My electricity cost currently is split around 1/3 generation (~10¢/kWh) and 2/3 distribution (~20¢/kWh). If the power from this scheme can avoid most of the costly distribution, eg. I use it directly in my house and neighborhood, then it’s an economic win. This would be true even if the centralized generation was free.

It can't, because the distribution fee is an amortized cost of having distribution infrastructure built. Since that infrastructure still needs to exist regardless of where you get your energy (and in fact needs to be upgraded to handle bidirectional consumer/producers), EV storage won't bypass it regardless of where the EV and the consumer is physically located.

If you consume what you store, then you will charge up at low (production prices + distribution fees) for the times when (production prices + distribution fees) are high. The second term is constant so you are arbitraging on production prices.
