Hydroelectric Sim
๐ A realistic and fun hydroelectric dam control-room simulator.
You're the sole operator of an island-grid hydro station, and the whole town is counting on you. Start the turbines, synchronise them to the grid, and hold the frequency dead on 60 Hz — because generation has to match demand every second or the lights flicker.
It's a real control room, modelled on how these plants actually run: wicket gates and governors, synchroscopes and breakers, reservoir hydraulics, bearing temperatures, transformer loading, and protective relays that will trip you if you get sloppy. Calm and watchable at first — genuinely tense when the storm rolls in.
โ๏ธ What you'll do
- ๐ Start, spin up and synchronise generating units — auto-sync or match the scope by hand
- โก Balance generation against demand to hold 60 Hz; share load across units on droop
- ๐ง Manage the reservoir: ride out floods, ration through droughts, honour downstream flow and licence limits
- ๐ Follow live grid dispatch — hit the pool's target export for compliance pay, and cash in on price surges
- ๐จ React to system frequency events when a neighbouring plant trips — arrest the dip and earn a response bonus
- ๐ง Handle equipment faults, stuck breakers and relay misoperations — dispatch repair crews before they cascade
- ๐ Recover from a station blackout with a black-start diesel and a dead-bus close
- ๐ฐ Play the market: spot price, water value, ancillary services — the reservoir is a battery, so arbitrage it
๐ฎ Scenarios & difficulty

A built-in interactive tutorial walks you through the whole operating loop on the live plant, and a full in-game guide explains every system. No install, no sign-up — just open it and run the dam.
