Florida implements first large-scale smart grid

MIT Technology Review : Smart grids consist of series of smart meters networked with thousands of sensors at key power-grid features such as substations, transformers, local distribution lines, and high-voltage transmission lines. Although dozens of utilities have installed some smart-grid components, Florida Power and Light is the first to implement a wide variety of devices on a large scale. The advantage of smart devices is that they enable utility companies to locate problems before they cause an outage and that they limit the extent and duration of an outage once it has occurred. Also, smart grids weather storms better than conventional grids and allow for easier installation of intermittent power sources, such as solar or wind. The Florida grid cost $800 million, $200 million of which came from the US Department of Energy. DOE is currently analyzing the impacts and costs of its smart-grid projects for possible improvements in operating efficiency and customer participation.
