Energy Economics Institute at the University of Cologne

What Energy Economics Institute at the University of Cologne does

The Energy Economics Institute at the University of Cologne (Energiewirtschaftliches Institut an der Universität zu Köln, EWI) is a non-profit research organization (gGmbH) and 100 percent subsidiary of the Cologne University Foundation, operating as a knowledge factory for European energy market economics. It is institutionally funded by the state of North Rhine-Westphalia as a member of the Johannes Rau Research Foundation (JRF) since January 1, 2022, and is led by Prof. Dr. Marc Oliver Bettzüge of the University of Cologne's Department of Economics.

EWI's core technology is a portfolio of more than a dozen proprietary computer-based models covering European electricity and gas markets, hydrogen, power-to-X, and global energy commodities. These include SOPHIAA (electricity market model), DINO (electricity and heat), HYEBRID (hydrogen-electricity hybrid systems), DIMENSION (energy system dimensioning and optimization), SPIDER (European gas transmission), TIGER (European gas market transmission), COLUMBUS (energy system expansion planning), TIMCO (time-series investment optimization), MEET (agent-based market behavior), and supporting tools such as the EWI Merit-Order Tool, EWI-Wärmekosten-Tool, EWI Global PtX Cost Tool, and EnTrans Tool. The institute applies operations research, agent-based modeling, and machine learning across these models.

EWI's revenue model is built on three roughly equal pillars: institutional funding from the state of NRW, publicly funded research projects, and fee-for-service consulting. Consulting services — including asset valuation, scenario modeling, market design analysis, regulatory impact assessment, strategic consulting, and workshops — are delivered directly to the German Federal Government, the State of NRW, European Authorities, large energy suppliers, municipal utilities, and industry associations. With approximately 40 employees and an annual budget of around 3.2 million euros, EWI monetizes its expertise through commissioned research, policy advisory, and publication of agenda-neutral analyses in leading academic and applied outlets.
