US-based American Clean Power Association, along with several other organizations including the American Petroleum Institute, Alliance to Save Energy, Clean Energy Buyers Association, Nuclear Energy Institute, the U.S. Chamber of Commerce, and the National Electrical Manufacturers Association, commissioned a study by S&P Global Commodity Insights. The study, titled ‘US National Power Demand Study’, was released on March 7, 2025. It projects a significant growth in electricity demand in the US, driven by manufacturing, data centers, and the electrification of heating and transportation. The study highlights the need for substantial additions to the energy supply, including 60 to 100 GW of gas and over 900 GW of renewables and batteries by 2040. It also emphasizes the importance of energy efficiency and clean firm technologies like advanced nuclear and geothermal in maintaining grid reliability and reducing carbon emissions. The study identifies challenges such as outdated interconnection processes, local opposition, and supply chain constraints, and suggests policy reforms to address these issues. The report also notes that wholesale power prices could be around 20% higher in the short term due to higher gas prices and increased demand.
