Smart grids provide real-time information on the grid, perform actions when required without any noticeable lag, and support gathering customer consumption information. On the downside, smart grids however, provide an increased attack surface for criminals.
For instance, smart meters can be hacked to cut power bills as happened in Spain in 2014 or due to a DDoS attack or malware infection, communications and control of the network could be lost, causing an energy production halt and affecting several systems across borders.
