Wisconsin | Yes, it's mostly hourly or daily electricity storage to meet peak demand, and use renewable energy that's produced when it's not needed. It also provides grid stability, for instance when transmission lines are shut down due to high winds.
Going back and forth from AC to DC and back to AC is remarkably efficient. More efficient than pumped hydro I believe. But also much more costly to build. If the batteries reach 5-10,000 cycles like they claim, then it's remarkably cheap storage. These haven't had time to reach that number of cycles, and it sounds like the whole thing is up in smoke, not much chance of putting something like that out at that point. | |
