FWIW there was a huge surge in energy costs following the war in Ukraine (due to the reduction in supply of Russian gas) which was dampened by the government with a subsidized price cap at 0.40€/kWh - for consumers anyway, as far as I'm aware there were different subsidies for industry.

But consumer prices have largely stabilized at a range of 0.25€ - 0.35€ although you'll also find some prices listed as low as 0.20€ or less if you are willing to price hop a lot.

Apparently there will also be price cuts in the North and East of Germany as well as Bavaria in the near future but I don't know the specifics of that.
