The Technoeconomics of Energy Systems laboratory (TEESlab) is an independent research unit in the University of Piraeus (UNIPI) in Greece. Our highly skilled team of experts conducts interdisciplinary research, working on the fields of energy system modelling, policy analysis, and technoeconomic assessment of energy systems. By employing both quantitative and qualitative techniques, we develop innovative and sustainable business models, and we study critical issues of the transition to climate neutrality by 2050. Our mission is to address real-world problems to support a wide spectrum of stakeholders and end-users, including the actual policymaking world (from regional and national governments to the European Commission), the energy industry, the academia, and citizens. Our solution-oriented attitude acts as the core element towards the generation and dissemination of scientific knowledge and the provision of useful, pragmatic, and evidence-based guidance to our clients. Overall, we aim to create an open and constructive dialogue between market players and the research community to produce robust scientific outputs that will have an impact on the wider society!
