如果在电厂中安装数字计算机以监控处理操作，则可对应用程序进行扩展，以包括功率和能量监控。操作员可以利用能源和电力使用的数字显示来控制成本，同时保持治疗、质量和需求水平。电厂电费的四个主要因素包括能源费、燃料调整费、需求费和功率因数调整。这些都是关于降低成本的基本定义和建议的描述。包括8个参考文献、图表。

Where a digital computer is installed in a plant for monitoring treatment operations, the application can be augmented to include power and energy monitoring. The operator can utilize digital displays of energy and power usage to control costs while maintaining treatment, quality, and demand levels. Four major factors of the plant electric bill include energy charge, fuel adjustment charge, demand charge, and power factor adjustment. These are described with respect to basic definitions and recommendations toward cost reduction. Includes 8 references, figures.
