The European Electricity Market Model EMMA

Summary. The open-source Electricity Market Model EMMA is a techno-economic model of the integrated Northwestern European power system. It models both dispatch of and investment in power plants, minimizing total costs with respect to investment, production and trade decisions subject to a large set of technical constraints. In economic terms, it is a partial equilibrium model of the wholesale electricity market with a focus on the supply side. It calculates short-term or longterm optima (equilibria) and estimates the corresponding capacity mix as well as hourly prices, generation, and cross-border trade for each market area. Technically, EMMA is a linear program with six million non-zero variables. It is written in GAMS, and solved by Cplex on a desktop computer in about ten minutes. EMMA has been used for eight peer-reviewed publications to address a range of research questions. It is also used for consulting projects.

Publications

A wide range of publications base on the EMMA model. These include academic articles in economics and engineering journals, including single-author papers in the leading field outlets Energy Economics, The Energy Journal, and Applied Energy. Publications using the model have won several awards, including the best paper award of the International Association for Energy Economics. [icon type=“icon-right-dir“]
