The highest electric requirement including Losses experienced by an electric system in a given period (e.g., an hour, a day,
month, season, or year). It is equal to the sum of the metered (net) Power outputs of all Generators within a system and the metered line flows into the system, less the metered
line flows out of the system. Thus, actual peak demand is the maximum
(usually hourly integrated) demand of all customers demands plus losses. Usually
expressed in mega-Watts.
