Preparing now for the electricity systems of. Preparing now for the electricity systems of tomorrow... Concept Grid is a full-scale smart grid test facility designed to anticipate and facilitate the transition from electricity distribution systems to smart grids. Built as a closed circuit, but representing real power transmission grids, Concept Grid makes it possible to conduct a range of grid optimisation scenarios in complete safety (with automatic reconfiguration response to faults, incorporation of renewables, optimisation at peak demand, etc .) . The many benefits offered by this test facility include the ability to conduct complex stress tests under challenging conditions, which would be impossible on a live network serving real-life customers.
