Dr. Johannes Truby

Partner, Deloitte France | Deloitte Economic Advisory

Dr. Johannes Trüby is a partner in Deloitte France, where he leads the Energy Markets and Modeling team of Deloitte Economic Advisory. 

He provides quantitative analyses and specialized knowledge in energy markets (e.g., forecasts, scenarios, economic impact of energy policies) as well as assessments of the regulation of energy infrastructure (e.g., benchmarking, tariff design, weighted average cost of capital (WACC) calculations, regulatory and market design) to private and public clients. He has more than 15 years of energy sector work experience, acquired in consulting with an international organization and a development bank.

Before joining Deloitte France, Johannes led the natural gas, coal, and parts of the power market outlook of the International Energy Agency’s (IEA) flagship publication, World Energy Outlook (WEO). He was responsible for the design of the analysis and ensured the economic coherence of the long-term energy trends and scenarios. Johannes contributed to the dissemination of the findings and regularly defended the WEO’s energy trends at workshops and conferences, and on industry panels globally.

During his six years at the IEA, Johannes advised governments around the world on strategic energy policy, especially in terms of economic impact of environmental policies, regulation, and market design. Moreover, he worked with energy companies to help develop strategies on how to mitigate stranded assets in light of decarbonization policies.

Johannes co-authored several IEA publications on decarbonization (Energy and Climate, Redrawing the Energy-Climate Map), environmental policy (Energy and Air Pollution), regional studies (India Energy Outlook, Southeast Asia Energy Outlook, China Energy Outlook and Africa Energy Outlook), and the role of investment for a secure, clean and affordable energy future (World Energy Investment Outlook).

Prior to joining the IEA, Johannes spent three years with the Institute of Energy Economics (EWI), a specialized energy economics think tank in Cologne. While at EWI, he advised the German government on the economic impacts of its “Energiewende” policy and assessed the economic implications of the nuclear phase-out decision in 2011. Johannes studied economics at the University of Cologne. In his PhD thesis, he analyzed price formation in international coal markets.
