ewi ER&S - a "knowledge factory"

ewi Energy Research & Scenarios 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 ER&S 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 ER&S 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 ER&S creates energy-economic analyses with great practical relevance. The clients of ewi ER&S 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.
