During the China Western Development, Ningxia Dam Power Plant has been enrolled in Ningxia “the Tenth Five Year Plan”, and been determined as a crucial power supply point in “West-East Power Transmission”. As the first-class thermal power plant in State Power Corporation, Ningxia Dam Power Plant has transmitted over 550 billion kWh. We, XD HI-TECH, depends on our resource advantages and signed Central air-conditioning energy-saving phase I, II projects with Ningxia Dam Power Plant.

Innovation and Win-Win Result

At the very beginning of the power plant phase I comes into service, we started to conduct research on the project, the power plant project is technically in-depth study and to learn about the environment of the project implementation and project specific. With the help of our technical solutions and rational resource utilization, we win the bid on power plant air conditioning project.
