About OPTUM EBA
OPTUM EBA represents the energy procurement division of OPTUM GmbH, based in Heilbronn. We support companies and property management firms in considering consumption, contract terms, and purchasing models in a holistic context.
People who want to understand your business
A suitable energy contract begins with the right questions: What does your company need? What changes are on the horizon? How much predictability is required? Hasan Sahin and his team combine personal consultation with a structured review of your documents. Kamer Sahin is the managing director of OPTUM GmbH.
We want to make decisions understandable. This includes explaining price components, making variants comparable, and openly addressing the limitations of a model.
Our standards for working together
Hasan incorporates the questions from the consultation into the development of our digital tools. Our insight into OPTUM Pro demonstrates how personal experience and structured information work together.
Numbers only become a sound basis for decision-making when they align with day-to-day operations. Therefore, we analyze quantities, deadlines, and existing load profiles together with your objectives. Tasks, responsibilities, and terms are agreed upon before any engagement.
