From the README

You run a US power grid for one day. Keep it at 60 Hz, or neighborhoods go dark. Play it by hand, or write the dispatch code and race three built-in algorithms.

Online: (add the GitHub Pages link here once it is deployed)

No build step, no dependencies, and the game makes no network calls. Once the page is open it keeps working offline (there is no service worker yet, so reloading with no network won't).

🟩 stable · 🟨 strained (frequency more than 0.2 Hz off for 3+ minutes, or a generator trip) · 🟥 load was shed.
