So you build out storage facilities. Whatever turns out cheapest for a given site wins. Different sites will favor different winners. We don't know yet which few of myriad choices that all work will turn out cheapest, but probably not batteries beyond a few hours' time-shifting. There is little value in central storage, except in methods where economy of scale rules. Storage can otherwise be distributed as widely as convenience suggests, and the power moved around on wiring. Of course you don't build out storage until you have enough spare renewable generating capacity to charge it from. In the meantime you fill shortfalls from peaker plants, the usual way. As synthetic fuels like hydrogen and ammonia become cheaper than NG, peakers will be fired with them, either synthesized locally or imported, when cheaper storage runs low.
