> Really? German utilities use batteries for day-night supply/demand smoothing? Yes. https://www.vb-bordesholm.de/batteriespeicher.html https://www.vb-bordesholm.de/batteriespeicher.html > Are you sure you're not confusing this with minute-over-minute smoothing, which requires ~two orders of magnitude less battery capacity? Yes, Frequenzregelmarkt (minute over minute smoothing) and the normal electricity capacity trades happen in two separate markets in Germany right now. Allowing battery storage to take part in both markets is one of the goals of the current coalition government. Since this happened before that change and the article mentions it being involved supplying a city decoupled from the long distance energy transmission it is legally impossible that this battery installation just did minute over minute smoothing. > How many GWH of capacity have they deployed? 4,5 GWh [1] out of which 1GWh is grid scale and industrial use. > And isn't it the country where a KWH costs 33 cents? For normal consumers, yes. Industrial users have a lot lower rates. A lot of this is taxes and similar stuff too. I found conflicting numbers on the precise details but 9-12ct are the used for producing the energy (including profits and investments of those companies), 8-9ct are used for the network (including profits and investments of those companies). The rest are taxes or other kinds of levys.
