  • What’s wrong with that? The entire point of subsidies it to encourage people to do something that’s not currently very economical.

    That the guidelines allow for fossil gas power plants. So basically battery storage has to compete with free power plants with maintenance also being paid by the government.

    Yes day to day selling is profitable. However dunkelflaute is about two weeks a year in Germany. If you want to do that cheaply, you could just use biomass in the current coal power plants. That can be done pretty cheaply. I know biomass has issues, but they are certainly less bad, then building new gas power plants.


  • They are already working on it. The new storage subsidies they are working on require use a week long storage base line, which is too long to be sensible for batteries. Those are fairly expensive per unit stored, but have relatively low losses. So perfect for short term or daily storage, but less good for an entire week. A good system combines both. Short term storage for the night and long term using hydrogen or biomass for dunkelflaute.


  • Pricing zones help match the reality in the power grid to the electricity market in a geographical sense. That still means infrastructure has to be built. For example today the weather is generally sunny in Germany, but there is little wind. Being able to store a good bit of the electricity for the night, when the sun is not shining, would really help a lot. Also if you use pricing zones, that probably would lead to more connections between the zones being built.





  • Walmart doesn’t exist in Europe. How come?

    Walmart has a huge variety of products, which are low value dense and need to be restocked a lot. At the same time people are generally price sensitive. Delivering a full truck of a single brand of say frozen pizza to a store is probably overkill. As in it requires a lot of storage space in the store until it is sold. That increases cost. So you need to take in the truck into a distribution centre and then send trucks with all kinds of frozen products to multiple stores. That creates a pretty strong moat. Combine that with culture and branding and it becomes really hard to enter a market.

    If you have fewer products to sell, that becomes a lot easier. McDonalds has been able to set up restaurants all over the world. Thanks to having a pretty limited number of products to sell. That is also how German supermarket brands like ALDI and LIDL have been able to conquer most of Europe.




  • Zum Glück ist VOLT eine wählbare Partei.

    Die AfD ist in Sachsen-Anhalt kurz davor die absolute Mehrheit zu holen. Volt ist wahrscheinlich am nächsten zu den Grünen und die sind in Sachsen-Anhalt laut Umfragen bei 4,6% also unter der 5% Hürde. Wenn die Grünen reinkommen, gibt es recht sicher keine absolute Mehrheit für die AfD.

    Von daher bitte nicht Volt wählen. Die waren bei der Bundestagswahl in Sachsen-Anhalt bei 0,6%.
