I'm pretty sure this price is before taxes (and maybe more payments) and german taxes are pretty heavy, ca. 30% of the consumer price is taxes and stuff, ~25% go to the network operator and only ~45% are power generation[1](~the prices in the visualization). So you have to roughly double that to get consumer €/kWh (ofc daily prices are a bit different than a contract over a whole year).

California is near the same cost as hawaii. The rates are absurd. With the rate payer bailing out their past dividends and lack of investment.
