Energy System Technology

Energy system technology delivers solutions for effectively using and expanding renewables, supply networks, storage systems and electromobility.
A special role plays the re-design of the transmission and distribution grids. The coupling of electricity, heat, gas and transportation enables the necessary increase in flexibility between energy generation and energy demand.

We develop the necessary structural and planning methods, operational strategies, equipment, system technology, control engineering and energy management systems. Our research facilities allow standardization and client-specific components and system tests.

Grid Planning and Operation

Already more than one million distributed generators are connected to the distribution grid in Germany. In addition, more and more loads and storage systems are also integrated into grid operation.

The multi-sector approach (electricity, heat / cold, gas, mobility) has to be consistently implemented in order to achieve minimum costs for the entire energy supply when investing in the grid infrastructure and operating it.

We are an experienced partner and service provider in all topics of grid planning and grid operation.
