Until very recently, all power was generated on demand. The amount of power generated and the amount of power consumed had to be exactly equal at all times.
Though now we do have battery farms and other forms of grid-level storage in some places to help balance the variability of renewable sources.

Its interesting being in other countries and you can watch the load / supply change with a standing fan. Speeds up, slows down, lol goes out.
