First Underground Smart Power Station in Xiongan to Start Operation

The main body of the first underground smart power station in the Xiongan New Area was recently capped, confirming that the station is ready for trial operation.

Located to the southwest of the Xiongan high-speed railway station, the power station is the central source of energy in the affected area.

Featuring two layers, it has no enclosing walls and visitors are able to have a close look at it including its operation and maintenance through an underground observation corridor.

The station has three 46 megawatt gas-fired hot water boilers with a supporting waste heat pump system, which form a heat supply pipeline network to provide low-carbon, environmentally-protective and economical energy to the region.

It's worth mentioning that all power supplied by the station is based on clean energy.

Devices for recycling of the waste heat of the gas fume as well as the waste water and waste material and a combined system for heat and power production will lower operation costs and improve the utilization rate of energy to more than 70 percent.

A storm sewage treatment facility has also been designed in the station. The filtered water will be sprayed for dust prevention and concrete curing and is estimated to meet nearly 50 percent of local industrial water demand.

In addition, the electric boiler and heat storage systems are reserved for future coordinated operation with other renewable energy sources such as geothermal energy and solar and wind power.

The project is contracted by China Construction Industrial & Energy Engineering Group Co., Ltd., a subsidiary of China State Construction Engineering Corporation.

During construction, innovative technologies including unmanned aerial vehicles, city information modeling and building information modeling were used to reduce modification and demolition, cutting down the construction period by nearly 20 days.

As a smart energy demonstration project in Xiongan, the station upon completion is expected to meet heating and cooling demands in an area of 4.02 million square meters and to promote a coordinated energy pattern to realize safe supply of clean power based on electric, natural gas and thermal energy.
