Peaking power plants, also known as peaker plants, are
power plants that generally run only when there is a high demand, known as
peak demand, for
electricity. In the
United States, this often occurs in the afternoon, especially during the summer months when the
air conditioning load is high. The peak power load generally occurs between 4pm and 5pm when people return home from work, start cooking dinner, and turn up the air conditioning. During this time many workplaces are additionally still open and consuming power.
