Test Motors not only helps you to reduce your maintenance costs and make your company more productive, efficient and safe; it also helps you make it more environmentally friendly.

In the event of unforeseen downtime in a production process, despite the fact that the plant stops to produce paper, cement, steel, petroleum products or energy, it continues to consume electricity. The energy it consumes is far less than usual, but it is not using it to produce anything; it is simply being used to maintain indirect services and processes, i.e. residual energy consumption. Therefore, the plant is being totally unproductive.

Test Motors, thanks to its products and services, helps you to carry out the predictive maintenance of your production process, which will drastically reduce unscheduled downtime and, like that, energy wastage (residual energy consumption). That translates into a reduction of CO2 emissions in the atmosphere.


How much does a plant consume when not producing?

The intensive electricity consumption per unit produced in the different industries is as follows*:

  • Cement plant: 114 kWh per tonne of cement produced
  • Paper plant: 674 kWh per tonne of paper produced
  • Metallurgical plant: 535 kWh: per tonne of steel produced
  • Petroleum refinery: 99.4 kWh per tonne of crude oil treated
  • Water treatment station: 0.5 kWh/m3 of reused water (wastewater treatment plant) and 5 kWh/m3 of treated water (desalination plant)


We will estimate that the residual consumption of a production plant equals 30% of the plant’s consumption when producing. If, as a mean value, we take 72 hours as the amount of unforeseen downtime in production plants per year, the amount of electric energy wasted is as follows:

  • Cement plant: 4,186 kWh – 1.1 tonne CO2/year
  • Paper plant: 293,000 kWh – 78.1 tonne CO2/year
  • Metallurgical plant: 145 kWh – 0.038 tonne CO2/year
  • Petroleum refinery: 1,717 kWh – 0.45 tonne CO2/year
  • Water treatment plant: 1.3 kWh – 0.0003 tonne CO2/year


By implementing the predictive maintenance of the electric motors or generators of your production process under the guidance of Test Motors, you will reduce unscheduled downtime to near zero and you will avoid emitting several tonnes of CO2 into the atmosphere.
