In a cellular energy system, the physical balance between energy supply and demand is established as far as possible at the local level according to the subsidiarity principle, and only the remaining residual load is balanced from outside. The sub-quarter of civil engineering has a single grid connection point to the superimposed campus grid and thus, from the grid operator's point of view, a simple structure. This enables a simple evaluation of the grid-related behaviour and the power exchanged at this grid connection point. In addition, a suitable system for operating the energy cell is already under construction here. Furthermore, additional PV systems will be built in the immediate vicinity.

The sub-quarter is home to high-performance electrical consumers such as the institute buildings or the test halls. This project will investigate a reduction in the base load through energy efficiency measures and a flexibilisation of the consumers in the operation of the energy cell. The low and medium voltage measurement infrastructure installed in phase II makes it possible to record and evaluate the grid status in order to utilise the grid more efficiently.
