Page | 012 Scale and Shape of Demand Scale and Shape of Demand Estimates vary, but most agree the potential scale of data center demand is extremely large. Many observers forecast at least 15 GW to 30 GW of new data center demand will be added to the U.S. system by 2030, with a theoretical upper limit 11 of 70 GW based on worldwide microprocessor fabrication limitations.12 The growth of AI is expected to be a major driver; AI has represented half of data center power demand growth since 2016, and this share is predicted to increase through 2030.13 Figure 2: Range of Select Projections for U.S. Data Center Growth14 AI energy demand can be categorized into the two major phases of an AI’s lifetime: training and utilization (also known as inference).15 During the training phase, the AI program is digesting vast amounts of data to build the associations needed for the model to work. This typically has consistently high power requirements. During the utilization phase, the completed model is responding to user queries and performing its actual task. The exact scale of this growth depends on several independent factors in the energy-to-AI value chain, which is a multi-step process of transforming energy into compute and ultimately into completed AI tasks with economic value. Forecasts are sensitive to changes in these factors, as a modification to a step in the process, such as an efficiency improvement, can have a significant impact on total energy demand. 11 As NVIDIA’s servers could be sold anywhere globally, the upper end of the forecast assumes the US has the lion’s share of the growth. 12 Alex de Vries. “The growing energy footprint of artificial intelligence.” Cell: Joule. 10 October 2023. https://doi.org/10.1016/j.joule.2023.09.004A 13 John D.

E3 estimates data center capacity from energy estimates or vice versa using an assumed 86% data center load factor and, where applicable, linearly extrapolates projections to estimate changes from 2023 to 2030. BCG’s “US Data Center Power Outlook” report issued in July 2024 provides its more updated view, projecting new data center demand growth ranging from 60 to 90 GW 2023-2030.
