In cases with a production tax credit (PTC) applied to wind power, solar energy would be curtailed before wind, as curtailing wind output means forfeiting the tax credit—but overall, total renewable curtailment rates are nearly identical with the PTC. As shown in the graph, nuclear flexibility significantly reduces renewables curtailment.
