3. "The current demand (or "load") depends on how much power consumers are using right now. While the load changes every time someone switches a light on or off, the sum of loads due to a large number of consumers varies slowly. In addition to the supply needed to meet this demand, some "reserve" generating capacity must be kept ready to operate in case of any unexpected events." Supply and Demand For Electricity, Berkeley Lab.
