Decision security
When energy contracts expire, the right decision counts.
For industrial companies, electricity and gas procurement is a management decision with long-lasting effects. I make sure you take it on solid ground — with a clear tender, a genuine offer comparison, and an award recommendation that holds up in front of management.

Your consultant
Advice on an equal footing — built on more than twenty years of practice.
From switchgear sales at ABB through leadership roles at municipal utilities and energy suppliers to sales leadership at ENGIE Deutschland: I know both sides of the negotiating table — and have brought that experience to bear as an independent consultant and trainer since 2025.
Sharing knowledge
Seminars that make the energy industry understandable.
From the fundamentals of the energy industry through the EEG, KWKG, and EnWG to industrial electricity pricing and energy sharing: practice-oriented seminars for education providers, municipal utilities, industry, associations, and the property sector — in-house or open, in person or as a webinar.
