The level of sophistication automation can bring to a business’s energy management system is extraordinary. Equally impressive is the money (and energy) saved through implementation of a strategic demand control system. Look no further than Taking Control of Energy Use, an article recently published on InTech filled with examples of savings and energy conservation.

Common practice is for companies to pay a demand charge to utility companies based on peak demand. Enabling a system to moderate loads, reducing peak demand, can save thousands annually. Automation systems go beyond anything that can be achieved manually. Set to act in a specific fashion, intelligent energy management systems can root out inefficiencies, slow down cycling blowers and shut down battery charges as needed.

A key factor of energy management is reducing demand without affecting production. This is where the true brilliance of automation shines. A system can be built to react to countless factors and be programmed in such a way that it never modifies aspects of the business that need to be running at all times.

Envision every asset, tool and machine in a plant working and reacting to one another without the need for manual instruction. The whole system works in harmony, optimized to its best performance level. In order to achieve this improvement, an evaluation of the plant should be performed. This should involve identification of potential savings of the life of a system, saving opportunities and saving initiatives. It can be helpful to have automation experts evaluate your processes for you as they have been trained to notice every detail of a system. Pick the guys who will tell you the truth, not just the truth you want to hear, and you’ll be amazed at the funds you save after you achieve return on investment.

Savings Potential of Variable Speed Drives

Businesses often question the profitability of energy efficient investments and the speed of their return on investment. The fact is, the areas of a business that can most benefit from efficiency investments are unique. This article from Control Engineering Magazine, lists these areas among the many that have the greatest potential of financial and energy savings:

  • Supply voltage optimization
  • Power management solutions
  • Increased factory or process automation
  • Intelligent lighting control and low-energy lighting
  • Building controls
  • Monitoring and targeting systems
  • High efficiency motors
  • Variable speed drives

Variable speed drives, which include variable frequency drives or VFDs, are one of the simplest energy efficient devices a business can invest in. Using customer experiences and conservative predictions, Control Engineering detailed the potential financial savings over 5 years with VSD installation for 10 countries. The United States shows the greatest potential for savings.

VSDs can reduce energy consumption by 70%, with the most receptive applications being pumps, fans and centrifugal compressors. Other assets that can make use of these drives include mixers, centrifuges, reciprocating compressors and extruders.

Keep in mind, the above figure illustrates the savings potential of just one application, variable speed drives. Combined with other advancements in energy efficient technology, savings can rise even higher. There are plenty of energy efficient initiatives for industries to adopt.
