Energy Management Systems serve primarily the purpose to visualize the energy consumption, evaluate it and finally optimize it. This approach is valid for every company regardless the sector.
Sector-specific are the methods to measure the energy consumption value. It has to be decided which communication technology should be used, which intervals are suitable (15-minute grid up to single-second intervals) and which values need to be recorded. Also the evaluation, the indicators (EnPI) and optimization possibilities are often specific for each sector and company.
