Universal, Distributed, Flexible Energy Management Solution


Why OpCo EMS?

Know your expensesKnow your expenses
Specific knowledge of the consumption of electricity daily, hourly or by functional areas, is a prerequisite to plan and implement certain measures in order to save electricity. Such measures may be the replacement of equipment with high energy consumption, reconstruction of parts of the electricity infrastructure and creating systems for manual or automatic reduction of the power consumption.

Have you ever wondered why the expenses you make in the supermarket magically decrease right after you start to write down everything you spend? Or why when you drive and the display of the board computer shows the fuel consumption you instinctively start to drive more economically. The studies show that the psychological effect of monitoring the energy consumption alone, leads to reduction of the expenses between 5 and 7%!

Save your equipmentSave your equipment
Often there are cases of serious damages caused by the bad quality of the electricity used. If the repair of the expensive equipment costs several thousands, everyone would like it not to be repeated again. Observe and analyze the quality parameters of the electricity in order to be able to diagnose and eliminate the causes of such breakdowns before they occur.

The requirements imposed by laws and regulations, concerning the daily and even hourly prognosis of the necessary electricity, become more and more strict. On the other hand, planning is the most important step in managing every process, including the consumption of energy. The only way to respond to the challenge and not suffer unnecessary losses is to have an up-to-date and detailed statistics, to base your prognosis on.

System architecture


  • The lowest level of the system architecture is built by network analyzers which are directly connected to important points in the company’s infrastructure and are responsible for gathering all necessary parameters of the electricity.
  • Each network analyzer is connected to a software module called Collector which is responsible for gathering and buffering the raw data. The protocol used for communication is MODBUS over TCP/IP or over RS482.
  • All collectors are connected to the main engine of the system which is gathering and storing the data into a central database.
  • Web-based user interface is used from end-users to retrieve different reports and live data from the server.


Easy and fast configuration

This important parameter of OpcoEMS leads to easy and rapid deployment of the system in different environments without the need of special software development for each scenario. Configuration is available for the following system parameters:

  • The client company as hierarchical structure of different workshops and departments, internally called functional zones;
  • Electricity parameters which are meaningful for the system;
  • List of measuring points.
    Measuring point is a place in the infrastructure where a network analyzer is installed and connected to the power supply chain of specific functional zone.
    Configurable for each measuring point are:
    • Functional zone for which the point is gathering data;
    • What parameters are measured and what kind of historical data is gathered on the server;
  • Calendar with tariffs with prices for converting consumed energy to finances.

Monitoring of real time data

Values for all configured parameters, measured by a network analyzer in specific measuring point, are read from the corresponding Collector and then sent to OpCoEMS engine. Each client connected to the system can view in standard web browser all of those values in real time (the scan interval can be configured starting from 100 milliseconds).

Live data

Parametrized history gathering. Reports and statistics over history data

The user can configure separately how history data is collected for each energy parameter in each measuring point (network analyzer). Configuration includes:

  • Types of history data collected for the parameter;
  • On what time interval data is written to the database for each kind of history gathered;
  • How long is history kept in the database before garbage collector clears it.

Aggregate history

Types of history which the server can gather for each parameter are:

  • Snapshot of current parameter value;
  • Minimal, maximal and average value of the parameter during time interval;
  • Accumulated value of the parameter (energy consumed);
  • Events.


OpCoEMS offers different reports based on data gathered. The information can be filtered and grouped by functional zones, time periods, measuring points, parameters etc. Formulas for indirect calculation of energy consumption for functional zones which are not directly covered by measuring point also can be configured.


Costing of energy

OpCoEMS generates reports not only for energy consumption values but also for energy costs. This is done using configured data about different energy tariffs supplied by the domestic energy company.
