energy management by technology
embyt started business in 2008 as an individual enterprise and continuously emerged over the years. We are located in Vienna, Austria and serve customers from small-size companies up to global players.
We have strong experience in energy monitoring and peak load management. We design and implement specific algorithms and have turn-key solutions available in this area. We complement our portfolio by peripheral products like providing web visualization or smartphone apps.
For customers with load metering, the energy consumption is continuously metered in ¼h steps. The maximum ¼h value of the year will be used as the factor for calculating the pricing for power. Typical power prices in Germany are approximately 50 € per kW and year. If the peak power value of a year is 200 kW, the annual power price is 10 000 EUR. By continuously checking the real time power consumption savings can be realized from utilizing dedicated, short switching techniques subsequently reducing the power of building loads such as air conditioning, compressors and heatings. Using the previous example, annual power peak may be reduced 20 to 25 %, resulting in annual savings of 2 000 to 2 500 €.
Particularly in the field of e-mobility, peak load management can avoid high costs due to the possible extremely high charging currents.
On sites with own power generation, e.g. thanks to photovoltaic systems, the embyt system is also ideally suited for self-consumption optimization, in addition to peak load regulation. If charging stations for e-cars are available, embyt can save energy costs by an optimal charging strategy.
The system consists of a central PLC controller and other IO modules. The figure shows an example with 4 connected modules. The energy meter (S0 interface) is connected to their inputs, and the energy consumers (loads) to be controlled are connected to their outputs, usually via contactors. This system automatically performs the peak load regulation. The embyt control software runs on a standard PC connected via LAN or Internet with the controller. The PC software is used for parameterization and visualization, while the peak load regulation runs autonomously on the controller. The embyt control software can be installed on any number of PCs in parallel, accessing all data of load management.
Peak loads that are well above the average consumption arise often by chance, when many large energy loads are unnecessarily switched on simultaneously. Oftentimes, heaters may be turned off for a short time without a noticeable deficiency. Also air conditioning or compressors can be switched off for some time as the cold is stored for some time anyhow. Similarly, many other loads can be located, which may be reduced in consumption under certain conditions at peak loads. The difficulty is to identify these loads and define conditions under which these loads may be turned off.
With the embyt Energy Management System these conditions are programmed graphically, so the system is completely self-sufficient to make appropriate interruptions at peak loads. The programming is carried out via an intuitive graphical system, so that no knowledge is required that goes beyond the knowledge of a skilled electrician.
With the PC software the energy use, load distribution and the costs may be evaluated in detail. For any irregularities the system automatically sends emails to one or more recipients.
The manual can be downloaded in the German language to describe the features and provide detailed instruction on how to use the PC software.

E-Mobilität is rising. More and more customers expect E-charging stations as a service.
Your cabling or the power provided is not enough for this?
The costs associated with the electrical peak power are too high?
empower allows charging stations without extensive costs. It provides flexible solutions, while still being easy to install. And it works self-optimizing.
Calculating the costs for peak power usage is not trivial. The amount is included within the network service costs and usually not explicitely stated. This is also the reason why many customers do not immediately face them and see the peak power costs as a potential for saving.
embyt provides a calculator, which allows calculation of energy costs including peak power. You can use real-life energy data from yourself and derive its costs. Even more, you can derive the savings from installation of an energy management system like empower.
