Agreed in theory, but we're honestly just not there yet. In fact the large grid-size batteries aren't even a 1/10 of a percent of grid capacity. Getting enough batteries to cover hundreds of GW of demand ain't cheap.
- natch 8y agoCoal is not exactly cost-free either. And you don't need to match the grid capacity... that's a red herring. Even a tiny fraction of the grid capacity having battery backup is enough to have a disproportionate positive effect on grid stability.
- 3rdAccount 8y agoNever said coal was cost free. Economically coal flat out loses. Everyone knows that and it isn't relevant to the discussion of grid reliability/resiliency. A tiny fraction of grid capacity having battery backup would be nice. Well, technically they already have lots of batteries and auxillary power, but you're talking about really big batteries I assume. Regardless, the answer in the short term isn't get rid of coal and replace with batteries and more renewable. Indeed that will most likely happen in the long-term, but not in the ~5 year frame.
