AI data center planner, from GPU rack to grid connection
NodalZen is a free, open-source planner for AI data centers. Choose a GPU cluster and it
estimates the power, cooling and backup it needs, ranks where in the US it could connect
to the grid, lists the equipment and how long it takes to arrive, and works out the energy
and cost per million tokens. Every result shows its formula, and every data value shows
its source and date.
Four connected steps
Size: IT load, PUE by month, liquid and air cooling, transformers,
switchgear, UPS, battery storage and generators.
Site: US states ranked by electricity price, grid carbon intensity,
interconnection queue wait, water stress and free-cooling hours.
Source: the equipment list, lead times, order-by dates and the critical
path to a target operation date.
Run: tokens per second, energy and cost per million tokens, annual
electricity cost and carbon.
