Internet of things can also be integrated with the Smart Grid, thereby enabling real-time energy optimization. Measurements, automated controls, plant optimization, health and safety management, and other functions are provided by a large number of networked sensors. The term industrial Internet of things (IIoT) is often encountered in the manufacturing industries, referring to the industrial subset of the IoT. IIoT in manufacturing could generate so much business value that it will eventually lead to the Fourth Industrial Revolution, so the so-called Industry 4.0. It is estimated that in the future, successful companies will be able to increase their revenue through Internet of things
Smart grid in China authorities a strong and robust smart grid market would total $20 billion annually by 2015. Rolling out Ultra-High Voltage (UHV) transmission systems would account for more than 60% of that market, while smart meters and wind power connectivity could reach $2 billion and $800 million annually respectively. SGCC has implemented these smart grid technologies in areas such as Liangjiang, with the project there passing inspection in Q3 of 2014. It currently comprises one 220 kV substation and seven 110 kV substations. SGCC also launched the first UHV power grid in Tianjin in November 2014. The project calls for 290 transmission
