Jeju island project is one of the first Smart grid test-beds set up around the world. Its objective is to optimise energy usage in 6000 homes. The smart grid – an intelligent power transmission and distribution system – will collect real-time data to limit unnecessary use of electricity and increase the efficiency of its consumption. It is a close public–private collaboration that should help Korean companies to achieve a leading position in the early commercialisation of smart grid technology. This example is useful around the world, as it tests the management of next generation utility networks and how they can be supported by modern IT platforms and communications networks.
