What problem it solves
The open-source Electricity Market Model EMMA is a techno-economic model of the integrated north-western 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 long-term 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.
