GridStrain

America's power grids are under strain.

Data centers and AI are driving the first surge in U.S. electricity demand in decades. Pick a region to see live demand, the real-time fuel mix, and a grid-stress reading — built entirely on official EIA data.

What am I looking at?

Each region is a major U.S. power grid. The colored dot is its Grid Stress Index— how close demand is to the grid's busiest hour of the past year. Green means there's room to spare; red means it's near a record. Open a region to see live demand, the real-time fuel mix, and how much of the power is clean vs. fossil.

Grid Stress Index:
How hard the grid is working vs. its 1-year peak.
Peak Load:
The biggest single hour of demand this week.
Clean Generation:
Share of power from wind, solar, hydro, nuclear & geothermal.
Fossil Baseline:
Power from coal, gas & oil right now.
