Is Gas Making a Comeback on the US Power Grid?

Why It Matters

The shift revives gas’s role as a flexible bridge fuel, influencing investment, emissions targets, and grid reliability across the United States.

Key Takeaways

• Gas share of U.S. electricity rose to 38% in 2024
• New pipeline projects cut regional gas price spreads
• Utilities add 5 GW of fast‑start gas capacity this year
• Carbon‑capture pilots aim to offset gas‑related emissions
• Coal retirements accelerate, boosting gas’s market share

Pulse Analysis

Natural gas has re‑emerged as the dominant dispatchable resource on the U.S. grid, driven by a confluence of market and policy factors. After a brief dip during the early renewable surge, gas‑fired generation rebounded as coal plants shuttered and battery storage struggled to meet peak‑load demand. The Energy Information Administration’s latest outlook shows gas supplying roughly 38% of electricity in 2024, up from 33% two years ago, underscoring its renewed relevance in a decarbonising mix.

Price dynamics are central to the comeback. Recent expansions of the Permian‑to‑Midwest pipeline network and the reopening of previously idle LNG terminals have eased regional bottlenecks, narrowing the price gap between gas and coal. Spot gas prices have steadied around $2.80 per million British thermal units (≈ $2.60 per MMBtu), a level that makes fast‑start gas turbines economically attractive for utilities confronting hotter summers and higher air‑conditioning loads. Moreover, the Inflation Reduction Act’s tax credits for carbon‑capture technologies are prompting operators to retrofit older gas units, extending their operational life while addressing climate concerns.

The implications for investors and policymakers are significant. Utilities are allocating capital to add roughly 5 GW of fast‑start gas capacity this year, often paired with pilot carbon‑capture projects that could reduce emissions by up to 30% per unit. Meanwhile, the decline of coal—over 30 GW retired since 2020—has freed market share for gas, reshaping the competitive landscape. Stakeholders must balance the short‑term reliability benefits of gas with long‑term decarbonisation goals, as the fuel’s resurgence may set the tone for the next decade of U.S. energy strategy.
