It doesn't work like that. The California failure is a good example. So far energy storage can just do a day-to-day backup for homes and some non-energy-intensive business activities, for others just few hours. No more. At grid scale storage is only a quick buffer to compensate renewables fluctuations waiting for classic power plants to regulate their output.
Even at current Chinese prices a re-backed grid is just a dream and a nightmare only those who do not know electricity could think it's doable, while it's perfectly possible converge to electricity as we have converged to IP, a single tech for nearly all, not the cheapest but the most universal, that on scale means doing more with less, or implementing the new deal, with self-consumption and small scale storage, so we can shift our loads (and we have very sensible economical incentives to do so) as much as possible augmenting the usage of electricity without augmenting the grid loads. Nights will demand more from the grid, but that's not an issue because most loads except in harsh winters that are more and more rare, happen during the day.
This is a logic, technically sound path toward the new deal. The California model is a logic, financial-capitalism sound way to implement the new deal which actually can't happen. Those who think the contrary simply do not understand the scale and the tech we have so far. We can't produce enough storage and using it for such grid-scale loads means breaking it very quickly, not 10 years of a classic LFP but 1-3 years maximum at a scale we can't sustain for more than few years with skyrocketing costs.
The giant want this because they need this to milk people as much as they can, but it's technically impossible and anyone who think the contrary will see what happen in few years if the trend will keep going like today, with more and more rolling blackouts and large stability issues to the point the EU will look like South Africa's grid now.
