Aggregation offers increased savings to participants as a result of combining each member's energy requirements into a larger buying block. In order for the aggregation to be effective, it must offer potential-suppliers benefits that result in lower energy costs for the members. These Benefits Include:

Predictability of Load: By properly compiling load data, the aggregation provides suppliers with greater predictability. With greater predictability, the supplier can better manage their energy purchases. Another contributing factor to load predictability is the consistency (flatness) in which the load is used by the members. The flatter the load, the lower the price. The more the load consumption fluctuates, the higher the price is likely to be. Aggregations that can balance their load profile with members of different usage patterns can help flatten their overall load-shape.

Size of Load: More is better. Larger blocks of power are easier for suppliers to acquire and move.  Reduced Costs of Marketing: An aggregation offers potential suppliers the opportunity to serve a large volume of customers at a fraction of the cost of marketing to them individually.

Additional Services: By serving the aggregation's electricity needs, the supplier has a unique opportunity to offer additional services to the members including demand management.
