envisaged as part of the smart grid initiative
mixture of multiple systems/ applications
possible benefits, it is important that each of these systems support the minimum need of being able to talk to each other i.e. should be INTEROPERABLE
identify the key use cases in these functionalities, and the corresponding information exchange needs
