what happens to excess electricity produced on the grid

1.42K viewsEngineeringOther

Since, and unless electricity has properties I’m not aware of, it’s not possible for electric power plants to produce only and EXACTLY the amount of electricity being drawn at an given time, and not having enough electricity for everyone is a VERY bad thing, I’m assuming the power plants produce enough electricity to meet a predicted average need plus a little extra margin. So, if this understanding is correct, where does that little extra margin go? And what kind of margin are we talking about?

Think of the electrical network as a tightly wound bundle of strings. If you wind faster than what’s connected can turn then the strings coil up a bit but the extra winding pushes back against you, so you slow down winding because it’s harder. It’s not a perfect analogy but it sort of works.
