Knowra State Grid Corporation of China State Grid Corporation of China State Grid Corporation of China is a state-owned electric utility that operates most of mainland China’s power grid and ranks among the world’s largest utility companies.
Electric power transmission : The bulk transfer of electrical energy from generating stations to substations near consumers. State Grid operates the high-voltage network that carries electricity across regions.
Electric grid : An interconnected system of generators, transmission lines, substations, and distribution networks that delivers electricity. State Grid operates one of the world’s largest national electric-grid systems.
Ministry of Electric Power Industry : A Chinese government ministry that administered the electric power industry before its dissolution in 1998. Its dissolution preceded the creation of State Grid as a separate state-owned enterprise.
Renewable energy in China : Electricity and heat produced from renewable sources within China, especially hydropower, wind, and solar power. Grid capacity and transmission access influence how much renewable generation can reach consumers.
Ultra-high-voltage electricity transmission : Transmission of electricity at voltages typically at or above 800 kilovolts in alternating current or 1,000 kilovolts in direct current. Long-distance UHV lines move power from western generation regions toward eastern demand centers.
Load balancing : The continuous matching of electricity supply with demand to maintain stable grid operation. Dispatchers must balance changing demand against available generation throughout the network.
State Power Corporation of China : A state-owned Chinese electricity company formed in 1997 and dismantled during power-sector restructuring in 2002. State Grid emerged from the separation of the corporation’s transmission and distribution functions.
West-to-East electricity transmission : China’s policy and infrastructure programs for transferring electricity from western regions to eastern population and industrial centers. State Grid’s long-distance lines are a major part of these transfers.
Smart grid : An electricity network using digital measurement, communications, and control to coordinate power flows. Digital monitoring and automation help manage a vast, interconnected grid.
Power system control : The monitoring and regulation of electrical network conditions to keep supply reliable and within operating limits. Control centers coordinate line flows and respond to faults across State Grid’s service territory.
