Energy Effiency

Contribution of Energy Monitoring

Energy efficiency and energy monitoring go along with one another. The process of measuring, following, and assessing energy use in a facility is referred to as energy monitoring. On the other hand, energy efficiency refers to minimizing energy waste and optimizing energy utilization within a facility.

Energy monitoring offers a thorough insight of how much energy is utilized in a facility, which may be used to spot inefficient and wasteful energy use. Energy monitoring may give a thorough picture of energy use and assist facilities in finding possibilities to increase energy efficiency by evaluating energy use in real-time.


Energy monitoring is applicable to many different forms of rotating machinery, including motors, pumps, compressors, and other kinds of mechanical machinery. Facilities can identify spots where energy is being wasted, such as equipment that is misaligned, overloaded, or running outside of its ideal range, by monitoring the energy consumption of these components.

Additionally, by keeping an eye on the energy usage of rotating equipment, facilities can see opportunities to enhance the performance of these parts, such as slowing down pumps outside of peak usage times or realigning motors to use less energy. By using energy saving techniques, facilities can increase the energy efficiency of all rotating equipment and minimize energy waste. According to the techniques used, chronic problems can be prevented by determining which equipment or process originates from the energy waste.

To illustrate the impact of energy monitoring on maintenance costs with an example, compressed air leaks are an important source of wasted energy in air systems in industry. 25-30% of the compressed air at the compressor outlet is wasted due to leaks on the line. In a well-maintained system, the percentage lost due to leakage should be less than 10%.

The operating cost of an air compressor is more than the initial purchase. Industrial air compressors consume a lot of energy. When they are not working as efficiently as they should, some of this energy use does not contribute to the operation of the facility. If 170 m3/h of air is needed and the leakage level stays at 30%, 220 m3/h of air must be produced to compensate.

For reference, an air compressor consumes an average of 20 kW of energy per 170 m3/h. Therefore, producing 50 m3/h more to compensate for the air loss increases the energy cost by about 30%. The Compressed Air and Gas Institute (CAGI) estimates that a 6mm leak could cost you $2,500 to $8,000 per year. While the increase in energy consumption in the compressors can be monitored by energy monitoring, on the other hand, it allows root-cause analysis to be made on the side of whether the increase in energy consumption from the current and voltage signals used in energy monitoring is due to gas leakage in the line or a fault on the machine.

Promoting Sustainability

Sustainability may be greatly aided by energy monitoring in the industrial sector, especially for rotating machinery. Energy monitoring offers useful information on energy use, which may be used to execute energy-saving measures that both directly and indirectly lower carbon emissions related to energy production.

Energy Monitoring

Energy monitoring can also encourage the industrial sector to embrace green technology. Facilities can evaluate the effectiveness of various energy-saving measures and decide which technologies to install to further increase energy efficiency by monitoring energy use over time. This can involve implementing energy-saving technology, such as energy recovery systems.

By offering data-driven insights into energy use, energy monitoring of rotating equipment in the industrial sector may assist facilities in achieving their sustainability goals. Facilities may effectively promote sustainability by reducing carbon emissions, financial and environmental costs of energy by putting energy-saving measures into place and utilizing green technology.
