About Energy Tycoon: Grid Keeper
The evening peak is here. Every window in the city is switching on, the needle is sliding into the red and a storm is rolling in from the harbour. You run the city's power control room. Keep the lights on.
Grid Keeper is a real-time power grid manager. Balance supply and demand through the whole day, send repair crews when lines go down and grow two small districts into a whole city of steam, gas, water, wind, sun and batteries.
BALANCE THE GRID
- Watch the balance needle: supply has to match demand, from the morning rush to the evening peak.
- Ramp up the Old Smoky steam plant, start a fast gas peaker, release water from the dam or set the battery park to Charge, Hold, Discharge or Auto.
- Call Demand Response when every megawatt counts.
- Check the forecast for the next shift and get ready for heatwaves, cold mornings, windless fog and cloudy afternoons.
HANDLE THE CHAOS
15 kinds of events keep every shift different: thunderstorms knock lines down, a plant trips at the worst moment, the whole city switches the kettle on at half time of the big match, a squirrel sits on a transformer (the squirrel is fine). Tap the spark, send a truck through the streets and watch the district light back up. When there is not enough power, choose which district goes dark for a moment. Hospital Hill always comes last.
GROW A WHOLE CITY
- Start with Old Harbor and Riverside, then connect Hilltop, Market Square, Tech Park, Stadium Row, Hospital Hill and Airport Flats.
- 50 investments: wind farms, solar fields, a hydro dam, battery parks, stronger lines, smart substations that reroute power, more trucks, faster crews, smart meters and a dispatcher assistant that runs the routine for you.
- Earn up to three stars per shift, raise the city rating and play through five chapters. Then keep the whole city lit in endless mode.
- While you are away, the night crew keeps the city running and a welcome-back card shows what it earned.
A LIVING CITY, DAY AND NIGHT
Districts go dark and light back up in a wave, trucks drive the streets, wind turbines turn and the skyline glows from dusk to dawn. A step-by-step guide shows each action the first time. Choose Low, Medium or High graphics to suit your phone, and play at 1×, 2× or 3× speed.
GOOD TO KNOW
- Single-player. No account and no sign-in. Your city is saved on your device.
- The game contains ads and optional in-app purchases: one-time upgrades, looks for your trucks, pylons, turbines, skyline and control room, and budget packs. Nothing is needed to finish the game.
- Ads show our other games in a banner and between shifts. Remove Ads, the Chief Engineer Edition, the Utility Pass and the Complete Grid Keeper Collection remove them. Other purchases do not remove ads.
- Reward videos are always optional. With ad removal you get the same capped rewards without a video.
- Budget packs are used up and are not restored on a new device.
- Ten languages: English, Turkish, German, Spanish, French, Portuguese, Russian, Japanese, Korean and Hindi.
If you like power grid games, energy tycoons and city management, take the control room and keep the lights on.

What’s new
Version 1.0.2 · Updated October 31, 2026
• Chapter 1: every shift brings one gentle incident, so the early days are never dull. • Fairer third star: a fault's dark time stops counting once a crew is on the way. • A repaired district's load now comes back gradually over about 10 seconds. • The last running unit no longer trips on over-supply. • Privacy: no analytics event is sent before your consent choice is applied.
