The smart grid revolution demands a huge effort redesigning and enhancing current power networks, as well as integrating emerging scenarios such as distributed generation, renewable energies and the electric vehicle. This novel scenario will present a huge flood of data that can be only handled, processed, and exploited with the help of cutting-edge ICT technologies. We present here the ENERGOS project that fully addresses this evolution, and detail accurately how it will deal with the challenges posed by the smart grid paradigm.
