KMEG Hansung City, Hansung City, Qingdao

City scale integrated energy masterplan

A new city is being developed in China as a joint venture between the Qingdao local government and Samsung C&T to develop a new mixed use city in the Huangdao district of Qingdao, Shandong Province.

The development will be first the to adopt the Micro Energy Grid (MEG) concept, combining Electric, heating, cooling energy networks to reduce energy consumption and carbon emissions. It will also decarbonise power supply and focus on savings through supply side measures. The city will utilise the SMART city principle through the use of extensive metering, sensors and controllers which can are centrally controlled to reduce peak demand and energy consumption.

Hansung City in Qingdao commissioned Arup to make a test site for micro-energy grid (MEG) technology in a bid to drive down carbon emissions and reduce costs. The proposed technology allows energy to be directed where and when it is needed. Carbon savings of up to 25% are forecast through the behavioural change that will come from simply knowing where every kilowatt hour of energy is being used at any one time.


The masterplan demonstrates that it is possible to run a city of 100,000 people on a micro-grid.

As the project is the first of its kind in the region, Arup wanted to ensure innovation was brought to every stage of the commission:

  • We enabled behavioural change in energy, through feedback and demand response
  • SMART city technologies were implemented allowing constant monitoring and feedback to stakeholders
  • Large scale electrical energy storage was implemented
  • Combined common services tunnel for infrastructure distribution was introduce
