Why be energy efficient?

Energy metering, monitoring and control technology systems reduce energy consumption—directly, through improved control and, indirectly, by making energy consumption ‘visible’ without requiring staff to read meters. They also enable benchmarking of energy usage and assist in the identification and evaluation of energy efficiency opportunities. The combined effect of motivating staff and revealing energy consumption patterns often leads to no-cost savings.

Recent developments in communications technology have helped bring costs down, making advanced metering a more viable proposition for medium-sized businesses. Advanced energy-metering systems link into control technologies to provide flexible, sophisticated control of energy-using systems according to varying conditions. They also improve control accuracy, including production yield, quality and consistency.

While this section of the website focuses on the use of energy metering, monitoring and control technologies, the Energy Management section of the EEX website provides information on the business processes required to manage and operate an effective system. This includes:


There are often energy efficiency opportunities from optimising existing energy metering, monitoring and control systems or in upgrading or replacing systems depending on system capabilities.

Case studies

  • Energy Efficiency at the University of Queensland 2013 (Opens in a new window)

    This case study describes how the University of Queensland reduced its energy consumption at its St Lucia campus by integrating energy management into their governance structures and improving its energy data analysis and systems.

  • Case Studies in Systems Optimisation 2013 (Opens in a new window)

    This document includes case studies of three companies that have applied a systems optimisation approach to their business to improve their energy productivity. The companies profiled are Simplot, AngloGold Ashanti and Worsley Alumina. The case studies demonstrate how systems optimisation can be used to improve energy efficiency and productivity in a wide range of industrial applications.
