The 39ct/kWh are an artifact of the European gas crisis 2022, nowadays were closer to the still high 30ct/kWh as before. For a long time renewable energy was subsidized directly from (household) electricity prices. Same is true for grid investments, which are drastically rising, partly due to Windpower being produced in in the north and used in the south.

IMHO part of the problem is definitely due to shutdown of nuclear, rapid expansion of renewables while keeping costly (due to EU CO2 emissions trade) coal plants going. Most other countries used renewables to replace coal plants while keeping existing nuclear around. Germany did the opposite.

But the international comparison is not as simple as the power price, there's a lot of infrastructure that is subsidized by other taxes and not power price directly. Not that those are any lower in Germany.
