so I have been having sleepless nights about this concept.

From what I understand, say a typical power generating plant that produces 2000MW of energy, for example, will want to transmit as much of 2000 MW of power to the grid as possible and they do so by stepping up the voltages to 500kV or more in order to reduce transmission losses.

Now let's get down to what happens once the distribution company gets this power. Say the voltage is stepped down to 132kV from 500kV.

Now my question is, since there is a huge reduction in voltage, won't that mean that there will be significant loss in power as well due to P = VI?

So what I am saying is that let's say the grid transmits 500 MW of the 2000 MW they receive to one of the distribution companies/utility, then when distribution company distributes at lower voltages, won't that mean they will be distributing much less than 500 MW due to low voltage levels (by low voltage here I mean below 132kV, i.e 33kV, 22kV, 11kV, 415V, etc)? (I am talking about losses due to lower voltage levels due to P = VI, on top of the heat losses)?

Thanks for your help!
