How are there multiple electricity companies if the power comes from one line?

Question

I don’t understand how there can be multiple electricity companies if the power comes from the same power line.

What I mean is, how is the power I’m getting different from the power my neighbors are getting? It’s the same power, so how can so many different
companies charge different amounts for it?

Basically either all the power is coming from a highly regulated company (regulates by the city usually) it just directly from the city. The other responses seem to explain it well, though
