Calculating the capacity of an elec

Calculating the capacity of an electricity grid - the amount of energy it needs to supply to
users- might seem simple. Just add up the power supplied over a given period of time to give the
total amount consumed by users. Then, divide the cumulative amount of power used during the
whole period by the number of hours in the period. The result is an average level of consumption
per hour. But there's one problem with this method - and it's a major one.
The rate of power consumption - the amount that's being consumed at a particular moment -
is not constant. In other words, consumption does not stay at the same level all the time. So electricity
supply requirements cannot simply be averaged out over time. People use more power at certain
times of day, and less at other times, which means that demand for power fluctuates significantly.
Generally, it rises to a maximum in the evening (peak demand is at evening mealtimes), and falls to
its lowest levels during the night. These fluctuations are so big that at peak times consumption can
be twice as high as it is during off-peak times. Clearly, the grid needs to have sufficient capacity to
meet demand when consumption peaks. But since each peak is brief, the grid will only run to
capacity - at or close to its maximum capability - for a few moments each day. This means, most of
the time, it has significant spare capacity
