The interdivisional PSI Laboratory for Energy Systems Analysis conducts analytical research on diverse energy technologies and systems.
LEA is a cross-center laboratory bridging the Centers for Nuclear Engineering and Sciences (NES) and Energy and Environment (CEE). It unites specific analytical research on diverse energy technologies and systems, including nuclear, fossil and (modern) renewables. Taking an holistic and interdisciplinary approach, LEA develops models, analysis and tools to support decision makers and researchers to address complex and systemic challenges in the broad field of energy. LEA includes the groups Technology Assessment, Energy Economics, Risk and Human Reliability, and the Chair of Energy Systems Analysis at the Department of Mechanical and Process Engineering (D-MAVT) of ETH Zurich. The link between LEA and D-MAVT was established in 2022 by the appointment of the LEA Head, Prof. Dr. Russell McKenna.
The LEA areas of activities fall into three main areas:
Lab News & Scientific Highlights
Un modello di sistema energetico completo per la Svizzera
I sistemi energetici devono affrontare sfide complesse e a lungo termine, soggette a un elevato grado di incertezza. Il modello di sistema energetico STEM del Gruppo di Economia dell'Energia del PSI è diventato uno strumento importante per la ricerca di queste sfide e il supporto al processo decisionale.
I veicoli elettrici in Africa potrebbero prendere piede prima del previsto
I veicoli elettrici potrebbero diventare economicamente competitivi in molti paesi africani prima del 2040.
Energy systems modelling at LEA
The model that has been behind Switzerland’s most complete analyses of the energy transition is built and run by the Energy Economics Group at PSI’s Laboratory for Energy Systems Analysis.
