With distributed generation and storage, yes, it's plausible to have periods of 0MW grid demand.

The kinds of consumers you have are not a fixed quantity; particularly their on-site use, generation, and storage patterns all vary over time.

I'm talking about 0 MWh for the entire grid, which includes all of the distributed generators. So, by definition, shutting down each and every piece of electric equipment connected to the entire grid. You truly believe that is a tenable position?

If not, than you must accept there exists some necessary base load. That can be provided from base production like it is today, or it could theoretically be provided from storage and over-production in a hypothetical renweables-only grid.

It's unlikely to hit 0 even at night, no reason to stop all the windmills and hydro, and there will be stored energy buyers and sellers. But there won't be production guarantees to some level based on anticipated demand.

I know it's unlikely, but the point was that there exists some minimum need of energy, even in the most flexible grid imaginable, some base load necessary.

Technically yes, I guess the grid has to be kept energized to work.
