Alexander Roth

Alexander Roth is a postdoctoral researcher and economist at DIW Berlin (German Institute for Economic Research) and KU Leuven, specializing in energy economics and the decarbonization of the energy sector. He is affiliated with the Department of Energy, Transport, and Environment at DIW Berlin, where he conducts empirical and numerical research on electricity market flexibility, sector coupling, and the integration of heat into power systems. He is also actively involved in public engagement through the energy policy podcast 'fossilfrei' and the EU-focused podcast 'EU Untangled'.

His research interests include:

• Energy transition and decarbonization
• Electricity market design and flexibility mechanisms
• Integration of renewable energy sources
• Energy storage and long-duration storage solutions
• Climate policy and sector coupling
• Power system modeling under high renewable penetration

Recent publications highlight trends in energy system modeling, policy evaluation (particularly of Germany’s 'Ampel' coalition energy policies), and the technical and economic implications of renewable energy integration. His work often focuses on system-level challenges such as 'Dunkelflaute' events (prolonged low-wind/solar periods) and the role of demand-side flexibility in ensuring grid stability. He frequently collaborates with Wolf-Peter Schill, Claudia Kemfert, and other leading energy economists.

Awarded no specific scientific prizes mentioned in the text, Roth contributes extensively to policy consulting and public discourse. He has advised on mechanisms such as the reliability reserve and capacity markets, and his work informs energy policy at national and European levels.

He supervises no listed students but is involved in collaborative research projects such as Ariadne, OpenEnergyTracker, and the DIW Bridge Project 'SichER'. He previously worked at the European Commission’s Climate Action Department and the Brussels-based think tank Bruegel, bringing practical policy experience to his academic work.

Roth holds a PhD in economics from the Technical University of Berlin and studied in Mannheim and Brussels. His interdisciplinary approach combines economic modeling, empirical analysis, and policy evaluation to address the complex challenges of the energy transition.
