Tested in consultancy projects. Go to to read more.

Expertise Required

Engineers/ Consultants with knowledge of how complex energy systems or processes work.


Approximately 300 users mostly in Germany.


Process Engineers, Energy Consultants, Contractors and Operators, Researchers


Component based modeling and simulation of energy systems using graphical user-friendly interface. Data for components are required. The software is capable of working with both constant and time-dependent data.


Tabular and graphical representation of calculated results based on financial and ecological parameters. The software can generate Sankey Diagrams and automatic reports for further understanding of the user.

Computer Platform

Windows PC

Programming Language

Mainly C++


TOP-Energy can be used for a variety of other industrial processing apart from energy systems. The component or variant library that the modules are equipped with is being constantly expanded to cater to the individual needs of the users. You can easily integrate your own components or adapt the existing ones without much effort. Customized version of the software as well as consultation support is available if required.


Detailed simulation of production processes (esp. dynamic simulation is not included)
