All Suppliers know that winning and retaining customers is an expensive business. By adopting USEF, suppliers have an opportunity to better differentiate themselves from their competition by developing a range of new services. As well as creating new income streams, these will provide the means to make their brands more compelling to potential new customers. They will also deliver more interaction and, as a result, deeper relationships with existing customers. USEF unlocks the value of flexibility in a way that is closely related to current working procedures and offers a common standard for the development of new flexibility services. By building on this one common standard, solutions are more rapidly scalable and future connectability is assured.
