Electricity supply has to match demand. But demand changes over the course of a day. Suppliers need to generate more electrical energy when demand is high. And they need to generate less when demand is low. In other words, suppliers need to avoid undersupply and oversupply.
What is the supply of electricity?
All power supplies have a power input connection, which receives energy in the form of electric current from a source, and one or more power output or rail connections that deliver current to the load.
