The relatively low utilisation of these peaking generators (commonly, gas turbines were used due to their relatively lower capital cost and faster start-up times), together with the necessary redundancy in the electricity grid, resulted in high costs to the electricity companies, which were passed on in the form of increased tariffs.
Relativno niska iskorišćenost ovih peak "generatora" (obično, gasne turbine korišćene su zbog relativno niže kapitalne cene i bržih startnih vremena), zajedno sa neophodnom redundancijom u elektroenergetskoj mreži, doveli su do visokih troškova za kompanije za električnu energiju, koje prenose se u vidu povećanih tarifa.
