I'm not sure there are (can be?) enough batteries in the world, to support the grid for any length of time.

  There was a project to try this: https://www.greentechmedia.com/articles/read/german-utility-plans-a-flow-battery-big-enough-to-power-berlin https://www.greentechmedia.com/articles/read/german-utility-... Unfortunatly this project was cancelled since Germany taxes electricity from batteries two times: Once when charging the battery and once when discharging it (since it is then seen as "producing" electricity).

    Why wouldn't this be solved by co-locating the battery with its own generator?

  There are not now but there may be a solution in the future eg "Seasonal energy storage in aluminium for 100 percent solar heat and electricity supply" https://www.sciencedirect.com/science/article/pii/S2590174519300157 https://www.sciencedirect.com/science/article/pii/S259017451...
