The North American Electric Reliability Corporation (NERC) has issued a stark warning: over half of North America faces an elevated or high risk of energy shortfalls in the next five to ten years.  This alarming projection is primarily driven by surging electricity demand from artificial intelligence (AI) data centers and the electrification of buildings and transportation, coupled with the accelerated retirement of traditional power plants.

Escalating Electricity Demand

The rapid expansion of AI technologies and data centers is significantly increasing electricity consumption. Data centers alone are projected to consume up to 9% of annual U.S. electricity generation by 2030, doubling their current consumption.  This surge is compounded by the electrification of buildings and transportation sectors, further straining the power grid. John Moura, NERC’s Director of Reliability Assessment and Performance Analysis, emphasized, “We are seeing demand growth like we haven’t seen in decades.”

Insufficient Infrastructure Development

Despite the escalating demand, the development of new electricity generation infrastructure is lagging. NERC’s 2024 Long-Term Reliability Assessment highlights that well over half of the continent is at elevated or high risk of energy shortfalls over the next 5 to 10 years.  The report identifies 78 gigawatts (GW) of confirmed generator retirements, with an additional 37 GW announced for retirement through 2034. This trend is particularly concerning as traditional power plants are being retired faster than new resources are being developed.

Regional Vulnerabilities

Certain regions are more susceptible to power supply shortfalls. The Midcontinent Independent System Operator (MISO), overseeing the grid in 15 states, is at high risk of shortfalls even during normal peak demand periods. Other areas, including PJM Interconnection, ISO New England, Texas, and California, face elevated risks, especially during extreme weather conditions.

Economic Implications

The imbalance between supply and demand has significant economic repercussions. Analysts predict that the increasing load from data centers could drive an “extraordinary” rise in U.S. electricity bills. The Electric Power Research Institute estimates that data centers could consume 9% of the United States’ electricity generation by 2030, up from 4% today.  This surge in consumption necessitates substantial investments in grid infrastructure to maintain reliability and manage costs.

Future Outlook

To address these challenges, NERC recommends reassessing the pace of generator retirements and accelerating the development of new resources and transmission infrastructure. The organization underscores the urgent need for a balanced approach that ensures grid reliability while accommodating the rapid growth in electricity demand. Without decisive action, the U.S. power grid may face increased congestion, higher costs, and reduced reliability, potentially hindering economic growth and technological advancement.

The convergence of rising electricity demand from AI data centers and electrification, alongside the accelerated retirement of traditional power plants, poses a significant threat to the stability of the U.S. power grid. Proactive measures are essential to enhance infrastructure development, manage demand growth, and ensure a reliable energy future.
