The only interesting part is that renewable production in Europe is so random that there can be far too much for short periods.

The wholesale price system is not a reliable signal or incentive for electricity generation supply and demand in Europe. There are various subsidies, taxes, levies, and fixed costs not shown at the wholesale level that completely change calculations.

These numbers will make customers upset and complain about price gouging if they don't understand the disconnect. Or, it makes customers think that renewables are cheap because they are not seeing the subsidies that on net result in higher payments to renewable providers than carbon-based producers.
