By the analysis of our hospital in energy utilities, in order to establish the basic data of electricity consumption. Once these dates have been collected, the promotion of energy consuming efficiency can be heaved by managing electricity and appraising power potency to achieve overall energy expense disbursement. The paper further analyze the structure of power vs price to help to retrench a large mount of power expenditure by carrying out power management, reasonable contract capacity, escalating power work ratio, selecting appropriate electricity computing mode, establishing air conditioner facility, applying discount power price. This strategies not only shift the peak power load but also balance the power unility in Taiwan, reducing the establishment of new power plant and the impact of nature environment as well as the in convenient curb on power consumption.
