73. Application – Financial Summary Investment for the Smart Energy Management System: (including power analyzers, communication, IT) 230 000 € Investment for Solutions: (incl. max. demand, dynamic PFC, active harmonic filter, …) 455 000 € Total Investment: 685 000 € Saving of Energy cost: Reduction of maximum demand charges 75 000 €/p.a. Reduction of energy sourcing from the spot market 50 000 €/p.a. Reduction of kWh consumption 180 000 €/ p.a. Reduction of maintenance cost: 45 000 €/ p.a. Reduction of drives and equipment failures: 75 000 €/ p.a. Saving due to avoiding production stops: 70 000 €/ p.a.* Total Savings: 495 000 €/p.a. Return of investment: 1.4 years (*) Comparatively low figure considered as it was not very clear before the installation of the SEMS which production stops were related to PQ problems! Probability is high, that this figure could be five times higher.

74. Application – Client Summary Dr. Schmidt, Factory Engineer, summarized as follows: “This energy management project shows that often, like in life the root causes are not that simple to identify and require intensive work, but the hard job pays off and over the long term earns a lot of money for the Company. Overall we are very satisfied with the SEMS, especially the Janitza electronics UMG measurement devices and the software provided by Janitza. Furthermore the after sales service as well as the application support was most important for the successful conduction of this project! As we are a global enterprise we are now thinking about the next step, introducing a global SEMS including all of our production sites across four continents.”

75. Summary

77. Easy monitoring of energy consumption

78. Easy reporting of energy consumption, with detailed information and breakdown of data

79. Reviewing of power utility bills

81. Benchmarking of various production lines in a factory, buildings, factories of an international enterprise, shops of a commercial enterprise (e.g. Mc Donalds)

82. Transparency of the energy distribution system

83. Create awareness for energy saving

85. Peak demand management system (for active reduction of high demand charges)

86. Active control of loads with devices such as UMG604 (e.g. light control in an office tower, switch off all lights during night, active air-condition control with the temperature input, time control of large compressors to avoid peak loads at critical busy times of the day, ...)

88. Identification of over-load scenarios before the process of the client is stopped

89. Stabilisation of process, avoiding production stoppages or break down of equipment

90. Root cause analysis when a failure has occurred

91. Alarm management, e.g. THD-V is too high, send an email to the engineer

92. Power Quality Solutions specification based on the monitoring results and detailed data and facts recorded

93. Data and evidential proof of short term voltage interruptions or other PQ problems for claims against the power utilities
