Lublin University of Technology teams up with business and local government again – this time with focus on energy

The Lublin University of Technology has teamed up with with MPK Lublin (Municipal Transportation Company) and Tele-Fonika Kable Group to design a modular energy storage system for businesses. The project will see three pilot energy storage schemes: one located on the site of the university to conduct functional research, one in a production plant of TFKable, and another one on the premises of MPK Lublin bus and trolleybus depot.

A letter of intent on this collaboration was signed on 24 March by Rector Zbigniew Pater, Chairman of the Board of MPK Lublin Tomasz Fulara and Head of Research and Development of Tele-Fonika Kable SA Jakub Siemiński.

The energy storage will consist of containers with the option to connect a few or a dozen devices in parallel to increase the total capacity and/or power, depending on the user’s needs. The storage will be universal, i.e. it can be connected both to 3-phase low-voltage network and to a DC network, for instance to a traction network that supplies trolleybuses – says Dariusz Zieliński, PhD Eng from the Chair of Electrical Drives and Machines at the Lublin University of Technology.

Thanks to the solutions the energy storage will allow for optimization of power and energy consumption, which will translate into the reduction of the company’s connection power and savings relating to the reduced peak load. The solution will be intended for the enterprise sector and will respond to the necessity to reduce energy consumption. It is an issue in the light of planned regulations, according to which businesses will be charged an additional fee depending on the duration of the full connection power load in relation to the company’s working time (on a daily basis).

Thanks to this project, we will be able to use the stored energy. In companies like MPK Lublin, the problem is very visible, because the peak power consumption is over 1500 kW, while the average daily consumption sits at 70 kW. This generates huge costs, resulting from the supply of connected load by the utility company. The proposed storage is intended to cover part of the energy and power demand at times when there are peak loads on the grid. As a result, the daily load curve will be flattened and it will be possible to reduce the total connected load of a facility – says Tomasz Fulara, Chairman of the Board of MPK Lublin.

The project of developing the mobile energy storage is one of the strategic directions of development of TFKable Group.

They are a natural addition to the offer dedicated to RES i.e. medium- voltage cables for offshore and onshore wind farms. Importantly, the functionality of this solution will include the possibility to connect them to a photovoltaic farm, which will allow to reduce electricity losses by eliminating the need to turn it off due to, for example, a voltage increase in the grid. Thanks to this solution, it will be possible to significantly increase the self-consumption rate of photovoltaic parks – adds Jakub Siemiński, Head of Research and Development of Tele-Fonika Kable.
