That could explain it if prices were high in general (i.e. also for industry).
https://de.statista.com/statistik/daten/studie/152973/umfrag... shows that 2014-2021 over six cents per kWh were going to the renewable energy subsidy scheme, and this is directly attributable, not some kind of hand-waving. I believe this was more than the wholesale cost of the electricity (without grid fees and taxes) in many of these years, and I think you also have to add another 19% of VAT on top of that.
In 2022 the subsidy started to be paid from taxes instead, and it was lower because market-based electricity prices went up (reducing the amount of subsidy necessary to reach the guaranteed prices).
