We model better together: EPOC, PATHS 2050 and the future of Belgian energy

How will our energy system evolve in the coming years and decades? Is a safe, affordable and carbon-neutral energy supply possible by 2050? And what can or needs to be done for that? These are the core questions that formed the motivation for the EPOC 2030-2050-project, and which researchers from no less than 13 Belgian institutions have been considering for almost five years. And in doing so, the project also delivered something new, thanks to EPOC 2030-2050, Belgium now has a virtual expertise and data centre on energy. ‘Our overarching energy model brings all the relevant sectors together. Moreover, it is tri-regional: we can separately zoom in on Brussels, Flanders and Wallonia,’ says project coordinator Pieter Vingerhoets from VITO/EnergyVille.

The core of the project was what is called the TIMES-model: an energy model that seeks cost-efficient solutions based on technical or economic preconditions. These may be security of supply, or carbon-neutrality by 2050, while including affordability for citizens and companies. The model was adapted to the Belgian energy context, and to the three regions as well. ‘TIMES-BE, our Belgian TIMES-energy model, is indeed tri-regional: it can also be used specifically for Brussels, Flanders and Wallonia,’ says project coordinator Pieter Vingerhoets. ‘This is very important, as there are of course significant differences between the regions. Flemish industry differs from Walloon, for example, and the same applies to mobility and transport.’ At the same time, the overarching Belgian TIMES energy model takes account of interactions between the regions in terms of energy. ‘In that sense, you can view it as a helicopter model.’ And that helicopter aspect can also be found in the way in which the Belgian TIMES energy model brings the various relevant sectors together. ‘In contrast to earlier modelling work, TIMES-BE now takes more account of important, energy-intensive industries – such as the chemical, cement and steel industry.’ The integrated nature of the Belgian TIMES energy model therefore allows us to do direct modelling work for specific regions or sectors. The consequence is results that are objective,  and very reliable, precisely because EPOC 2030-2050 also enjoys broad support. Vingerhoets: ‘As an energy expert, I personally find this the most important gain from this project: for the first time, it brought our entire Belgian research community together.’

One example of data that the TIMES-energy model can produce is investments needed for reducing greenhouse gas emissions. For the regions, it can help them achieve their climate-neutrality ambitions. The same applies for industrial sectors and their attempts to become more sustainable. But the energy model is useful for many more reasons. Policy-makers can use it to help sketch out the future of the Belgian energy system (or parts of it). And for companies and sectoral federations – such as Febeliec, which commissioned VITO/EnergyVille for the PATHS 2050-research – it can supply crucial information for strategic decisions. ‘Energy-intensive companies would prefer to know where they stand in terms of energy supply today, rather than tomorrow,’ says Vingerhoets. ‘Take electricity prices, for example. In recent years, this has been highly volatile, and how this will evolve remains fairly unclear. The price also depends upon policy decisions, such as taxes, tariffs and the market model used.’ Partly due to this benefit to industry, the EPOC partners will continue to update their TIMES-BE-model in the coming years, so that questions from the business world can continue to be answered. 

The EPOC collaboration thus leaves behind a virtual expertise and data centre in terms of energy, which will continue to be a breeding ground for new joint ventures after the project ends. There is large interest in this kind of service provision, as it happens, which was revealed in the response from several major stakeholders like essenscia, Fluxys, Engie and the FPS Economy, which all turned up on 9 May 2023 at Thor Park, Genk, for EPOC’s closing event.
