There's now greater capacity† in grid batteries than pumped hydro, and the former is increasing rapidly. † note "capacity" has a sometimes misinterpreted meaning here. It means instantaneous generation and/or the opposite how many watts can be taken off the grid for later. Pumped Hydro can discharge for longer, but in a world of cheap intermittent generation, this isn't particularly helpful.
