I can’t speak for other countries, but since the article is about Germany: You have never heard of Netzentwicklungsplan, Südlink, Südostlink, Lastmanagement für Ladestationen and many more of these things? The Netzausbau (expansion of the power grid) and Lastmanagement (power distribution management) is pretty much a huge topic for all Netzübertragungsbetreiber and the other smaller power grid operators in Germany. Most of the development is slow at the moment because of bureaucracy and NIMBYs but it is actively being worked on.
