eli5: how do electric companies deal with different demands of electric power?

623 viewsOtherTechnology

As far as I know the electric power is produced „fresh“ and transported everywhere via wires. If I turn on a light in my house the demand goes slightly up. Does the power plant then automatically produce more electric power? Or are there huge batteries somewhere that deal with the different demands?

Beyond the solutions the others have given, in some places, they use things like pumping water up when there’s power in excess, and then use that same water to drive turbines when there’s a demand.
