Kinder Morgan also stores or handles a variety of products and materials at their terminals such as gasoline, jet fuel, ethanol, coal, petroleum coke, and steel.

[6][1][7] The company previously had built a major presence in Canada with the Trans Mountain pipeline, but that infrastructure is now publicly owned and operated.

After Kinder was denied an expected promotion to replace Kenneth Lay as chief executive officer, he departed the company, purchasing its interest in ELP for $40 million.

[13] In October 2011, Kinder Morgan Inc. agreed to buy El Paso Corp. for $21.1 billion and gave the combined company 67,000 miles (108,000 km) of gas lines, eclipsing Enterprise Products Partners LP as the biggest US pipeline operator.

[20] During the 2021 Texas power crisis, Kinder Morgan posted a nearly $1 billion one-time net profit after the company voluntarily cut back on its own power (saving $116 million) and sold natural gas to electric utility companies at high prevailing prices (gaining $880 million).

"[21] Most of the extra gas Kinder Morgan sold went to electric utility companies whose usual non-Kinder suppliers had shut down or blacked out as the catastrophe intensified.

[21] El Paso Corporation was purchased in 2012 with subsidiaries: Kinder Morgan owns or operates approximately 83,000 miles (134,000 km) of pipelines transporting primarily natural gas, crude oil, and petroleum products.

In 2013, Kinder Morgan filed its application to the Canadian National Energy Board (NEB) for building a second pipeline roughly parallel to the existing Trans Mountain, for transporting diluted bitumen between Edmonton, Alberta, and Burnaby, British Columbia.

[29] The Liberal Party of Canada controlled Canadian government then purchased TransMountain from Kinder Morgan for C$4.5 billion to make it a government-run public works project in an effort to save the pipeline from environmental and political opposition.

[31] But in 2016, Kinder Morgan suspended its effort to build the 412-mile (663 km) NED pipeline, citing economic difficulties and lack of distribution commitments for the gas.

[39] Also in 2011, the U.S. Department of Transportation cited Kinder Morgan for violations including the company's failure to have and follow written startup and shutdown procedures, and failing to have or use other measures to detect abnormal operating conditions, and proposed a fine of $425,000.

[43] PHMSA's incident reports for Kinder Morgan's onshore gas transmission pipelines show that faulty infrastructure causes 45% of the significant leaks.

[44] In Texas from 2003 to 2016, Kinder Morgan experienced at least 48 "significant incidents" resulting in fatalities or hospitalization, fires, explosions, or spills.
