U.S. Power Grid Reliance on Natural Gas Lifts Midstream Pipeline Volumes
Natural gas supplies 40% of U.S. electricity, driving volume growth for major pipeline operators.
Natural gas currently accounts for 40% of U.S. electricity generation, a share that the U.S. Energy Information Administration projects will remain stable through 2027. This dominance is driven by lower emissions compared to coal and a steady increase in electricity consumption from data centers and air conditioning. Consequently, midstream companies that transport, compress, and store this fuel are positioned to capture sustained volume growth.
Kinder Morgan Inc. and Williams Companies are two large-cap midstream firms directly benefiting from this structural demand. Both operate extensive pipeline networks that move significant portions of the nation’s natural gas output. Their business models rely on fee-based transportation contracts, providing stable cash flows as domestic production and export requirements expand.
Grid Mix Shifts Away from Coal
The U.S. power mix is increasingly defined by natural gas, which outperforms coal, nuclear, and hydropower in contribution to electricity generation. According to EIA data for 2025, coal supplies 16% of power, nuclear 18%, and conventional hydro 6%. Natural gas’s 40% share makes it the single largest source of electricity. This trend underscores the critical role of gas infrastructure in maintaining grid reliability and meeting growing load demands.
The reliance on gas is not temporary. EIA forecasts maintain the 40% share for both 2026 and 2027, indicating a long-term structural shift. As coal plants retire and renewable energy faces intermittency challenges, natural gas serves as the flexible baseload and peaking power source. This ensures that pipeline capacity remains a constrained and valuable asset in the energy sector.
Kinder Morgan Handles Massive Gas Volumes
Kinder Morgan operates the largest natural gas transportation network in the United States. The company’s infrastructure is responsible for moving approximately 40% of all domestically produced natural gas. This dominant position allows KMI to leverage rising consumption without needing to secure new production contracts, as its revenue is tied to the volume of gas moved through its system.
Management projects that U.S. natural gas demand will exceed 160 billion cubic feet per day by 2035. This represents an increase of 46 Bcf/D over 2025 levels. The growth is driven by expanding liquefied natural gas exports and increased power generation to support data centers. Citing Wood Mackenzie, KMI’s outlook confirms that domestic demand will continue to outpace supply growth, supporting higher utilization rates for its pipelines.
Williams Expands Pipeline Network Scale
Williams Companies manages a pipeline network spanning more than 32,000 miles across the United States. This extensive infrastructure enables the transport of significant natural gas volumes from production basins to consumption centers. By focusing on midstream operations, Williams generates stable cash flows for shareholders, insulated from commodity price volatility.
The company’s scale provides a competitive advantage in securing long-term transportation contracts. As the U.S. economy expands and electricity demand rises, Williams’ network becomes increasingly critical to energy security. The firm’s position in the midstream sector allows it to benefit directly from the structural increase in natural gas usage for power generation and industrial applications.
