I’m by no means an expert just trying to think things through logically I could absolutely be incorrect in any of my assumptions.
That being said I believe inverters go up in efficiency as their capacity increases, add this the fact that they need to be over provisioned to allow for peak draw times and it makes sense that a substation that averages a neighborhoods demand would be able to cut down on cost by averaging.
I’m not qualified to answer but I do know there are losses in transmission and ac/dc conversion for that transmission.
