Whenever an increase in wind power or reduction of consumption reduces the amount of power drawn from a coal fired power plant, the following steps of cause and effect occur: 1) less load is placed on the generators, 2) less steam is required to turn the generators, 3) less heat is used to turn water into steam, and, 4) less fuel needs to be burned to keep the boilers hot.
