With more than 280 smart grid projects and 90 smart metering pilots and counting in 30 countries across Europe, it is clear that there is already considerable activity under way in this region. These are the projects that have usefully been collected into a single database by the European Joint Research Centre, from which a good overview of what is being done by whom may be gleaned (p. 90). In particular a few interesting points emerge. One is that the size of projects and number of project participants is generally increasing, which is positive in terms of technology scalability and maturity. Another is that an increasing number of projects are being carried out on a multinational basis, which enhances opportunities for sharing not only of the outcomes but also the costs.
