Electricity absolutely does not balance itself. Passively, the energy that goes into the grid must come out somewhere. Electrical utility companies manage this with two major levers: 1) Standby power plants, that are running but not producing at full load. The plant load is actively adapted to the monitored needs of the grid. 2) Hydroelectric storage, to soak up excess production, where hydroelectric dams with secondary reservoirs are available. Grid load management is very much an active process, not a passive self-correcting one.
