Electricity Demand Growth by Grid Region
Electricity demand over the latest 12 months vs the 12 months before, %
Plays the chart through its history. Pauses are where a new leader takes first place.
EIA Hourly Electric Grid Monitor (Form EIA-930), demand served by the grid as balancing authorities report it, summed by EIA region. Rooftop solar and other generation behind the meter lower it.
Which grids are adding load fastest. The national bar is the benchmark: regions above it are where new demand, much of it data centers, is concentrating.
