I have that question. I am not asking about the voltage or electric potential difference. I guess the answer will depend on what type of generator is used in the power plant: maybe synchronous. Can the potential of each of the 2 points be a function of time? I know you have the answer. Thanks in advance.

Sure since the difference in potentials is a function of time the potentials must change. However we have no way to measure it because what is absolute 0 potential?

There is no absolute reference for electric potential, so only potential differences are measurable and physically meaningful.
You can't ask about the electric potential without defining some point to have a potential of 0 and then determining the potential difference relative to that point.

If you are talking about an alternating current (AC) source, then by definition at least one of the conductors has a potential that varies as a function of time.
