Addressing energy shortage problem, is one of the most complex matters that the world is facing nowadays. Within this context, in contrast to northern European countries, the Belgian heat supply sector based on building and dwelling heating devices is mainly decentralized, while more efficient and centralized methods such as District Heating is scarcely found. However, during the last years the interest in District Heating projects has experimented a steady and growth. The evolution and development of such path has confronted and overcome varying challenges, policies incentives, market and society scenarios. The present paper provides an update of the District Heating sector in Belgium, with the focus on the development in the last 5 years. Even though there is a well understanding among much of the stakeholders about the necessity of increase the share of sustainable energy sources, there still are predominant some conflict of interest and disagreement about how to achieve this paradigm shift. Hence, this study assesses the prospect of the future increase of District Heating use in the country by mean of a multi-actor analysis perspective. The approach looks forward to systematically explore the system and actor dynamics, to gather synergy between all relevant actors and achieve a sustainable and feasible framework. The study indicates that multi-actor approach will strengthen cooperation opportunities, increase the attractiveness of the business model and will contribute to precipitate the transition to a sustainable energy base in the country.
