DEMAND RESPONSE: WHICH PLACE IN THE FUTURE ENERGY SYSTEM Peter SCHELL, VP REGULATORY AFFAIRES RESTORE DR, DSM, Market Design, Sustainable, Future, Security of supply Summary Everyone agrees that Demand Response (DR) will play a role in the future energy system. This article focus on exactly which place DR can and should play and on how to get there starting from today’s situation and market design. Résumé Tout le monde s’accorde à dire que la réaction à la demande (Demand Response – DR) jouera un rôle dans le futur système énergétique. Cet article se penche sur le rôle exact que la DR peut et devrait jouer, et sur la façon d’y parvenir à partir de la situation et de la conception de marché actuelles. Samenvattin g Iedereen is het erover eens dat Demand Response (DR) een rol in het toekomstige energiesysteem zal hebben. Dit artikel beschrijft waar de DR een rol kan en zou moeten hebben en wat er moet gebeuren om dat mogelijk te maken uitgaande van de huidige situatie en het ontwerp van de markt.

Demand Response: which place in the future energy system - Peter SCHELL INTRODUCTION Demand Response (DR) has been a buzz word for some time now and is a dominant topic in most positions expressed about the future energy system by the European Commission, ACER and CEER as well as authorities in most European member states. Belgium has been in the leading pack of this process which has culminated in the recent report by the CREG on the subject [1]. What those study lack to different degrees is a clear definition of what exact place DR will/can take in the future energy system and more importantly how this change to the energy system can be achieved. DR is not the solution to all issues so much is clear but in combination with increased intermittent renewable energy production, increased cross-boarder capacity and the transition of transport and heat towards electricity it can and should play a major role as soon as possible. 1 THE KEY CHALLENGE : RUNNING HOURS The one key challenge introduced by the transition towards a sustainable energy system is the running hours of the different components. In proportion to the maximum demand of the system the proportion of baseload is significantly reduced and the average running hours of all non-renewable “peak” assets also reduces significantly as illustrated in the following diagram Fig. 1: Qualitative evolution of cumulative load on Elia Network The black curve is the residual load on the Elia network for 2014. The green curve is the qualitative evolution due to the further evolution of intermittent renewable energy sources and the blue curve shows the impact of increased cross-boarder capacity. As is illustrated the challenge for the energy system of the future is to find sources of capacity that can be efficient with significantly reduced running hours compared to the past situation. These sources need to be economically efficient, sustainable and provide the required availability and reliability to guarantee security of supply.
