First, as long as the technology that is less expensive in the short run is subsidised, natural movements towards market equilibrium are suspended. Without subsidisation, renewable technologies with their high fixed costs would be the first victims of lower electricity prices due to their own low, short-term costs and investors would quickly hesitate to invest in them. Given the resulting impacts on system stability, investment conditions and consumer preferences, the resulting system costs may well be higher than in a system where dispatchable producers were unaffected from the price impacts of variable renewables.
