Germany’s Klimanachrichten reports on the recent phenomenon of extreme negative electricity prices on the European power exchange, specifically highlighting the role of solar energy (photovoltaics) in this development.

Being weather-dependent, it’s become almost impossible to match supply to demand. Sometimes the prices go negative.
According to Klimanachrichten, electricity prices at the exchange reached new record lows in the negative range. This occurs when the supply of electricity significantly exceeds demand, and producers must effectively pay consumers to take the power off the grid.
A primary driver for this surplus is the massive expansion of solar power. During periods of high solar radiation (sunny days) combined with low weekend or holiday demand, the grid gets flooded with “must-take” renewable energy and there’s an increasing difficulty to balance the power grid. Unlike traditional power plants, which can be throttled more easily, the fluctuating nature of solar and wind requires complex interventions to prevent grid overloads.
Because renewable energy operators are often guaranteed a fixed feed-in tariff regardless of market prices, the “gap” between the negative market price and the guaranteed remuneration must be covered by subsidies (often financed through taxes or levies). Since solar owners often receive money even when their electricity has a “negative value,” there is little incentive to invest in storage technologies like batteries.
Klimanachrichten has long since been critical of current energy transition (Energiewende) policies, arguing that the rapid expansion of weather-dependent renewables without adequate storage or flexible demand leads to massive economic inefficiencies and puts the industrial base at risk due to high system costs.
“The record negative prices are the market’s loudest warning signal that we have an oversupply of unstable generation, but a dramatic lack of flexibility and storage capacity,” Klimanachrichten summarizes.
The article suggests that the current subsidy model is unsustainable and calls for a shift toward a system where renewable energy producers are more exposed to market risks, incentivizing the synchronization of production with actual demand.

” producers must effectively pay consumers to take the power off the grid.”
If I understand: Citizens are taxed to pay some (Who?) consumers, with the producers taking a cut on the pass-through.
Has anyone asked the tax-paying citizens if they like this situation?
2nd question: How is power “taken off the grid” if there is no demand for it?
I imagine that “power is taken off the grid” means that the generators are braked or disconnected from the grid. In other words, the producers are paid to NOT supply electricity.
