Energy demand and load-shifting. Utility companies (the industry that provides energy to us all) are regulated by the state government and are expected to have the capacity to supply energy on demand. Energy demand by individuals, entire cities, and entire states varies depending on the time of day, the season, and the overall climate. Having the capacity to meet maximum demand means that there is excess capacity during off-peak times of the day when electricity is produced but not used. Since energy is difficult to store in large quantities, load-shifting helps to reduce the quantity of unused power over a 24-hour period. Q11.
