| Pumping systems comprise almost 25 percent of all motor energy usage in building and HVAC, water and wastewater, oil and gas extraction and transportation, and irrigation applications. Efficient pumping systems can save users more than 50 percent in potential energy costs.
In addition, electrical energy costs represent 40 percent of the total cost of ownership (TCO) of pumping systems (see Figure 1). Yet organizations struggle to leverage cost reduction through efficiency improvements. The following major barriers need to be recognized and addressed:
◦Energy efficiency has traditionally not been a primary focus for assessing system performance. In most organizations, energy utilization has only just been introduced as a corporate metric.
◦A lack of awareness in overall pump system energy efficiency opportunities is common. As a result, potential savings and other benefits have been missed.
◦Lack of funding has resulted in operations personnel struggling to present attractive investments to their senior management.
An energy management plan reduces pumping systems'TCO while maintaining sustainability objectives.
