The Smart Grid Project in Sino-Singapore Tianjin Eco-city was started in April, 2010. The project planed six substations, two 220kV and four 110kV. Finally, a smart power supply network will be formed with 220kV and 110kV transmission network, 10~35kV distribution lines and 380V/220V low voltage distribution networks .
The total load in Tianjin Eco-city is estimated to 411.25MW, i.e. 12.02MW/km2 load density. The renewable generation will take 24.62% of the total generation to meet the planning requirements of the Eco-city.
The total investment of the Eco-city has reached 369.9 million RMB, (about 54.6 million USD). The project will be finished at least 80% by the end of 2010 and finalized by the end of 2011. 
The Smart Grid Project in Tianjin Eco-city will include:
Intelligent distributed power generation systems with grid energy storage and diversified access;
Intelligent transmission systems with line digitization, standardization and safety;
Intelligent substations with integrated digital information and communication platform for networking, information sharing, standardization, advanced interactive applications;
Intelligent distribution network with intelligent self-healing, flexible, adjustable intelligent based on distribution automation;
Intelligent end use containing information collection system, two-way interactive marketing system, intelligent power district, building, home and electric car charging and discharging station;
Intelligent control and operation center with intelligent operational risk assessment, early warning and coordinated control of power supply security and optimal scheduling functions;
Dynamic multi-dimensional virtual visualization platform to provide the smart grid with geographic information integration, analysis and visualization function for operation .
