Apparently, Nord Pool just is an electricity exchange market - I was aware those existed. I was more asking for a local electric company which changes prices daily (and allows me to know that before so I can adapt). At least in Germany, I am not aware of anyone offering that kind of contract, and I would love to see how that is implemented elsewhere.

At least in Finland pretty much every electric company offers "pörssisähkö" contracts using either hourly or daily prices. Afaik they all provide an app to see the prices, or you can get them directly from Nord Pool.

Since German prices are on that map, I assume there are at least some companies doing that in Germany too.
