About
Kinder Morgan, Inc. is a Houston, Texas-based natural gas pipeline and terminal infrastructure company — publicly traded on the New York Stock Exchange (NYSE: KMI) as an S&P 500 Energy component — owning and operating approximately 79,000 miles of pipelines and 139 terminals transporting and storing natural gas (primary), gasoline, crude oil, CO2, and other products through approximately 9,000 employees across the continental United States. In fiscal year 2024, Kinder Morgan reported revenues of $14.8 billion and Adjusted EBITDA of approximately $8.0 billion — with the Natural Gas Pipelines segment (Tennessee Gas Pipeline, El Paso Natural Gas, Southern Natural Gas) generating 60%+ of total EBITDA through long-term capacity reservation contracts with electric utilities, LNG export terminals, industrial gas consumers, and local distribution companies. CEO Kim Dang (appointed 2023, the first female CEO of a major US midstream energy company) has positioned Kinder Morgan to benefit from the structural natural gas demand surge driven by AI data center electricity consumption and US LNG export expansion: natural gas power plants are the fastest way to add electricity generation capacity for AI data center load growth (an 800 MW gas-fired CCGT can be built in 18-24 months versus 10+ years for nuclear), requiring additional natural gas pipeline capacity to supply new generation — which Kinder Morgan is uniquely positioned to contract for through its existing pipeline corridors.
