Power Grid: Idle Energy Tycoon

Repair one broken generator. End up running a fusion reactor.

Power Grid is a small idle game about electricity. Click the bolt to get your first generator working, then build power stations, sell the power and reinvest. Your grid keeps earning while you are away.

Eight kinds of power stations

Solar panels, wind turbines, hydro dams, gas and geothermal plants, offshore wind farms, a nuclear plant and, at the very end, a fusion reactor.

Weather that matters

The weather changes every hour and is the same for every player. Sunny hours help solar, windy hours help turbines, rain fills the dams, and a storm stops the wind. A two-hour forecast lets you plan your next purchase.

Something to do between purchases

• Demand spikes: catch the button for double income or a lump of coins.

• Short goals with rewards, always three on screen.

• Upgrades that double a station type or make your clicks stronger.

Modernize the grid

When you have earned enough, start over with Green Certificates: a permanent bonus to output and clicks.
