How the build-out compounds
Each announcement lands on a grid and gas system that is already carrying everything before it. This timeline stacks the 87 tracked campuses year by year, so you can see the load add up to 2030.
Each year stacks on the last
Every column is the total expected load running that year. Lower layers are load already online; the outlined layer at the top is what that year adds. Select a column to see which campuses arrive.
Against the system that exists today
The question for every utility and pipeline is not the size of one campus but the sum of all of them, measured against the capacity already in place.
United States
PJM, the largest exposure
ERCOT, where the queue is five times the peak
Alberta, where requests exceed the grid

Campus by campus
The largest campuses by expected load, with the megawatts each is modelled to add per year. Black cells are load already running.
| Campus | Status | Thru 2025 | 2026 | 2027 | 2028 | 2029 | 2030 | Total MW |
|---|
Dated milestones
The events behind the curve: what came online, what was announced, and the price and tariff responses that followed. These dates are reported, not modelled.
How the years are modelled
Each campus's expected MW by 2030 (from the index) is spread across years by build stage. Totals match the index; only the timing is assumed.
| Build stage | Campuses | Timing of expected load |
|---|
Next pass. We will look up each campus's announcement date, groundbreaking and first energization, and replace these modelled years. Rows without a public date will keep the modelled timing and be flagged.

The index lists all 84 campuses with their status, power supply, gas draw and impact rating.
