Datacenter Twin Lab

A reproducible, local-first power-continuity what-if simulator.

A generator fails. How long does the battery last?

In the opening synthetic example, a 100 kWh battery serves a 1 MW load for 307.8 seconds after utility and generator fail. Utility returns at 900 seconds elapsed. Change the battery reserve to compare depletion and recovery, then export the calculation.

The interactive interface starts automatically when its scripts load. The hosted demo needs JavaScript and WebAssembly and downloads about 14 MB on its first visit. Calculations run on your device; no account is required.
