By 2030, Belgium is expected to lower its non-ETS greenhouse gas emissions by 35% compared to 2005 levels. The energy problem is prominently present in the Belgian news nowadays, especially a possible extension of the lifetime of nuclear reactors is a highly debated topic among politicians. However, this question represents only a part of the problem, the overall challenge of a transition towards a sustainable and cost effective energy future is much more complex. For instance, more than 80% of our heating demand is covered by fossil fuels, while also the transport sector is still heavily reliant on gasoline and diesel. Introducing electric vehicles and heat pumps can reduce greenhouse gas emissions, but presents challenges for the current electrical grid. As the electricity generation is increasingly covered by renewable energies such as solar and wind energy which are not continuously available, the energy market is evolving to a system where more flexibility is needed. With this project we want to support policy makers with facts and figures, increasing the level of the energy debate.

We need energy models which take all aspects of the energy system into account. Energy models shed light on the most cost effective way to reduce greenhouse gas emissions, maintain a continuous supply of electricity and heat and still keep the consumer’s energy bill under control. Technological parameters are taken into account, such as the decreasing price of battery storage and renewable energies, but also the role of regulation (for instance subsidies for heat pumps, renewable energies or renovation), market actors (producing and selling electricity) or consumers play an important role.

A lot of knowledge and expertise is present in Belgian research institutes on energy modelling. Different models are used, such as techno-economic investment models, generation dispatch models, market models, transport models, building models etc. The goal of the EPOC 2030-2050 project is to combine the expertise of the Belgian research community by linking the different energy models, carefully discussing the input data used and applying them to the Belgian situation. This will support policy makers in their decisions with respect to the energy future in Belgium towards 2030 and 2050. The overall approach of the EPOC 2030-2050 project presents is a first-of-a-kind in the Belgian energy sector, never before have such a wide range of academic partners collaborated in one energy modeling research project. The project is coordinated by EnergyVille, and the participating research institutes are: VITO, Imec, KU Leuven, UHasselt, ICEDD, the Federal Planning Bureau, WaterstofNet, Transport & Mobility Leuven, Ugent, UMons, KMI (Het Koninklijk Meteorologisch Instituut van België), UCL, ULiege and ULB. A wide range of Belgian stakeholders have already committed to support the scientific project work and will contribute by validating the input parameters used in the models and by critically reviewing the results of the models which will outline potential energy pathways for Belgium.
