1. A method of limiting the power demand of a plant facility having controllable and non-controllable loads by switching said controllable loads during demand periods and selectively in accordance with a pre-established priority list, comprising the steps of:

  • assigning at the beginning of each demand period a demand limit to be met at the end of such demand limit;

    deriving an indication of the actual demand of power by said plant facility at the end of a demand period;

    establishing said demand limit at the beginning of a given demand period by reference to the indication of an actual demand recorded during one demand period preceding such given demand period;

    predicting a demand at the end of said given demand;

    deriving a demand error by reference to said established demand limit and with said predicted demand; and

    switching said controllable loads selectively during said given demand period to minimize said error.
