Our core competencies include consulting, simulation and monitoring. Specific services offered are, for example, the design, evaluation and optimisation of district and local heating solutions and the integration of renewable energies, storage facilities or charging infrastructures for e-mobility in existing energy systems. A unique selling point is the ability to map the real behaviour of energy systems as a whole within a multi-domain model or digital twin. With the help of the in-house, modularly expandable planning tool Green City for SimulationX, any scenarios; control and system variants or operating states can be tested and evaluated, quickly and precisely. The EA Systems service portfolio also includes server provision, big data processing and data preparation and visualization through API and cockpit development with a focus on transparency, plausibility and individualization, according to customer requirements.
