The growth of industrial activities during the last decades and the diversity of industrial products require standards and common methodologies for building and integrating different parts. It is also required that working groups use the same terminologies and concepts needed for each domain. The Model Driven Engineering (MDE) approach aims to give an answer while using a high level method based on models and transformations. In this paper, we use the MDE approach to model ubiquitous systems. Those systems are composed of devices interconnected through various kinds of network and offer to get and send information. We present a model for this class of system and its use in the field of energy while studying real cases from our industrial partner Terra Nova Energy (TNE).
