Peak Hours
In the United States, peak hours usually occur in the afternoon, especially during the summer months when the air conditioning load is high. During this time many workplaces are still open and consuming power. Peak hours can also occur in the evening after work hours, when household appliances are heavily used.
A peaker plant may operate many hours a day, or it may operate only a few hours per year, depending on the condition of the region's electrical grid. Because of the cost of building an efficient power plant, if a peaker plant is only going to be run for a short or highly variable time it does not make economic sense to make it as efficient as a base load power plant. In addition, the equipment and fuels used in base load plants are often unsuitable for use in peaker plants because the fluctuating conditions would severely strain the equipment. For these reasons, nuclear, geothermal, waste-to-energy, coal, biomass and electrochemical energy storage systems are rarely, if ever, operated as peaker plants.

Famous quotes containing the words peak and/or hours:
“In all things I would have the island of a man inviolate. Let us sit apart as the gods, talking from peak to peak all round Olympus. No degree of affection need invade this religion.”
—Ralph Waldo Emerson (1803–1882)
“In the middle of the night, as indeed each time that we lay on the shore of a lake, we heard the voice of the loon, loud and distinct, from far over the lake. It is a very wild sound, quite in keeping with the place and the circumstances of the traveler, and very unlike the voice of a bird. I could lie awake for hours listening to it, it is so thrilling.”
—Henry David Thoreau (1817–1862)
