What real Virginia data shows
Every hour of PJM's real fuel mix, matched with Ashburn's real weather, then replayed two ways: run immediately, or let Wetbulb choose.

The priority trade-off
01 · SENSE
Read the air
Temperature and humidity at the cooling tower's intake become a wet-bulb temperature: how hard evaporative cooling has to work.
02 · FORECAST
Price every hour
Ashburn's weather forecast and PJM's grid mix give each of the next 24 hours a water cost and a carbon cost.
03 · SHIFT
Run at the right time
Flexible AI jobs move to the window with the lowest combined cost, weighted by what you care about.
