Sustainable energy supply is the only basis for future prosperity and development. We believe in a technology-open and sustainable future of energy supply, in which energy is provided secure, affordable, and renewable. Smart integration of renewable energy conversion by the means of innovative technology is the key to a sustainable future. Our approach pursues the holistic integration of generators, electrical loads, and storages at all levels of energy systems. Technology openness belongs to our guiding principles, since individually tailored energy supply solutions will become the new energy supply reality rather than simply providing specific raw materials or energy carriers. This basic principle is also reflected in our software-as-a-service philosophy, as we support our customers with tailor-made and continuous IT services.
