according to WoodMac, as freezing temperatures gripped the Permian Basin of Texas and New Mexico, the top producing shale basin in the country.
