    Abstract: Introduces the initial objectives of GE smart meter joint venture jointly launched by State Grid Corporation, GE), Luneng Group and China Electric Power Research Institute, including the joint venture party, strategy, objectives and project progress. In addition, the GE Smart Power Technology Exchange meeting held by State Grid Corporation in China Power Research Institute on July 1,2009. The participants included leaders and experts of State Grid Corporation, China Power Research Institute, Luneng Group Company and GE Company. During the meeting, GE introduced its general situation, the technical status of smart meters and the application of WiMax wireless communication technology. The participants had in-depth exchanges on the technical issues of smart meters and raised questions that need further supplementary explanation. The GE smart Meter joint venture project is launched to build one of the top smart meter companies in the world. The technical cooperation between State Grid Corporation and General Electric Corporation (GE) of the United States is of special significance in the field of measurement. The author, as a historical witness and a participant in the technical negotiations, it is necessary to record this period of history.
