Perlwitz, HolgerCail, SylvainMöst, DominikRentz, OttoHřebíček, J.Ráček, J.2019-09-162019-09-162005https://dl.gi.de/handle/20.500.12116/27455In the last decade, the European energy supply sector has faced far-reaching structural changes such as market liberalisation and stronger environmental laws that have led to new market structures and a new competitive environment. The ongoing discussion on emission reduction targets and climate change mitigation strategies threatens to cause new modifications for energy supply companies. This paper presents two PERSEUS-CERT3 model upgrades which focus on the interdependencies among decisive developments in the energy market, especially in the context of emission reduction strategies. These are, on the one hand, a more detailed representation of the European gas supply sector and, on the other hand, a sophisticated representation of demand side measures to increase energy efficiency.Text/Conference Paper
