EWI - a "knowledge factory"

The Institute of Energy Economics (EWI) at the University of Cologne is not-for-profit and considers itself to be a “knowledge factory”, dedicated to creating, spreading and utilizing new knowledge on increasingly complex energy markets. The energy world is currently experiencing a dramatic transition as a result of changing political and social environments as well as new technologies and innovations. These developments pose intricate questions, for which EWI hopes to find answers through practical, unbiased research with a strong foundation in energy economics.

In order to gain the most knowledge for academic, political and energy economic applications, ewi ER&S uses cutting-edge economic methods. Alongside theoretical economic analyses, EWI focuses on applying and developing quantitative methods. This includes detailed, computer-aided models of the European electricity and gas markets, as well as global energy markets such as coal and oil. EWI creates energy-economic analyses with great practical relevance. The clients of EWI include public institutions such as the German Federal Government, the State Government of North Rhine-Westphalia, European authorities as well as private companies, such as large energy suppliers as well as municipal utilities and associations.

Prof. Dr. Marc Oliver Bettzüge is the temporary managing director, leading a team of approximately 35 colleagues. In addition to the revenue from research projects, analyses and expert reports for public and private clients, research activities are further financed by donations from a not-for-profit sponsoring association.


The Society of Benefactors of the Institute of Energy Economics at the University of Cologne e. V. is the sole shareholder of EWI. The society exclusively pursues non-profit and academic goals, in particular the promotion of science and research in the field of energy economics.
