The Impact of GenAI on Electricity: How GenAI is Fueling the Data Center Boom in the U.S.
Data centers are the modern nerve centers of the digital world, and play a critical role in the storage, management, and delivery of the vast amounts of information that power our interconnected society. This includes cloud computing, big data processing, AI algorithms and, more recently, complex Generative AI (“GenAI”) models. Data center development continues to grow significantly year-over-year to meet the increased demand for digital services driven by advances in technology. The rapid adoption of GenAI-related tools across many industries has accelerated the growing demand for digital services and data centers. Much of this growth will occur in hyperscale data centers – a specialized category of data centers designed to power immense amounts of digital information and computational tasks (including GenAI) at an unprecedented scale.
This growth in demand for data center services, particularly for GenAI, is driving up power usage and density. Data center electricity consumption was 2.5% of the U.S. total (~130 TWh) in 2022 and is expected to triple to 7.5% (~390 TWh) by 2030. That’s the equivalent of the electricity used by about 40 million U.S. houses – almost a third of the total homes in the U.S.
GenAI is expected to account for at least 1% of this increased power usage.
The projected uptick in incremental electricity usage for GenAI is driven by two key factors:
Given the magnitude of electricity needed to power data centers, the question arises: Where will these facilities be located?
Currently, most of the data centers in the U.S. are in PJM and MISO. New builds are also expected in CAISO and Southeast regions. Combined, these four ISOs / regions, will likely host more than 60% of the total data center capacity in the U.S. by 2027. Primary locations for new builds include Ohio, Illinois, California, Virginia, Florida, and Georgia. Decisions about where to build data centers are based on a number of pivotal criteria, including access to lower cost power and energy infrastructure and favorable state tax incentives. Additionally, reliable telecommunications infrastructure is key to ensuring low latency enabling data centers to be located further away from actual use. Environmental factors – such as cooler weather conditions and limited exposure to natural disasters – also play a role.

However, there are several emerging risks and concerns surrounding data centers, including:
Data center owners (primarily major tech companies and colocation providers) have set ambitious clean energy goals to manage these emerging risks. These objectives include:
The expected growth of GenAI and digital technologies create an opportunity for renewable developers and utility players to work with key data center players and provide innovative green energy solutions to help shape the future of data center development in the U.S. These efforts have the potential to make a sizable impact on economic development and support decisive climate actions to reduce carbon emissions and safeguard energy and water supplies.
