Dashed: the projection from the latest reading. A projection, not a promise.

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. Each point compares the twelve months ending in that month with the twelve before.

The two grids at the centre of the data center build-out against the national pace. PJM carries Northern Virginia, the largest data center market in the world; Texas has the fastest-growing queue of large loads.
