The necessity of establishing a user-energy management system（U-EMS） is detailed in terms of energy saving and load transfer. On the basis of describing expectable functions and experimental environment， a U-EMS archetype system is designed including the hardware part and software part. The former consists of smart sockets， data receiving and dispatching modules， RS-232 serial to Ethernet module and server; the latter consists of data receiving and dispatching side， server side， PC side and smartphone side. The basic functions have been realized， including electricity power acquisition of electric equipment， electric equipment opening and disconnection， calculation of total power consumption and so on. Further， the system operation condition is described， and the next stage development and direction of research are pointed out.
