Market Dynamics & Trends

The US thermal power market is shaped by several key dynamics and emerging trends, which influence its growth and evolution.

• Energy Transition and Decarbonization: While thermal power has long been reliant on fossil fuels, the growing emphasis on decarbonization and reducing carbon footprints is driving change in the market. The US government’s climate policies, such as the Biden administration’s goal to achieve net-zero emissions by 2050, are influencing the energy transition, which is reducing reliance on coal-fired plants in favor of cleaner options like natural gas and renewables.
• Advancements in Clean Coal and Carbon Capture Technology :There have been ongoing developments in clean coal technology and carbon capture and storage (CCS), which aim to mitigate the environmental impact of coal-based thermal power plants. The successful implementation of these technologies could provide a more sustainable future for coal-fired power generation, particularly in regions where coal remains a key source of energy.
• Rising Demand for Natural Gas :The natural gas sector has seen significant growth in the past decade, driven by its lower emissions and higher efficiency compared to coal. The US has abundant natural gas reserves, and its use in thermal power generation is expected to increase, especially as older coal-fired plants are phased out. Natural gas is expected to be a transitional fuel, bridging the gap until renewable energy sources become more dominant.
• Energy Security and Independence:The US has prioritized energy security and independence, particularly in the context of global geopolitical events and fluctuations in energy prices. The use of domestic resources, such as natural gas, has contributed to a more secure energy supply, reducing reliance on imported energy sources and ensuring the stability of the electricity grid.
• Increased Focus on Energy Efficiency :As energy efficiency becomes a top priority in the US, thermal power plants are adopting more advanced technologies to enhance their efficiency and reduce fuel consumption. The increasing implementation of combined heat and power (CHP) systems and the rise of combined cycle power plants are helping to improve the overall efficiency of thermal power generation.

Growth

The US thermal power market is expected to grow at a CAGR of 1.8% from 2025 to 2034, reaching a market size of USD 249.16 million by 2034. Several factors contribute to this growth:

• Energy Consumption Growth :Despite the increasing adoption of renewable energy, the overall demand for electricity in the US continues to rise due to factors such as population growth, urbanization, and industrialization. Thermal power remains a key part of the energy mix to meet base-load demand, especially during peak consumption periods.
• Technological Advancements :Technological advancements in power generation, including combined cycle plants and fluidized bed combustion systems, are improving the efficiency and environmental performance of thermal power plants. These technologies allow for better fuel utilization, reduced emissions, and lower operational costs, enhancing the attractiveness of thermal power generation.
• Government Support for Clean Energy Transition :The US government is providing support through various incentives, subsidies, and regulatory frameworks that promote cleaner energy solutions, including thermal power technologies that reduce emissions. Tax incentives for natural gas plants and investments in clean coal technologies are helping facilitate this transition.
• Shift Toward Natural Gas :The shift from coal to natural gas, driven by its lower emissions and operational cost-effectiveness, will continue to support the growth of the natural gas-based thermal power sector. The expansion of natural gas infrastructure and its competitive pricing will play a key role in sustaining growth in the thermal power market.
