Data Center Gas Plants May Boost US Power Emissions 20%

Data center developers are increasingly opting for bespoke natural gas power plants, a trend that is projected to significantly elevate carbon emissions and complicate efforts by U.S. technology companies to achieve their ambitious climate targets. A Bloomberg News analysis of 99 proposed plants tracked by BloombergNEF indicates that these facilities could collectively emit approximately 318 million metric tons of carbon dioxide per year if operated at standard industry rates. This figure represents a substantial increase, potentially lifting the entire U.S. electric power industry's emissions by 20%, and could reach as high as one-third of current levels if the new plants operate at full capacity. For context, the U.S. electric power sector emitted around 1,485 million metric tons of carbon in the previous year, according to data from the Energy Information Administration. The burgeoning demand for data center construction has already placed considerable strain on the existing U.S. electricity infrastructure, leading to concerns about grid reliability and the implementation of moratoriums on new project approvals in some regions. With even approved data center projects facing multi-year delays in connecting to regulated electricity grids, developers are actively seeking alternative power solutions. These alternatives include "behind-the-meter" projects, which can be permitted and constructed without the need for approval from utilities or the independent system operators responsible for maintaining grid stability. David Pomerantz, executive director of the Energy and Policy Institute, a watchdog organization advocating for renewable energy, stated that there is "immense, immense pressure on the whole sector to get power, and get it fast," adding that developers appear "agnostic if it is clean or dirty." It is important to note that not all of the proposed plants identified in the BloombergNEF data are guaranteed to be built, as the intense competition to meet the seemingly insatiable demand for computing power from AI developers has led to the emergence of some speculative projects and ambitious proposals. The Bloomberg analysis's estimation of potential emissions is based on a total of 126 gigawatts of planned on-site gas generation capacity, as tracked by BloombergNEF, an energy research firm owned by Bloomberg LP. The calculation of the carbon footprint utilized a usage range from an industry average of 60% to a maximum of 100% operational capacity. The rapid expansion of data centers, driven by the AI boom, necessitates significant power generation, leading developers to explore options that bypass traditional grid connection timelines, even if those options involve fossil fuels.
