America's electric grid is facing a growing reliability problem, with aging infrastructure and severe weather events leading to more frequent and longer power outages across the country. The U.S. grid performs far worse than many other advanced economies when it comes to reliability, measured by the System Average Interruption Duration Index (SAIDI). While some states experience less than an hour of annual outage time, others can exceed 500 minutes. This variation is due to the highly decentralized nature of the U.S. electric grid, with over 3,000 utilities governed at the state level. As electrification continues to expand, reliable electricity infrastructure is becoming even more critical to economic growth and prosperity.

Why it matters

A reliable electric grid is the foundation for a modern economy, powering everything from hospitals and transportation to communications networks and financial systems. However, the U.S. grid is becoming increasingly vulnerable, with power outages occurring more frequently, even outside of major storms. This poses a significant threat to economic growth and stability as electrification continues to expand, with demand for electricity expected to surge in the coming years.

The details

The Blizzard of 2026 in the Northeast left over 600,000 homes and businesses without power for days, highlighting the grid's vulnerability to severe weather. While this was an extreme event, power outages have become more common, with the average customer experiencing nearly double the outage hours of a decade ago. The root cause is not just the weather, but the decentralized structure of the American electric grid, with over 3,000 utilities governed at the state level by Public Utility Commissions. This has led to dramatically different reliability levels across the country, with some states experiencing less than an hour of annual outage time while others exceed 500 minutes.

  • The Blizzard of 2026 swept across the Northeast in February, leaving over 600,000 homes and businesses without power for days.
  • In 2024, the average customer experienced nearly double the outage hours of a decade ago.

The players

Public Utility Commissions

State-level regulatory bodies that oversee the distribution portion of the electric grid, determining investment approvals, rate structures, and infrastructure upgrades.

Data centers

Analysts project that power needs for data centers alone will triple by 2030, making reliable electricity infrastructure even more critical to the AI era.

What’s next

The choices made today about where and how to invest in the grid will shape the reliability and prosperity of the American economy for decades to come.

The takeaway

Improving the reliability of the U.S. electric grid is crucial for supporting economic growth and prosperity in the years ahead, as electrification continues to expand and the demand for reliable power surges. Addressing the decentralized structure of the grid and investing in infrastructure upgrades will be key to ensuring the lights stay on, even in the face of severe weather events.
