Hopefully long term, this can help us dismantle unnecessary high voltage transmission lines, and let people trickle store power at 48volts and discharge it at 110 through inverters.
edit: Sliced bread was invented in 1928, and the first high voltage transmission line was apparently tested in 1889. Therefore my statement needs revised to be historically accurate.
But I can't see that working on denser cities, or factories, or less sunny climates.
Houses mostly, the reason we need such high voltage is because someone can turn on an oven and consume 5kw. But that oven only runs for 1 hour, or more averagely, 30 minutes. So in the context of 200kwh battery systems at EVERY house, and inverters at every house, that oven can easily run off the inverter, and the house would never need to pull down heavy wattage from the grid. In this scenario, the grid's variability goes down dramatically, thus, reducing the voltage requirements... Instead every house would have small solar and a trickle feed of, lets say 800w-1kw consistently during the day.
Additionally, for places that have a shit-ton of sun, can do much better with microgrids and generators.
Look, I'm not wrong about this, it just would require all houses to have their own inverters and batteries. I'm not saying this is GOING to happen, I'm just saying the requirements on the grid would be so damn small that having a PG&E would be hilariously expensive in this possible future. Instead you would have microgrids and much smaller scale power companies.
If you all want to keep paying $1 per kwh (2026 pricing) by all means don't push for this kind of infrastructure change. If people want $0.01 per kwh again, this is the way to do it. At this point we're mostly paying for PG&Es infrastructure that makes sense in today's batteryless world. We don't have to keep paying that price. There are different futures and more competition possible.
What for? If I were to run a heat pump, car charger, oven and electric shower all at the same time that would be about 25kw
What load do you imagine causes "most" homes to exceed 100 kW, and "some much higher"?
There is a reason why pipelines are popular even though we have the capability to move oil using normal transportation.
