About Stefan

Stefan is a senior partner in McKinsey’s Vienna office. He works across the entire energy and multi-utilities space from oil and gas upstream to power generation, power distribution and water networks.

Stefan’s clients include international oil companies, public and private utilities, as well as environmental service and technology groups. His recent client work includes advising on the following:

  • multiyear transformation of a major municipal water department, delivering more than 10 percent savings across the entire water operation and resulting in abated tariff increases
  • multiyear transformation of upstream operations of an international oil company, increasing production while lowering capital expenditures and lifting cost per barrel
  • growth strategy for an integrated energy company resulting in significant portfolio shift toward profitable upstream
  • industrial water strategy for a global environmental group to unlock value for their customers in oil and gas, metals and mining, and food and beverage through new and innovative water and waste technologies and solutions
  • the transformation of distribution network operators, improving customer service while reducing cost

Stefan is also involved in our research into water scarcity, and recently participated in a study which developed an outlook on water scarcity and mitigation strategies up to 2050.

He holds undergraduate and master’s degrees in computer science and industrial engineering from Karlsruhe Technical University and an MBA from IESE Business School, University of Navarra.
