System Integration

In the "System Integration" business area, we deal with the transformation of our energy system into a target system without fossil fuels. This involves integrating renewable energies into the grid structures on the one hand and increasing the efficiency, flexibility and resilience of energy systems on the other: The solution lies in the cross-sector integration of energy systems in electricity, gas and heating grids with their diverse possibilities for storage utilization and flexibility options. Structural planning and management with the simultaneous provision of system services within the "electricity, heating, cooling and gas grids" infrastructure in the evolving energy market open up a comprehensive range of solutions for our customers from industry and the public sector.  

Our main areas of focus are 

  • Integrated networked energy supply concepts, so-called "on-site systems" with a high proportion of local and regional resources
  • Networked operations management for intersectoral, cross-divisional energy systems, digital integration into grid control systems and the energy market 
  • Intersectoral energy supply systems with distributed storage systems 
  • System simulation, combined heat and power, thermal and electrical storage and also hydrogen-based energy systems  
  • Digitalization: AI for system planning (energy system and grids), operational management and asset management 
  • Living labs: CO2-reduced energy supply in industry and the building sector, cross-media integration in electricity/heating/cooling and gas/H2 grids with flexibility management
