Wind curtailment is the deliberate reduction of electricity output from wind turbines, despite their capability to generate power under existing wind conditions. This practice is typically implemented by grid operators to maintain the stability of the electrical grid or to address specific operational constraints.

"paid to turn off" Wind energy providers in some countries are compensated for curtailment, this a form of subsidy for renewables. It can be payed directly by the goverment, or it is added to the price of electricity for consumer.

My understanding is that all inverters sold at this moment, in the EU, need to have demand response and grid curtailment mechanisms by law.
