Customer� The end-users of electricity
� Connected to the electricdistribution networkthrough the smart meters.
� The smart meters controland manage the flow ofelectricity to and from thecustomers and provideenergy information about
Customer Domain
energy information aboutenergy usage and patterns.
� Each customer has adiscrete domain comprisedof electricity premise andtwo-way communicationsnetworks.
� A customer domain mayalso generate, store andmanage the use of energy,as well as the connectivitywith plug-in vehicles.

Operations� Manages and controls theelectricity flow of all otherdomains in the smartgrid.
� It uses a two-waycommunications networkto connect to substations,customer premisesnetworks and otherintelligent field devices.
Operations Domain
intelligent field devices.
� It provides monitoring,reporting, controlling andsupervision status andimportant processinformation anddecisions.
� Business intelligenceprocesses gather datafrom the customer andnetwork, and provideintelligence to support thedecision-making.

Markets� The Markets domain operates
and coordinates all theparticipants in electricitymarkets within the smartgrid.
� It provides the marketmanagement, wholesaling,retailing and trading of energyservices. The Markets domaininterfaces with all otherdomains and makes sure they

domains and makes sure theyare coordinated in acompetitive marketenvironment.
� It also handles energyinformation clearinghouseoperations and informationexchange with third-partyservice providers.
� For example, roaming billinginformation for inter-utilityplug-in-vehicles falls underthis domain.

Service Provider
� smart grid handles allthird-party operationsamong the domains.
� These might include webportals that provideenergy efficiencymanagement services toend-customers, dataexchange between the
Service Provider Domain
exchange between thecustomer and the utilitiesregarding energymanagement, andregarding the electricitysupplied to homes andbuildings.
� It may also manage otherprocesses for the utilities,such as demand responseprograms, outagemanagement and fieldservices.
