A group of reservoirs may be obligated to meet the power demands of preferred customers before this energy is used for other purposes. For example, if a group of reservoirs is owned by another entity, the energy demand of their customers must be met before the energy is coordinated with the other reservoirs in an economic objective, and in this sense, their customers are preferred. In such a situation, some— perhaps all—of these reservoirs are also treated as allocated energy that can be flexibly used in coordination with the remaining reservoirs.

The methods in this category model the energy needs of the preferred customers. The preferred customers are identified by membership in a “Preferred Customer” subbasin. This is a predefined type of subbasin.

See Preferred Customer in Objects and Methods for the methods in this category.
