xEMS the energy management system with the best use of M2M

Energy policy in Japan is now in a major transformation phase. This is due to the current trend in the rapid dissemination of solar photovoltaic (PV) power generation and electric vehicles (EVs), and also to the need to review nuclear power generation resulting from the recent Great East Japan earthquake disaster. In the future it will be more practical to control our electric power system balance more precisely by changing society and encouraging electricity generation at the point of use rather than by purchasing ever increasing amounts of electricity from the electric power companies. NEC is developing innovative EMSs to achieve an energy conscious society in the next generation. It is also optimally using the technologies that have been accumulated from our long-term experience in supervisory control system solutions for social infrastructure facilities. Our service platform technologies such as M2M and cloud computing engineering are also being expanded. This paper will introduce our approach to these developments.
