Who we are

As the owner-managed company Inercomp, we have been working for our customers since 2008. Ever thereafter we have expanded our services with the experience of more than 20 years in the energy industry. We are leading experts for the energy market as well as for energy supply contracts with a focus on wholesale trading of electricity, natural gas and CO2-certificates.

Each one of our approximately 20 team members has expert knowledge in sub-sectors of the energy industry. Together, we form a team that covers the entire spectrum of the energy industry. We are particularly united by our shared values of independence, sustainability and transparency.

Accuracy, fun at work and open communication are important principles of our daily work: in the team and with our customers!

Our typical customers include international industrial groups, including some of the largest companies in Central Europe, with an annual consumption ranging from 10 gigawatt hours to several terrawatt hours. We have been serving them on a long-term basis and in close cooperation. But also smaller energy consumers, power producers and energy suppliers rely on our support. We are happy to provide an extract of our reference projects on request and upon consultation.

Company history


Our values


Our services are based on wide-ranging energy industry know-how, transparent calculations, forecasts and an independent opinion. We do not sell you any energy, do not receive any success commissions and therefore deliberately do not benefit from your savings. The remuneration corresponds to pre-defined fees. You receive an honest and unbiased opinion from us.


We meet the challenges of the energy revolution and the associated business models with confidence, enthusiasm and passion. But we also have an important dose of energy realism. We are committed to actively exemplifying sustainability: from the company's own electric car to the use of public mobility and the compensation of CO2 emissions that have been unavoidable to date.


Our analyses and evaluations form the basis of your decision. A transparent preparation of our services and results is a matter of course for us. Knowledge transfer to our customers plays a major role in this. Our work for you is a matter of trust.
