However, they may well constitute the impacts most acutely felt by electricity producers and may in the long run have the most profound effect on the operations and structure of electricity markets. Table 1.1 provides a first indication of the losses in load factors. It shows that those most heavily affected in the short run are the technologies with the highest variable costs, which are hit hard by the unavoidable decline in electricity prices due to the influx of 10% or 30% of electricity with zero marginal cost that will push the supply curve towards the right. In the long run (not included in Table 1.1), the situation changes as high fixed cost technologies will leave the market because of reduced numbers of full load hours.
