Grid operators faced near-critical conditions, prompting FERC commissioner Christie to advocate for reliable energy sources, or dispatchable resources.
The U.S. electric grid is facing significant risks due to coal plant closures, heavy reliance on intermittent renewable energy sources, and increasing demand from data centers and AI technologies. This warning comes from the Department of Energy's (DOE) Resource Adequacy Report, released in July 2025.
To combat potential shortages, the DOE issued an emergency Federal Power Act order in June 2025, targeting the Southeast U.S. to mitigate grid risks. The report emphasizes the urgency of increasing dispatchable energy capacity, power that can be readily controlled and supplied on demand, primarily through America’s abundant natural resources and rapid infrastructure buildout.
The Trump Administration’s 2025 AI Action Plan complements these efforts by prioritizing dispatchable energy sources such as enhanced geothermal, nuclear fission, and fusion, and promoting grid modernization with advanced management technologies, transmission upgrades, and efficient consumption strategies for large users like data centers. The plan also seeks to reform power markets to better align financial incentives with grid reliability.
Regional initiatives like the Southwest Power Pool's Expedited Resource Adequacy Study (ERAS) aim to accelerate adding new generation resources quickly to address dwindling excess capacity and maintain reliability during transitional periods.
Resource adequacy is the central issue facing the U.S., according to Mark Christie, chairman of the Federal Energy Regulatory Commission (FERC). Christie has been vocal about the need for utilities to meet mandatory reserve power supply targets, especially for inverter-based resources like wind and solar, which should be able to ride through frequency and voltage excursions, instead of tripping offline.
Recent events have underscored the importance of this issue. For instance, ISO New England's electricity demand peaked on Tuesday evening at 26,024 MW, the highest level seen since 2013. However, an unexpected loss of generation in the late afternoon on Tuesday led to a "power caution" being issued.
During these extreme heat periods, blackouts could have been deadly, according to Christie. To prevent such occurrences, FERC is reviewing PJM's rules for colocating data centers at power plants, which could be addressed next month.
Despite these challenges, the U.S. electricity consumption reached an all-time high in 2024 and is expected to continue rising. However, clean energy advocates caution that some government analyses may overstate risks by underestimating the contributions of wind, solar, and battery storage resources.
In conclusion, current U.S. policies emphasize emergency regulatory actions, prioritization of dispatchable, reliable generation sources, upgrades and expansions to transmission infrastructure, market reforms for better financial incentives supporting resource adequacy, coordinated regional studies and rapid resource additions to maintain reserve margins, and balancing reliability needs with clean energy integration. The debate over the role and adequacy of renewables and storage continues, as the U.S. navigates the complexities of ensuring a reliable, affordable grid amid rising demands from AI and other growth sectors.
