Energy Consumption - “We have to measure it – to manage it”

Evaluating energy performance and reducing consumption requires good info-rmation on how, when, and where energy is being used. Collecting and tracking this information is necessary for establishing baselines and managing energy use. Understanding current and past energy use is how TITAN Roanoke Cement, US identifies opportunities to improve energy performance and gain financial benefits. In 2009 TITAN Roanoke Cement installed a real time energy monitoring system using a network of digital meters to monitor and track energy consumption and energy intensity for each process area of the plant. All metering data is available in a central database for plant management to review, plant energy team analyses energy trends during operation and shut downs to determine where and how energy improvement can be made. The energy monitoring system enabled the plant’s energy team to identify several energy savings opportunities, and in 2009 their cumulative efforts resulted in saving 10M kWh at a value of $490K.
