Market Dynamics

Drivers - Natural Gas Achieves Record Consumption as the Structural Backbone of U.S. Power Generation

Natural gas has evolved from a supplementary fuel to the indispensable backbone of U.S. electricity supply, underpinned by two decades of shale-driven domestic production growth and progressive fuel switching from coal. Its flexibility, price competitiveness, and high combustion efficiency have made it the preferred dispatch fuel for the U.S. Thermal Power Market across both seasonal peaks and baseload requirements.

In 2024, U.S. natural gas consumption reached a historic high of 90.3 Bcf/d, with the electric power sector alone accounting for 41% of total national gas use, rising 4% (1.6 Bcf/d) year-over-year, as historically low prices improved its dispatch economics relative to coal. Natural gas achieved a record 43% share of total U.S. electricity generation in 2024. By 2025, the annual average price recovered to $3.52/MMBtu, a 56% year-over-year increase signalling supply-demand normalisation as LNG export capacity added an estimated 3 Bcf/d of structural demand. Since 2017, U.S. natural gas production has consistently exceeded domestic consumption, and in 2023, domestic output reached approximately 39 quads (38% of total primary energy production), reinforcing long-term energy security and fuel supply reliability for thermal power operators.

Extreme Weather Cycles Drive Sustained Peak Electricity Demand Across Thermal Generation Assets

Weather conditions function as the single largest short-term driver of electricity generation demand in the United States, directly determining dispatch volumes and fuel burn rates across the U.S. Thermal Power Market. Polar vortex events in winter and prolonged heat waves during summer consistently expose the limitations of intermittent generation, reinforcing the irreplaceable dispatch role of thermal power assets in grid balancing.

January 2024 natural gas consumption surged 12% year-over-year due to severe winter heating demand, while July 2024 consumption rose 3% on the back of elevated summer cooling loads. The summer of 2024 ranked as the fourth warmest on record across the Lower 48 states, pushing electric power sector gas consumption to record highs in July and August. U.S. electricity generation was up 6.3% in the first four months of 2025 compared to the same period in 2024, reflecting a sustained upward trajectory in total grid demand. Toward year-end 2025, a polar vortex event in late November–early December temporarily pushed natural gas spot prices above $5.00/MMBtu, with Algonquin Citygate averaging $16.37/MMBtu in January 2025 and $14.00/MMBtu in February 2025, the highest monthly averages since 2022. These recurring demand spikes systematically validate continued investment in dispatchable thermal capacity.

Geopolitical Energy Supply Risk Reinforces the Strategic Value of Domestic Thermal Infrastructure

Heightened geopolitical tensions, particularly the escalating conflict involving the United States, Israel, and Iran, have placed renewed emphasis on the strategic importance of domestically controlled thermal power generation capacity. Supply disruptions affecting global energy transit routes directly translate into domestic fuel price volatility, amplifying the economic and energy security arguments for maintaining and optimising existing U.S. Thermal Power Market infrastructure.

The Strait of Hormuz, through which approximately one-fifth to one-quarter of global oil and a significant share of LNG exports transit, represents a critical global energy chokepoint that rising conflict risk has made increasingly uncertain. U.S. crude oil production reached an all-time monthly record of 13.4 million barrels per day (b/d) in August 2024, with annual production forecast to reach 13.5 million b/d in 2025, partially insulating domestic fuel supply chains from external shocks.

Global oil price benchmarks remain tightly correlated with domestic wholesale energy prices. Historically, energy supply disruptions tied to geopolitical events have contributed to inflationary pressure and economic slowdowns in the United States. This risk environment reinforces the case for domestic thermal power capacity as a fuel-flexible, grid-stable hedge against international supply volatility, particularly for high-load industrial consumers and grid operators prioritising reliability-of-supply over cost minimisation.

Restraint - Structural Coal Plant Retirements Reduce Long-Term Thermal Generation Capacity

Coal-fired generating capacity across the United States is in irreversible structural decline, constrained by environmental compliance obligations, carbon emissions regulation, and the sustained price competitiveness of natural gas.

The U.S. EIA projects coal generating capacity to fall from 177.1 GW in Q4 2023 to approximately 162 GW by the end of 2025, as plant retirements accelerate significantly. Total coal stocks in the electric power sector declined from 116.4 MMst to 105.4 MMst during Q3 2025 alone, reflecting tighter fuel balances even as generation temporarily rebounded. The irreversible contraction in coal capacity represents a meaningful long-term constraint on the fuel diversity of the U.S. thermal power fleet, limiting grid operators' ability to deploy coal as a swing generation resource during high-demand periods.

Pipeline Infrastructure Constraints and Regional Bottlenecks Limit Generation Dispatch Efficiency

Persistent transmission and pipeline infrastructure limitations constitute a structural barrier to optimising the economic performance of U.S. thermal generation assets. Regional supply constraints, particularly in the Northeast, have repeatedly caused price spikes at key trading hubs, undermining cost predictability for thermal operators.

The U.S. combined-cycle gas turbine (CCGT) fleet declined by nearly 2,000 MW since 2023, with no new capacity additions in the preceding 16 months, creating additional dispatch headroom for coal during periods of constrained gas infrastructure availability. Algonquin Citygate and Transco Zone 6 NY spot prices surged to multi-year highs in early 2025 due to cold weather events compounded by pipeline bottlenecks, highlighting how infrastructure deficiencies translate directly into market risk for thermal power generation economics.

Opportunity - Combined-Cycle Natural Gas Capacity Development to Serve AI-Driven Data Centre and Industrial Power Demand

The rapid deployment of AI computing infrastructure and hyperscale data centres across the United States is generating a structurally new category of large, continuous electricity demand, one that requires the reliability, dispatchability, and capacity scale that only thermal power generation can readily provide. This trend represents a compelling long-term growth vector for the U.S. Thermal Power Market, linking digital infrastructure investment directly to new thermal power plant development.

In December 2025, NextEra Energy Resources, LLC and Basin Electric Power Cooperative signed a Memorandum of Understanding to jointly explore the River Run Energy Center, a proposed ~1,450 MW combined-cycle natural gas-fired power plant in North Dakota, submitted to the Southwest Power Pool for expedited resource adequacy evaluation under Basin Electric's Large Load Commercial Program explicitly designed to serve data center and high-load industrial demand. As AI infrastructure and manufacturing facility deployments intensify across multiple U.S. regions, thermal power developers with access to capital, fuel supply, and transmission interconnection rights are positioned to capture long-term contracted generation revenue from this high-reliability demand segment within the U.S. Thermal Power Market.

Natural Gas Supply Chain Integration Enhances Fuel Security and Cost Competitiveness for Thermal Operators

Vertical integration across the natural gas value chain, encompassing upstream supply, midstream storage, and fuel delivery logistics, represents a high-impact commercial opportunity for thermal power generators seeking to insulate their operations from regional price volatility and tightening LNG export-driven supply dynamics. Control over midstream infrastructure directly strengthens the operational and financial resilience of gas-fired generation assets within the U.S. Thermal Power Market.

In December 2025, NextEra Energy Resources, LLC announced the acquisition of Symmetry Energy Solutions from Energy Capital Partners, expanding gas supply, storage, and asset management capabilities across 34 U.S. states. This transaction reflects a broader industry trend toward fuel supply security as LNG export demand expanded by an estimated 3 Bcf/d in 2025 following new export terminal capacity additions, tightening domestic supply-demand balances.

U.S. natural gas production has exceeded domestic consumption every year since 2017, reaching approximately 39 quads in 2023, but mid-continent supply access and storage positioning remain critical determinants of dispatch cost for individual thermal operators. Integrated midstream ownership reduces basis risk and operational vulnerability to weather-related supply disruptions.

Grid Modernisation and High-Voltage Transmission Investment to Unlock Thermal Generation Asset Value

Expanding high-voltage bulk transmission infrastructure presents a strategic opportunity to extend the commercial dispatch range and economic efficiency of large-scale thermal power plants, directly improving the return profile of existing generation assets within the U.S. Thermal Power Market. Projects that materially increase power-transfer capacity between generation-rich and demand-constrained regions are essential to realising the full economic value of installed thermal capacity.

In February 2026, the PJM Interconnection Board of Directors approved the development of an approximately 220-mile, 765-kV transmission line across West Virginia, Pennsylvania, and the Mid-Atlantic region, jointly developed by NextEra Energy Transmission, LLC and Exelon Corporation. The 765-kV architecture can transmit 2–3 times more power than comparable 500-kV systems while reducing transmission losses by up to 50% directly improving dispatch economics and revenue certainty for large-scale fossil-fuel power plants connected to the corridor. Addressing transmission bottlenecks through capital investment, such as this PJM-recommended project, strengthens long-term grid reliability and enables sustained operation of thermal generation facilities amid the Northeast's structurally constrained energy infrastructure.
