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
