Balance - Power Grid is a puzzle game about power grids. You place cables, pylons and power generators to make sure there are no blackouts. Through a series of challenges you build power grids that are functional, and that produce the right amount of power.

As you progress you must adjust the level of power for day and night to match the demand. Apply limits on how much power is transmitted through a single power line so it doesn't overload. Build in contingency so that downed power-lines don't bring down the whole system.

You do not need any knowledge about electricity or power grids in order to enjoy this game. Balance is developed by Statnett, the system operator in the Norwegian energy system, and is based on real challenges they work with every day. The game has been very popular on Google Play and now counts over 2 million downloads.
