Through the construction of new energy and green power, we can optimize energy structure and reduce the cost on purchased electricity; through sophisticated metering analysis, we can identify abnormal leaking &wasting of energy; through equipment transformation, we can implement management and control more efficiently, hence reducing energy consumption and costs; through remote monitoring, work order management and automatic meter reading, our operation and maintenance become more efficient; through early warning analysis and fault diagnosis &recovery, the safety in energy use can be secured.
